Version Changes for Hypermail
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 Ashley M. Kirchner (May 31, 2000)
 - I converted all uppercase HTML tags to lowercase in the main hypermail
   base source.  Stuff that got contributed (under the contrib directory)
   were not touched.  I'm going to leave those for their respective
   contributors to change.

 Daniel Stenberg (daniel@haxx.nu) (May 25, 2000)
 - Added 'spamprotect' as a new flag. It replaces @-letters with "_at_" to
   confuse spam-email-robots a bit.

 - Found a terrible bug when an URL contains a @-letter, since it'll first
   become <href>-tagged and then <mailto>-converted... :-/

 - Added https:// as a recognized URL type (deja-vu, didn't I do this before?)

 - Corrected the alternative parser not being reset at the end of all mails

 Daniel Stenberg (daniel@haxx.nu) (May 23, 2000)
 - Corrected the output on %> appearences in the template files

 - Applied the beauty fix supplied by Darryl Lee <lee@darryl.com>

 Daniel Stenberg (Apr 10, 2000)
 - I made %<unknown letter> in printfile display exactly as used the other
   day. Today I changed my email address all over!

 - Added https:// to the recognized URL types to <a>-ify

 Jose Kahan (jose@w3.org) (Jan 17, 2000)

 - The quoted printable decoding didn't take into account the 
   ietf-mbox option.
 
 Jose Kahan (jose@w3.org) (Dec 24, 1999)

 - Removed an invalid </A> tag when using tables.

 - When using the showhtml option, invalid HTML was generated in the
   headers: <P><P> before the </PRE>.
 
- Stopped the generation of a Mailto on msgid's.
 
 - Rearranged the format of the index and messages when not using
   tables. My aim was to make the format more symetrical.

 - Added a new item, "Mail actions",  in the control menu. This item
   is only active when using the mailcommand and hmail options, and
   when the tables are turned off. This option duplicates the one found in 
   the table.

 - Added two new options for linking external stylesheets to the index 
   and the messages, respectively: icss_url, mcss_url. The link is added
   as a META element in the header.

 - The default value of the mailcommand mailto: had some typos: non
   escaped chars, use of reply-to instead of in-reply-to.
 
 - Two protections were missing to avoid having empty HREFs when the
   about and archives options were defined in the .hmrc file, but wihout
   any given value.

Jose Kahan (jose@w3.org) (Dec 15, 1999)

 - The inline changes from 29/Nov had the side effect that other
   inline attachments, like text/html were being linked like inline
   images.

 Kent Landfield <kent@landfield.com> (Dec 8, 1999)

 - Bjarni R. Einarsson <bre@netverjar.is> pointed out that the
   "Reply:" and "Maybe Reply:" output was not correct.  pcm@rahul.net 
   (Peter C. McCluskey) submitted a patch that fixes them as well
   as the current threading allows. 

 Kent Landfield <kent@landfield.com> (Dec 7, 1999)

 - Added hoaf-28 python index generator written and contributed
   by Bernhard Reiter <bernhard@climate2.geog.uwm.edu> to the basline.

 - Added ls2mail script written by David Kilzer <ddkilzer@ti.com>
   to the basline.

 - Converted libcgi.doc to libcgi.html.

 Kent Landfield <kent@landfield.com> (Dec 1, 1999)

 - hypermail-2b28 rolled.

 Kent Landfield <kent@landfield.com> (Nov 29, 1999)

 - Corrected a parsing error in parsemail when dealing with
   attachments.  If the filename was "quoted" things worked
   properly. If the filename was not quoted then the name 
   of the attachment was dropping the first letter of the
   filename and adding '_' to the end. 

 - Corrected a conditional statement that was limiting storage
   of 'inline' types to only recording inline types that were
   of type image/.

 - Changed strstr usage when searching MIME headers to
   use strcasestr instead as the case sensitivity was
   getting in the way. 

 Kent Landfield <kent@landfield.com> (Nov 28, 1999)
 
 - Inconsistencies in write* routines called in hypermail.c
   pointed out by Bernhard Reiter <bernhard@uwm.edu>.  set_* 
   variables were used but still passing values in with the 
   function call.  Removed unneeded parameters.

 Kent Landfield <kent@landfield.com> (Nov 22, 1999)

 - The .hmrc resources didn't seem to override the default values, but 
   rather got added to them.  This was corrected for list usage. If
   a list value is set in the .hmrc file, it should completely replace
   the default values.  This need only occur on the first occurance
   after the builtin initialization.

 - Jeff Katcher pointed out 'At the bottom of index.html and date.html, 
   "Last message date:" is output twice.  It's only present once on the 
   author and subject pages.'  This has been corrected so it is only
   printed once.

 Jose Kahan <jose@w3.org> (Nov 23, 1999)

 - A typo in setup.c:PreConfig gave problems (memory overwrite) when 
   dealing with CFG_LIST configuration options.

 - uudecode wasn't working with the ietf-mbox option. 

 Kent Landfield <kent@landfield.com> (Nov 22, 1999)

 - Error in setting of defaultindex in configure.in caused no index.html
   file to be created. configure.in was corrected to set the default 
   index to "thread" instead of thread.html.

 - Added .indent.pro files to FILES file.

 - Added "-p" option to mkdir so all parent directories will be made if
   needed.

 - Added requests to TODO file.

 Kent Landfield <kent@landfield.com> (Nov 17, 1999)

 - hypermail-2b27 rolled.

 Kent Landfield <kent@landfield.com> (Nov 17, 1999)

 - Changed the install dependencies for the Makefile.in files
   so that install-sh is used through out.

 - Assured all includes are checked for in configure.

 - Updated FILES

 - Corrected dependencies on defaults.h

 Kent Landfield <kent@landfield.com> (Nov 14, 1999)

 - Corrected CFG_LIST storage of defaults other than NULL in
   the function ConfigAddItem().
 
 - Assured struct hmlist variables set_text_types,
   set_inline_types, set_prefered_types, set_ignore_types,
   and set_show_headers set to NULL initially. Othewise
   add_list was checking garbage when called from ConfigAddItem().
 
 - Reworked some of the defaults in setup.c
 
 - Added a dump_configI() routine to print out all internal variables
   for debugging. Use #ifdef DEBUG to get it included.
 
 - Removed unused defines in setup.h
 
 - Added defaults.h.in so sites could setup reasonable global defaults.   
 
 - Added additional configure support for setting defaults for 
   language, htmlsuffix, defaultindex and domainaddr in defaults.h. 
 
 - Added cleanup of defaults.h and mail-archive test directory to Makefile
 
 - Removed old method from Makefile.in and lists.h in the archive directory.
 
 - Regenerated configure from configure.in. 
 
 - Regenerated the dependencies in src/Makefile.in 
 
 - Removed some #if 0 code in date.c  
 
 - Changed strdup calls to strsav calls in getname.c and mail.c
 
 - Cleaned up html page output if usetable was selected. 
 
 - Removed unnecessary variable passing into the writedates(), 
   writethreads(), writesubjects(), writeauthors() routines. 
 
 - Freed up memory alocated for configfile variable. 
 
 - Removed unneeded variables in hypermail.h (previously #if 0'ed) 
 
 - Updated README a bit.

 - Updated Changelog

 Kent Landfield <kent@landfield.com> (Nov 11, 1999)

 - Removed strdup declarations that were causing gcc to fail 
   on certain systems.

 - Added French language support contributed by Nicolas NOBLE 
   <pixels@chez.com>

 - Updated documents about "is" and "fr" language support.

 Kent Landfield <kent@landfield.com> (Nov 9, 1999)

 - Added checking the return value of getpwuid() in readconfigs. If
   the value is NULL then see if the $HOME is set in the environment.
   This avoids a crash for Win32 users who don't bother to set up
   /etc/passwd in cygwin environment.

 - Added support for proper naming of executables (hypermail on 
   Unix hypemail.exe on Dos/Windows/NT).

 - Corrected getlocaltime so it would not print the timezone twice
   if the timezone was also specified in the dateformat directive.

 - Corrected print.c so From: is printed when the email address
   is the same as email name.

 - Removed tests/testhm from the baseline. Replaced it with testhm.in
   so configure can generate the proper path to the test hypermail 
   executable.

 - Modified configure.in so that it can determine if it is running
   in cygwin environment. Added tests/testhm.in support.

 - Removed acconfig.h from the baseline as it is no longer needed
   with the current configure changes.

 - Assured destination directories exist for all installed files.

 - Added uninstall option in makefiles.

 - Cleaned up the docs/Install-win32.txt to reflect the changes made.

 Bjarni R. Einarsson <bre@netverjar.is> (Nov 5, 1999)

 - "is" message table translation.

 - Added a stripsubject feature to hypermail, which
   makes it remove all occurances of a given word from the subject line,
   which is really useful for un-cluttering the subjects of some mailing
   lists (my lists all have their subjects prefixed with [listname]: -
   which is quite redundant in an archive).

 Jose Kahan <jose@w3.org> (Nov 4, 1999)

 - Cleaned a bit the HTML format as well as the arranging of the indexes,
   to make them look a bit more coherent.

 - Commented the code that assumed we have an HTML text when finding a
   line with <HTML>. The best way is to send HTML text using a correct
   content type.

 - New configuration option, custom_archives, that allows to define
   a proprietary HTML text to be shown in the Other mailing archives
   item.
 
 - New configuration option, ietf_mbox, for parsing IETF-formatted mboxes
   (see the doc).

 Jose Kahan <jose@w3.org> (Nov 2, 1999)

 - When using the showhtml option, </PRE> tags were being added to each
   line of the signatures.

 Martin Schulze <joey@infodrom.north.de> (October 27, 1999)

 - Some where the showheaders functionality was lost. It has been
   partially added in.  The 'hm_show_headers = list_of_RFC_Headers_to_display'
   functionality did not work and has been corrected.

 - If the show_headers directive contains the special character ``*'',
   hypermail will display all header lines.

 - Hypermail 2.x can now read hypermail 1.02 config files. Needed
   to assure minimal impact of existing sites that use the older
   version of hypermail. 

 - hmrc.4 and hypermail.1 have been updated.

 Kent Landfield <kent@landfield.com> (October 27, 1999)

 - Edited documentation to the text more readable by using two spaces 
   after a fullstop.  

 - Cleaned up prototypes so they are consistent through out the include files.

 - Found many locations where a local variable was shadowing a global
   variable.  Renamed certain variables to assure no compiler confusion. 

 - Extended the warning switches in WARNINGS in the Makefile.in.

 Kent Landfield <kent@landfield.com> (October 23, 1999)

 - Added additional checks in configure for the operating system. Set -Ae for
   HP-UX and added checks for functions in libsocket and libnsl. Added sanity
   checks to assure you are on the same machine if you are using the existing
   config.cache and added acconfig.h config.guess config.sub support files.
   Additional cleanup to configure.in and a regenerated configure script. 

 Scott Rose <srose@direct.ca> (October 20, 1999)

 - When a URL has trailing punctuation, it is almost certainly not part of
   the URL. This version of parseurl() therefore excludes trailing
   punctuation from URLs it finds.

 - If the content-description of a message was empty, and at the end of a 
   line, the link to the associated attachment was anchored on null text. 
   Fixed to assure the text is anchored on the filename in the generated HTML.

 Scott Rose <srose@direct.ca> (October 19, 1999)

 - Added contrib/canonicalize.pl 

   Comparing two archives is complicated by the fact that each message is
   marked by the time at which it's archived. Attached is a script that
   standardizes that date, if weakly, useful for such comparisons.
   
 - Added contrib/hyperfeed.pl

   Feed messages from an mbox into hypermail one at a time so as 
   to test the incremental mode of hypermail.

 - The idea here is that we are zipping along through an mbox, gathering
   information about a message, when we encounter a "From " line that signals 
   the start of the next message. A side effect is populating dp with the 
   date from that "From " line. In the existing code, that value is copied 
   into fromdate[] just before the old message is hashed, which causes it 
   to be associated with the previous message.  This caused different output
   depending on incremental or mbox updating. This patch corrects that
   by moving the date copy until after the addhash function is called.

 Kent (October 18, 1999)

 - Updated parseurl fuction as done by Scott Rose <srose@direct.ca>
   provided 25% faster processing than the existing version while
   maintaining the same functionality.
 
 Kent (October 8, 1999)

 - Changed msg2archive.c to be able to use the command line

 - Made changes to runtest to assure msg2archive could be tested.
 
 - Added the indent file .indent.pro in archive, src and lib.

 - Ran indent on all sources in archive, src, and lib.

 - Made changes to configure.in to better support libsocket.a

 - Corrected configure.in check from gethostbyname to gethostbyaddr.

 - Added configure check for inet_addr

 - Added addition header checks and function checks in configure.in

 - Regenerated config.h.in with autoheader

 - Regenerated configure with autoconf

 - Updated the source files to use the HAVE_* definitions in config.h
 
 - Minor editing on the README

 - Minor updates to the TODO file and Changelog file.

 - Updated KNOWN_BUGS with the content of tests/Problems

 - Removed tests/Problems from the baseline as it was duplicating
   KNOWN_BUGS

 - Removed src/Formatting from the baselien as it was a junk working
   file of mine that should never have been baselined originally.

 - Added tests/mboxes/embedded.msg as a test file and updated
   tests/testhm to exersize it.

 - Removed the listing for tests/Problems and src/Formatting, while
   adding tests/mboxes/embedded.msg to the FILES file.

 - Added the corrected version of hypetombox.pl done by
   Peter McCluskey (pcm@rahul.net) to the baseline.

 Jose (October 7, 1999)
 
 - Changed the HTML DTD string of the generated strings to HTML 4.0
   Transitional.
 
 - Updated the doc to correspond to the suppression of the
   options's hm_ prefix. Made the doc's HTML documents valid HTML 4.0 docs.

 Kent (September 20, 1999)

 - Cleanup of prototypes.

 - Removed the generated getdate.c from the baseline. (Generated
   from getdate.y.

 - Purified and removed array bounds read problems.

 Daniel (September 17, 1999)
 - Applied language patches from Jyrki Kuoppala <jkp@kaapeli.fi>

 - Applied Kent Landfields lots of changes. getname() is reverted to an older
   version since the newer did out-of-bounds reads.

 - Paul Haldane's fix is applied.

 - Peter C. McCluskey <pcm@rahul.net> suggested fixreplyheader() correction
   has beed applied.

 Daniel (September 13, 1999)

 - Kent Landfield found a bunch of weirdnesses that were corrected, in:
   * threadprint.c/print_all_threads()
   * print.c, makemailcommand() usage
   

 Jose (September 8, 1999)
 - (This is a big commit as I'm merging my independent developments into
   the public hypermail tree, which I'll use from now on)
   If there's a Content-Description header, we now use it to describe
   MIME attachments (unless they are inlined).
   Two new options (see the hmrc.4 or hmrc.html file for more info): 
      + hm_uselock to turn off hypermail's internal locking mechanism
      + hm_usemeta to store the content type of a MIME attachment in a
        metadata file (also available thru commandline option -M)
   If the usemeta option is turned on, the Content-Type header of an
   attachment is stored in a .meta directory (see hmrc.4 or hmrc.html for
   more info). 
   Files where MIME attachments are now prefixed with a two-digit counter,
   a la dd-name. This is to avoid having having to create temporary files,
   and to preserver links.  The counter is incremented for each attachment,
   regardless of it's being inline or not. I disabled the call to emptydir
   as it's not useful (will add it as an option later on).
   External MIME attachments that don't have a filename, are given the name
   dd-part.
   Improved handling of MIME rfc822 attachments. 
   Improved handling of Content-Disposition
  
 Ashley (September 7, 1999)
 - Added configure options for --httpddir, --cgidir and --htmldir with
   Apache's layout as the default (/usr/local/apache)

 Daniel (August 23, 1999)
 - Removed the 40-letter limit for subjects in the thread-index when
   the table option was enabled.

 jose.kahan@w3.org
 - When the boundary is declared without quotes, parse.c failed to get it
   properly.

 - print.c: There was a missing <PRE> and this resulted in a not-readable text

 Daniel (August 10, 1999)
 - I hade a terrible bug that made the attachment directories to get created
   relative the wrong directory! They were also not getting the proper
   permissions set.

 Tim Witham <twitham@pcocd2.intel.com> (August 10, 1999)
 - Had to fix a realloc() with NULL pointer which sunos doesn't handle.

2a24
====
  Daniel (August 9, 1999)
  - I'm consider renaming the series of archives that I'm releasing, back to
    the beta label. It would be more correct. Kent is with us again and I
    don't think anyone is gonna continue on the now forever sleeping
    beta-series. This seems to be the one and only hypermail development
    branch and I believe we now have it stable enough.

  - 'attachmentlink' is a new config file item that controls how attachments'
    links are made. By using this you can make a wrapper cgi script on your
    server that issues a warning to the user that it may be dangerous to run
    attachments or whatever you think is appropriate. Default it behavs as it
    used to do before this feature was added.

  Daniel (August 8, 1999)
  - Applied Jose Kahan <Jose.Kahan@inrialpes.fr>'s patches:
 
    The alternate content parsing was broken in that you couldn't give a list
    of preferences. Also, if you first parse an alternate with a low priority,
    then another one with a higher priority, the memory and, eventually, files
    created to store the former alternate content weren't erased.

    I found a minor bug. When decoding messages with multiple MIME
    attachments, the decode variable (where the content encoding format is
    stored), isn't updated.

  Daniel (August 6, 1999)
   - Fixed the subject overflow

   - Made attachments get saved in their own subdirectories.

2a23
====
  Daniel
  - I'm making a release out of this now since I'm off for a longish
    vacation next week...

  Paul

  - Applied Tom van Alten's patch to correct improper formatting 
    of messages when hm_showhtml = 0 and showheaders = 1.

  - New code to (optionally) accept messages wth no msgid.  Default
    is to require msgids in all messages - use hm_require_msgids = 0 
    to avoid this check.

  - Made handling of duplicate msgids optional.  By default duplicates
    are discarded.  To accept them (replacing the msgid with a generated
    msgid) use hm_discard_dup_msgids = 0.

  - Check return value from addhash when reading old messages.  Messages
    already archived should be valid but safer to check.

2a22
====
  Daniel
  - Applied a boundary parsing bug correcting patch supplied by
    Andreas Fuchs <asf@ycom.at>

  Paul Haldane
  o (May 16th 1999)
    1) changes to the way we construct threadlist (so that all the messages
    that should be in the thread are included even if they don't have valid
    in-reply-to headers)

    2) changes to threadprint.c - simplification of print_all_threads.  Now
    uses the information in threadlist to find the relationship between
    messages.  This speeds things up a bit when adding single messages to
    large archives (I saw a reduction from 28s to 18s for adding a message to
    a 1,100 message archive).  Slight speed-up when converting large archives
    - not as noticeable as a large part of time now seems to be in fopen().

    I've updated/added some comments.

    I've added msgnum to the reply struct - this is just a copy of msgnum in
    ->data->msgnum - this was intended as an optimisation but I suspect it
    doesn't make much difference.

    Threading is now much better (well, I would say that wouldn't I :->).  it
    still gets things wrong occasionally - often not really its fault.  Known
    problems include

    1) duplicate message-ids - results in messages being attached to the wrong
    thread - actually found an instance of this in my test mailbox.  The
    obvious heuristic to avoid this would be to compare the subject as well,
    though this breaks threads where the sender has deliberately changed the
    subject but intends to continue the thread.

    2) occasionally gets messages in the wrong order because they get attached
    to different sub-threads - wouldn't happen if MUAs used in-reply-to.

    I've done a quick tweak to duplicate msgid handling in addhash.  Now
    replaces duplicate msgids with a locally constructed one.  This keeps
    things happier.


2a21
====
  Daniel
  o (May 12th)
    - Added the tests/stdintest.pl script. It is a small perl hack that passes
      a series of generated mails into hypermail on stdin. One by one. I've
      got reports about bugs in that area, but I can't seem to repeat any
      with this tool. I thought I'd better include this here anyway to better
      enable others to run more torture tests on hypermail.

  Paul Haldane

  o (May 6th)
    - Here's a patch that allows the user to decide on the format used to
      present dates on the generated pages.  If dateformat is set then it uses
      that (that's the new functionality) otherwise it uses the standard
      format or euro format depending on the config file.

      I've not given the option to use the date string as originally given in
      the mail message.  This could be done without too much hassle.

  Daniel
  
  o (May 5th)
    - Corrected a crash in parse.c

    - Added a missing "From:" in print.c

    - Made the bin-names get prefixed with "att-" too.

    - Adjusted getname() to skip all starting white spaces and quotes, and
      to skip trailing quotes as well as white spaces.

  o (May 4th)
    - Attachment names could miss the first letter.

2a20
====
  Daniel

  o (May 3 1999)
   - Implementing my new From:-parser into the new source file: getname.c.
     This should hopefully not only be much better at parsing from lines,
     but also to it in a more stable manner.

   - Found some additional problems with From-lines I've tried to correct.
     Like a single-mail archive or mails with no From:-lines at all.
    
  Ron Brogden <rb@islandnet.com>

  o A small correction to hypermail.c lets it compile properly on sunos 4.

2a19
====

  Daniel

  o Now I prefix filenames with "att-" when I save attachments.

  o Several errors correct, most of them by Paul Haldane.

2a18
====

  Daniel

  o (Apr 7 1999)
    - Added 'locktime' as a configurable item. It defines the maximum number
      of seconds to wait for an existing lock to dissapear before it is
      overridden. If this is 0 or less, the lockfile will lose its power
      completely. locktime is 3600 by default.

    - I made the 'indextable' option work as Glen Steward wanted it to (that
      March 30 patch apply wasn't such a big hit). You can either set
      "indextable = on" in the config file or use the -T command line option
      to get the indexes in "table" version.

  Paul Haldane

  o (Apr 7 1999)
    - Major date-parsing re-arrangement. getdate.c added, lots of functions
      patched. Speed improvements.

2a17
====

  Daniel

  o (Mar 30, 1999)
    - First atttempt at applying Glen Steward's table patches. It wasn't
      a complete success but it can be adjusted from here.

  o (Mar 29, 1999)
    - Ashley M. Kirchner found a silly bug that occured if the last mail
      in the box was a double message-id (or similar that makes that
      particular function return NULL).

  o (Mar 25, 1999)
    - Threaded index seems to work yet again!
    - Paul Haldane <Paul.Haldane@newcastle.ac.uk> brought me lots of
      various patches that made hypermail do better! 

  o (Mar 25, 1999)
    - Corrected the problem with "re: subject" and "subject" being sorted
      differently. The explanation was that the "re:" subject had a space
      left in the beginning of the string!

  o (Mar 25, 1999)
    My giant work of redoing things now finally seems to work a little at
    least. What's been done the last week:
    - All emails now get only ONE single struct allocated for it.
    - Remade the hash stuff. Hashed entries in the table only stores a struct,
      links it in the list and POINTS to the email struct.
    - Added a hash on the 'inreplyto' string to better enable finding mails
      a mail replies to.
    - Rewrote the whole darned threaded index functions. threadprint.c is a
      new source file for threaded index functions.
    - All indexes will now have full access to the complete email struct and
      will thus enable dates all over etc. This will enable me to introduce
      a template feature for how to write an entry in an index. I.e what to
      include for each entry, subject, author, date, charset, bla bla bla...
    - Changed the way single mail's "next in thread" links are found.
    - As a "side-effect" I added a filter to prevent the same message ID
      twice. The reason for this is that it is more likely for it to be able
      to screw up the threading if I allow them to co-exist.

  o Ashley M. Kirchner <ashley@pcraft.com> works on the bug report web.

  o (Mar 15, 1999)
    Roman Shterenzon <roman@xpert.com> pointed out a bug in the HTML-reader
    that made hypermail crash if the variables were set to "". I mailed back
    a patch to him I think will correct this problem.

2a16

  Daniel

  o (Mar 14, 1999)
    "text_types" is now a recognized config file item, where you can specify
    MIME types that should be treated by hypermail _exactly_ as if they were
    text/plain.

  o Corrected the list-check routine, so that the items in the list are the
    ones using wildcards. This means that suddenly, all those mime-list items
    support wildcards!

  o (Mar 13, 1999)
    Craig A Summerhill <craig@cni.org> found a bug. It turned out to be the
    fact that parse.c wronly assumed content-type text/plain to use
    ENCODE_NORMAL. It was really silly, since the Content-Transfer-Encoding
    header could've already appeared and stated another encoding!

  o Adjusted configure.in to do a slightly better -libnsl check.

  o (Mar 11, 1999)
    CVS server is up again. Added the UPGRADE file to the tree. Thanks to
    Glen Stewart.

  o (Mar 10, 1999)
    Pretty extensive re-write of parse.c to deal with the
    "Content-Disposition" headers better. That line can give a hint whether
    the file should be stored as a file or showed inlined. It can also
    have the filename (RFC1806 for details).

  o (Mar 10, 1999)
    The CVS server is down due to admin work there.

  o (Mar 10, 1999)
    Fixed parseurl(). It now deals with <www.foobar.com> and similar
    constructions better. Craig A Summerhill <craig@cni.org> reported.

  o (Mar 8, 1999)
    Corrected src/Makefile.in to not use options.h anymore!
    Roman Shterenzon <roman@xpert.com> made me aware of this.

2a15
====
  Daniel

  o (Mar 5, 1999) Made "text" equal text/plain in content-type: header
    lines.

  o Removed options.h completely to reduce the number of mistakes from
    people trying to edit it!

  o (Mar 4, 1999) Applied Glen Stewart's patch to remove a few <li> tags.

  o Bailey, Raymond <bailey9@MARSHALL.EDU> pointed out a problem in the
    getname() function. When you got a mail with a From: line where there
    is a name within quotes that were "attached" to the email part without
    spaces in between as in "name"<email@email.com> the parser failed to
    get a name part of this and caused hypermail to dump core.

  o Alisdair Davey <ard@mithra.physics.montana.edu> Helped me point out
    a bug in mprintf.c. It made the *printf() routines fail on %.*s
    constructions. I am considering an upgrade of the mprintf stuff to
    my newer "trio" stuff...

  o Made %f insert the file name of the generated HTML file in headers
    and footers.

2a14 Pl 2
=========
  Daniel

  o Removed a bug that occured when converting a mail into html that had
    a "in-relpy-to" header but the replied-to mail was not present in the
    mailbox.

2a14 Pl 1
=========
  Daniel (now CVS'ed at cvs.hypermail.yeehaw.net:/cvs/hypermail)

  o Made it de-mime headers even without the mime-version: header present
  

2alpha14
========
  Daniel

  o It should now accept white space in the beginning of config file
    lines.

  o SetupCleanup() bugs somehow, I'm no longer using it == dirty fix.

  o Updated the "name/email" scanner.

  o Total mail counter was wrong when updating.

  o Renamed to alpha to avoid confusion.

2b13
====
  Daniel

  o Two corrections in the mprintf.c. One of them being serious

  o (parse.c) now the QP decoder accepts question marks in the encoded-words

  o Corrected the mprintf() replacement define in mprintf.h

  o Added some more missing free()s in print.c

2b12
====

  Daniel

  o Now strips trailing white spaces from values in the config file if
    written without quotes. Paradise Cowgirl <minerva@phix.com> reported.

  o List types in the config were insanely written and caused memory
    disaster at times. Byron C. Darrah <bdarr@sse.FU.HAC.COM> and
    Jenni Baier <jenni@renewed.net> both probably experienced this.

  o Decreased the amount of memory allocations used when building hash
    tables for index sorting. (see addhash() in struct.c)

2b11
====
 
  Daniel
 
  o Tom von Alten <alien@hpdmlad.boi.hp.com> pointed out a really nasty bug
    in fixreplyheader() I had introduced! :-(

2.0b10
======

  Daniel

  o %c is recognized and replaced with a charset tag in mail headers. It
    should be set as early as possible within the HEAD tag.

  o Saves <!-- charset=blablabla --> in articles.

  o dprintf() was not a successful name, Linux uses it for some odd purpose
    even in stdio.h! :-/ Renamed my line of functions to m*.

  o Adjusted getname() to be slightly smarter.

  o Started working at adding charset to each single mail. It should be stored
    per-mail basis now, even though it is never used anywhere...  It should
    now make a proper META HTTP-EQUIV tag!

2.0b9
=====

  Daniel

  o Added a new -o option that can set any config options on the command line.
    E.g set label with -o "label=my new label".

  o Major rewrites of struct.c. There were just too many functions that
    passed data between them by strcpy()ing them to char buffers. They now
    pass char pointers in a lot higher degree. In fact, there aren't that
    many strcpy()s left in the source now. Not that I notice any faster
    operations, I just know it is neater code.

  o I really don't like the way proto.h has *ALL* prototypes and therefore
    everything is dependent on that file. I've stared to slowly extract the
    protos for each .c file into its own .h file. This will allow me to
    change prototype for a single function without having to recompile the
    whole lot.

  o Added general "Re:" - awareness functions. isre() returns TRUE if the
    input string starts with a re-thing and findre() returns the position
    of the first instance of re in the input string, or NULL if there is
    none.

    It knows and recognizes "Re:", "Fw:" and "Re[<number>]:" strings. If we
    ever intend to support local variations of this, I've now made that
    easier...

  o The new getname() had problems with parens in the real name part when
    quoted. As in 
    From: "Windle, Alan M. (PA62)" <test@site.com>
    It shouldn't be a problem now. It should also work with from-lines like:
    From: ("Windle, Alan M. (PA62)") test@site.com

    There might be an idea to simply ignore everything within that level of
    parentheses. I mean, not add that text to the name.

  o The sorted datelist was broken because I must've destroyed unre() when I
    turned it dynamic. I improved printsubjects() to deal with pointers and
    it now strcpy()s a lot less data.
    
    Did the same change to the printauthors() too.

  o increment and readone are now separate options. Read stdin or use mailbox
    are mutually exclusive but don't modify increment or readone. The
    previous system was very confusing and didn't allow e.g updating an
    archive with two mails passed on stdin!

    I've now tried to update an existing archive with 3 mails passed on stdin
    and it seemed to work. Works if read from a mailbox too. Even works with
    the new -1 flag (to indicate there's one mail only). It has an
    accompanying config file keyword named 'readone'. I think the new -v flag
    is really great for this, cause it shows all built-in variables and kind
    of automatically documents them!

  o Ok, I wasn't aware the config file did assume quotes around the strings.
    I've added support for that (too) now. Distributed this small change
    to Kent, Tom and John as a patch for 2b8.

2.0b8
=====

  Daniel

  (Nov 24, 1998)
  o So, just before I was gonna announce the b7 to the guys I got another
    report from John Petrakis that pointed out two bugs. One bad free() which
    he identified and one From:-line that b7 couldn't get name and email from
    properly. I got really tired and rewrote the whole getname() function to
    work with all the combinations mentioned in the source, and more. I think
    this function also has another benefit: it is easier to read than the old
    one.

  o I found some other bugs with my new setup system which caused the
    hm_htmlbody = NONE to not work. I am actually against that a line that
    says NONE sets it to the default. NONE should be NONE, if the keyword
    isn't used at all it should use the default. Well well, one thing at a
    time I guess.
    

2.0b7
=====

  Daniel (getting deeper and deeper into this now ;-)

  o Entirely new config file parser. Does make adding new config items a
    lot easier and smoother. Run hypermail -v to make it output a fully
    working config file (after reading the given input parameters).

    There is no need for the "hm_" prefix on keywords in the config file. You
    can still use it if you want, but you don't have to.

    Internally, all configurable variables are now named 'set_XXXXX' to better
    make it visible in the code.

  o readoldheaders() is a lot more robust now. The order of the variables are
    not set and empty files no longer cause it to dump core.

  o Hypermail from now on only stores the variables inside HTML files that
    are actually set. name="" is not needed to store.

2.0b6
=====

  Daniel continues:

  o parseemail() and ConvURLs() needed to deal with NULLs better.

  o loadoldheaders() are no longer dependent on the order of the variables
    in previously written HTML files.

  o Mails with no subject confused the parser.c

  o Tom von Alten <Tom_vonAlten@boi.hp.com> sent me two files he appearantly
    got from Kent after the b4 he sent me. (date.c and msg2archive.c)

  o All kinds of lists like hm_show_headers, hm_inline_types and
    hm_ignore_types now offer the below mentioned wildcards.

  o Added dmatch.c for dos-style * and ? wildcard matching.

  o Cleaning up more memory leaks.

2.0b5 as sent to John Petrakis 19 Nov 1998
==========================================

  Daniel:

  o Added 'maketgz' to the archive. It is for creating release archives,
    without having to remove a lot of files first.
    * first asks for the version number of choice
    * uses the file FILES to know what files to include.
    * updates the patchlevel.h file to the entered version number
    * creates the archive with a directory based on the entered version number 
    * names the archive based on the entered version number

  o Added a whole bunch of more free() calls.

  o Inlined HTML that was base64 or uuencoded were not previously dealt with
    properly.

  o Mails with no Message-Id: caused a crash in the hash function.

  o HM_INLINEHTML can now be set to 0 to prevent hypermail from inlining
    mail parts in HTML.

2.0b4 as sent to Tom von Alten Nov 19, 1998.
============================================

  Daniel:

  o Dynamic strings all over. I added a generic dynamic-string system which
    I think works pretty good. Using functions and macros it should also be
    pretty easy to extend, modify and optimize without any other source
    modifications. 

    I had to modify stuff all over the place and pretty much too. I hope I've
    removed at least the worst uses of static buffers and my initial tests
    prove me right. No lenght limits of any fields of a mail is my goal, and
    I think it is a fair goal.

    Beware of leaking memory now though. We need to setup some debug-system
    to track them easily.

    The dynamic string routines could very well be optimized too.

  o My dsprintf system was added. This system offers snprintf() - sprintf with
    a buffer length parameter and aprintf() - returns an allocated string with
    the text. I did this to better deal with fully dynamic buffers.

  o Corrected the swedish texts. All 8bit letters were gone!

  o (Nov 16) I recevied the 981013-b4 version. Started work.

2.0b4
====================

  Kent:
 
  o Date routine corrections.  

       - Y2K capable. Hypermail used a two digit representation
         for the year through out. It now uses a 4 digit representation.

       - In hypermail.h, October was listed in monthdays as only having
         30 days.

       - hypermail did not deal with all the major date string formats. 
         Date: formats starting with a digit (09 Sep 1998 01:27:30 +0300)
         would cause parsing and threading problems. It now supports
         that format.

       - Added code to deal correctly with two digit years.
         The idea as to how to approach this and the basis for
         the solution is thanks to Byron Darrah.

       - Corrected an off by one day error in getyearsecs(). It was 
         adding the current day && adding the hours, minutes, and seconds 
         for that day as well. It only needed to count all the days UP TO
         the current day and then add the hours, minutes, and seconds for
         the current day.

       - Incorrect data type passed to fprint_summary(), needed to be
         long instead of int.

       - Corrected an off by one day in getdatestr(). Days in a month
         start at 1, not 0.

 
  o Add the ability to save hypermail generated html files with any 
    configurable html suffix such as ".htm", ".html" or ".shtml", etc.
    This works for the index files as well as the message files. (New 
    .hmrc variable, hm_htmlsuffix, new environment variable HM_HTMLSUFFIX, 
    and HTMLSUFFIX define in options.h.)

  o Removed a conditional "if (use_mbox) increment = 0;" that was 
    preventing the ability to read one message from a file and update 
    an existing archive and its indexes.

  o Corrected parseurl to allow for a ',' (comma) character to be embedded
    in the URL.

  o Corrected parseurl to allow for a '&' (ampersand) character to be embedded
    in the URL.

  o Using -p with -iu on a new archive directory caused a core dump
    begause 'bignum' was zero.  Corrected to assure bignum > 0.

  o Added language abilities to hypermail. 
         English  - en
         Spanish  - es
         German   - de
         Swedish  - se
    initially supported. (lang.c and lang.h added.)

    Thanks to Francisco Iacobelli <fiacobelli@ibersis.cl> for the
    "es" message table translation.

    Thanks to Martin Schulze <joey@kuolema.Infodrom.North.DE> for the
    "de" message table translation.

    Thanks to Daniel Stenberg <Daniel.Stenberg@sth.frontec.se> for the
    "se" message table translation.

  o Changed how error messages are displayed so options message
    only displayed where appropriate instead of for every message.

  o Corrected getname() to parse yet another funky name format.

  o Corrected printing error when a invalid domain was encountered in
    an email address.

  o Converted some static internal buffers to dynamically allocated ones
    at startup saving 6+K. Also resulted in setstrval() not being needed
    so it was removed.

  o Corrected MIME parsing problem with previously parsed headers.

  o Corrected default labeling problem with stdin generated archives
    when no label is supplied.

  o Fixed hypermail so it would not crash if started with no arguments
    and an article on stdin.

  o Added locking to the archive so that there is less chance of corruption
    of the archive due to multiple copies of hypermail trying to update
    the same archive at the same time with multiple messages.  This could
    be improved so as to check for pid of process that owns it...

  o Extended the configure support.

  o Extended the use of hm_progress so that more information about
    attachment files can be displayed.

  o Updated documentation to reflect changes

  o Corrected getname to deal with names that are all spaces.

  o Corrected configuration variable setting. Moved checks to the
    right place in the code.

  o Hypermail now supports listproc mailboxes as well as general Unix
    formated mailboxes. It does not require that a blank line exists 
    between mail messsages in a mailbox. Thanks to Craig A Summerhill 
    <craig@cni.org> for the push and the test data.

2.0b3  - 8/15/98 
=================

  o Added validation of domains so that the generation of mailto: is
    much more accurate than the previous method.

  o Added support for Content-Disposition MIME Header so as to get the
    filename from the header.

  o Added verification of filenames to assure they are safe to use and
    will not cause filesystem problems

  o Fixed a problem with parsing the ending MIME boundary (it expended headers
    following that)

  o Found and removed a one-byte buffer overflow in the line continuation code.

  o Corrected docs/hypermail.1 and TODO to reflect the proper RFC 822
    parsing was actually included in version 2.0b1

  o Corrected a typo in string.c that prevented the proper generation 
    of mailto: links for email names with numbers [0-9] in them. 

  o Corrected the base64 decoder error which caused files to get an 
    extra zero-byte appended at times. (When storing attachments to disk.)

  o Added additional ported systems to the README

  o Removed the "#ifndef" from the defines in options.h. We do not want to
    inherit any define values from other places. If there are confilcts
    then I need to correct them. Inheriting defines can lead to unforeseen
    results.

  o attachments:
       - comments are now generated in the output mail for each attachment 
         that is written in a separate file. The comment looks like:
            '<!-- attachment="filename" -->' in the standard comment style. 

  o buffers and overflows
    - mdecodeRFC2047() now has an output buffer size argument
    - had to remove the use of rmcr() at two places, since that function uses
      a very strict static buffer limiting the maximum line length pretty bad.
    - parseurl() now features an output buffer size argument
    - parseemail() now features an output buffer size argument
  
  o multipart/alternative 
    - added awareness and parser "intelligence" to pick the last prefered
      content-type within a series of alternatives (as MIME tells us to
      do). This has not yet been very thoroughly tested.
    - added the preferedcontent() function that returns wether a content-type
      is prefered or not (as set with hm_prefered_types). Default prefered 
      type is 'text/plain' (if hm_prefered_types is unused).
  
  o output
    - added the experiment function printhtml(). It strips off unwanted html
      tags from the output, even if they are used in attached HTML files. I.e
      <HTML> and </HTML>.
    - made 'showheaders' not use <BR> or newlines since the BRs are ignored
      anyway, and the newlines are already present in each header line.
    - added 'hm_show_headers' which is a list of what headers to include when 
      the 'showheaders' option is used. For now, it also controls which 
      headers to show when attached mails are shown. Although I can imagine 
      that you'd like separate lists (since for attached mails, you'd like i.e
      subject which you may not need for the main mail itself). If 
      'hm_show_headers' isn't used, all headers will be shown.
    - made the <PRE> system in the printbody() function a little smarter, and
      now it prevents multiple </PRE> and <P> tags better. It did however
      introduce another side effect (although a less serious one imho) and 
      that is an extra pair of <PRE></PRE> after the last attachment when 
      using 'showhtml'.
  
  o parsing
    - made the multi-line merger function to make all lines get a regular 
      white space between them when they're put together. Previously, this 
      character was left as-is, which could be a space or a tab (or any other 
      isspace()) letter.
    - check changed to check for "<!-- received" as the start of parsing
      previous html files in the event that the archive maintainer whishes
      to add comments in the header template HTML files.
    - in_list() now checks for list items case insensitive
    - corrected so Message-ID:, References and Supersedes: lines are not
      converted into mailto: URLs.
    - corrected off-by-one in isquote that was causing array boundary read 
      errors.
    - corrected off-by-one in printbody line output that was causing array
      boundary read errors.

Real thanks are in order for Daniel Stenberg and David D. Kilzer. They helped
greatly with making this release possible by sending in enhancements, comments
and bug fixes.  Thanks Guys!
  
2.0b2  - 6/07/98 
=================

  o Corrected command line processing for individual messages received 
    on standard input.

  o Corrected formating of Next message links when incremental updating 
    is done.

  o Corrected the template filenames in docs/hmrc.html. Added "file" 
    to them.

  o Added additional systems to the list of ported systems.

  o Reset certain options back to the proper defaults.

  o Corrected problem in printbody in regards to printing HTML embedded
    in a message. Still work to do here.

  o Changed address options to assure I didn't get landfield.com 
    information inadvertantly set in hundreds of archives because
    the admins just took the defaults. ;)

2.0b1  6/05/98 - Kent Landfield
===============================

WARNING: There have been too many changes to this version to list them
         all here.  What appears below are some of the highlights.

  o Command line settings override what is in the config file. In the
    past the command line variables were read and set before the config
    file was read. (Needed to get the name of the config file from the
    command line.) This made it hard to have a default list configuration
    file and make single runs with only one variable changed. Now processing
    sets the hypermail internal options by:
  
  	Using Compiled in defaults specified in options.h,
            then reads Hypermail Environment variables if set,
            then looks for and reads any Configuration file specified
        and finally uses the Command line settings specified by the user.

    NOTE: THIS IS DIFFERENT THAN PAST HYPERMAIL USAGE.
  
  o Configurable Setting (.hmrc file) or Compile Time Variable to 
    Domain-ize Addresses -- addresses appearing in the RFC822 field 
    which lack hostname can't be made into proper HREFs when Hypermail
    does it's thing.  They are coded with:  mailto:(no%20email)
  
    Because the MTA resides on the same host as the list, it is 
    often not require to domain-ize these addresses for delivery.
    In such cases, I think it would nice if Hypermail could be 
    programmed to output:  mailto:kent@landfield.com  instead.
    This would probably work well as a *required* definition 
    during compilation; however, it should not simply rely on 
    the output from `hostname` in case you want to override with 
    an MX entry or alternate domain (if you run virtual domains)
  
  o Added capability to have customizable index html headers, message
    html headers and html footers.  Able to use substitution cookies in 
    the header and footer template files.
  
       Substitution cookies supported:
  
           %% - '%' character
           %~ - storage directory
           %e - email addr of message author - Not valid on index pages
           %h - HMURL
           %i - Message-id - Not valid on index pages
           %l - archive label
           %m - Mailto address
           %p - PROGNAME
           %s - Subject of message or Index Title
           %v - VERSION
           %u - Expanded version link (HMURL,PROGNAME,VERSION)
           \n - newline character
           \t - tab character
  
       Additional cookies generate the complete META lines:
  
           %A - Author META HTML - Not valid on index pages
                  <META NAME="Author" CONTENT="name (email)">
           %B - <BODY> html statement
           %S - Subject META TAG - Not valid on index pages
                  <META NAME="Subject" CONTENT="subject">
  
  o Generates META tags in articles Author and Subject.
  
  o Now uses "configure" to generate the makefiles. This is rather
    weak at present and needs to be added to/tested on other systems
    but at least it's a start.
  
  o The config.h was renamed to options.h to support configure usage.
  
  o patchlevel.h added to facilitate better patches in the future. Still
    need to fully integrate it's useage in version displays.
  
  o Added example .rc files to show how to customize list's and their
    looks. 
  
  o Removed the _print.c files that had existed in the 103b2 release and 
    replaced them with template headers/footer files. 
  
  o Extended archive path creation to make missing directories.
  
  o Added capabilities dir pathing to allow archive creation by date 
    variables.
   
        %d - two digit day of month (1-28/30/31)
        %D - three letter day of the week
        %m - two digit month of year (1-12)
        %M - three letter month of year (Jan, Feb, ..., Dec)
        %y - four digit year (1990,..2001)
  
    RC example:           hm_dir = /some/archive/listname/%y/%M
    ENV example:          HM_DIR=/some/archive/listname/%y/%M
    Command line example: -d /some/archive/listname/%y/%M
  
    Expands to:  /some/archive/listname/1998/May
  
    All files would be archived during that run in that directory.
    Subsequent executions will put the messages in the directories 
    according to the date the messages were received on the archive 
    site.
  
  o All "mailto:" links can include the "subject" so that the Subject: 
    line of netscape mailer is automatically filled in.
  
  o Fixed "Re:" and redundant "Re:" variation && MS FW... 
  
  o Greatly enhanced getname() to correctly deal with most all email 
    addresses.  X.400 addresses are not well supported yet. 
  
  o Corrected getreply() to better support the In-Reply-To: formats. The 
    routine needs to revisited when a readline routine is inserted to
    properly deal with continuation lines.
  
  o Added additional documentation describing the Hypermail configuration 
    file.

  o Added additional documentation describing how to customize HTML 
    generated pages.
  
  o Corrected many petty problems such as:
     - recursive '%' substitution.  A % in a subject line could cause 
       an ugly recursion problem in a mail command expansion.
     - title length problem.  Length of a title needs to be limited to 
       less than 64 characters as indicated by HTML specs.
     - Weblinted the generated output and corrected various things.
     - Removed unused and unneeded variables

  o Change various storage length defines in hypermail.h

  o I had all calls to the decodeRFC2047() function moved to *after* the
    merging of long lines.
  
  o decodeRFC2047() now correctly concatenates two succeeding "encoded words".
    I now call the function mdecodeRfc2047() since it now allocates the new
    string.
  
  o Now informs if the attachment wasn't properly decoded when stored to disk.
    This happens if the Content-Transfer-Encoding specified isn't known to
    the parser. When this happens, the attachment is stored as 8bit octet-
    stream.
  
  o Now supports the encoding type 'x-uue' for uudecoding. I think there are
    mailers that use different names for the same encoding type so we better
    watch out for them in the future...
  
  o Added the 'demimed' field to the body struct to keep track of 
    header lines+ that have been RFC2047 converted already.
  
  o Kent Landfield sent me an interesting mail that showed me several weird
    bugs in the MIME area.
     A. The Quoted-Printable decoder bugged. A quick fix solved that.
     B. The quoted printable decoder didn't support unlimited size of the line
        the encoded text decodes into. I wrote a new function that seems to do
        it properly.
     C. Some important headers were not properly supported if they were split
        up on several lines. I had to rewrite the header parsing system to make
        this work. It now scans all headers and concatenate them into single
        lines before any function is trying to parse or decode them.
     D. It also showed a need for a uudecoder for the 'x-uue' encode type. This
        is only noted for the future as I haven't written any decoder for this
        format [yet].
  
  o decodeRFC2047 replaces the former RFC1522 function. I made it support
    'encoded-words' anywhere in the line and several different ones on the
    same line is now supported. The only flaw I'm still aware of now, is that
    if there are two encoded-words next to each other, the result should not
    show the spaces between them. My function unfortunately still does.
  
  o renamed decodeRFC1522 to decodeRFC2045.
  
  o decodeRFC1522 (quoted printable header decoding) didn't do well if the
    ending ?= sequence was in the middle of the line. I think this function
    will need more extensive testing.
  
  o Attached mails' headers (To:, From:, Date: and Subject:) are now shown
    in the html.
  
  o Attached mails that contains attachments did force me to add a stack system
    for the multipart boundary strings. Seems to work now. (Can't wait to see
    an attached mail that contains an attached mail that contains ... )
  
  o strcpymax() introduced to prevent buffer overflows on extra-long headers
  
  o Lines starting with 'from ' messed up the parser pretty badly. It now
    checks for 'From ' lines (case sensitive) with an empty preceding line
    to split mails.
  
  o Now extracts attachments to separate binary files.
  
  o Supports multiple lined headers.
  
  o Supports quoted-printable and base64 encoded headers.
  
  o Supports base64 encoded text/plain
  
  o Rewrote the URL and email parsing to allow multiple URLs and email
    addresses on each line.
  
  o Extended the original functionality to much better deal with MIMEd
    mails and the standards from RFC 1521 and 1522. There are still flaws in
    compliance with those but the majority of all mails using mimed texts
    will be presented in a fairly decent fashion.

Patches Contributed From: David D Kilzer <ddkilzer@ti.com>
-----------------------------------------------------------

  o Fixed problem with 'From: ' header lines in messages with the
    following format: "From: <email@address.com>" wherein the "name"
    from the previous email message would be used instead of reverting
    to the address itself.

  o URLs can now include ampersands (&) if they are preceded by question
    marks (?) in the URL string.

  o Email messages with no Subject line no longer grab the previous
    email's subject.

  o Reworked the order of output so that "message" links are always at
    the top of the page in article pages and date/thread/subject/author
    pages.

  o Now escape '%' in mail URLs.

  o Escape for '+' was wrong, changed to '%2B' (was '%22').

  o Updated replace() function to recurse on 'afterstring' variable
    rather than the whole 'newstring'.  More efficient and allows '%'
    escaping.

  o config.h: Added configuration option for SHOW_MESSAGE_LINKS which
    turns all message headers and footers off (except for the links to
    the date, subject, thread and author pages).  SHOW_MESSAGE_LINKS
    overrides the setting of SHOWREPLIES.

  o print.c (writearticles): Removed use of currentemail, currentid,
    and currentsubject by forcing use of email2, msgid2, inreply2,
    subject2, and name2 when calling struct.c (hashreplylookup).  This
    was needed after I rearranged the order in which articles were
    printed.

  o string.c (convurls): Added code in two locations for the 
    Message-Id code segment to recurse on the remaining portion of the
    line being processed.  Each Message-Id found forces a return from
    convurls() after a recursive call.  This prevents infinite recursion
    (a Bad Thing generally speaking).  Note: we assume that Message-Ids
    and URLs/email addresses do NOT appear in the same line.

  o string.c (convurls): Changed format string from "%.3d" to "%.4d".
    Fixed major bug in outputting links for Message-Ids.

  o string.c (convurls): Fixed assumption in code for identifying
    Message-Ids that there was only one Message-Id per line.  We now
    stop gobbling up text used for a link with a space (' ') or a tab
    ('\t').

  o string.c (convurls): Added int got_question_mark in URL processing
    code to permit an ampersand ('&') in a URL provided it comes after a
    question mark in the same URL (a GET method with POST data).  Added
    one line of code and changed another to accomplish this.

  o string.c (convurls): Added code to check whether the next item to
    URL-ize is an email address (containing an at sign, '@').  If it is,
    we break out of the URL for loop and go process the email address.

  o parse.c (loadoldheaders): Modified initial fgets() call to skip any
    non-comment lines (i.e. "<html>" and "<head>").

  o string.c (makemailcommand): Added code to escape percent signs 
    ('%') when escaping spaces (' ') and plus signs ('+').  Percent 
    signs must be escaped first since other escape sequences use the
    percent sign followed by a two-digit hexadecimal number.  We're now
    a little more MIME-compliant.

  o string.c (replace): Changed the replace() function to recurse only
    on the 'afterstring' portion of the URL instead of the whole rebuilt
    URL.  This is both more efficient and prevents infinite recursion
    problems when escaping percent signs ('%') with '%25'.  

  o string.c (makemailcommand): Fixed escape sequence for plus signs
    ('+') from '%22' to '%2B'.

LOTS of other small patches from lots of other helpful people. I hope to 
be able to more accurately list them in the final 2.0 version.
