  *) Changed the late-1.3 log_config substitution %c to %X, to log the
     status of the closed connection, as it conflicts with the far more
     common, historical ssl logging directive %...{var}c.  [William Rowe]

  *) Added the common error/ tree to the build/install targets 
     (similar to the common icons/ tree) for the multi-language error 
     messages that Lars committed earlier.  [William Rowe]

  *) Added a multi process, multi threaded OS/2 MPM mpmt_os2.  [Brian Havard]

  *) Added a default commented-out mod_ldap and mod_auth_ldap
     configuration to httpd-std.conf and httpd-win.conf
     [Graham Leggett]

  *) Added documentation for mod_ldap and mod_auth_ldap.
     [Graham Leggett]

  *) Enabled negative caching on attribute comparisons in the LDAP cache.
     Fixed a problem where the default cache TTL was set in milliseconds
     not microseconds causing the cache to time out almost immediately.
     [Graham Leggett]

  *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
     module code to follow APR. [Graham Leggett]

  *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
     cleaned up when the connection pool pool is cleaned up.
     [Graham Leggett]

  *) Fix a minor issue with Jeff Trawick's mod_include
     patch. Without this patch, the code will just allocate
     more bytes in get_combined_directive than are needed.

  *) Added the LDAP authentication module mod_auth_ldap.

  *) Added the LDAP cache and connection pooling module mod_ldap.
     [Dave Carrigan <dave@rudedog.org>, Graham Leggett]

  *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
     by allowing a module to disable itself if its prerequisites are not
     met.  [Justin Erenkrantz]

  *) Fix a couple of issues in mod_include when the tag appeared at
     offsets near 8192 in the file being parsed.  [Jeff Trawick]

  *) Fix an assertion failure in mod_ssl when the keepalive timeout is  
     reached.  [Jeff Trawick]

  *) Numerous improvements to the Win32 build system.  Introduced command line
     builds without requiring .mak files for MSVC 6.0 and later versions.
     Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
     [William Rowe]

  *) Assorted corrections and improvements to the winnt_mpm startup code.  Better
     reporting of uninstalled services and other error conditions, and changed the 
     default service name to Apache2.  [William Rowe]

  *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm 
     compatibility with existing Apache 1.3 Win32 Apache management utilites.  
     [Mladen Turk <mturk@mappingsoft.com>, William Rowe]

  *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
     [William Rowe, Greg Ames]

  *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
     and RemoveCharset directives.  [William Rowe]

  *) The Unix MPMs other than perchild now allow child server 
     processes to use the accept mutex when starting as root and 
     using SysV sems for the accept mutex.  Previously, this 
     combination would lead to fatal errors in the child server 
     processes.  perchild can't use SysV sems because of security
     issues.  [Jeff Trawick, Greg Ames]

     (including modules/ and support/ tools.)  PR7322  [William Rowe]

  *) Fix ap_rvprintf to support more than 4K of data at one time.

  *) We have always used the obsolete/deprecated Netscape syntax
     for our tracking cookies; now the CookieStyle directive
     allows the Webmaster to choose the Netscape, RFC2109, or
     RFC2965 format.  The new CookieDomain directive allows the

  *) Tweak server/Makefile so that the rules for generating exports.c
     are compatible with make utilities which don't expand wildcards
     in a dependency list (e.g., OS/390 make, certain levels of GNU
     make).  [Jeff Trawick]

  *) Install the SSL headers.  [John Sterling <sterling@covalent.net>]

  *) Begin to sanitize the MPM configuration directives.  Now, all
     MPMs use the same functions for all common MPM directives.  This
     should make it easier to catch all bugs in these directives once.

  *) Close a major resource leak.  Every time we had issued a
     graceful restart, we leaked a socket descriptor.
     [Ryan Bloom]

  *) Fix a problem with the new method code.  We need to cast
     the 1 to an apr_int64_t or it will be treated as a 32-bit
     integer, and it will wrap after being shifted 32 times.
     [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]

  *) Fix a bug in mod_expires.  Previous to this patch, if you
     told mod_expires to add 604800 seconds to the last-modified
     time, it actually added 604800 usec's to the last-modified time,
     so that when looking at the response it looked like nothing
     had been done.  The root of the problem was that we always compute
     time in usec's, but we ask users to input sec's.  This means we
     need to convert to usec's before using those values.
     [Ryan Bloom]

  *) The worker MPM now handles shutdown and restart requests.  It

     definitely isn't perfect, but we do stop the servers correctly.
     The biggest problem right now is that SIGHUP causes the server to
     just die.  [Ryan Bloom]

Changes with Apache 2.0.23
  *) Use the prefork MPM by default on Unix.  [various]

  *) Added a systray icon monitor application for Win32.
     [Mladen Turk <mturk@mappingsoft.com>]

  *) mod_rewrite: Fix the line ending on some non-Unix systems for 
     messages written to the rewrite log.

  *) All mod_autoindex query parsing is now quietly quashed with the 
     IndexOption IgnoreClient.  The IndexOption SuppressColumnSorting 
     still drops the column sort <a href>'s for the column headers, but 
     IgnoreClient is required to ignore these Query options entirely.  
     [William Rowe]

  *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
     to allow the client to select plain, FancyIndexing or HTMLTable
     formatting, V=[0|1] to inhibit or enable version sorting, and 
     P=pattern to return only specific files.  The old Query Arguments
     were reorganized as C=f for sorting column 'f' (same N, D, S, or M
     as before), and O=A|D for ordering ascending or descending.  
     [William Rowe]

  *) Fixed an error in mod_include's directive parsing routines which
     caused #if, #elif, and #else expressions containing backslashes
     to be improperly evaluated.  [Cliff Woolley]

  *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to 
     drop the icon column, SuppressRules to drop the <hr> elements, 
     and HTMLTable to create rudimentary HTML table listings (implies 
     FancyIndexing).  [William Rowe]

  *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
     from Apache 1.3.15.  This is needed for two reasons, first, given
     multiple machines within a server farm, ETags and Last-Modified 
     stamps won't correspond from machine to machine, and second, many 
     Unixes don't capture changes to the date or time stamp of existing 
     files, since these don't modify the dirent itself.  [William Rowe]

  *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst 
     and DirectoryWidth options from Apache 1.3.10. 
     [William Rowe, Ken Coar]

  *) Eliminated FancyIndexing directive, deprecated early in Apache
     1.3 by the IndexOptions FancyIndexing syntax.  [William Rowe]

  *) mod_autoindex now excludes any file names that would result in
     an error, other than a success or redirect.  Also optimized
     the parent directory, always included except in the URI '/'.

     negotiated index pages, and prevent the server from defaulting

     to an autoindex of the directory.  mod_negotiation will now die
     with a 500 Internal Error if it could match some filenames 
     (e.g. for mod_dir) but none can be served.  mod_negotation now
     refuses to serve any file with an extention that mod_mime doesn't
     recognize, and wasn't part of the request.  [William Rowe]

  *) Eliminate mod_cgi's handling of .exe files without the .exe file
     extension.  This is already handled by multiviews, if the admin
     wishes to AddHandler .exe or define a content type handler and

     associate .exe files with that content type.  Multiviews must be
     enabled to allow these to be served.  [William Rowe]

  *) Speed up the server's response to a spike in incoming workload
     or restarts by assigning empty scoreboard slots to new processes
     when they are available.  [Greg Ames]
