--------------------
Incompatible changes
....................
* On Max OS X the value of *PATHNAME-ENCODING* is set to UTF-8 and cannot
be changed because Mac OS X pathnames are UTF-8 strings, not byte sequences.
See <http://clisp.org/impnotes/encoding.html#path-enc> for details.
* Module WILDCARD has been removed.
Functions WILDCARD:MATCH and WILDCARD:WILDCARD-MATCHER are deprecated
in favor of POSIX:FNMATCH and POSIX:FNMATCH-MATCHER.
See <http://clisp.org/impnotes/syscalls.html#wildcard> for details.
* Module REGEXP:
+ Function REGEXP:REGEXP-EXEC no longer accepts :BOOLEAN argument; use
:RETURN-TYPE 'BOOLEAN instead.
See <http://clisp.org/impnotes/regexp.html#re-regexp-exec> for details.
* Module RAWSOCK:
+ Function RAWSOCK:CONVERT-ADDRESS now returns byte vectors instead of
integers.
See <http://clisp.org/impnotes/rawsock.html#rawsock-convert-address>
for details.
Improvements
............
* Mixing &OPTIONAL and &KEY in the same lambda list is a bad design
and now triggers a STYLE-WARNING during compilation.
See <http://clisp.org/impnotes/compilation.html#key-optional> for details.
* Redefinition warnings are now of type STYLE-WARNING.
Some CLOS warnings are now of type STYLE-WARNING.
See <http://clisp.org/impnotes/evaluation.html#suppress-check-redef>
and <http://clisp.org/impnotes/mop-clisp.html#mop-clisp-warn>
for details.
* FFI now converts REALs to FLOATs automatically as necessary.
New customizations
..................

See <http://clisp.org/impnotes/terminal.html#readline-extend> for details.
New features
............
* New declaration DYNAMICALLY-MODIFIABLE disables GF-ALREADY-CALLED-WARNING.
See <http://clisp.org/impnotes/mop-clisp.html#mop-clisp-gf-dynamically-modifiable>
for details.
* Function EXT:STREAM-HANDLES returns the OS file handles for the stream.
It has been present since 2.36 in package SOCKET but was not documented.
See <http://clisp.org/impnotes/socket.html#so-handles> for details.
* To help distributors distribute memory images of clisp applications in
package repositories, clisp has three new command-line options:
$ clisp [-K linking-set] -memfile-hash
Prints the hash code of the mem file binary interface.
$ clisp [-K linking-set] -memfile-hash-of mem-file
Prints the hash code of the mem file binary interface that was used to
create this mem-file.
$ clisp [-K linking-set] -memfile-compatible mem-file
Returns 0 or 1, depending whether this mem-file is compatible with the
linking-set or not.
See <http://clisp.org/impnotes/image.html#images-in-distros> for how to use
these options.
Modules
.......
* New module ASDF (based on the upstream version 3.2.0) provides a system
definition facility. See <http://clisp.org/impnotes/asdf.html> for details.

the installation directory for the VIM files (lisp.vim).
The default value is ${datadir}/vim/vimfiles/after/syntax/.
Thus, lisp.vim is now installed by "make install", and should
be included in the 3rd party distributions.
+ Top-level configure now always runs makemake, and makemake no longer is
a "user-level" command; do not run it unless you know what you are doing.
This brings the CLISP build process in compliance with the GNU standards.
+ We now use gnulib-tool to sync with gnulib (not really user visible,
but a major infrastructure change).
* Portability:
+ Support for ancient systems with broken CPP have been dropped.
This includes AIX 4.2, Coherent386, Ultrix, MSVC4, MSVC5.
+ NeXT application (GUI) code has been removed. Plain TTY is still supported.
* Module Berkeley-DB now supports Berkeley DB 4.5 & 4.6.
* Bug fixes:
+ FORCE-OUTPUT breakage on MacOS X when stdout is not a terminal (bug#421).
+ Fixed *PRINT-PPRINT-DISPATCH* binding in WITH-STANDARD-IO-SYNTAX (bug#425).

* New module libsvm interfaces to <http://www.csie.ntu.edu.tw/~cjlin/libsvm>
and makes Support Vector Machines available in CLISP.
See <http://clisp.org/impnotes/libsvm.html> for details.
* FASTCGI:GETENV is now compatible with EXT:GETENV and can return the
entire environment as an alist.
* The same internal interface now handles FFI forms DEF-CALL-OUT and
DEF-C-VAR regardless of the presence of the :LIBRARY argument.
(:LIBRARY NIL) is now identical to omitting the :LIBRARY argument.
The default for the :LIBRARY argument is set by
FFI:DEFAULT-FOREIGN-LIBRARY per compilation unit.
See <http://clisp.org/impnotes/dffi.html#dffi-default-lib> for details.
* Bug fixes:
+ DOCUMENTATION on built-in functions was broken on some
platforms (bug#369).
+ Fixed FFI callbacks, broken since the 2.36 release.
+ Fixed the way the top-level driver handles the "--" option terminator.
+ Fixed COMPILE of APPLY in LABELS for local function (bug#372).
2.40 (2006-09-23)
=================
Important notes
---------------
* All .fas files generated by previous CLISP versions are invalid and
must be recompiled. This is because DOCUMENTATION and LAMBDA-LIST are
now kept with the closures.
Set CUSTOM:*LOAD-OBSOLETE-ACTION* to :COMPILE to automate this.
See <http://clisp.org/impnotes/loadfile.html> for details.
User visible changes
--------------------
* Infrastructure
+ Top-level configure now accepts a new option --elispdir which specifies
the installation directory for the Emacs Lisp files (clhs.el et al).
The default value is ${datadir}/emacs/site-lisp/.
Thus, clhs.el at al are now installed by "make install", and should
be included in the 3rd party distributions.
+ Top-level configure now accepts variables on command line, e.g.,
./configure CC=g++ CFLAGS=-g
* Function PCRE:PCRE-EXEC accepts :DFA and calls pcre_dfa_exec() when
built against PCRE v6. See <http://clisp.org/impnotes/pcre.html>.
* New functions RAWSOCK:IF-NAME-INDEX, RAWSOCK:IFADDRS.
See <http://clisp.org/impnotes/rawsock.html>.
* When the OPTIMIZE SPACE level is low enough, keep function
documentation and lambda list.
See <http://clisp.org/impnotes/declarations.html#space-decl>.
* Bug fixes:
+ Make it possible to set *IMPNOTES-ROOT-DEFAULT* and *CLHS-ROOT-DEFAULT*
to local paths, as opposed to URLs (bug#344).
+ Fix the evaluation order of initialization and :INITIALLY forms in
then extended LOOP (bug#351).
+ Do not allow non-symbols as names of anonymous classes (bug#354).
+ REINITIALIZE-INSTANCE now calls FINALIZE-INHERITANCE (bug#353).
+ Fix the RAWSOCK module on big-endian platforms (bug#355).
+ PRINT-OBJECT now works on built-in objects (bug#337).
+ ADJUST-ARRAY signals an error if :FILL-POINTER is supplied and non-NIL
but the non-adjustable array has no fill pointer, as per ANSI (bug#360).
+ MAKE-PATHNAME no longer ignores explicit :DIRECTORY NIL (thanks to
Stephen Compall <s11001001@users.sourceforge.net>) (bug#363).
+ Executable images now work on ia64 (thanks to Dr. Werner Fink
<werner@suse.de>).
+ MAKE-PATHNAME on win32 now handles correctly directories that start
with a non-string (e.g., :WILD) (bug#364).
+ SOCKET-STREAM-PEER and SOCKET-STREAM-LOCAL had do-not-resolve-p
inverted since 2.37.
+ Set functions with :TEST 'EQUALP were broken on large lists (bug#368).

--------------------
* SAVEINITMEM now accepts :SCRIPT argument that disables interpreting
the first positional argument as the script name; and :DOCUMENTATION
argument that is printed by the new -help-image command line option.
See <http://clisp.org/impnotes/image.html> and
<http://clisp.org/impnotes/clisp.html#opt-help-image> for details.
* FFI:UINT64 and FFI:SINT64 are now compatible with C's long long type.
* Stack overflow detection and recovery finally work fine on Unix.
Libsigsegv is required for this, on all platforms (including MS-Windows).
CLISP should neither exit nor crash under infinite recursion.
If your distribution has CLISP compiled without libsigsegv, report
the missing feature to its maintainer.
Note that libsigsegv 2.4 is required, there are bugs in libsigsegv 2.3!
* It is now possible to specify the default method-combination of a generic
function, to be used when the DEFGENERIC form does not specify the
:METHOD-COMBINATION explicitly, through a default initarg specification
for the :METHOD-COMBINATION keyword on the generic function class.
* Readline completion works with non 1:1 terminal encodings, e.g. UTF-8.
* WITH-KEYBOARD works with the terminal even when SLIME hijacks *TERMINAL-IO*.
* I/O operations on Win32 are now much faster.
* New functions: POSIX:FFS, POSIX:PATHCONF.
* Infrastructure:
+ Top-level configure now accepts a new option --with-gmalloc to use the
GNU malloc implementation instead of the one supplied by libc.
You may need it on older HP-UX and newer OpenBSD systems.
See file unix/PLATFORMS for more information.
+ The value of the environment variable CFLAGS is respected by configure.
* Bug fixes:
+ SOCKET:SOCKET-SERVER :INTERFACE now behaves as documented.
+ EXT:READ-BYTE-NO-HANG and SOCKET:SOCKET-STATUS used to hang on
buffered binary sockets.
+ Allow DESTRUCTURING-BIND (a . b) with circular and dotted lists.
+ ADJUST-ARRAY of zero length adjustable string now works.
+ TIME now reports correct results when the heap grows over 4GB.
+ RAWSOCK functions now handle :START/:END arguments correctly.
+ BDB:DBC-GET now accepts :READ-COMMITTED and :READ-UNCOMMITTED.
+ POSIX:GROUP-INFO and POSIX:USER-INFO now handle errors correctly.
* Portability:
+ Support DragonFly BSD.

* SAVEINITMEM can create standalone executables.
Thanks to Frank Buà <fb@frank-buss.de> for the idea.
SAVEINITMEM also accepts :NORC argument to disable RC-file loading.
See <http://clisp.org/impnotes/image.html> for details.
* POSIX:SYSLOG no longer recognizes "%m" and other formatting instructions.
For your safety and security, please do all formatting in Lisp.

* Signal a continuable error when an already opened file is opened again,
unless both streams are read-only.
* SOCKET-SERVER now accepts :BACKLOG and :INTERFACE arguments.
The first (optional) argument should be the port number or NIL.
Use (SOCKET-SERVER NIL :INTERFACE SOCKET) instead of (SOCKET-SERVER SOCKET).
Thanks to Tomas Zellerin <zellerin@gmail.com>.
See <http://clisp.org/impnotes/socket.html#sose> for details.
* EXT:HTTP-PROXY now uses the environment variable "http_proxy", like
curl does, not "HTTP_PROXY", to avoid confusing it with CGI arguments.
* OPEN :DIRECTION :OUTPUT now creates write-only handles and treats
named pipes correctly.
* Fixed EXT:SETENV on non-POSIX systems (woe32 and BSD derivatives).
* Fixed a bug in EXT:! on 64-bit platforms.
Thanks to Dr. Werner Fink <werner@suse.de>.

--------------------
* Infrastructure:
+ Top-level configure now accepts the option --enable-maintainer-mode
that affects autoconf-related Makefile targets. The default value
is determined based on the presence of the CVS directories.
+ When libsigsegv is not found, print instructions on getting/building
libsigsegv and bail out; override with --ignore-absence-of-libsigsegv.
+ When --with-dynamic-ffi is supplied, but the FFI fails to build, abort.
+ When --with-readline is supplied, but GNU readline is not found, abort.
+ makemake no longer checks with_module_* variables.
* New function EXT:OPEN-HTTP and macro EXT:WITH-HTTP-INPUT.
See <http://clisp.org/impnotes/macros3.html#open-http> for details.
* New declaration EXT:NOTSPECIAL undoes the effects of DEFVAR and DEFCONSTANT.
See <http://clisp.org/impnotes/declarations.html#notspec-decl>
for details.
* Function EXT:CLHS is now deprecated in favor of DESCRIBE, which can now
point your web browser to the ANSI CL and CLISP-specific documentation.
See <http://clisp.org/impnotes/debugger.html#describe>
for details.
* FFI modules can now take advantage of autoconf feature detection.
See <http://clisp.org/impnotes/dffi.html#ffi-guard> for details.
* New FFI macro FFI:DEF-C-CONST.
See <http://clisp.org/impnotes/dffi.html#def-c-const> for details.
* New charset BASE64 encodes arbitrary byte sequences with strings of
printable ASCII characters (4 characters per 3 bytes).
See <http://clisp.org/impnotes/encoding.html#base64> for details.
* New module readline offers some advanced readline and history features.
It is a BASE module and is available when both FFI and readline are present.
* SOCKET:SOCKET-SERVICE-PORT is now deprecated in favor of OS:SERVICE.
See <http://clisp.org/impnotes/syscalls.html#service> for details.
* New SETF-able functions POSIX:GETUID, POSIX:GETGID, POSIX:GETEUID,
POSIX:GETEGID.
New functions POSIX:GROUP-INFO and POSIX:STRING-TIME.
Function POSIX:USER-DATA is renamed to POSIX:USER-INFO.
See <http://clisp.org/impnotes/syscalls.html> for details.
* New NEW-CLX demo: koch.lisp draws fractal snowflakes.
Implemented XLIB:SET-MODIFIER-MAPPING, XLIB:KEYSYM->KEYCODES,
XLIB:ACCESS-HOSTS, XLIB:ADD-ACCESS-HOST, XLIB:REMOVE-ACCESS-HOST,
XLIB:CHANGE-KEYBOARD-CONTROL, XLIB:CHANGE-KEYBOARD-MAPPING,
XLIB:KEYBOARD-MAPPING, XLIB:KEYSYM-NAME, XLIB:KEYCODE->CHARACTER,
XLIB:SHAPE-EXTENTS, XLIB:SHAPE-RECTANGLES, XLIB:DEFAULT-KEYSYM-INDEX.
Use MAP instead of ELT for sequence access in NEW-CLX.
* ANSI CL compliance issues:
+ DEFPACKAGE options :SHADOWING-IMPORT-FROM, :USE, :IMPORT-FROM
accept package designators, not just package names.
+ ENCODE-UNIVERSAL-TIME is now the perfect inverse for DECODE-UNIVERSAL-TIME.
* The command line option -v now affects *LOAD-ECHO* also.
See <http://clisp.org/impnotes/clisp.html#opt-verbose> for details.
* When a CLISP process is killed, clean-up is always executed.
* DEFCLASS now permits user-defined :ALLOCATION arguments.
* Fixed (FUNCTION-LAMBDA-EXPRESSION #'(SETF FOO)) on compiled functions.
* Fixed re-exporting symbols from POSIX to EXT.
* Fixed module rawsock on platforms with non-trivial struct sockaddr layout.
Functions that take a BUFFER argument, also take :START and :END arguments.
Renamed RAWSOCK:LISTEN to RAWSOCK:SOCK-LISTEN to avoid a conflict with CL.
New functions RAWSOCK:PROTOCOL, RAWSOCK:NETWORK, RAWSOCK:GETADDRINFO,
RAWSOCK:GETNAMEINFO.
See <http://clisp.org/impnotes/rawsock.html> for details.
* Fixed module postgresql logging behavior.

2.35 (2005-08-29)
=================
User visible changes
--------------------
* SOCKET:SOCKET-STREAM-SHUTDOWN does not call CLOSE anymore,
just shutdown(2) - as it has always been documented.
It now also works on raw sockets, thus RAWSOCK:SHUTDOWN has been removed.
See <http://clisp.org/impnotes/socket.html#sost-shut> and
<http://clisp.org/impnotes/rawsock.html> for details.
* When the command line option -E receives an invalid encoding,
ISO-8859-1 is used instead. [It was ASCII (for *FOREIGN-ENCODING*) or
UTF-8 (for all other encodings) before.]
Rationale: this is a 1:1 that corresponds to CLISP CODE-CHAR/CHAR-CODE
and avoids spurious errors in DIRECTORY on startup.
* New function EXT:COMPILED-FILE-P - checks whether the file is a
CLISP-compiled file with a compatible bytecode format.
See <http://clisp.org/impnotes/compiled-file-p.html> for details.
* New functions EXT:CHAR-INVERTCASE, EXT:STRING-INVERTCASE and
EXT:NSTRING-INVERTCASE invert case of characters and strings.
See <http://clisp.org/impnotes/char-case.html#char-invertcase> and
<http://clisp.org/impnotes/string-misc.html#string-invertcase> for details.
* New function POSIX:STREAM-OPTIONS calls fcntl(2).
See <http://clisp.org/impnotes/syscalls.html#fcntl> for details.
* Explicitly close all possible file descriptors before exec().
* Danish translations of the user interface messages have been added.
Thanks to Dennis Decker Jensen <dennisdjensen@tiscali.dk>.
2.34 (2005-07-20)

Important notes
---------------
* All .fas files generated by previous CLISP versions are invalid and
must be recompiled. This is caused by the addition of MOP, the DEFSETF
fixes, and the TRANSLATE-PATHNAME and MAKE-HASH-TABLE enhancements.
Set CUSTOM:*LOAD-OBSOLETE-ACTION* to :COMPILE to automate this.
See <http://clisp.org/impnotes/loadfile.html> for details.
* The name of the Run-Control file has changed from '_clisprc' to
'.clisprc' on all platforms.
If you are using woe32, please rename your Run-Control file.
* Modules i18n, regexp, and syscalls are now present even in the base
linking set. Do not pass, e.g., "--with-module=regexp" to configure.

* You can create formatting streams of class EXT:FILL-STREAM.
See <http://clisp.org/impnotes/fill-stream.html> for details.
* SUBTYPEP can determine subtype relationship and type equivalence much better
than it could before.
* When *PRINT-READABLY* is true, symbols are now printed with package marker
and vertical bars.
* ANSI CL compliance issues:
+ Issue <DECLARATION-SCOPE:NO-HOISTING> is implemented: The scope of
declarations that do not apply to bindings, such as free SPECIAL, NOTINLINE
or OPTIMIZE declarations, includes only the body forms and no longer
includes the initforms of the LAMBDA/LET/LET*/MULTIPLE-VALUE-BIND bindings.
+ Vectors of element type NIL are now strings in all aspects. But the type
BASE-STRING does _not_ include vectors of element type NIL.
+ TYPE-OF now returns STANDARD-CHAR instead of CHARACTER when possible.
+ The type COMPILED-FUNCTION no longer encompasses generic functions.
+ TYPE-OF now returns COMPILED-FUNCTION or STANDARD-GENERIC-FUNCTION instead
of FUNCTION when possible.
+ The space character is printed as "#\ " if CUSTOM:*PRINT-SPACE-CHAR-ANSI*
is true.
+ The #<PACKAGE KEYWORD> no longer has the nickname "". The syntax :FOO for
keywords still works, but is now special cased in the reader.
+ Class redefinition with DEFCLASS no longer modifies the previous class if
it doesn't have a "proper name".
+ Class redefinition with DEFCLASS removes accessor methods that have been
installed through the previous DEFCLASS definition of the same class.
+ Generic function redefinition with DEFGENERIC removes methods that have
been installed through the previous DEFGENERIC definition of the same
function.
+ The set of qualifiers allowed for methods that are combined with a method
combination defined through the short form of DEFINE-METHOD-COMBINATION
now includes the name of the method combination instead of the operator.
+ FIND-METHOD now gives an error if the list of specializers has a wrong
length.
+ ARRAY-TOTAL-SIZE-LIMIT, ARRAY-DIMENSION-LIMIT, ARRAY-RANK-LIMIT are now
fixnums.
+ SHORT-FLOATs whose absolute value is an integer in the range between 10^5
and 10^7 are now printed with full precision.
+ Operations combining rational and floating-point numbers now return a
floating-point result if CUSTOM:*FLOATING-POINT-RATIONAL-CONTAGION-ANSI*
is true. When the mathematical result in a situation is rational, a
warning is issued if CUSTOM:*WARN-ON-FLOATING-POINT-RATIONAL-CONTAGION* is
true.
+ Class redefinition with DEFCLASS now updates existing instances as
specified.
+ An ABORT restart is now always installed.
+ UPDATE-INSTANCE-FOR-DIFFERENT-CLASS does the required argument checking.
+ Passing invalid initialization arguments to MAKE-INSTANCE and similar
now generates a PROGRAM-ERROR instead of just an ERROR.
+ Documentation strings are now attached to class objects, not just to
their name.
+ Arrays with total array size 0 are printed in a lossy way if
CUSTOM:*PRINT-EMPTY-ARRAYS-ANSI* is true and *PRINT-READABLY* is false.
+ Allow () to match NIL in destructuring lambda lists.
+ Documentation strings at a place where only declarations and forms are
allowed now give a warning, not an error.
+ LAST, BUTLAST and NBUTLAST check their list argument for circularity.
+ Different LOAD-TIME-VALUE forms that are EQUAL but not EQ are no longer
coalesced by COMPILE-FILE.
+ DEFSETF lambda-lists now support &ENVIRONMENT.
+ DEFSETF lambda-lists are no longer destructuring lambda-lists.
+ NAMESTRING no longer accepts an optional second argument.
+ SETF of VALUES now uses only the first value of each subform.
+ SPECIAL declarations of variables are now correctly respected inside
macro expanders defined through MACROLET within the declaration's scope.
+ (EXPORT NIL), (UNEXPORT NIL), (IMPORT NIL), (SHADOWING-IMPORT NIL),
(SHADOW NIL) are now nops.
+ An attempt to create a condition from an invalid condition designator now
always results in a TYPE-ERROR being signalled.
+ The reader's errors are now of type READER-ERROR when they should be.
+ READ-DELIMITED-LIST now returns NIL when *READ-SUPPRESS* is true.
+ Printing of multidimensional arrays now respects *PRINT-LEVEL*.
+ As required by 19.2.3, *DEFAULT-PATHNAME-DEFAULTS* is merged into
pathnames before accessing the file system.
+ LOGICAL-PATHNAME now gives an error if the argument string does not
contain a host specification.
+ The PRINT-UNREADABLE macro prints extraneous spaces if
CUSTOM:*PRINT-UNREADABLE-ANSI* is true.
+ In the #n= and #n# reader syntax, the integer n may now be larger than
7 digits.
+ IN-PACKAGE forms with constant arguments are no longer executed by the
compiler if they occur in a non-null lexical environment.
+ COMPILE-FILE now always returns the TRUENAME of its output file.
+ GET-SETF-EXPANSION now accepts NIL as the environment argument to
mean null lexical environment

* Global error handlers can now be installed and removed using
EXT:SET-GLOBAL-HANDLER, EXT:WITHOUT-GLOBAL-HANDLERS,
and -on-error command line option.
See <http://clisp.org/impnotes/restarts.html#global-handler> and
<http://clisp.org/impnotes/clisp.html#opt-on-error> for details.
* TRANSLATE-PATHNAME and TRANSLATE-LOGICAL-PATHNAME accept a new keyword
argument :ABSOLUTE which makes them convert their return values to
absolute pathnames.
See <http://clisp.org/impnotes/filename-misc.html#translate-pathname> and
<http://clisp.org/impnotes/filename-misc.html#translate-logpath> for details.
* New function EXT:ABSOLUTE-PATHNAME.
See <http://clisp.org/impnotes/filename-misc.html#absolute-pathname> for details.
* New function EXT:ELASTIC-NEWLINE and new FORMAT directive "~.".
See <http://clisp.org/impnotes/elastic-newline.html>
and <http://clisp.org/impnotes/print-formatted.html#format-dot> for details.
Through this function, CLISP no longer produces spurious blank lines when
a program uses the convention of printing a #\Newline before each line.
* TRACE has a new option :MAX-DEPTH, that is useful to avoid infinite
recursions in the tracer.
See <http://clisp.org/impnotes/debugger.html#trace> for details.
* The function LENGTH and a few other sequence functions now signal a
TYPE-ERROR when a circular list has been given as argument.
* Function UPGRADED-COMPLEX-PART-TYPE is now as precise as possible.
See <http://clisp.org/impnotes/num-concepts.html#ucpt> for details.
* In non-interactive batch mode, *ERROR-OUTPUT* now uses the system's
standard error stream, instead of the standard output stream.
* The macros MUFFLE-CERRORS, APPEASE-CERRORS and EXIT-ON-ERROR now treat
CONTINUE restarts which require interactive user intervention like other
restarts. Only non-interactive CONTINUE restarts are silently invoked.
* LOAD :OBSOLETE-ACTION can now also be :COMPILE to automatically
recompile the obsolete *.fas file.
LOAD can now ignore erroneous forms using SKIP and STOP restarts.
See <http://clisp.org/impnotes/loadfile.html> for details.
* References from within macros defined through MACROLET to variables or
functions defined in the lexical environment outside the MACROLET form
now signal an error. Previously, this resulted in undefined behavior.
* The FFI recognizes the c-type declaration (FFI:C-POINTER <c-type>) to
handle references without conversion to/from Lisp structures.
See <http://clisp.org/impnotes/dffi.html#c-pointer> for details.

The warning "*FOREIGN-ENCODING*: reset to ASCII" at startup is gone.
* New FFI constructor functions FFI:FOREIGN-VARIABLE and FFI:FOREIGN-FUNCTION,
more operators are now exported (FFI:FOREIGN-VALUE, FFI:PARSE-C-TYPE).
See <http://clisp.org/impnotes/dffi.html#dffi-make-var>
and <http://clisp.org/impnotes/dffi.html#dffi-make-func> for details.
* FFI macro FFI:C-LINES can now be used to fine-tune
initialization and finalization.
See <http://clisp.org/impnotes/dffi.html#c-lines> for details.
* New FFI function FFI:CLOSE-FOREIGN-LIBRARY can be used to unload a library.
See <http://clisp.org/impnotes/dffi.html#dffi-close-lib> for details.
* New FFI low-level accessor FFI:MEMORY-AS.
See <http://clisp.org/impnotes/dffi.html#memory-as> for details.
* Foreign functions and variables can now be documented using the
:DOCUMENTATION option to FFI:DEF-CALL-OUT and FFI:DEF-C-VAR.
* Buffered streams now are suitable for interactive streams. It is no longer
necessary to use :BUFFERED NIL to avoid blocking in various situations.
* Function EXT:READ-BYTE-SEQUENCE takes a new keyword argument :INTERACTIVE.
See <http://clisp.org/impnotes/bulk-io.html#rd-by-seq> for details.
* Methods on GRAY:STREAM-READ-BYTE-SEQUENCE and GRAY:STREAM-WRITE-BYTE-SEQUENCE
now need to accept a second optional argument.
* The possible values of the :WEAK argument of MAKE-HASH-TABLE are changed:
Use :KEY-AND-VALUE instead of :EITHER, :KEY-OR-VALUE instead of :BOTH now.
* The :LIBRARY option argument to EXT:DEF-CALL-OUT and EXT:DEF-C-VAR is now
evaluated (i.e., it can now be a variable) and may take a value of
:DEFAULT and :NEXT in addition to being a string as before.
See <http://clisp.org/impnotes/dffi.html#def-c-var> and
<http://clisp.org/impnotes/dffi.html#def-call-out> for details.
* New user variable CUSTOM:*PRINT-SYMBOL-PACKAGE-PREFIX-SHORTEST*
allows using the shortest package (nick)name as the symbol prefix.
See <http://clisp.org/impnotes/sym-pack-prefix.html#pr-sym-pack-prefix>
for details.
* The user commands can now be extended using CUSTOM:*USER-COMMANDS*.
See <http://clisp.org/impnotes/repl.html#user-commands> for details.
* Initialization and finalization of the CLISP process can now be
augmented with CUSTOM:*INIT-HOOKS* and CUSTOM:*FINI-HOOKS*.
See <http://clisp.org/impnotes/custom-init-fini.html#init-hooks> and
<http://clisp.org/impnotes/custom-init-fini.html#fini-hooks> for details.
* SET functions (like UNION et al) are now much faster on large lists.
* The second, optional argument of EXT:SPECIAL-VARIABLE-P can no longer be T;
please use (THE-ENVIRONMENT) instead.
* New function EXT:FEATUREP - the run-time version of read-time #+/#-.
See <http://clisp.org/impnotes/featurep.html> for details.
* Bug fixes:
+ The interpreter no longer executes the body of (EVAL-WHEN (COMPILE) ...)
forms.
+ Fixes to internationalized error messages.
+ When an interpreted INITIALIZE-INSTANCE method uses CALL-NEXT-METHOD with
a modified argument list, MAKE-INSTANCE could in some cases initialize
the new object three times instead of just once.
+ Fixed a compiler bug that could lead to incorrect code when a LAMBDA
with SPECIAL-declared optional variables was compiled inline and the
initforms of the optional variables depended on the values of the previous
optional variables.
+ Passing a package as second argument of RENAME-PACKAGE led to an
unjustified error.
+ Passing a displaced vector as argument to REVERSE could lead to an
unjustified error.
+ FRESH-LINE did not work in some situations.
+ Fixed ATANH on complex numbers.
+ The macros EXT:LETF and EXT:LETF* now work correctly on symbol-macros.
+ Fixed a spurious crash of MULTIPLE-VALUE-SETQ in interpreted code.

characters in the range #\U000E0000..#\U000E007F on a stream with an
encoding other than UTF-8.
+ An invalid bignum could be returned by GET-INTERNAL-RUN-TIME on 64-bit
platforms.
+ Third party code walkers can now handle HANDLER-BIND et al.
* Woe32 distribution now comes with a binary driver clisp.exe.
Do not copy it anywhere - create a shortcut to it instead!
Use install.bat to automate shortcut creation.
* (SOFTWARE-TYPE) now returns memory model information,
valuable in bug reports.

2.33 (2004-03-17)
=================
Important notes
---------------
* All .fas files generated by previous CLISP versions are invalid and
must be recompiled. Use CUSTOM:*LOAD-OBSOLETE-ACTION* to automate this.
See <http://clisp.org/impnotes/loadfile.html> for details.
User visible changes
--------------------
* NO-APPLICABLE-METHOD, NO-PRIMARY-METHOD and NO-NEXT-METHOD now signal
METHOD-CALL-ERROR or METHOD-CALL-TYPE-ERROR.
See <http://clisp.org/impnotes/std-meth-combo.html#meth-call-err> for details.

Gray streams; FILE-POSITION now works with streams other than FILE-STREAMs.
See <http://clisp.org/impnotes/gray.html> for details.
* DEFINE-METHOD-COMBINATION and friends are now implemented.
Thanks to James Anderson <james.anderson@setf.de>.

2.32 (2003-12-29)
=================
User visible changes
--------------------
* WRITE-BYTE-SEQUENCE now accepts :NO-HANG keyword argument.
Thanks to Don Cohen <don-sourceforge@isis.cs3-inc.com>.
* Support files larger than 2 GB or 4 GB on platforms with LFS
(Large File Support).

makes Perl Compatible Regular Expressions available in CLISP.
See <http://clisp.org/impnotes/pcre.html> for details.
* Module syscalls now exports function POSIX:STAT-VFS.
See <http://clisp.org/impnotes/syscalls.html> for details.
* When the system C library provides a wildcard (fnmatch) implementation,
it is used instead of the GNU wildcard distributed with CLISP
when the CLISP wildcard module is built.
* Prompt is now fully customizable by the user.
CUSTOM:*PROMPT* is replaced with 5 variables.
See <http://clisp.org/impnotes/prompt.html> for details.
* Readline is now used properly on Cygwin/X11.
* Command line interface: the initial verbosity level is controlled
by the pair of mutually canceling options -q/-v.
See <http://clisp.org/impnotes/clisp.html#opt-verbose> for details.
2.31 (2003-09-01)
=================
Important notes
---------------
* All .fas files generated by previous CLISP versions are invalid and
must be recompiled. This is not as bad as it was before: the invalid
files will be ignored and the sources will be loaded instead of
signaling an error unless you set CUSTOM:*LOAD-OBSOLETE-ACTION*.
See <http://clisp.org/impnotes/loadfile.html> for details.
* All custom-written external modules must be updated to reflect
changes in the C definitions, e.g. many C types were renamed to a
trailing _t (subr_t, object_initdata_t) and LISPFUN takes an
additional side-effect class (seclass) parameter.
User visible changes
--------------------
* Added a new module - "fastcgi": an interface to the FastCGI
Web server CGI-compatible protocol (see http://www.fastcgi.com/)
Thanks to John K. Hinsdale <hin@alma.com>.
See <http://clisp.org/impnotes/fastcgi.html> for details.
* External modules now work on win32 (when used with cygwin or mingw).
See <http://clisp.org/impnotes/modules.html#mod-win32> for details.
* DIRKEY is now a standard module: use `--with-module=dirkey'
instead of `--with-dir-key' when configuring.
See <http://clisp.org/impnotes/dir-key.html> for details.
* SYSCALLS is now a standard module: use `--with-module=syscalls
instead of `--with-export-syscalls' when configuring.
See <http://clisp.org/impnotes/syscalls.html> for details.
* New module netica interfaces to <http://norsys.com/netica_c_api.htm>
and allows working with Bayesian belief networks and influence diagrams.
See <http://clisp.org/impnotes/netica.html> for details.
* READ-BYTE-SEQUENCE now accepts :NO-HANG keyword argument.
* LOAD now takes an additional keyword argument :OBSOLETE-ACTION which
specifies what to do with the obsolete .fas files.
See <http://clisp.org/impnotes/loadfile.html> for details.
* EXT:SPECIAL-VARIABLE-P now accepts a second optional ENVIRONMENT argument.
See <http://clisp.org/impnotes/declarations.html#spe-var-p> for details.
* You can now set socket options using new function SOCKET:SOCKET-OPTIONS.
See <http://clisp.org/impnotes/socket.html#so-opt> for details.
Suggested by Dave Richards <dave@synergy.org>.
* SOCKET:SOCKET-STATUS now distinguishes between :EOF and :INPUT.
Also, it does not have to cons up a fresh list even for multiple streams.
See <http://clisp.org/impnotes/socket.html#so-status> for details.
* CLISP character set now uses Unicode 3.2.
See <http://clisp.org/impnotes/characters.html> for details.
* DIRECTORY now accepts a new keyword argument :IF-DOES-NOT-EXIST which
controls treatment of links pointing to non-existent files.
It defaults to :DISCARD which is fully backward compatible.
See <http://clisp.org/impnotes/dir-func.html#dir> for details.
* DELETE-FILE no longer calls TRUENAME on its argument, which enables
you to delete symbolic links. This is an incompatible change.
You can get the old behavior by doing (DELETE-FILE (TRUENAME path)).
See <http://clisp.org/impnotes/file-func.html#del-file> for details.
* DRIBBLE now works by redefining *TERMINAL-IO* instead of a host of
i/o variables. This allows DRIBBLE to be started and stopped in
different break loops.
See <http://clisp.org/impnotes/debugger.html#dribble> for details.
* Weak hash tables can now remove key/value pairs when either or both
are garbage collected.
See <http://clisp.org/impnotes/make-hash.html> for details.
* You can use (SETF WEAK-POINTER-VALUE) to change the object to which
the given weak pointer point to.
See <http://clisp.org/impnotes/weak.html> for details.
* New macro EXT:DEFINE-HASH-TABLE-TEST allows user-defined hash table tests.
See <http://clisp.org/impnotes/defhash.html> for details.
* ANSI CL compliance issues:
+ MAPC, MAPCAR, MAPCAN, MAPL, MAPLIST, MAPCON now require their list
arguments to be proper lists;
+ TAILP uses EQL, not EQ, to compare the sublists;
+ LOOP was fixed in many many ways, including
- using ATOM as the end test for ON iteration,
- returning the SUMs (and alike) of the specified type (if any),
- checking that the THEREIS return value is not shadowed,
- treating keyword IT in an inappropriate place as a variable,
- signaling SOURCE-PROGRAM-ERROR errors at macroexpansion time,
- not requiring the package argument for symbol iteration,
- making local variables accessible in the INITIALLY clauses,
- initializing accumulation variables after iteration variables
to avoid shadowing,
- using forward consing for APPEND/NCONC because REVAPPEND/NRECONC
drop the last atom in dotted lists,
- checking for duplicate variables in iteration clauses;
+ DOCUMENTATION is now a generic function;
+ implemented CHANGE-CLASS, UPDATE-INSTANCE-FOR-DIFFERENT-CLASS,
MAKE-INSTANCES-OBSOLETE, UPDATE-INSTANCE-FOR-REDEFINED-CLASS, and
ENSURE-GENERIC-FUNCTION;
+ DEFCLASS no longer requires that direct superclasses already exist;
+ sequence functions (MAP, LENGTH and such) no longer accept dotted lists
and treat NULL as LIST of length 0 and CONS as LIST of positive length;
+ COERCE accepts CLOS class object as a type-spec (second argument) and
coerces FLOAT to COMPLEX by returning a COMPLEX number;
+ DEFSTRUCT uses the slot name as is for the accessor when :CONC-NAME
is NIL (i.e., does not intern the name in *PACKAGE*), and does not
bind slot names in the arglist of keyword constructors;
+ MAPCAN and MAPCON now correctly handle functions returning ATOMs;
+ removed macro definition from GENERIC-FUNCTION;
+ APPEND, COPY-ALIST, REVAPPEND, NRECONC, PAIRLIS, GET, GETF,
REMPROP, GET-PROPERTIES no longer accept dotted lists;
+ implemented arrays with ARRAY-ELEMENT-TYPE NIL;
+ implemented ANSI CL Issues <CONDITION-RESTARTS:PERMIT-ASSOCIATION>,
<DEBUGGER-HOOK-VS-BREAK:CLARIFY>, <DOCUMENTATION-FUNCTION-BUGS:FIX>,
<EXTERNAL-FORMAT-FOR-EVERY-FILE-CONNECTION:MINIMUM>,
<IMPORT-SETF-SYMBOL-PACKAGE>, <SETF-FIND-CLASS:ALLOW-NIL>,
<SUBTYPEP-ENVIRONMENT:ADD-ARG>, <THE-VALUES:RETURN-NUMBER-RECEIVED>,
<ADJUST-ARRAY-NOT-ADJUSTABLE:IMPLICIT-COPY>;
+ EQUALP on HASH-TABLEs now correctly descends the structure;
+ macro definitions now respect the lexical environment;
+ more thorough lambda list matching check;
+ DEFINE-CONDITION now return the condition name;
+ a character is now accepted as a package designator.
Thanks to Paul F. Dietz <dietz@dls.net> and his ANSI compliance
suite, which helped detect some of these deficiencies.
* FUNCTION-LAMBDA-EXPRESSION now always returns the correct function name.
See <http://clisp.org/impnotes/misc-data.html#fle> for details.
* CONSTANTP now detects many more constant forms.
See <http://clisp.org/impnotes/declarations.html#constantp> for details.
* The code walker has now a public interface: EXT:EXPAND-FORM.
See <http://clisp.org/impnotes/code-walk.html> for details.
* Renamed macro SPACE to EXT:TIMES because SPACE is an ANSI Common Lisp
symbol without a macro definition.
See <http://clisp.org/impnotes/debugger.html#time> for details.
* New function EXT:XOR checks that exactly one of its arguments is non-NIL.
See <http://clisp.org/impnotes/xor.html> for details.
* New function EXT:MAKE-STREAM creates a stream out of a file descriptor
and facilitates CGI scripting.
See <http://clisp.org/impnotes/make-stream.html> and
<http://clisp.org/impnotes/stream-eltype.html#bin-stdio> for details.
* New function EXT:MODULE-INFO provides information about the CLISP
modules that comprise the running image.
See <http://clisp.org/impnotes/modules.html#modinfo> for details.
* New generic function CLOS:CLASS-PROTOTYPE from MOP.
See <http://clisp.org/impnotes/mop-classes.html#class-prototype> for details.
* New generic functions CLOS:CLASS-FINALIZED-P and
CLOS:FINALIZE-INHERITANCE from MOP.
See <http://clisp.org/impnotes/def-class.html> for details.
* New FFI functionality:
+ functions FFI:FOREIGN-ALLOCATE and FFI:FOREIGN-FREE and macros
FFI:ALLOCATE-DEEP and FFI:ALLOCATE-SHALLOW permit heap allocation;
see <http://clisp.org/impnotes/dffi.html#foreign-heap> for details;
+ functions FFI:FOREIGN-ADDRESS-UNSIGNED and FFI:UNSIGNED-FOREIGN-ADDRESS,
see <http://clisp.org/impnotes/dffi.html#faddr-u> for details;
+ function FFI:FOREIGN-ADDRESS,
see <http://clisp.org/impnotes/dffi.html#faddr> for details;
+ functions FFI:FOREIGN-POINTER and (SETF FFI:FOREIGN-POINTER),
see <http://clisp.org/impnotes/dffi.html#fptr> for details;
+ macros FFI:C-VAR-ADDRESS, FFI:C-VAR-OBJECT and FFI:OFFSET,
see <http://clisp.org/impnotes/dffi.html#offset> and
<http://clisp.org/impnotes/dffi.html#c-var-addr>;
+ function (SETF FFI:VALIDP) invalidates foreign objects
see <http://clisp.org/impnotes/dffi.html#validp> for details;
+ macros FFI:WITH-FOREIGN-STRING, and macro FFI:WITH-C-PLACE,
see <http://clisp.org/impnotes/dffi.html#foreign-stack-string> and
<http://clisp.org/impnotes/dffi.html#with-c-place>.
Thanks to Jörg Höhle <hoehle@users.sourceforge.net>.
+ FFI:DEF-CALL-OUT and FFI:DEF-C-VAR now accept a :LIBRARY option which
allows you to specify the dynamic library which contains the object.
See <http://clisp.org/impnotes/dffi.html#def-call-out> and
<http://clisp.org/impnotes/dffi.html#def-c-var>.
+ Introduced a bit of polymorphism: FFI:C-POINTER can be NIL and will
be treated as NULL; NULL return value of type FFI:C-POINTER is
returned as NIL.
See <http://clisp.org/impnotes/dffi.html#c-pointer>.
+ You can now map between numeric and symbolic C enum values using
functions FFI:ENUM-FROM-VALUE and FFI:ENUM-TO-VALUE.
See <http://clisp.org/impnotes/dffi.html#def-c-enum>.
* FFI does not output extern variable and function declarations unless
you set FFI:*OUTPUT-C-VARIABLES* and/or FFI:*OUTPUT-C-FUNCTIONS* to T.
Please use FFI:C-LINES to include the appropriate headers instead.
See <http://clisp.org/impnotes/dffi.html#ffi-extern-output> for details.
* Regexp module functions now support more options, e.g., :EXTENDED to
use extended regular expressions, and do not rely on FFI.
In particular, REGEXP:REGEXP-COMPILE now accepts keyword and not
optional arguments (this is not backwards compatible).
When the system library provides a regexp implementation,
it is used instead of the GNU regexp distributed with CLISP.
The number of subexpressions is now unlimited (the limit was 10).
See <http://clisp.org/impnotes/regexp-mod.html> for details.
* Unified modules postgresql632 and postgresql642 into postgresql.
The postgresql module works with PostgreSQL 6 and 7 now.
* Removed obsolete module linuxlibc5 and renamed module linuxlibc6 to glibc.
* New module: bindings/win32 (highly incomplete, patches are welcome).
* The BACKQUOTE reader has been reimplemented from scratch by
Kaz Kylheku <kaz@ashi.footprints.net>.
* New function EXT:MAKE-XTERM-IO-STREAM creates an input-output stream
that uses a separate X terminal. Unix platforms only.
See <http://clisp.org/impnotes/syscalls.html#mk-xterm-io> for details.
* Fixed a bug in PEEK-CHAR with non-NIL peek-type on ECHO-STREAMS.
* Fixed a bug in FILE-POSITION after UNREAD-CHAR (or PEEK-CHAR).
* Fixed a bug in bit operations on multi-dimensional arrays.
* CLISP/MIT-CLX now compiles CLOCC CLUE/CLIO.
See <http://clocc.sourceforge.net/clocc/src/gui/clue/> and
<http://clisp.org/impnotes/modules.html#incmod-gui>.
* CLISP/NEW-CLX on win32 with Cygwin X server compiles garnet.
See <https://sourceforge.net/p/clisp/mailman/message/12561966/>.
* Command line interface: allow multiple -x options.
New options -repl <http://clisp.org/impnotes/clisp.html#opt-repl>
and -v (--verbose) <http://clisp.org/impnotes/clisp.html#opt-verbose>.
2.30 (2002-09-15)
=================
User visible changes
--------------------
* CLISP does not come with GNU libiconv anymore. The most important
encodings are built-in anyway, and CLISP can use the GNU libc 2.2
iconv and a GNU libiconv when it is independently installed.
* CLISP does not come with GNU gettext anymore. This is a separate
package and should be installed separately, if you wish to use i18n.
* CLISP does not come with GNU readline anymore, because, starting with
version 4.3, readline supports multibyte characters out of the box.
* CLISP does not come with GNU libsigsegv anymore. This means that in
certain cases of infinite recursion, the C stack overflow will not be
properly detected and will result in a segfault instead of an error.
You are urged to download and install GNU libsigsegv from
<ftp://ftp.gnu.org/pub/gnu/libsigsegv/> or
<http://sourceforge.net/projects/libsigsegv/>
before configuring CLISP.
* Strings can now hold UCS-4 characters, instead of only UCS-2 characters.
CHAR-CODE-LIMIT increased from 65536 to 1114112.
* Added a new module - "oracle": an interface to the Oracle ODBMS.
Thanks to John K. Hinsdale <hin@alma.com>.
* New user variable CUSTOM:*PARSE-NAMESTRING-DOT-FILE* controls
how the file names starting with a dot are parsed.
By default, it is set to :NAME in config.lisp,
so #P".clisprc" is now #S(PATHNAME :NAME ".clisprc").
To get the old result of #S(PATHNAME :TYPE "clisprc"),
set this variable to :TYPE.
This is an incompatible change.
See <http://clisp.org/impnotes/path-components.html#name-type-split> for details.
* New user variable CUSTOM:*TRACE-INDENT* controls TRACE output indentation.
See <http://clisp.org/impnotes/debugger.html#trace> for details.

* SAVEINITMEM now accepts :START-PACKAGE, :VERBOSE, and :LOCKED-PACKAGES
keyword arguments.
See <http://clisp.org/impnotes/image.html> for details.
* You can now shutdown a socket for input or output separately
using SOCKET:SOCKET-STREAM-SHUTDOWN.
See <http://clisp.org/impnotes/socket.html#sost-shut> for details.
* CUSTOM:*SOURCE-FILE-TYPES* and CUSTOM:*COMPILED-FILE-TYPES*
now contain strings, not pathnames.
See <http://clisp.org/impnotes/loadfile.html> for details.
* EXT:GETENV now returns all of the OS environment as an alist
when its argument is omitted or NIL.
See <http://clisp.org/impnotes/getenv.html> for details.
* When configured with --with-export-syscalls,
several new functions are available:
POSIX:STREAM-LOCK provides an interface to flock(2);
POSIX:COPY-FILE provides an interface to link(2)/symlink(2)/rename(2),
(in addition to the usual file copy);
POSIX:DUPLICATE-HANDLE provides an interface to dup(2)/dup2(2).
Thanks to Marco Baringer for COPY-FILE and DUPLICATE-HANDLE.
See <http://clisp.org/impnotes/syscalls.html> for details.
* You can now control the CLISP exit code better by passing a
non-negative integer to EXT:EXIT.
See <http://clisp.org/impnotes/quit.html> for details.

allocating C data on the stack.
See <http://clisp.org/impnotes/dffi.html#foreign-stack> for details.
* Russian translations of the user interface messages have been added.
Thanks to Arseny Slobodjuck <ampy@ich.dvo.ru>.
* When built with readline, CLISP will DESCRIBE the current function
when you hit TAB after a #\Space.
* MAKE-ENCODING now checks whether the iconv charset is valid, and
signals an error if it is invalid unless given the :IF-DOES-NOT-EXIST
NIL argument.
* New debugger command Quit (:q) aborts to the top-level read-eval-print
loop immediately, saving you typing :a several times.
* When CUSTOM:*PARSE-NAMESTRING-ANSI* is non-NIL, do not accept symbols
as pathname designators.
See <http://clisp.org/impnotes/filename-misc.html#parsename> for details.
* COMPILE-FILE no longer clobbers an existing *.c file when the Lisp
file being compiled does not contain any FFI forms.
See <http://clisp.org/impnotes/compilefile.html> for details.
* Type COMPLEX now correctly uses UPGRADED-COMPLEX-PART-TYPE.
* Improved accuracy of some transcendental functions, e.g., now
(EXPT -5.0 2.0) return #C(25.0 0.0).
* Fixed a bug: Conversion from bytes to string did not work for the encoding
(MAKE-ENCODING :CHARSET CHARSET:UNICODE-32-LITTLE-ENDIAN
:INPUT-ERROR-ACTION :IGNORE).
* Fixed a bug in compiling duplicate keyword arguments.
* Fixed the (destructuring-bind (&key (x x)) ...) bug.
* Wide-mode -W backward compatibility option is now gone
(defunct since 1998-09-09). This permits colons in memory image file
names (necessary on Cygwin).
* CLISP on Cygwin now understands native pathnames like "c:/gnu/clisp/"
by translating them internally to "/cygdrive/c/gnu/clisp/".
CLISP on Win32 now understands Cygwin pathnames like "/cygdrive/c/gnu/clisp/"
by translating them internally to "c:/gnu/clisp/".
You can disable this by setting CUSTOM:*DEVICE-PREFIX* to NIL.
See <http://clisp.org/impnotes/filenames.html#device-prefix> for details.
* Readline is now used properly on Cygwin.
* DIR-KEY now works on Cygwin.

2.28 (2002-03-03)
=================
Important notes
---------------
* All .fas files generated by previous CLISP versions
are invalid and must be recompiled.
User visible changes
--------------------
* ANSI CL functions MAKE-LOAD-FORM and MAKE-LOAD-FORM-SAVING-SLOTS
are implemented.
* ANSI CL pretty printer <http://clhs.lisp.se/Body/22_b.htm> is implemented.
In particular,

are implemented.
See <http://clisp.org/impnotes/clpp.html> for details.
* The functions WRITE and WRITE-TO-STRING now accept :LINES, :MISER-WIDTH
and :PRINT-PPRINT-DISPATCH keyword arguments.
This change requires recompilation of all .fas files.
* Weak hash-tables are now supported.
See <http://clisp.org/impnotes/make-hash.html> for details.

but not a whole number of bytes.
2.26 (2001-05-23)
=================
Important notes
---------------
* The CLISP extensions have been moved from the CLtL1 package LISP to
separate packages.
If you rely on any of the CLISP extensions, you will need to make
your packages use package EXT, which re-exports all exported symbols
from all extension packages.
* All .fas files generated by previous CLISP versions
are invalid and must be recompiled.
User visible changes
--------------------
* "LISP" is now a nickname of the ANSI CL package COMMON-LISP.
"USER" is now a nickname of the ANSI CL package COMMON-LISP-USER.
Support for CLtL1 has thus been removed.
For the benefit of package developers, *FEATURES* now contains :LISP=CL.
* The *FEATURES* list now contains :ANSI-CL instead of :CLTL2 even when
running without '-ansi' ANSI compatibility mode.
* ANSI CL compliance: function UPGRADED-COMPLEX-PART-TYPE implemented.
* ANSI CL compliance: macro HANDLER-BIND invokes all handlers
for the condition, not just the first one.
* ANSI CL compliance: CHAR does not check for FILL-POINTER, while ELT does.
* ANSI CL compliance: FUNCTION-KEYWORDS returns 2 values.
* ANSI CL compliance: COMPILED-FUNCTION is a subtype of FUNCTION.
* ANSI CL compliance: implemented compiler macros.
* Conforming to the ANSI CL issue CONSTANTP-ENVIRONMENT:ADD-ARG,

for all functions, not just the inlined built-ins.
2.25.1 (2001-04-06)
===================
User visible changes [this is a bug-fix only release]
--------------------
* ANSI CL compliance: INITIALIZE-INSTANCE accepts &KEY &ALLOW-OTHER-KEYS
arguments.
* Fixed a bug: a single value was sometimes returned by READ-LINE.
* Fixed a bug: re-exporting inherited symbols resulted in them being
reported as both external and inherited by WITH-PACKAGE-ITERATOR.
* Fixed a bug: the full image and other images created with clisp-link
exited on error instead of entering the debugger.
* Fixed a bug: COMPILE-FILE-PATHNAME could return bad results when given a
non-existent INPUT-FILE argument and an OUTPUT-FILE argument with
non-NIL directory part.
* Fixed --without-unicode build.
2.25 (2001-03-15)
=================
Important notes
---------------
* The default extension of Lisp source files for CLISP is now ".lisp" instead
of ".lsp". When both "foo.lisp" and "foo.lsp" exist, (LOAD "foo") will load
"foo.lisp".
* Changed bytecode format. All .fas files generated by previous CLISP versions
are invalid and must be recompiled.
User visible changes
--------------------
* A new version numbering scheme is adopted.
* If an error is signalled by a form supplied with the command-line
option "-x", CLISP now exits with a non-zero status.
* The pretty-printer does not print hanging parenthesis by default now.
*PRINT-RPARS* now defaults to NIL and *PRINT-INDENT-LISTS* to 1, so
that the lists are printed like in CLHS and CLtL.

New generic functions STREAM-READ-BYTE-LOOKAHEAD,
STREAM-READ-BYTE-WILL-HANG-P, STREAM-READ-BYTE-NO-HANG.
* CONCATENATED-STREAM-STREAMS now returns only the remaining streams,
as per ANSI CL spec.
* Implemented ANSI CL function INSPECT,
and a function LISP:CLHS for access of Common Lisp HyperSpec.
* Characters have now the same names as in Unicode 3.0, with space replaced
by underscore.
* ANSI CL compliance: CALL-NEXT-METHOD and NEXT-METHOD-P are now implemented
as local functions, not local macros. It is now possible to call
(APPLY #'CALL-NEXT-METHOD argument-list-of-unknown-length).
* ANSI CL compliance: LOAD has a new keyword argument :EXTERNAL-FORMAT.
* ANSI CL compliance: When an end-of-stream occurs, READ, READ-CHAR, PEEK-CHAR,
READ-CHAR-NO-HANG, READ-LINE, READ-BYTE, READ-INTEGER, READ-FLOAT, called
with arguments eof-error-p = NIL and without eof-value, now return NIL
instead of #<END OF FILE>.
* ANSI CL compliance: When LISP:*PARSE-NAMESTRING-ANSI* is non-NIL,
PARSE-NAMESTRING parses strings with colons as logical pathnames.

* Arguments passed to MAKE-PATHNAME with value NIL are not overridden by
pathname slots in the :DEFAULTS argument any more.
* STREAM-ELEMENT-TYPE of a TWO-WAY-STREAM or an ECHO-STREAM now depends on
the stream's constituents. Previously, it was always (OR CHARACTER INTEGER).
* Fixed a bug: REPLACE signalled an error if the source and destination
sequences were the same and the source and destination ranges did not
overlap.
* Fixed a bug: A garbage collection during the execution of a foreign function
callback caused a crash.
* Fixed a bug: Calling READ-LINE on a stream already positioned at EOF caused
a crash on 64-bit platforms.
* Fixed a bug: For long-floats, (EQL x (- x)) returned true.
* Fixed a bug: OPEN now returns NIL when the filename's directory does not
exist and :IF-DOES-NOT-EXIST NIL was specified. Previously, an error was
signalled except when :DIRECTION was :PROBE.
* Fixed a bug: (subtypep 'fundamental-stream 'stream) returned NIL.
Portability
-----------
* Added support for IA-64 running Linux.
* Added support for BeOS 5. Thanks to Alexis Rivera Rios <ahrivera@yahoo.com>.

=================
User visible changes
--------------------
* New functions READ-FLOAT and WRITE-FLOAT.
* Implemented ANSI CL macro WITH-COMPILATION-UNIT.
* Unicode support: The pretty-printer and FORMAT ~T now handle non-spacing and
double-width Unicode characters correctly. Pretty-printer slows down by 30%.
New functions CHAR-WIDTH, STRING-WIDTH.
* Fixed two bugs in TRANSLATE-PATHNAME: Substitution of "**" did not work.
Substitutions without version into non-logical pathnames crashed.
* Dutch translations of the user interface messages have been added
Thanks to Tijs van Bakel <smoke@casema.net>.
* When configured with --with-export-syscalls, :SYSCALLS is in *FEATURES*
and functions POSIX:RESOLVE-IP-ADDR, POSIX:USER-DATA, POSIX:FILE-STAT,
POSIX:SYSINFO, POSIX:RESOURCE-USAGE-LIMITS,
as well as those libm.so functions which do not have a better
counterpart in ANSI CL are available.
* New supported character sets in package CHARSET: ISO-8859-16, KOI8-U,
KOI8-RU, EUC-JP, SHIFT-JIS, CP932, ISO-2022-JP, ISO-2022-JP-2, ISO-2022-JP-1,

TIS-620, MULELAO-1, CP1133, VISCII, TCVN, UTF-16, UTF-7, MACINTOSH (as an
alias for MAC-ROMAN).
Other modifications
-------------------
* Speed up some sequence functions when operating on vectors: MAKE-SEQUENCE,
CONCATENATE, COPY-SEQ, COERCE, SUBSEQ, REPLACE, FILL, REVERSE, NREVERSE,
REMOVE[-IF[-NOT]] with :START/:END, SUBSTITUTE[-IF[-NOT]] with :START/:END,
SORT.
* Speed up ADJUST-ARRAY.
2.23 (1999-07-22)
=================
User visible changes
--------------------
* Added a new module - "postgresql": interface to the PostgreSQL ODBMS.
* Implemented ANSI CL macro WITH-PACKAGE-ITERATOR.
* Conforming to ANSI CL issue <ALLOCATE-INSTANCE:ADD>: New function
ALLOCATE-INSTANCE.
* Conforming to ANSI CL issue <GENERIC-FLET-POORLY-DESIGNED:DELETE>: The
symbols GENERIC-FLET and GENERIC-LABELS are not exported from the
COMMON-LISP package any more.
* Conforming to ANSI CL issues <KEYWORD-ARGUMENT-NAME-PACKAGE:ANY> and
<MULTIPLE-VALUE-SETQ-ORDER:LIKE-SETF-OF-VALUES>.
* Conforming to ANSI CL Issue <MACRO-FUNCTION-ENVIRONMENT:YES>
MACRO-FUNCTION now takes an optional second argument ENV.
* When CLISP is invoked with an "-a" option, *features* contain :ANSI-CL.
* Weak pointers are implemented. New functions MAKE-WEAK-POINTER,
WEAK-POINTER-P, WEAK-POINTER-VALUE.
* The function OPEN, when creating unbuffered file streams, now supports any
of the following :ELEMENT-TYPEs: CHARACTER and ([UN]SIGNED-BYTE n), where n
is a multiple of 8.
* The functions
MAKE-PIPE-INPUT-STREAM, MAKE-PIPE-OUTPUT-STREAM, MAKE-PIPE-IO-STREAM,
SOCKET-ACCEPT, SOCKET-CONNECT
accept a keyword argument :ELEMENT-TYPE. Possible values are types
equivalent to CHARACTER or (UNSIGNED-BYTE n), (SIGNED-BYTE n), where n is
a positive multiple of 8. Previously these functions returned streams whose
element-type was (OR CHARACTER (UNSIGNED-BYTE 8)).
* STREAM-ELEMENT-TYPE is SETFable. The element type of streams created by the
functions MAKE-PIPE-INPUT-STREAM, MAKE-PIPE-OUTPUT-STREAM,
MAKE-PIPE-IO-STREAM, SOCKET-ACCEPT, SOCKET-CONNECT can be modified, if the
old and the new element type are compatible.
(UNSIGNED-BYTE n) and (SIGNED-BYTE n) are compatible, and CHARACTER is
compatible with ([UN]SIGNED-BYTE 8).
* Character I/O can now be customized via encodings. A stream's external
format is an encoding, and the symbol macros
*DEFAULT-FILE-ENCODING*, *PATHNAME-ENCODING*, *TERMINAL-ENCODING*,
*MISC-ENCODING*, FFI:*FOREIGN-ENCODING*, AFFI:*FOREIGN-ENCODING*
contain user-settable encodings.
Encodings can be obtained through the function MAKE-ENCODING, and as values
of the constants
CHARSET:UCS-2, CHARSET:UNICODE-16, CHARSET:UNICODE-16-BIG-ENDIAN,
CHARSET:UNICODE-16-LITTLE-ENDIAN, CHARSET:UCS-4, CHARSET:UNICODE-32,

CHARSET:WINDOWS-1255, CHARSET:WINDOWS-1256, CHARSET:WINDOWS-1257,
CHARSET:WINDOWS-1258, CHARSET:HP-ROMAN8, CHARSET:NEXTSTEP.
* The functions
OPEN, MAKE-PIPE-INPUT-STREAM, MAKE-PIPE-OUTPUT-STREAM, MAKE-PIPE-IO-STREAM,
SOCKET-ACCEPT, SOCKET-CONNECT
and the macro
WITH-OUTPUT-TO-PRINTER
accept a keyword argument :EXTERNAL-FORMAT. Possible values are encodings,
such as returned by the function MAKE-ENCODING, the line terminator keywords
:UNIX, :MAC, :DOS, and :DEFAULT. New function STREAM-EXTERNAL-FORMAT.
* STREAM-EXTERNAL-FORMAT is SETFable. The external format of streams created
by the functions OPEN, MAKE-PIPE-INPUT-STREAM, MAKE-PIPE-OUTPUT-STREAM,
MAKE-PIPE-IO-STREAM, SOCKET-ACCEPT, SOCKET-CONNECT can be modified.
* OPEN has a new keyword argument :BUFFERED. It determines whether the file
stream returned is buffered or not. Possible values for it are NIL, T, or
:DEFAULT. If it is :DEFAULT, buffered file streams will be returned for
regular files and (on Unix) block-devices, and unbuffered file streams for
special files.
* The functions MAKE-PIPE-INPUT-STREAM, MAKE-PIPE-OUTPUT-STREAM,
MAKE-PIPE-IO-STREAM, SOCKET-ACCEPT, SOCKET-CONNECT have a new keyword
argument :BUFFERED. It determines whether the stream returned is buffered or
not. Possible values for it are NIL, T, or :DEFAULT. :DEFAULT is equivalent
to NIL.
* New functions READ-INTEGER, WRITE-INTEGER which can be used to do binary I/O
on streams with element-type (UNSIGNED-BYTE 8).
* The Gray proposal <STREAM-DEFINITION-BY-USER> is implemented:
New classes
FUNDAMENTAL-STREAM,
FUNDAMENTAL-INPUT-STREAM, FUNDAMENTAL-OUTPUT-STREAM,
FUNDAMENTAL-CHARACTER-STREAM, FUNDAMENTAL-BINARY-STREAM,
FUNDAMENTAL-CHARACTER-INPUT-STREAM, FUNDAMENTAL-CHARACTER-OUTPUT-STREAM,
FUNDAMENTAL-BINARY-INPUT-STREAM, FUNDAMENTAL-BINARY-OUTPUT-STREAM.
New generic functions
STREAM-READ-CHAR, STREAM-UNREAD-CHAR, STREAM-READ-CHAR-NO-HANG,
STREAM-PEEK-CHAR, STREAM-LISTEN, STREAM-READ-CHAR-WILL-HANG-P,
STREAM-READ-CHAR-SEQUENCE, STREAM-READ-LINE, STREAM-CLEAR-INPUT,
STREAM-WRITE-CHAR, STREAM-LINE-COLUMN, STREAM-START-LINE-P,
STREAM-WRITE-CHAR-SEQUENCE, STREAM-WRITE-STRING, STREAM-TERPRI,
STREAM-FRESH-LINE, STREAM-FINISH-OUTPUT, STREAM-FORCE-OUTPUT,
STREAM-CLEAR-OUTPUT, STREAM-ADVANCE-TO-COLUMN,
STREAM-READ-BYTE, STREAM-READ-BYTE-SEQUENCE,
STREAM-WRITE-BYTE, STREAM-WRITE-BYTE-SEQUENCE.
The functions CLOSE, OPEN-STREAM-P, STREAM-ELEMENT-TYPE are now generic
functions.
See <http://clisp.org/impnotes/gray.html> for details.
* The macros FFI:DEF-C-CALL-OUT and FFI:DEF-C-CALL-IN now add an argument
:LANGUAGE :STDC (means ANSI C) instead of :LANGUAGE :C (means old K&R C).
* Conforming with ANSI CL, SIMPLE-CONDITION now has the initarg
:FORMAT-CONTROL instead of :FORMAT-STRING. New function
SIMPLE-CONDITION-FORMAT-CONTROL.
* Conforming with ANSI CL, FILE-LENGTH and FILE-POSITION, when called on
an unbuffered file stream, now return NIL instead of signaling an error.
* Conforming with ANSI CL, MACROEXPAND and MACROEXPAND-1 now accept NIL as
second argument, denoting the global environment.
* Conforming with ANSI CL, the reader now signals an error of type
READER-ERROR when trying to parse tokens like 35/000 or 1.5e1000,
instead of DIVISION-BY-ZERO and FLOATING-POINT-OVERFLOW, respectively.
* On Unix, calling OPEN on a block device now returns a buffered stream
instead of an unbuffered stream.
* On Unix, writing to a pipe created by MAKE-PIPE-OUTPUT-STREAM or
MAKE-PIPE-IO-STREAM after the corresponding child process has exited
now leads to an error message instead of terminating the CLISP process.
* The generic function GENERIC-STREAM-LISTEN is replaced with
GENERIC-STREAM-READ-CHAR-WILL-HANG-P.
* The function XGCD now really always returns coefficients of smallest
possible absolute value.
* Fixed a interpreter bug: (let (x) (declare (special x)) ...) did not change
the global value of x in interpreted mode.
* Fixed a bug: On Win32, Ctrl-Z sometimes caused two levels of the read-eval-
print loop to be aborted instead of just one.
* Fixed a bug: READ-CHAR-SEQUENCE, when called on a string input stream,
forgot to advance the pointer into the string.
* Fixed a bug: WRITE-CHAR-SEQUENCE on Win32 failed to convert NL to CR/LF.
* Fixed a bug: Calling (GET-DISPATCH-MACRO-CHARACTER disp-char sub-char) would
crash, instead of returning NIL, if there is no macro-character function
associated with sub-char after disp-char.
* Fixed a bug: (CHECK-TYPE place typespec string) did not evaluate `string'.
* Fixed a bug: Calling the function FINALIZE caused a crash during the next GC
on many platforms.
* Fixed a bug: Calling a generic function without any installed method
resulted in an inappropriate error message, not a call to
NO-APPLICABLE-METHOD.
* Fixed a bug: Closing a SOCKET-SERVER twice, or using a closed SOCKET-SERVER
could result in inappropriate error messages.
* Fixed a bug: (format nil "~@D" 0) ==> "+0" now.
Portability
-----------
* Added support for SPARC running Linux.
* Added support for Apple PowerPC running MacOS X Server (a.k.a. Rhapsody).
* Improved support for m68k running Linux.
* Added build instructions for Win32 using MSVC 6.0.
Other modifications
-------------------
* On Linux 2.2.x with glibc-2.1, Solaris, OSF/1 and Irix, stack overflow is
now caught reliably. Previously, endless recursion in interpreted code could
cause a crash in some cases.
* Speed up the function DIRECTORY on Unix in some cases.
* Speed up compiled calls to LDB, LDB-TEST, MASK-FIELD, DPB, DEPOSIT-FIELD.
2.22 (1999-01-08)
=================
Important note
--------------
* Changed bytecode format. All .fas files generated by previous CLISP versions
are invalid and must be recompiled.
User visible changes
--------------------
* Conforming to ANSI CL issue <SETF-MULTIPLE-STORE-VARIABLES:ALLOW>:
multiple values in ASSERT, ROTATEF, SHIFTF &c.
* Conforming to ANSI CL issue <SETF-OF-VALUES:ADD>: `values' can take
multiple value places in setf &c.
* The variable `*prompt-with-package*' is replaced with `*prompt*',
which can be a function.
See <http://clisp.org/impnotes/prompt.html> for details.
* Conforming with X3J13 writeup <FUNCTION-TYPE:X3J13-MARCH-88>, an error
is now signalled when a lambda expression (not a function) is passed to
APPLY, FUNCALL, SETF SYMBOL-FUNCTION, EVERY, SOME, NOTEVERY, NOTANY,
SET-MACRO-CHARACTER, SET-DISPATCH-MACRO-CHARACTER. The latter two now
accept a symbol instead of a function.
* X3J13 vote <103> = writeup <IN-PACKAGE-FUNCTIONALITY:MAR89-X3J13> is
implemented: COMMON-LISP:IN-PACKAGE is now a macro. LISP:IN-PACKAGE retains
the old semantics as a function.
The syntaxes (IN-PACKAGE "FOO") and (IN-PACKAGE :FOO) work with both
variations.
* X3J13 vote <11> = writeups <CHARACTER-PROPOSAL:2>,
<CHARACTER-LOOSE-ENDS:FIX>, <CHARACTER-VS-CHAR:LESS-INCONSISTENT-SHORT>,
<JUN90-TRIVIAL-ISSUES:24>, <STANDARD-REPERTOIRE-GRATUITOUS:RENAME> are
implemented: Characters do not have font and bits attributes any more.
The following symbols are not exported from package COMMON-LISP any more:
STRING-CHAR STRING-CHAR-P
CHAR-FONT-LIMIT CHAR-BITS-LIMIT
CHAR-CONTROL-BIT CHAR-META-BIT CHAR-SUPER-BIT CHAR-HYPER-BIT
CHAR-BITS CHAR-FONT MAKE-CHAR INT-CHAR CHAR-BIT SET-CHAR-BIT
MAKE-STRING and MAKE-STRING-OUTPUT-STREAM have a new keyword argument
:ELEMENT-TYPE.
New types BASE-CHAR, EXTENDED-CHAR, BASE-STRING, SIMPLE-BASE-STRING.
* X3J13 writeup <SETF-METHOD-VS-SETF-METHOD:RENAME-OLD-TERMS> is implemented:
New function GET-SETF-EXPANSION, new macro DEFINE-SETF-EXPANDER. The old
symbols GET-SETF-METHOD-MULTIPLE-VALUE, GET-SETF-METHOD, DEFINE-SETF-METHOD
are removed from package COMMON-LISP.
* X3J13 writeups <READER-ERROR:NEW-TYPE> and <PARSE-ERROR-STREAM:SPLIT-TYPES>
are implemented: New condition classes PARSE-ERROR and READER-ERROR.
* X3J13 writeup <UNDEFINED-VARIABLES-AND-FUNCTIONS:COMPROMISE> is implemented:
New condition class UNBOUND-SLOT. New function UNBOUND-SLOT-INSTANCE.
* X3J13 writeups <COMMON-TYPE:REMOVE> and <COMPILER-LET-CONFUSION:ELIMINATE>
are implemented: COMMONP and COMPILER-LET are not exported from package
COMMON-LISP any more.
* X3J13 vote <138> = writeup <PEEK-CHAR-READ-CHAR-ECHO:FIRST-READ-CHAR> is
implemented: PEEK-CHAR does less side effects than READ-CHAR followed by
UNREAD-CHAR would do.
* X3J13 writeup <SHARPSIGN-PLUS-MINUS-PACKAGE:KEYWORD> is implemented:
When looking up a feature symbol in *FEATURES*, the package is no longer
ignored. All initial elements of *FEATURES* are now keywords. The reader
binds *PACKAGE* to #<PACKAGE KEYWORD> during #+ and #-.
* X3J13 writeup <SLOT-MISSING-VALUES:SPECIFY> is implemented: Some of the
values of SLOT-MISSING are ignored, depending on context.
* X3J13 writeup <WITH-OPEN-FILE-SETQ:EXPLICITLY-VAGUE> is implemented:
Assigning the variable bound by the WITH-INPUT-FROM-STRING, WITH-OPEN-FILE,
WITH-OPEN-STREAM, WITH-OUTPUT-TO-STRING macros generates a compiler warning.
* X3J13 writeup <SEQUENCE-TYPE-LENGTH:MUST-MATCH> is implemented: The
functions MAKE-SEQUENCE, COERCE, CONCATENATE, MAP, MERGE signal an error
if the result type specifies a length inconsistent with the other arguments.
* X3J13 writeup <SYMBOL-MACROS-AND-PROCLAIMED-SPECIALS:SIGNALS-AN-ERROR> is
implemented: SYMBOL-MACROLET of special variables or constants now signals
an error.
* Conforming with X3J13 writeup <DOTTED-LIST-ARGUMENTS:CLARIFY>, the first
argument of LDIFF may now be a dotted list.
* PATHNAME-MATCH-P and TRANSLATE-PATHNAME now treat missing pathname
components the same as wild ones.
* Renamed function SOCKET-STREAM-PEER-HOST to SOCKET-STREAM-PEER. New
functions SOCKET-STREAM-LOCAL and SOCKET-SERVER-HOST.
* Conforming to ANSI CL, DEFSTRUCT with option :INCLUDE now does not define
accessors which were already defined in a superclass DEFSTRUCT. This solves
the problems that occur when using the same :CONC-NAME for the new and the
inherited structure, without need for the DEFSTRUCT option :INHERIT.
* The functions MAKE-BROADCAST-STREAM, MAKE-CONCATENATED-STREAM,
MAKE-TWO-WAY-STREAM, MAKE-ECHO-STREAM now verify that their arguments are
input streams or output streams, respectively.
* The function EQUALP now ignores the element type of arrays and looks only
at the array contents, as specified by ANSI CL.
* The *FEATURES* list now contains the symbol CLTL2 instead of the symbol
CLTL1.
* The limit for file size of files that can be accessed by CLISP is increased:
4 GB for character streams, 512 MB for integer streams. The previous limits
were 16 MB for character streams, 2 MB for integer streams.
* Fixed a bug: Calling the function INTERACTIVE-STREAM-P with a non-stream
argument could cause a crash.
* Fixed a bug in the LOOP macro: OF-TYPE was not supported in numeric
accumulation clauses (COUNT/SUM/MAXIMIZE/MINIMIZE).
* Fixed a bug in the LOOP macro: The FOR clauses FROM/TO/BY can now be given
in any order.
* Fixed a bug: (UPGRADED-ARRAY-ELEMENT-TYPE 'STANDARD-CHAR) returned T instead
of STRING-CHAR.
* Fixed a bug: The function CERROR signalled an error if more than two
arguments were given and the second argument was a condition.
* Fixed a bug: Hash tables with test #'EQUALP did not work correctly when the
keys are characters, multi-dimensional arrays or pathnames.
* The function VALUES-LIST now verifies that its argument is a proper list.
* The function XGCD now in most cases (but not always) returns coefficients of
smallest possible absolute value. Suggested by the LiDIA group.
Portability

Other modifications
-------------------
2.21 (9 September 1998)
=======================
Important note
--------------
* Changed bytecode format. All .fas files generated by previous CLISP versions
are invalid and must be recompiled.
User visible changes
--------------------
* The 16 MB memory size limit on 32-bit machines is gone. No need for
wide-mode binaries any more. The "makemake" option --with-wide is not
supported any more. The command-line option -W is supported for backward
compatibility, but will be removed in the future.
* New variables *WARN-ON-FLOATING-POINT-CONTAGION* and
*FLOATING-POINT-CONTAGION-ANSI*.
* New function PROBE-DIRECTORY which tests for the existence of a directory.
Suggested by many people.
* New FORMAT directives ~/ (ANSI standard) and ~! (a better alternative).
* ANSI CL variable *PRINT-RIGHT-MARGIN* is implemented.
* The functions WRITE and WRITE-TO-STRING take the :RIGHT-MARGIN key argument.
* X3J13 writeup <TYPE-BOOLEAN> is implemented: New type BOOLEAN.
Suggested by Sam Steingold.
* X3J13 writeup <ARGUMENT-MISMATCH-ERROR-MOON:FIX> is implemented:
Errors during function calls (too few arguments, too many arguments,
invalid keyword arguments, odd number of keyword arguments, unrecognized
keyword arguments) are now of type PROGRAM-ERROR.
* X3J13 writeup <ENSURE-DIRECTORIES-EXIST> is implemented:
New function ENSURE-DIRECTORIES-EXIST.
Suggested by Pierpaolo Bernardi.
* X3J13 writeup <ISO-COMPATIBILITY:ADD-SUBSTRATE> is implemented:
The macro DEFINE-SYMBOL-MACRO is now exported from package COMMON-LISP.
Suggested by Pierpaolo Bernardi.
* X3J13 writeup <DISPLACED-ARRAY-PREDICATE> is implemented:
New function ARRAY-DISPLACEMENT.
* X3J13 writeup <CLASS-OBJECT-SPECIALIZER:AFFIRM> is implemented:
Class objects can now be used as parameter specializer names (not only
symbols and lists of the form (EQL object)).
* X3J13 writeup <COMPILE-FILE-OUTPUT-FILE-DEFAULTS:INPUT-FILE> is implemented:
When :OUTPUT-FILE is given to COMPILE-FILE or COMPILE-FILE-PATHNAME, missing
pathname components are merged in from the input file pathname.
* X3J13 writeup <COMPILE-FILE-PATHNAME-ARGUMENTS:MAKE-CONSISTENT> is
implemented: COMPILE-FILE-PATHNAME accepts any keyword arguments.
* X3J13 writeup <COMPUTE-APPLICABLE-METHODS:GENERIC> is implemented:
COMPUTE-APPLICABLE-METHODS is now a generic function.
* X3J13 writeup <CONDITION-SLOTS:HIDDEN> is implemented: Predefined condition
types have their own private slot names.
* X3J13 vote <57> = writeup <DEFSTRUCT-SLOTS-CONSTRAINTS-NAME:DUPLICATES-ERROR>
is implemented: Different slots in a structure cannot have names whose
SYMBOL-NAME are equal.
* X3J13 writeup <CONS-TYPE-SPECIFIER:ADD> is implemented:
New type specifier (CONS car-type cdr-type).
* X3J13 writeup <DEFMACRO-BLOCK-SCOPE:EXCLUDES-BINDINGS> is implemented:
The implicit BLOCK generated by DEFMACRO and DEFTYPE encloses only the
body forms, not the forms occurring in the lambda list.
* X3J13 writeup <DEFSTRUCT-COPIER:ARGUMENT-TYPE> is implemented:
New function COPY-STRUCTURE.
* X3J13 writeup <JUN90-TRIVIAL-ISSUES:9> is implemented:
New classes GENERIC-FUNCTION, STRUCTURE-OBJECT, CLASS, METHOD. Removed
the type STRUCTURE.
* X3J13 writeup <EVALHOOK-STEP-CONFUSION:X3J13-NOV-89> is implemented:
Do not export EVALHOOK, APPLYHOOK, *EVALHOOK*, *APPLYHOOK* from package
COMMON-LISP any more.
* X3J13 writeup <MACRO-DECLARATIONS:MAKE-EXPLICIT> is implemented: NOTINLINE
declarations of macros having special compiler treatment are now respected.
* X3J13 writeups <DEFSTRUCT-PRINT-FUNCTION-INHERITANCE:YES> and
<DEFSTRUCT-PRINT-FUNCTION-AGAIN:X3J13-MAR-93> are implemented:
DEFSTRUCT accepts an option :PRINT-OBJECT, similar to :PRINT-FUNCTION,
and each of these options causes a method on PRINT-OBJECT to be installed.
* X3J13 writeup <SPECIAL-FORM-P-MISNOMER:RENAME> is implemented: New function
SPECIAL-OPERATOR-P. The function SPECIAL-FORM-P still exists, but its use
generates a compiler warning.
* X3J13 writeup <FLOATING-POINT-CONDITION-NAMES:X3J13-NOV-89> is implemented:
New condition types FLOATING-POINT-INEXACT, FLOATING-POINT-INVALID-OPERATION.
* Fixed a bug: Reading objects in #n# syntax into typed structure slots gave
an error if the structure's constructor was not compiled.
Reported by Sam Steingold.
* BUTLAST and NBUTLAST are now ANSI CL compliant: They signal an error if the
argument is a dotted list of length 0. (Stupid.)
* The macro WITH-OUTPUT-TO-STRING is now ANSI compliant.
* Added FFI support for NetBSD/m68k.
Thanks to Jörn Clausen <joern@techfak.uni-bielefeld.de>.
* Use of the deprecated functions GENTEMP and SET now generates a compiler
warning.
* Stricter syntax checking for DO and DO*.
* When CLOS:CALL-NEXT-METHOD is called with arguments, it is now checked that
the set of applicable methods is the same as for the original arguments, in
interpreted code only.
* The CLX documentation now also exists in HTML format.
Thanks to Gilbert Baumann <unk6@rz.uni-karlsruhe.de>.
* The normal read-eval-print loop does not call (CLEAR-INPUT *STANDARD-INPUT*)
any more. This means that under X11, cut and paste of multiple lines into
an xterm running clisp now works.
Suggested by Sam Steingold.
* When opening socket servers, ignore EADDRINUSE errors coming from other
sockets, in TIME_WAIT or CLOSE_WAIT state, hanging around on the port.
Suggested by Don Cohen.
* Fixed a bug: When *PRINT-PRETTY* = T, (PRINC #\Newline) often caused two
newline characters to be output instead of a single one.
* Fixed a bug: The sequence type functions refused to handle sequence types
of the form ([SIMPLE-]ARRAY eltype 1). SUBTYPEP returned wrong results
for type specifiers of the form ([SIMPLE-]ARRAY eltype n).
* Fixed a bug: GET-MACRO-CHARACTER on a dispatch macro character does not
result in an error any more.
* Fixed a bug in ECASE, ETYPECASE, CCASE, CTYPECASE.
These macros now accept T and OTHERWISE as keys.
* Fixed a bug: OPEN did not accept type specifiers defined by DEFTYPE as
:ELEMENT-TYPE argument.
* Fixed a bug in the LOOP macro: Forms containing REPEAT clauses were
executed too often in the presence of FOR-= clauses.
* Fixed a bug: The SPACE macro returned a list of the form's values, instead
of the values themselves.
* Fixed a bug, implement X3J13 writeup <PRINC-READABLY:X3J13-DEC-91>:
When *PRINT-READABLY* = T, (PRINC string) caused the string to be output
in double-quotes instead of literally.
* X3J13 writeup <IGNORE-USE-TERMINOLOGY:VALUE-ONLY> is implemented:
A "variable is used despite of IGNORE declaration" warning is not emitted
any more for a variable that is only assigned to and not used for value.
Suggested by Pierpaolo Bernardi.
* Fixed a bug in function FILE-AUTHOR on Win32.
* Fixed a bug: CLISP was unable to determine the user's homedir in
certain (obscure) circumstances.
* Do not warn anymore if someone modifies one of the standard generic
functions of CL like PRINT-OBJECT and INITIALIZE-INSTANCE.
Portability
-----------
* Added AmigaOS support for the socket functions. It's not perfect, but
sufficient for writing socket clients.
Thanks to Jörg Höhle.
* Port to Win32 using msvc5. (Previously only msvc4 was supported.)
* Dropped support for pre-ANSI-C compilers.
* Updated support for EMX.
* Dropped support for EMX versions older than 0.9c.
* Added support for PowerPC running MkLinux.
* Removed (incomplete) support for MS Windows 3.1.
Other modifications
-------------------
* `clisp-link' has a new command `run', to run a linking set with some
modules loaded. If CLISP has been configured with option
--with-dynamic-modules, this is much faster than constructing a
temporary linking set.
Suggested by Gilbert Baumann <unk6@rz.uni-karlsruhe.de>.
* Compiling IFs with no else part now produce better code (Jörg Höhle).
* Speed up I/O to *STANDARD-INPUT*, *STANDARD-OUTPUT* and *TERMINAL-IO*:
If standard input is redirected from a file, the input side of *TERMINAL-IO*
will be buffered. If standard output is redirected to a file, the output
side of *TERMINAL-IO* will be buffered.
* Dropped the STDWIN library.
* Added a new type encoding scheme which allows all address ranges from
0x00000000 to 0x7FFFFFFF to be used. This should make porting to some
systems easier.
* Added bindings to libc for Linux with libc6 (aka glibc 2.0).
* Miscellaneous documentation updates.
2.20.1 (6 December 1997)
========================
User visible changes
--------------------
* Fixed a bug which could cause a crash when Ctrl-C was pressed during heap
allocation on i386.
Other modifications
-------------------
* The implementation notes now also exist in HTML format.
2.20 (25 September 1997)
========================
User visible changes
--------------------
* X3J13 vote <53> is implemented: DEFSTRUCT BOA constructors can have &KEY
arguments.
* X3J13 vote <40> is partially implemented: New variable *READ-EVAL*.
* X3J13 vote <150> is implemented: (READTABLE-CASE readtable) can now have
the value :INVERT.
* MAKE-PACKAGE and IN-PACKAGE accept a keyword argument :CASE-SENSITIVE.
Similarly, DEFPACKAGE accepts an option :CASE-SENSITIVE. When its value is
non-NIL, the package will be case sensitive, i.e. the reader will not
case-convert symbol names before looking them up or creating them in this
package. The package names are still subject to (READTABLE-CASE *READTABLE*),
though.
* X3J13 vote <157> is implemented: ROOM accepts an optional argument with
default value :DEFAULT.
* New macro SPACE. (SPACE form) evaluates form and prints information about
the memory allocations caused by this evaluation.
* The spanish translation is now 100% complete. Thanks to Carlos Linares.
* DESCRIBE of a structure now displays the structure's slots.
* The reader now accepts the syntax #\^A ... #\^Z for the ASCII control
characters.
* Fixed a CLOS bug: &ALLOW-OTHER-KEYS in lambda lists of INITIALIZE-INSTANCE
now disables the validity checking of corresponding MAKE-INSTANCE calls.
Thanks to Matthias Lindner <matthias@intellektik.informatik.th-darmstadt.de>.
* Fixed a bug: The type REAL is now accepted as a declaration specifier.
* Fixed a bug: When using GNU gettext, the LOCALIZED function always returned
the value corresponding to language ENGLISH, and the interactive conflict
resolution of some IMPORT/EXPORT package operations aborted with an internal
error.
* Fixed a bug in the foreign function interface: call-ins did not work on
some platforms.
Thanks to Matthias Lindner <matthias@intellektik.informatik.th-darmstadt.de>.
* Fixed a bug: Calling the function SOCKET-SERVICE-PORT with a non-string
argument caused a crash.
* Fixed two bugs which could cause a crash when a GC occurred during an
IN-PACKAGE or during a pathname operation (DOS, OS/2, Win32 versions only).
* Added image support to the clx/new-clx module.
Thanks to Gilbert Baumann <gilbert@ma2s2.mathematik.uni-karlsruhe.de>.
Portability
-----------
* More Win32 support: stack overflow handling, foreign function interface,
more robust memory management.
* Added support for Win32 (WinNT and Win95), using Borland C++.
* Fixed a compilation error when compiling for sparcv8.
Thanks to Hans Adams <adamsh@server.ecomp.de>.
* Updated support for Solaris/x86.
Thanks to Lutz Euler <euler@lavielle.com>.
Other modifications
-------------------
* Reduced the number of conses allocated by calling APPLY on a function with
both &KEY and &REST.
Thanks to Jörg Höhle.
* The CLX documentation can now be viewed in ghostview.
Thanks to Karl M. Hegbloom <karlheg@inetarena.com>.
2.19 (7 August 1997)
====================
User visible changes
--------------------
* Two new add-on modules:
clx/new-clx: Fast Common Lisp to X11 interface. Written by
Gilbert Baumann <gilbert@ma2s2.mathematik.uni-karlsruhe.de>.
clx/mit-clx: Classic Common Lisp to X11 interface.
* (DRIBBLE filename) now appends to the given file instead of overwriting it.
* Fixed a bug: Platform dependent constants are not inlined in .fas files any
more.
* Fixed a bug: Binding *PRINT-PRETTY* to NIL inside a PRINT-OBJECT method or
inside a structure's print-function could result in undefined behaviour.
Thanks to Don Cohen <don@nichimen.com>.
* Fixed a bug: For x a float, (= 0 x) and (EQUALP 0 x) could result in
undefined behaviour.
Thanks to Don Cohen <don@nichimen.com>.
* Fixed a bug: The error message issued by CHECK-TYPE was wrong.
* Fixed a bug: Calling (DRIBBLE pathname) after (DRIBBLE) did not work.
Thanks to Art Nuzzo <artn@bs724.comm.mot.com>.
* Fixed a bug: The WITH-STANDARD-IO-SYNTAX macro caused *PACKAGE* to be bound
to an invalid value.
* Fixed two bugs in the GC (one in the generational GC, one in the
non-generational GC).
Big thanks to Marcus Daniels.
* Fixed a bug: Printing socket streams created by SOCKET-ACCEPT could result
in an error or an endless loop.
Portability
-----------
* Added support for Win32 (WinNT and Win95), using Microsoft Visual C++.
* Added support for Cygwin32 version 18 (Unix emulation on WinNT or Win95).
* Added support for GNU 0.2 (the Hurd). Thanks to Marcus Daniels.
Other modifications
-------------------
* "clisp" can now be called with "-" as argument. The standard input is then
executed by a read-eval-print loop without prompt, while the remaining
arguments will be assigned to the variable *ARGS*.
* Overall speedup by 13% on i386.
2.18 (3 May 1997)
=================
User visible changes
--------------------
* X3J13 vote <182> is now fully implemented: A LET/LET*/COMPILER-LET binding
specification may now be a list of length 1, without initial value.
Thanks to Gilbert Baumann <gilbert@ma2s2.mathematik.uni-karlsruhe.de>.
* X3J13 vote <78> is now fully implemented: FLET, LABELS, MACROLET establish
an implicit BLOCK.
* X3J13 vote <100> is implemented: Hash tables with test function EQUALP.
* X3J13 vote <131> is partially implemented: #P reader macro for pathnames.
* The MULTIPLE-VALUE-BIND macro no longer allows lists as variable
specifications, only symbols.
Thanks to Gilbert Baumann <gilbert@ma2s2.mathematik.uni-karlsruhe.de>.
* DEFCLASS which changes a class is now allowed and generates a warning.
Since UPDATE-INSTANCE-FOR-REDEFINED-CLASS is not supported, it is your
responsibility to not use the old instances afterwards.
Suggested by Brian Dennis <xjam@CS.Berkeley.EDU> and Tobias Kunze
<tkunze@cmsgia.Stanford.EDU>.
* The TIME macro now outputs to *TRACE-OUTPUT* instead of *STANDARD-OUTPUT*.
Thanks to Nathan Sidwell <nathan@bristol.st.com>.
* When the argument of the function TRANSLATE-LOGICAL-PATHNAME is a string,
it is now interpreted as a logical pathname string. Previously, it was
coerced to a pathname through the function PATHNAME, yielding a physical
pathname.
* CLISP now supports more than the three predefined user-interface languages.
New macros DEFLANGUAGE, DEFINTERNATIONAL, DEFLOCALIZED. New function
LOCALIZED. The macros ENGLISH, DEUTSCH, FRANCAIS now work only for strings.
Removed the macro LANGUAGE-CASE.
The implementation uses the GNU gettext library.
Thanks to Ulrich Drepper and Marcus Daniels.
* New user-interface language ESPANOL.
Thanks to Carlos Linares López <clinares@delicias.dia.fi.upm.es> who has
translated about 55% of CLISP's messages to Spanish.
* EQUALP now descends structures (but not CLOS instances!) on all platforms,
as requested by X3J13 vote <71>.
* The EXIT-ON-ERROR macro now also exits when a Ctrl-C interrupt occurs.
Thanks to Roger Kehr <kehr@iti.informatik.th-darmstadt.de>.
* The initial value of *LOAD-PATHS* on Unix is now (#"./" "~/lisp/**/")
instead of (#"./" #"./**/" "~/**/"). To be customized in config.lsp.
* New variable *LOAD-COMPILING*, which provides the default value for the
:COMPILING keyword of function LOAD. The initial value of *LOAD-COMPILING*
can be specified by a command line option.
* Fixed a bug: (VALUES-LIST '()) often returned one value.
Thanks to Gilbert Baumann <gilbert@ma2s2.mathematik.uni-karlsruhe.de>.
* Fixed a bug in the compiler: When optimizing (OR T form), the compiler
could abort with an error message.
Thanks to Nathan Sidwell <nathan@bristol.st.com>.
* Fixed a bug in the DEFSTRUCT macro which caused the compiler to issue
an error message when compiling a structure definition containing a slot
with a constant, non-NIL initializer.
Thanks to Matthias Lindner <lindner@forwiss.uni-erlangen.de>.
* Fixed a bug in the DEFCLASS macro which caused DEFCLASS and DEFINE-CONDITION
to reject the :DOCUMENTATION class option.
Thanks to Don Cohen <donc@isi.edu>.
* Fixed a bug: The use of type specifiers of the form
(FUNCTION argument-types result-type)
within THE, ETHE, LOOP and DEFSTRUCT forms could lead to errors.
Thanks to Marty Shannon <mshannon@i-2000.com>.
* Fixed two bugs in the DRIBBLE function: After calling (DRIBBLE pathname)
followed by (DRIBBLE), *DEBUG-IO* referred to an unwritable stream.
Calling (DRIBBLE pathname) from within a break loop caused some of the
output to be logged twice.
* Fixed a bug in the expansion of deeply nested backquotes.
Thanks to S. Wotherspoon <spoon@hilbert.maths.utas.edu.au>.
* Fixed a bug in the LOOP macro: Stepping for FOR-AS-= clauses
(LOOP ... {FOR|AS} var = form1 THEN form2 ...) could be executed in the
wrong order if form1 is constant and form2 is non-constant.
Thanks to Russell Senior <seniorr@teleport.com>.
* Fixed a bug in /= : When called with more than two arguments, only the
first two arguments were compared; the remaining arguments were ignored.
Thanks to J. V. Needham <jv@rdk840.dfci.harvard.edu>.
* Fixed a bug in EQUAL and EQUALP: displaced strings were not compared
correctly.
* Fixed a bug in EXPT: For x a (COMPLEX RATIONAL) and y = m/2^n, (EXPT X Y)
actually returned x ^ (m/2^(n+32)) instead of x ^ (m/2^n).
* Fixed a bug in TRUENAME on Unix: If "aa.bb" is a symbolic link to "cc",
(TRUENAME "aa.bb") returned "cc.bb" instead of "cc".
* Fixed a bug in the management of add-on modules: On some platforms,
GC in memory images containing add-on modules always crashed.
* Fixed a bug in the generational GC on i386, rs6000, alpha: In some cases,
FFI objects in memory could cause the first "small" garbage collection to
fail.
Thanks to Dr. Werner Fink <werner@suse.de>.
* Fixed a bug in the printing routine for SOCKET-SERVER objects.
Thanks to Alexey Goldin <goldin@spot.uchicago.edu> and Marcus Daniels.
Portability
-----------
* The core of CLISP can now be compiled with a C++ compiler if no C compiler
is available (without readline library, FFI or modules).
* Added support for Mips processors in 64-bit mode.
* Updated support for Linux 2.0.
* Support for immutable objects now works on Linux/ELF. It did already work
on Linux/a.out.
* Updated Amiga support. Thanks to Jörg Höhle <Joerg.Hoehle@gmd.de>.
* Updated Acorn support. Thanks to Peter Burwood <clisp@arcangel.dircon.co.uk>.
* Updated OS/2 support. Thanks to Jörg Diederich <J_Diederich@herlab.ruhr.de>.
* Updated support for Solaris/x86. Thanks to Marty Shannon <mjs@tiaa-cref.org>.
* Fixed a bug which could cause the readline completion to dump core on HP-UX.
* Fixed a bug relating to the read-eval-print loop's return point on some
platforms. Thanks to Peter Burwood <clisp@arcangel.dircon.co.uk>.
* Removed an incompatibility between SPARC/Sun4 and UltraSPARC memory images.
Found by Martin Ginkel <ginkel@iik.cs.uni-magdeburg.de>.
* Removed support for AmigaOS versions < 2.04.
Other modifications
-------------------
* New "makemake" option --with-wide causes normal and wide-mode binaries to
be built and distributed simultaneously. New command-line option -W
for choosing the wide-mode binaries instead of the normal binaries.
* On Unix, "clisp" is now an executable instead of a shell script.
* "clisp" can now be called with a Lisp file as argument. The remaining
arguments will be passed to the Lisp program in the variable *ARGS*.
On Unix, you can thus make Lisp programs executable by putting
"#!/usr/local/bin/clisp" in the first line and doing a "chmod a+x".
* The read-eval-print loop now calls FORCE-OUTPUT after outputting the prompt.
Thanks to Jörg Höhle <Joerg.Hoehle@gmd.de>.
* Support for immutable objects now also works in the WIDE tagging scheme.
* Reduced the startup time by 20-30%.
2.17 (21 July 1996)
===================
Important note
--------------
* Changed bytecode format. All .fas files generated by previous CLISP versions
are invalid and must be recompiled.
User visible changes
--------------------
* X3J13 vote <72> is conditionally implemented: Objects other than symbols,
lists, numbers, characters, string, bit-vectors are now self-evaluating if
*PACKAGE* uses the COMMON-LISP package.
* The package CLOS is now among the default use list of a new package.
(USE-PACKAGE "CLOS") is not needed any more. To use PCL, you now need
to (UNUSE-PACKAGE "CLOS") explicitly.
* The bytecode format is now platform independent. As a consequence,
compiled functions can be printed readably when *PRINT-READABLY* = T.
* Built-in function objects (SUBRs) are now printed readably when
*PRINT-READABLY* = T, instead of signaling an error.
* Added a <c-type>, C-PTR-NULL to the FFI. C-PTR-NULL will convert
NIL objects into NULL pointers (so that type conflicts can be avoided).
* Socket streams are implemented. New functions SOCKET-SERVER,
SOCKET-SERVER-CLOSE, SOCKET-SERVER-PORT, SOCKET-WAIT, SOCKET-ACCEPT,
SOCKET-CONNECT, SOCKET-STREAM-HOST, SOCKET-STREAM-PORT, SOCKET-SERVICE-PORT,
SOCKET-STREAM-PEER-HOST.
See <http://clisp.org/impnotes/socket.html> for details.
Thanks to Marcus Daniels <marcus@sysc.pdx.edu> and
Marco Ramoni <M.Ramoni@open.ac.uk>.
* Pipe streams now support binary I/O.
* MAKE-INSTANCE now also works for DEFSTRUCT classes, and DEFSTRUCT classes
can now be subclassed via DEFCLASS with option :METACLASS STRUCTURE-CLASS.
Suggested by Manuel Kolp <kolp@qant.ucl.ac.be>.
* User defined methods on NO-APPLICABLE-METHOD now have a chance for a
corrective action. Thanks to Mark Thomas <thommark@access.digex.net>.
* APROPOS and DESCRIBE now tell you about symbols which name a type or class.
* During directory search, symbolic link loops are now ignored instead
of resulting in an error. Thanks to Dan Stanger.
* Fixed a CLOS bug: REMOVE-METHOD did not work.
Thanks to Roger Kehr <kehr@iti.informatik.th-darmstadt.de>.
* Fixed a bug in the compiler: A (MULTIPLE-VALUE-SETQ vars valform)
or (MULTIPLE-VALUE-BIND vars valform ...) form was miscompiled if
valform is known to produce a single value.
Thanks to Paul Graham <pg@das.harvard.edu>.
* Fixed at least two bugs in the LOOP macro: FOR-AS-ACROSS clauses could
result in AREF signaling an out-of-bounds error at the end of the vector.
Initialisations for FOR-AS-= clauses could be executed in the wrong order.
* Fixed a bug: the functions ENCODE-UNIVERSAL-TIME and DECODE-UNIVERSAL-TIME
computed a wrong DST flag for time values between (T - 2h) and T, where
T denotes a DST switch time.
* Fixed two bugs in the foreign function interface: multi-dimensional arrays
and floating point numbers with value 0.0 were not correctly passed from
"foreign land" to "Lisp land". Thanks to Ken Olum <kdo@mit.edu>.
* Fixed a bug in the foreign function interface: call-ins which return
structures or unions would not compile correctly. Thanks to Michael Stoll.
* Fixed a bug: On Solaris, the function SYSTEM sometimes reported exit
status 0 although the command had failed.
Thanks to Brian F. Dennis <xjam@cs.Berkeley.edu>.
* Fixed a bug: LOGTEST did not work correctly if both arguments were bignums.
* Fixed a bug in the floating point number printing routine:
In rare cases, a number was printed with more digits than necessary
(without, however, violating the print-read consistency). For example,
2.1416s29 printed as 2.14159s29, and 3.002618f-31 printed as 3.0026179f-31.
* Fixed a bug in ATAN: (ATAN y 0) with y < 0 returned pi/2 instead of -pi/2.
* Fixed a bug in XGCD which caused the results to be wrong with a small
probability, for example in the case (XGCD 77874422 32223899).
Portability
-----------
* FreeBSD/NetBSD patches and compilation notes.
Thanks to Douglas Crosher <dtc@stan.xx.swin.oz.au>.
* Added support for SUNWspro cc 3.0.1 on Sparc.
* Updated support for Ultrix.
* Updated support for NeXTstep version 3.3.
Thanks to Robert Murphy <robert.murphy@yale.edu>.
* Updated support for SINIX. Thanks to Michael Becker <mb12@coconet.de>.
* Fixed a bug in the conversion of double-float numbers from "foreign land"
to "Lisp land" on DEC Alpha. Thanks to Ken Olum <kdo@mit.edu>.
* Fixed a bug in the implementation of LISTEN on Irix: CLISP went into a
`function call not implemented' OS error loop. Thanks to Marcus Daniels.
* Fixed a signal handling bug on some versions of SunOS 4: Strange things
could happen in a break loop.
* The `configure' script now supports the --srcdir, --prefix and --exec-prefix
options.
* Removed support for Atari ST/TT running TOS.
Other modifications
-------------------
* The compiler now recognizes more function calls as inlinable: Cases like
(FUNCALL (LAMBDA ...) ...), (DECLAIM (INLINE F)) (MAPCAR #'F ...)
are now compiled as inline function calls. Previously you had to write
(FUNCTION (LAMBDA ...)) explicitly. Suggested by Jörg Höhle.
* "makemake" now supports the --srcdir, --prefix and --exec-prefix options.
* Added a testsuite for part of CLOS. Thanks to Christian Jullien.
* Miscellaneous documentation updates.

spaces, instead of one. New variable *PRINT-INDENT-LISTS*.
* *PRINT-PRETTY* is now initially T.
* Foreign function interface: New foreign type constructor FFI:C-ARRAY-MAX,
implements zero-terminated arrays of bounded size.
* On Unix, 8-bit characters are legal in pathnames if the operating system
accepts them.
* On DOS, #\Newline is converted to CR/LF when doing character output to
unbuffered file streams (referring to special files).
* Fixed a bug in the interpreter and compiler: A MULTIPLE-VALUE-SETQ form
which assigns to a symbol macro expanded to a wrong form; compiling it
produced a warning. Thanks to Pierpaolo Bernardi.
* Fixed a bug in the compiler: Some CASE form with duplicate keys, when
compiled, chose the wrong clause to be executed.
Thanks to Pierpaolo Bernardi.
* Fixed a bug in the #+/#- reader macros. (LIST #+FOO #-BAR 1 2 3) now
returns (2 3), not (3).
* Fixed a bug in LOG: (LOG x^n x^m), where n, m are integers, |m| > 1, and
x is a rational number /= 1, now correctly returns n/m. Previously,
(LOG 2 4) returned 1/0.
* Fixed a CLOS bug: Using the :DOCUMENTATION option in DEFGENERIC declarations
for function names of the form (SETF symbol) signalled an error.
Thanks to Pierpaolo Bernardi.
* Fixed a bug in DEFSETF: An IGNORE declaration for the store variable had
no effect. Thanks to Pierpaolo Bernardi.
Portability
-----------
* Added support for Linux/ELF. Thanks to Marcus Daniels.

incrementing the counter. New variable *GENSYM-COUNTER*.
* New macro FORMATTER converts a FORMAT control string to a function.
* Some FORMAT fixes:
+ X3J13 vote <81> is implemented: The FORMAT ~:^ directive is more useful.
Warning: Old style "~:^" directives need to be converted to "~#:^".
+ X3J13 vote <82> is implemented: The FORMAT ~D, ~B, ~O, ~X, ~R directives
accept an optional comma-interval parameter.
+ X3J13 vote <84> is implemented: FORMAT ~C outputs characters with no bits
as if by WRITE-CHAR.
+ Handling of ~^ within the FORMAT ~? directive.
* X3J13 vote <167> is implemented: New types FILE-STREAM, SYNONYM-STREAM,
BROADCAST-STREAM, CONCATENATED-STREAM, TWO-WAY-STREAM, ECHO-STREAM,
STRING-STREAM. New functions OPEN-STREAM-P, SYNONYM-STREAM-SYMBOL,
BROADCAST-STREAM-STREAMS, CONCATENATED-STREAM-STREAMS,
TWO-WAY-STREAM-INPUT-STREAM, TWO-WAY-STREAM-OUTPUT-STREAM,
ECHO-STREAM-INPUT-STREAM, ECHO-STREAM-OUTPUT-STREAM.
* New condition type PRINT-NOT-READABLE.
New function PRINT-NOT-READABLE-OBJECT.

function will be called when object is being garbage collected.
* DRIBBLE now also redirects *ERROR-OUTPUT*, *TRACE-OUTPUT*, *QUERY-IO*,
*DEBUG-IO* if they refer to *TERMINAL-IO*.
* Calling SYMBOL-VALUE on a symbol defined as global symbol macro now returns
the value of the expansion. New function SYMBOL-MACRO-EXPAND.
* Add FFI to the *FEATURES* if the foreign language interface is present.
* Fixed a bug: An IGNORE declaration for a macro's &ENVIRONMENT argument now
has an effect.
* Fixed a couple of bugs in the foreign language interface: Passing zero size
arrays did not work, parameters with mode :OUT did not work on SPARC and
HP-PA, and some error messages were deficient.
* Fixed a bogus error message in SET-DISPATCH-MACRO-CHARACTER.
Portability
-----------
* Fixed a couple of building problems relating to the foreign language
interface (missing `mark_fp_invalid' and `pr_hex8', missing makefile
dependencies, support for --with-dynamic-modules, warnings when compiling
user2.lsp and foreign1.lsp).
* Fixed a building problem: Not all C compilers accept casts in constant
expressions used as initializers, e.g. gcc-2.5.8.
* Foreign function interface: Fixed a couple of possible bugs in the low-level
foreign function call routine for i386/486/586, m680x0, SPARC CPUs.
Thanks to Jörg Höhle.
* Small fixes for SCO.
* Added a utility "hln" for making hard links. Needed for "make distrib";
Solaris "ln" does not make a hard link if a symbolic link is involved.

2.14 (4 April 1995)
===================
User visible changes
--------------------
* The initial value of *PACKAGE* can be specified by a command line option.
* X3J13 vote <6> is implemented: New place ROW-MAJOR-AREF.
* X3J13 vote <126> is implemented: New function DELETE-PACKAGE.
* X3J13 vote <14> is implemented: Closing a synonym stream does not close
its constituent stream.
* Foreign language interface for C and ANSI C. New package FFI. New macros
FFI:DEF-C-TYPE, FFI:DEF-C-VAR, FFI:DEF-C-CALL-OUT, FFI:DEF-C-CALL-IN,
FFI:DEF-C-ENUM, FFI:DEF-C-STRUCT, FFI:DEF-CALL-OUT, FFI:DEF-CALL-IN,
FFI:ELEMENT, FFI:DEREF, FFI:SLOT, FFI:CAST, FFI:TYPEOF, FFI:SIZEOF,
FFI:BITSIZEOF.
This currently works only on Unix and only with the CPUs
i386/486/586, m680x0, Mips, SPARC, DEC Alpha, HP-PA, RS/6000.
Warning: (COMPILE-FILE "filename.lsp") now overwrites the file "filename.c".
* New macros MUFFLE-CERRORS and APPEASE-CERRORS. During their execution,
continuable errors are handled by the function CONTINUE. MUFFLE-CERRORS
does this silently, APPEASE-CERRORS prints the error as a warning.
* New macro EXIT-ON-ERROR. During its execution, non-continuable errors
cause CLISP to exit with error status.
* The function ED, when asked to edit a non-existent file, now creates that
file instead of signaling an error.
* When a non-absolute pathname is specified for the -o command line option
(destination file of a compilation), it is interpreted as relative to the
current directory, not relative to the source file of the compilation.
* The readline library now uses the last column of the screen if the terminal
is an xterm, for example. Work done by Chet Ramey.
* Fixed two bugs in the LOOP macro: FOR-AS-ACROSS clauses could result in AREF
signaling an out-of-bounds error at the end of the vector. Initialisations
for FOR-AS-= clauses could be executed in the wrong order.
* Fixed a bug in the compiler which caused LOAD-TIME-VALUE forms to be
evaluated at compile time.
* Fixed a bug in the debugger: Choosing a restart Rnnn always invoked the
last restart listed, not the chosen one.
* Fixed a bug: (CLOSE *TERMINAL-IO*) signals an error again.
* On DOS and OS/2, the Lisp reader now treats Ctrl-Z as whitespace.
* The -I command line option now tells the readline library to handle the Tab
character as normal self-inserting character.
* Unix version only: DISASSEMBLE can display machine instructions, provided
that GNU gdb is present.
Portability
-----------
* Updated support for EMX.
* Fixed a bug which caused a preprocessor error on SunOS and OSF/1.
* Small fixes for Sinix and SCO.

allowed as pathnames.
* Amiga version: SCREEN package is implemented. Thanks to Jörg Höhle.
* The debugger emits some more messages to *DEBUG-IO*, not *ERROR-OUTPUT*.
* (COERCE symbol 'FUNCTION) now works.
* Fixed a bug in ENOUGH-NAMESTRING: In many cases, a relative directory
specification was returned instead of an absolute directory specification.
* Fixed a CLOS bug which caused (DEFCLASS FOO (STANDARD-OBJECT) ()) and
(DEFINE-CONDITION FOO (CONDITION) ()) to signal errors.
* Fixed a bug: In some situations, USE-PACKAGE reported a name conflict when
there was none.
* Fixed a bug: (READ-CHAR-NO-HANG stream nil eof-object) now signals an error
if stream is not an input stream. Previously it returned eof-object.
* Fixed a bug: On some Unix systems, (FINISH-OUTPUT *TERMINAL-IO*) signalled
an error if standard output was redirected to a file.
* (SQRT 0) now returns an integer 0 instead of a floating-point 0.0.
* Readline library: Fixed a small problem with input prompts longer than the
screen width.
* Fixed three bugs in the built-in editor. One of them made the editor
entirely unusable.
Portability
-----------
* Added some support for MS Windows.
* On DOS, the readline library now handles the /!INPUTRC and history files
correctly.
* Some modification for the sake of gcc-2.6.1.
Other modifications
-------------------
* Generational garbage collection now also works on Linux (1.1.52 or newer).
* On Unix, external modules written in C can be linked to CLISP without
recompiling CLISP from source. For example, the STDWIN library.
* Small fix: On some machines, some internal objects were being printed as
#<SYSTEM-POINTER ...> instead of #<FRAME-POINTER ...>.
* Miscellaneous documentation updates.
2.12.1 (1 September 1994)
=========================
User visible changes
--------------------
* The DEFCONSTANT warning about redefinition of a constant is also inhibited
if the constant's new and old values are the same string (in the sense of
EQUAL). Thanks to Marcus Daniels.
* Unix version only: The daylight saving time flag of a time zone (eighth
value of GET-DECODED-TIME and DECODE-UNIVERSAL-TIME) is now correct.

* The function ED can now edit functions that have been entered in
interpreted form even if they have later been compiled.
* New function UNCOMPILE. (UNCOMPILE function-name) undoes the effect of
(COMPILE function-name) if the function's definition had been entered
in interpreted form.
* The OPEN option :IF-EXISTS :RENAME-AND-DELETE now deletes the renamed
file. Previously :RENAME-AND-DELETE was equivalent to :RENAME.
* (LISP-IMPLEMENTATION-VERSION) returns a more precise version string.

Other modifications
-------------------
* Copyright clarification.
* Generational garbage collection. This works only for Unix implementations
with powerful virtual memory management, currently only SunOS.
* Improved virtual memory efficiency:
- Memory model SPVW_PAGES: do not put a piece of management data into
every page.
- Memory model SPVW_BLOCKS: compact conses, do not shuffle them, so that
they are kept sorted according to their age.

of read() for the startup file.
* Added a readline manual page.
* Miscellaneous documentation updates.
2.11 (4 July 1994)
==================
User visible changes
--------------------
* X3J13 votes <115> and <114> are implemented: an elaborate LOOP macro.
New macro LOOP-FINISH.
Warning: The scoping rules for the iteration variables are hairy. If a
FOR/AS initialisation form refers to an iteration variable of a subsequent
FOR/AS clause, the effects are implementation dependent!
* X3J13 vote <120> is implemented: New function MAP-INTO.
* X3J13 vote <79> is implemented: New constants
LEAST-POSITIVE-NORMALIZED-SHORT-FLOAT,
LEAST-NEGATIVE-NORMALIZED-SHORT-FLOAT,

garbage if the current user interface language was not English.
Other modifications
-------------------
* Miscellaneous documentation updates.
2.10 (22 June 1994)
===================
User visible changes
--------------------
* French support is now complete. Thanks to Jörg Höhle.
* The user interface language (English, German or French) can now be chosen
at startup time through a command line option. The constant *LANGUAGE* has
been removed, and its value has been removed from *FEATURES*. New macros
ENGLISH, DEUTSCH, FRANCAIS and LANGUAGE-CASE.
* There is a command line option that makes CLISP behave more like what
ILISP (a popular Emacs LISP interface) expects.
* The function CLOS:CALL-NEXT-METHOD can now be called with arguments, but
the check that the set of applicable methods must be the same as for the
original arguments will be bypassed.
* New functions READ-CHAR-SEQUENCE, WRITE-CHAR-SEQUENCE, READ-BYTE-SEQUENCE,
WRITE-BYTE-SEQUENCE which perform fast block I/O.
* Errors of type FLOATING-POINT-UNDERFLOW are inhibited in floating point
computations (and zero is returned instead) during execution of the new
macro WITHOUT-FLOATING-POINT-UNDERFLOW.
* X3J13 vote <95> is implemented: If the readtable argument passed to
GET-MACRO-CHARACTER and GET-DISPATCH-MACRO-CHARACTER is NIL, the standard
readtable is used.
* PROBE-FILE does not report an error any more if an intermediate directory
in the path does not exist. NIL is returned instead.
* The DEFCONSTANT warning about redefinition of a constant is inhibited if
the constant's new and old values are the same (in the sense of EQL).
Thanks to Marcus Daniels.
* The function INTERACTIVE-STREAM-P knows that if the terminal stream is
referring to a regular file (via input redirection) it is not interactive.
* There is a user programmable kind of streams, called generic streams.
New functions MAKE-GENERIC-STREAM, GENERIC-STREAM-CONTROLLER,
GENERIC-STREAM-P, GENERIC-STREAM-READ-CHAR, GENERIC-STREAM-READ-BYTE,
GENERIC-STREAM-LISTEN, GENERIC-STREAM-WRITE-CHAR, GENERIC-STREAM-WRITE-BYTE,
GENERIC-STREAM-WRITE-STRING, GENERIC-STREAM-CLEAR-INPUT,
GENERIC-STREAM-CLEAR-OUTPUT, GENERIC-STREAM-FINISH-OUTPUT,
GENERIC-STREAM-FORCE-OUTPUT, GENERIC-STREAM-CLOSE.
See <http://clisp.org/impnotes/gstream.html> for details.
Thanks to Marcus Daniels and Don Cohen.
* The macro WITH-OUTPUT-TO-PRINTER may now also work on OS/2.
* Fixed a CLOS bug: Generic functions with both optional and keyword
arguments did not work.
* Fixed a serious bug in the compiler which caused incorrect code to be
generated for functions like (LAMBDA (X) (SETQ X 1)).
* Fixed a serious bug in the compiler which caused the compiler to crash
when compiling functions which contain two or more calls to ASSERT.
* Fixed a bug: The macroexpander of MULTIPLE-VALUE-SETQ built up a
syntactically illegal form.
* Fixed a bug in the reader: When reading pathnames from the syntax
#S(PATHNAME ...), #n# references in pathname components were not
resolved prior to calling MAKE-PATHNAME.
* Fixed a bug in the reader: (read-from-string "1/") signalled an error
of type DIVISION-BY-ZERO.
* Fixed a bug in the terminal stream: If several consecutive READ-LINE
operations on the terminal stream were performed without any text
containing newlines being output between them, the prompt finally got
duplicated and then became longer and longer.
* Fixed a bug in the readline library (bad handling of prompts longer than
one line). Thanks to Marcus Daniels.
Installation
------------
* All non-Unix versions: Setting the local time zone should now be much
easier. 122 time zone names are supported.
Portability
-----------
* Unix version only: Getting the time zone should be more robust.
* Added support for NeXT (68k or i386 CPU) running NeXTstep 3.2.

new variables
*BREAK-ON-SIGNALS*, *DEBUGGER-HOOK*.
See <http://clisp.org/impnotes/conditions.html> for details.
Thanks to David Gadbois who wrote most of this.
* X3J13 vote <40> is partially implemented: New variable *PRINT-READABLY*.
* X3J13 vote <34> is implemented: Arrays and packages may now appear as
constants in compiled code.
* X3J13 vote <90> is implemented: FUNCTIONP on symbols and conses now always
returns NIL. The type FUNCTION is disjoint from SYMBOL and CONS.
(COERCE object 'FUNCTION) is implemented.
Warning: Old style calls like
(FUNCTIONP object)
may need to be converted to
(OR (FUNCTIONP object)
(SYMBOLP object)
(AND (CONSP object) (EQ (CAR object) 'LAMBDA))
)
This fixes a CLOS bug: (TYPEP object 'FUNCTION) was not equivalent to
(TYPEP object (FIND-CLASS 'FUNCTION)).
* Two new debugger commands Break+ and Break- permit to set resp. remove
breakpoints at specified EVAL or APPLY frames.
* Warnings and errors produced by COMPILE-FILE are now accompanied by
source line number information.
* The sub-char passed as second argument to read dispatch macros is now
exactly the first non-digit read from the stream. Previously it was its
upper-case equivalent.
* DEFPACKAGE now accepts an option (:DOCUMENTATION docstring).
* DIRECTORY now accepts a keyword argument :CIRCLE. If it is non-NIL,
the directory search for ".../" and "**/" wildcards on Unix avoids endless
loops that may result from symbolic links.
* The variable *LOAD-PATHS* in the Unix versions of config.lsp now uses
"~/" (the home directory at run time) instead of #"~/" (the home directory
at installation time). Thanks to Gabor Herr.
* Unix and OS/2 versions: New dangerous functions MAKE-PIPE-IO-STREAM,
RUN-SHELL-COMMAND and RUN-PROGRAM.
* Unix version only:
The command shell used by MAKE-PIPE-...-STREAM is now always /bin/sh; the
environment variable SHELL is only used as interactive shell.
Fixed a race condition in the functions EXECUTE, MAKE-PIPE-INPUT-STREAM,
MAKE-PIPE-OUTPUT-STREAM that caused the child process to fail mysteriously.
* Attacks such as (DO-ALL-SYMBOLS (S) (UNLESS (CONSTANTP S) (SET S NIL)))
no longer crash CLISP.
* Fixed a CLOS bug: DEFCLASS failed to signal an error if several direct slots
had identical names.
* Fixed a bug in the reader: When reading hash tables which contain #n#
references, the hash codes must be recomputed after resolving the
references. Thanks to Marcus Daniels.
* Fixed a bug in the printer: Printed representations with two different
#1= definitions could result when PRINT-OBJECT methods were called while
*PRINT-CIRCLE* was true. Thanks to Marcus Daniels.
Portability
-----------
* Fixed five bugs in the number crunching routines that appeared on
64-bit processors or in combination with the WIDE tagging scheme.
* More support for 64-bit processors like DEC Alpha.
* Added support for NeXT running NeXTstep 3.1. Thanks to Marcus Daniels.
* Added support for Amiga 3000 running AMIX Unix. Thanks to Michel Loi.
* Fixed a problem with Ctrl-C on HP-UX. Thanks to Gabor Herr.
* Added support for HP9000/300 running HP-UX. Thanks to Gabor Herr.
* Added support for WATCOM C 9.5 on DOS.
* Amiga version: Tolerate memory outside the 27-bit addressable range.
* Remove support for the Atari ST assembly language version CLISP1.
Other modifications
-------------------
* Added some documentation of the GNU readline library.
* Changed the default memory size back from 2.5 megabytes to 2 megabytes.
* Miscellaneous documentation updates.
2.8 (8 November 1993)
=====================
User visible changes
--------------------
* The STDWIN library can now be made part of CLISP by calling makemake with
argument --with-stdwin.
* X3J13 vote <108> is implemented: New packages COMMON-LISP and
COMMON-LISP-USER.
* X3J13 vote <112> is implemented:
LOAD binds the variables *LOAD-PATHNAME* and *LOAD-TRUENAME*, COMPILE-FILE
binds the variables *COMPILE-FILE-PATHNAME* and *COMPILE-FILE-TRUENAME*.
New variables *LOAD-PATHNAME*, *LOAD-TRUENAME*, *COMPILE-FILE-PATHNAME*,
*COMPILE-FILE-TRUENAME*.
* X3J13 vote <26> is implemented: COMPILE-FILE has a keyword argument :PRINT.
New variables *COMPILE-WARNINGS*, *COMPILE-VERBOSE*, *COMPILE-PRINT*.
* Fixed two bugs in DEFPACKAGE: *PACKAGE* is not modified by DEFPACKAGE
any more, and the :INTERN option now works.
* Fixed FUNCTION-LAMBDA-EXPRESSION such that it works on built-in functions.
Thanks to France Dacar.
* Fixed a serious bug in GCD on 16-bit processors: (GCD x y) with
2^k - 2^(k-16) <= |x|,|y| < 2^k could cause a division by zero.
Portability
-----------
* Added support for DEC Alpha AXP running OSF/1 Unix.
* Added support for Apple Mac II running A/UX.
* Added support for Atari ST/TT running MiNT. Thanks to Scott Kolodzieski.
* Support for SunOS4 cc now works.
* The makefile now also works with "parallel" make utilities (e.g. GNU make
with option -j). Thanks to Rick Sladkey.
* Easier porting: The most dangerous optimizations (inline asm() statements,
global register allocations, ...) are inhibited if CLISP is compiled with
option SAFETY=3.
* Some modifications for the sake of gcc-2.5.
Other modifications
-------------------
* Speed up generic function dispatch.
* Some kinds of objects take less space (all CPUs except 680x0).
* The list of X3J13 votes and their current status in CLISP has been moved
from file `src/defs2.lsp' to file `src/cltl2.txt'.
* The code for setting up a connection to an X server (file `src/socket.d')
has been completely rewritten.
* Miscellaneous documentation updates.
2.7 (27 September 1993)
=======================
User visible changes
--------------------
* COMPILE-FILE now handles top-level forms as described in CLtL2 p. 90:
The macroexpansion of a top-level form is considered a top-level form.
When a top-level form is a PROGN, LOCALLY, COMPILER-LET, SYMBOL-MACROLET
or MACROLET form, the subforms of its body are considered top-level forms
too and are compiled separately.
This allows things like
(PROGN (DEFCONSTANT X 3141) (DEFUN GET-X () X))
or
(PROGN (DEFCLASS SHIP () ()) (DEFUN SHIP-P (X) (TYPEP X 'SHIP)))
to work.
Warning: If you want to inhibit this splitting into separate forms (for
example, because several of the forms refer to the same uninterned symbol),
you have to use (LET () (PROGN ...)) instead of (PROGN ...).
* X3J13 vote <144> is implemented: New macro DECLAIM.
* X3J13 vote <113> is implemented: The macro LOCALLY is now a special form.
* Fixed a serious bug in the compiler: When compiling functions inline
whose parameters are special variables, incorrect code could be generated.
* Fixed a bug in the compiler which caused the compiler to crash in some
rare cases, notably when compiling Garnet-2.2.
* Fixed a bug that prevented the debugger commands DOWN and BOTTOM from
working on Linux and SunOS.
* Fixed a CLOS bug: Specifying &KEY without &REST in generic function
lambda lists did not have the desired effect.
* DEFCLASS supports both :DEFAULT-INITARGS syntaxes.
* DEFGENERIC is more tolerant about invalid declarations.
Portability
-----------
* Added Dynix/ptx Sequent support. Thanks to Esther Davis.
* Added support for RS/6000 CPU and AIX. Thanks to Gabor Herr.
Other modifications
-------------------
* Made the memory allocation and (ROOM), (TIME ...) more virtual memory
efficient (less paging on Unix and DOS). Thanks to Don Cohen.
* Added Geoffrey Gordon's "LISP tutorial".
* Renamed stdwin.lsp to stdwin2.lsp.
* Miscellaneous documentation updates.
2.6.1 (1 September 1993)
========================
Important note
--------------
* Changed bytecode format. All .fas files generated by previous CLISP versions
are invalid and must be recompiled.
User visible changes
--------------------
* Unix version only: The command line option -M now also accepts memory images
that were compressed using GNU gzip.
* Fixed a CLOS bug: MAKE-INSTANCE now behaves as if it were calling
INITIALIZE-INSTANCE, and INITIALIZE-INSTANCE and REINITIALIZE-INSTANCE
behave as if they were calling SHARED-INITIALIZE.
* Fixed a CLOS bug: NO-APPLICABLE-METHOD failed to be called in some cases
when no method was applicable.
* Relating to X3J13 vote <89>: The first argument to the functions FUNCALL and
APPLY, denoting a function, may now also be a list (SETF symbol).
* Fixed a bogus error message that occurred when storing an out-of-range
integer into an array of element-type (UNSIGNED-BYTE 32).
Portability
-----------
* Added NetBSD support. Thanks to Charles Hannum.
Other modifications
-------------------
* Added Jeff Dalton's "brief CLOS guide".
* Miscellaneous documentation updates.
2.6 (22 August 1993)
====================
Important note
--------------
* Changed bytecode format. All .fas files generated by previous CLISP versions
are invalid and must be recompiled.
User visible changes
--------------------
* X3J13 vote <12> is partially implemented: Native CLOS. New package CLOS
containing the macros
DEFCLASS, DEFMETHOD, DEFGENERIC, GENERIC-FUNCTION, GENERIC-FLET,
GENERIC-LABELS, WITH-SLOTS, WITH-ACCESSORS,
the functions
FIND-CLASS, (SETF FIND-CLASS), CLASS-OF, CLASS-NAME, (SETF CLASS-NAME),
SLOT-VALUE, SLOT-BOUNDP, SLOT-MAKUNBOUND, SLOT-EXISTS-P,
CALL-NEXT-METHOD, NEXT-METHOD-P,
NO-APPLICABLE-METHOD, NO-PRIMARY-METHOD, NO-NEXT-METHOD,
FIND-METHOD, ADD-METHOD, REMOVE-METHOD, COMPUTE-APPLICABLE-METHODS,
METHOD-QUALIFIERS, FUNCTION-KEYWORDS, SLOT-MISSING, SLOT-UNBOUND,
PRINT-OBJECT, DESCRIBE-OBJECT, MAKE-INSTANCE, INITIALIZE-INSTANCE,
REINITIALIZE-INSTANCE, SHARED-INITIALIZE,
the classes
STANDARD-CLASS, STRUCTURE-CLASS, BUILT-IN-CLASS, STANDARD-OBJECT,
STANDARD-GENERIC-FUNCTION, STANDARD-METHOD and all predefined classes,
and the method combination
STANDARD.
See <http://clisp.org/impnotes/classes.html> for details.
X3J13 vote <13> is implemented, too.
* X3J13 vote <63> is implemented: DESCRIBE receives the output stream as
optional argument. New function CLOS:DESCRIBE-OBJECT.
* X3J13 vote <149> is implemented: The second argument to SUBSEQ may now
be NIL. Thanks to Thomas Kirk.
* X3J13 vote <175> is implemented: TAILP now also works on dotted lists.
* X3J13 vote <124> is implemented: (DECLARE (OPTIMIZE (DEBUG ...))) is legal.
* The type specifier (EQL object), a synonym for (MEMBER object), is now
implemented.
* New DEFSTRUCT option :INHERIT which is exactly like :INCLUDE except that it
does not create new accessors for the inherited slots. Use this option to
avoid the problems that occur when using the same :CONC-NAME for the new
and the inherited structure.
* Fixed EXPORT and USE-PACKAGE: Do not signal a name conflict between the
symbol being exported and a symbol accessible in the using package if
the latter symbol is on the list of shadowing symbols of the using package.
* Fixed VECTOR-PUSH-EXTEND. It now works on vectors of dimension 0 and
on bit-vectors.
* Fixed PRINT-UNREADABLE-OBJECT: Do not output adjacent spaces.
* Fixed a bug in the reader that caused an endless loop or endless recursion
when resolving #n=/#n# references in objects that already contained cyclic
data structures, e.g. when reading (#1=a #.'#2=(b . #2#) #1#).
* Fixed a bogus error message in the complex number reader.
Portability
-----------
* The DOS README explains how to run CLISP in the DOS box of Microsoft
Windows. Thanks to Ralf Muschall.
* Added Sinix support. Thanks to Manfred Weichel.
* Improved installation on OS/2.
Other modifications
-------------------
* A function proclaimed INLINE will be taken inline in a wider set of
circumstances. (Previously INLINE worked only when that function was being
used in the same file or in a file that REQUIREd the file defining the
function.)
* The compiler now produces better code for (APPLY (FUNCTION fun) args).
* Changed the default memory size from 2 megabytes to 2.5 megabytes.
* Miscellaneous documentation updates.
2.5.1 (17 July 1993)
====================
User visible changes
--------------------
* X3J13 vote <150> is mostly implemented: Reading and printing of symbols
(and characters with bits or fonts attributes) is now affected by
(READTABLE-CASE *READTABLE*), whose value may be one of :UPCASE, :DOWNCASE
and :PRESERVE. New place READTABLE-CASE.
* Support for immutable objects is implemented. Attempts to modify read-only
data will signal an error. Program text and quoted constants loaded from
files are considered read-only data. Never again will you be allowed to
write programs that destructively modify themselves!
This works only for Unix implementations with powerful virtual memory
management, currently only Linux and SunOS. To enable it, you have to
add -DIMMUTABLE to the CFLAGS in the makefile when building CLISP.
* Fixed DEFUN such that
(progn
(flet ((bar (x) (+ x 10))) (defun bar (y) (if (zerop y) 1 (bar (1- y))))
(bar 1)
)
returns 10 instead of 1.
* Fixed a bug in the compiler that caused the compiler to crash by endless
recursion and stack overflow when compiling assignments to symbol macros.
Portability
-----------
* Added support for m88000 CPU.
* Amiga version: detect 68000 CPU, for better use of present memory.
Other modifications
-------------------
* Miscellaneous documentation updates.
2.5 (29 June 1993)
==================
User visible changes
--------------------
* X3J13 vote <89> is implemented: (SETF symbol) is now a valid syntax for a
function name in (funname ...), (FUNCTION funname), (DEFUN funname ...),
(COMPILE funname ...), (DISASSEMBLE funname), (ED funname), FLET, LABELS etc.
New function FDEFINITION.
* X3J13 vote <173> is implemented: New special form SYMBOL-MACROLET. The
macroexpansion environment passed to macro expanders and to MACROEXPAND-1,
MACROEXPAND, GET-SETF-METHOD, GET-SETF-METHOD-MULTIPLE-VALUE now comprises
both the variable environment and the function environment.
New macro DEFINE-SYMBOL-MACRO.
* New macro PRINT-UNREADABLE-OBJECT.
* Fixed a bug: The string comparison functions STRING<, STRING>, STRING<=,
STRING>=, STRING/=, STRING-LESSP, STRING-GREATERP, STRING-NOT-GREATERP,
STRING-NOT-LESSP, STRING-NOT-EQUAL now return the index of the first mismatch
instead of T.
* Fixed a bug: The functions REMOVE-DUPLICATES and DELETE-DUPLICATES produced
an out-of-bounds error when called on a small sequence, with :FROM-END T
argument and without :END argument.
Portability
-----------
* Updated support for DJGPP.
Other modifications
-------------------
* The macros SETF, PUSH, POP, PUSHNEW have been completely rewritten.
* Changed internal representation of special form handlers: They now consume
regular memory. This frees one type tag, which will be used by CLOS
instances.
* Miscellaneous documentation updates.
2.4 (24 May 1993)
=================
User visible changes
--------------------
* New macro DEFPACKAGE.
* New function FUNCTION-LAMBDA-EXPRESSION.
* New package SCREEN containing some functions for random screen access

* X3J13 vote <5> is implemented: The value of *APPLYHOOK* must now be
a function of two arguments.
* X3J13 vote <104> is implemented: COMPILE-FILE now binds *READTABLE*.
* X3J13 vote <161> is implemented: SHADOW now accepts strings as well
as symbols.
* Fixed a bug in the compiler which caused the compiler to crash when
compiling (CASE key ...) forms with constant key.
* Fixed a bug in the compiler which produced unloadable .fas files
when compiling forms like (SETF ... (FUNCTION LIST)).
* Fixed a bogus error message in the AREF function.
* The built-in editor on Unix now handles the Delete key the same way
as the Backspace key or Ctrl-H.
* Fixed a bug in + that occasionally caused (- x x) to return a
long-float zero which was not EQL to the other zeroes of type LONG-FLOAT.
* Fixed a bug: Correctly do round-to-even when adding two long-floats.
* Fixed a bug: The destructive sequence functions DELETE etc. failed to
produce an error when called on a sequence of type LIST and with an :END
argument larger than the list's length.
* Corrected the branch cuts of the complex ATAN and ATANH functions.
Portability
-----------
* 68000 and other versions: Fixed a bug in the low-level division algorithm.

routines.
* Improved efficiency of the WIDE tagging scheme.
2.3 (30 March 1993)
===================
User visible changes
--------------------
* Fixed a bug in + that caused the sign of (+ x y) to be wrong when x and y
were double-floats satisfying 0 < x < -y or 0 > x > -y .
* New special form LOAD-TIME-VALUE.
* The function DIR now sorts its output.
* A new place (DEFAULT-DIRECTORY) manages the "current directory".
* When LOAD is called with a pathname as argument that contains a parent
directory component (".."): Ignore the variable *LOAD-PATHS*, avoid an error.
* Fixed TRACE so that functions calling TRACE are correctly handled by
COMPILE-FILE.
Portability
-----------
* Unix version: Correct handling of system calls that are interrupted
by signals.
* Finished IRIX support.
Other modifications
-------------------
* Miscellaneous documentation updates.
2.2.2 (19 March 1993)
=====================
User visible changes
--------------------
* Replaced variable *TEMPFILE* by a function EDITOR-TEMPFILE.
Portability
-----------
* Unix version: Corrected detection of ANSI C header files.
* Unix version: Check whether signal handlers are automatically reinstalled
when activated.
* Made readline library ANSI C compliant and (on Unix) auto-configuring.
* In case there is no room for three extra bits in a symbol pointer,
allocate three stack words per binding in a VAR frame (instead of two stack
words). This completes the Amiga 3000/4000 version.
* Completed memory model SPVW_PURE_BLOCKS: There is a large contiguous memory
area for each kind of Lisp object. This model is used only if memory can
be allocated at prescribed addresses, for example on Unix with mmap().
* More 386BSD support.
Other modifications
-------------------
* Remove limit on the number of files that may be specified on the command
line. Limit was 1000.
* Miscellaneous documentation updates.
2.2.1 (4 March 1993)
====================
User visible changes
--------------------
* Fixed a bug in ADJOIN that caused ADJOJN and PUSHNEW to push (key item)
instead of item onto the list when a :KEY argument was present.
* Amiga version: allow opening of "files" on special devices.
* OS/2 version: Long filenames on DOS (FAT) filesystems no longer produce
errors. They are now silently truncated to 8+3 characters.
* Unix, Amiga, OS/2 versions: When a pathname is to be fully specified, no
subdirectory wildcard "**/" or ".../" is allowed. Check this.
Portability
-----------
* Corrected underflow detection in SCALE-FLOAT on 16-bit processors.
* Atari ST version: fixed getenv(), wrote INSTALL instructions.
Other modifications
-------------------
* Miscellaneous documentation updates.
2.2 (21 February 1993)
======================
User visible changes
--------------------
* Include test suite into distribution.
* Add COMMON-LISP and CLTL1 to the *FEATURES*.

DO-ALL-SYMBOLS, DOSEQ, DOHASH.
* LISTEN on file streams opened with :DIRECTION :OUTPUT now returns NIL.
* Pathnames resulting from OPEN on special files are now called
"file handle streams", they are unbuffered file streams.
They can now be used as argument in situations where a pathname is expected.
Portability
-----------
* The `target' and `configure' scripts no longer depend on awk.
* Support Sun4 with 32 bit address range (kernel architecture "Sun4m") as
well as Sun4 with 29 bit address range (kernel architecture "Sun4", "Sun4c).
* Can now exploit the shared memory facilities of SunOS 4.1 and of Linux.
* Added support for 386 UHC UNIX System V release 4.
Other modifications
-------------------
* Implemented memory model SPVW_PURE_PAGES where memory is divided
into many small pages each containing objects of the same type.
* Fixed up source for systems without window streams.
* lispbibl.d, constobj.d: reorder the stream types such that the test for
file stream becomes faster.
* /usr/local/lib/aclocal.m4, configure.in, unixconf.h.in: prefix my own local
macros by CL_ instead of AC_.

=======================
User visible changes
--------------------
* Fixed meaning of :KEY argument for SUBLIS and NSUBLIS.
