<P>
Note that this is a <STRONG>major new distribution</STRONG> and lots
of things have changed. Consult the <A HREF="hylafax4.0.html">general overview</A>
for a high-level description of the new functionality provided in the
v4.0 software.
<P>
This document describes the changes made to the software between the
<I>previous</I> and <I>current</I> versions (see above).
If you don't find something listed here, then it was not done in this
timeframe, or it was not considered important enough to be mentioned.

<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
<UL>
<LI>the zlib and regex packages that are included in the distribution
(from elsewhere) have moved to top-level directories and their
use is now optional; this makes it possible, for example, to link
against a pre-built DSO
<LI><B>configure</B> now automatically purges any <B>config.cache</B>
file if configuration parameters are specified on the command line
or if a <B>config.site</B> or <B>config.local</B> file has been
modified since <B>config.cache</B> was last written
<LI>several fatal errors during configuration now elicit more verbose
information from <B>configure</B>
<LI><B>configure</B> now aborts if the <TT>strftime</TT> or <TT>socket</TT>
functions are not located in the expected places
<LI>a bug was fixed where <B>configure</B> would inject diagnostic information
in the <B>port.h</B> file if memory mapped files were not found to be
supported in the expected way
<LI>the <TT>ZLIB</TT>, <TT>LIBZ</TT> and <TT>ZLIBINC</TT>
configuration parameters were
added to specify the location of the zlib software
<LI>the <TT>REGEX</TT>, <TT>LIBREGEX</TT> and <TT>REGEXINC</TT>
configuration parameters
were added to specify the location of the regex software
<LI>several extraneous references to the math library (<TT>-lm</TT>)
were removed from Makefiles
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxq"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXQ:</B></A>
<UL>
<LI>a bug was fixed that caused active jobs to be terminated when
they were to be suspended
<LI>aborting outbound jobs is now handled better
<LI><B>faxq</B> now waits for sub-processes to terminate when a job
is to be suspended or aborted; this corrects a race condition
that caused clients to sometimes get incorrect results
<LI>a bug was fixed where a reference to a job might be left on
the active queue when faxq could not fork to startup a sub-process
<LI><B>faxq</B> now honors a job's state when initially scanning the
job queue at startup; this means, in particular, that suspended
jobs are no longer automatically submitted
<LI>the scheduling algorithm was reorganized so that jobs are
processed ``more aggressively''; this causes jobs to be dispatched
in an order that more closely parallels the order in which they
are submitted
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxsend"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXSEND:</B></A>
<UL>
<LI>the total number of pages to send--as seen by the client--is now
properly maintained
<LI>a bug was fixed that caused certain abort requests to be ignored
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="pagesend"><B><FONT SIZE=+3>C</FONT>HANGES TO PAGESEND:</B></A>
<UL>
<LI>a bug was fixed that caused certain abort requests to be ignored
<LI>a bug was fixed that caused non-default parity settings to not be
handled properly
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxgetty"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXGETTY:</B></A>
<UL>
<LI>a portability problem that caused core dumps on 68K systems was fixed
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxqclean"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXQCLEAN:</B></A>
<UL>
<LI>malformed job files are now removed instead of being ignored
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="hfaxd"><B><FONT SIZE=+3>C</FONT>HANGES TO HFAXD:</B></A>
<UL>
<LI><TT>JPARM DOCUMENT</TT> now returns the set of document files for a job
<LI><TT>JPARM COVER</TT> now returns any cover page document for a job
<LI><TT>JPARM POLL</TT> now returns any polling requests for a job
<LI><TT>JPARM</TT> now includeds document and polling information in the
status information it returns
<LI>the <TT>%P</TT> and <TT>%y</TT> job status format escapes now correctly
return the total number of pages to be sent for a job
<LI>the SNPP support now correctly resets state after each <TT>PAGE</TT>
request (per the spec)
<LI>the SNPP <TT>SUBJ</TT> command now properly parses multi-token arguments
<LI><TT>JPARM COMMID</TT> now returns the last communications identifier
for a job
<LI><TT>JPARM</TT> requests now work correctly when a job's state
is updated by an unrelated thread of control
<LI>the setting of many job parameters that have side effects
is now handled properly;
in particular this fixes a problem where setting a job's scheduling
priority had no effect
<LI>a bug was fixed in the <TT>%h</TT> job status format escape
<LI>a <TT>%W</TT> job status format escape was added for printing a
job's communication identifier
<LI>a <TT>JINTR</TT> command was added that acts just like <TT>JSUSP</TT>
except that an active job is aborted before it is suspended
<LI>a bug was fixed that caused <TT>STOR</TT> requests that created
a new file to fail
<LI>a bug was fixed the permited unprivileged users to create files
in private directories
<LI>a portability problem was fixed for DEC Alpha systems
<LI><TT>RETP</TT> is a new request that returns a single page from a
TIFF document file; it can be used together with the <TT>REST</TT>
request to selectively retrieve pages from a file
<LI>a bug was fixed in the ZIP-compressed retrieval of files
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="sendfax"><B><FONT SIZE=+3>C</FONT>HANGES TO SENDFAX:</B></A>
<UL>
<LI>the <TT>CoverCmd</TT> configuration parameter now specifies the
absolute pathname for the program to use in generating cover pages
<LI>strings passed as arguments to the <TT>CoverCmd</TT> program are
no longer interpreted by the shell
<LI>jobs are not submitted if a cover page cannot be created (jobs
used to be submitted without a cover page)
<LI>a bug was fixed that caused certain configuration parameters to
be ignored
<LI>the argument sent for the <TT>USETAGLINE</TT> job parameter is
now properly typed as boolean
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="sendpage"><B><FONT SIZE=+3>C</FONT>HANGES TO SENDPAGE:</B></A>
<UL>
<LI>the <TT>-s</TT> option is now correctly recognized
<LI>a bug was fixed that caused reading messages from files to fail
<LI>the <TT>SNPPSERVER</TT> environment variable is now correctly honored
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxmail"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXMAIL:</B></A>
<UL>
<LI>support was added to parse and specially format MIME-encoded messages
<LI>support was added to directly deliver facsimile
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="misc"><B><FONT SIZE=+3>C</FONT>HANGES IN MISCELLANEOUS STUFF:</B></A>
<UL>
<LI><B>faxalter</B> now correctly handles ``<TT>-a now</TT>''
<LI><B>faxcover</B> now properly escapes backslash characters in emitted
PostScript strings
<LI>the <B>tiff2fax</B> script now uses symbolic links instead of hard
links when a processing request requires no work; this fixes a problem
where document files were being created with multiple links to them,
causing <B>faxqclean</B> to not remove the files even though they
were unreferenced
<LI>a bug in <TT>killall</TT> emulation function was fixed in
the <B>hylafax</B> system startup script
<LI>the ``at syntax'' support now properly converts times of the form
``120 minutes''
<LI>boolean values in configuration files can now be specified as
``true'' and ``false''
<LI>the <B>ps2fax</B> symbolic link that is installed for the
default PostScript RIP now references Ghostscript and is only
installed if no file exists
<LI>the text to PostScript conversion support was extended and a bug
was fixed in the handling of lines with trailing white space
<LI>client support for retrieving files was extended to support
restarting a previous retrieval request
<LI>an apparent problem in the socket support in SINIX MIPS 5.42 was
worked around
