  *) Fixed file extensions for real media files and removed rpm extension
     from mime.types. PR 26079.  [Allan Sandfeld <kde carewolf.com>]

  *) worker MPM: fix stack overlay bug that could cause the parent
     process to crash.  [Jeff Trawick]

  *) Unix MPMs: Stop dropping connections when the file descriptor
     is at least FD_SETSIZE.  [Jeff Trawick]

  *) Add core version query function (ap_get_server_revision) and
     accompanying ap_version_t structure (minor MMN bump).
     [André Malo]

  *) mod_rewrite: EOLs sent by external rewritemaps are now consumed
     as whole. That way, on systems with more than one EOL character
     rewritemap programs no longer need to switch stdout to binary
     mode. PR 25635.  [André Malo]

  *) mod_rewrite: Introduce the ability to force a content handler via
     the [handler=...] flag.  [André Malo]

  *) mod_rewrite: Introduce the RewriteCond -x check, which returns
     true if the pattern is a file with execution permissions.
     [André Malo]

  *) mod_ssl: Fix streaming output from an nph- CGI script. PR 21944
     [Joe Orton]

  *) mod_log_config: Fix corruption of buffered logs with threaded
     MPMs.  PR 25520.  [Jeff Trawick]

  *) Build array of allowed methods with proper dimensions, fixing
     possible memory corruption.  [Jeff Trawick]

  *) Allow proxying of resources that are invoked via DirectoryIndex.
     PR 14648.  [André Malo]

  *) mod_rewrite: Allow proxying and RewriteRules in directory context
     for subrequests.  PR 14648, 15114.  [André Malo]

  *) mod_rewrite: Allow setting of any valid HTTP response code.
     PR 25917.  [André Malo]

  *) mod_rewrite: Cookie creation now works locale independent.
     [André Malo]

  *) mod_usertrack no longer inspects the Cookie2 header for
     the cookie name. PR 11475.  [Chris Darrochi <chrisd pearsoncmg.com>]

  *) mod_usertrack no longer overwrites other cookies.
     PR 26002.  [Scott Moore <apache nopdesign.com>]

  *) Make REMOTE_PORT variable available in mod_rewrite.
     PR 25772.  [André Malo]

  *) proxy_http fix: mod_proxy hangs when both KeepAlive and 
     ProxyErrorOverride are enabled, and a non-200 response without a 
     body is generated by the backend server. (e.g.: a client makes a 
     request containing the "If-Modified-Since" and "If-None-Match" 
     headers, to which the backend server respond with status 304.)
     [Graham Wiseman <gwiseman fscinternet.com>, Richard Reiner]
  *) mod_ssl: Add support for distributed session cache using 'distcache'.
     [Geoff Thorpe <geoff geoffthorpe.net>]

  *) mod_dav: Disallow requests with an unescaped hash character in

  *) Add forensic logging module (mod_log_forensic).
     [Ben Laurie]

  *) Fix segfault in mod_mem_cache cache_insert() due to cache size
     becoming negative.  PR: 21285, 21287
     [Bill Stoddard, Massimo Torquati, Jean-Jacques Clar]
  *) mod_proxy with ProxyErrorOverride On in a reverse-proxy configuration attaches
     a body to the 302 response and a wrong Content-Length header. 
     PR: 22951 [Ermanno Scaglione scaglione ..at.. starnetone.de]

  *) Bring ErrorHeader concept forward from 1.3, so that response
     header fields can be set for return even on errors or external
     redirects.  [Ken Coar]

  *) Fix some piped log problems: bogus "piped log program '(null)'
     failed" messages during restart and problem with the logger
     respawning again after Apache is stopped.  PR 21648, PR 24805.
     [Jeff Trawick]

  *) Fix <Limit> and <LimitExcept> parsing to require a closing '>' 
     in the initial container.  PR 25414. 
     [Geoffrey Young <geoff apache.org>]

  *) Clean up httpd -V output: Instead of displaying the MPM source
     directory, display the MPM name and some MPM properties.
     [Geoffrey Young <geoff apache.org>]

  *) Fixed cache-removal order in mod_mem_cache.
     [Jean-Jacques Clar, Cliff Woolley]

     available if the --enable-exception-hook configure parm is used.
     [Jeff Trawick]

  *) mod_ssl/mod_status: Re-enable support for output of SSL session
     cache information in server-status page.  [Joe Orton]

  *) mod_ssl: Remove the shmht session cache, shmcb should be used

     dropped connections.  [Jeff Trawick]

  *) mod_autoindex: new directive IndexStyleSheet 
    [Tyler Riddle <triddle_1999 yahoo.com>, Paul Querna <chip force-elite.com>]

     [Matthieu Estrade <apache moresecurity.org>]
  *) mod_setenvif: Fix the regex optimizer, which under circumstances
     treated the supplied regex as literal string. PR 24219.
     [André Malo]

     filesystem name are rejected with 403.  [Jeff Trawick]

  *) Switch to APR 1.0 API.

  *) Fix mod_include's expression parser to recognize strings correctly
     even if they start with an escaped token.  [André Malo]

  *) Major overhaul of mod_include's filter parser. The new parser code
     is expected to be more robust and should catch all of the edge cases

     that were not handled by the previous one. This includes a binary
     incompatible change of mod_include's external API.  [André Malo]
  *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
     PR 14223.  [André Malo]

  *) mod_rewrite: Catch an edge case, where strange subsequent RewriteRules
     could lead to a 400 (Bad Request) response.  [André Malo]

  *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously
     the current rewrite state was just used as lookup path, which lead to
     strange and often useless results. Related to PR 8493.  [André Malo]

  *) Change Listen directive to bind to all addresses when a hostname is
     not specified.  [Justin Erenkrantz]

  *) Correct failure with Listen directives on machines with IPv6 enabled.

     the ENGINE functions but the engine header files are missing.
     [Cliff Woolley]

  *) mod_rewrite: RewriteRules in server context using the force
     type feature [T=...] no longer disable MultiViews.  [André Malo]

  *) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot.
     [André Malo]

  *) mod_authz_groupfile: Strip trailing spaces of group names. This
     hopefully saves some hours of searching for typos. PR 12863.
     [André Malo]

  *) mod_actions: Propagate the handler name to the action script via
     the REDIRECT_HANDLER environment variable.  [André Malo]

  *) mod_actions: Introduce the "virtual" modifier to the Action directive,
     which allows the use of handlers for virtual locations. PR 8431.
     [André Malo]

  *) mod_speling: Recognize AcceptPathInfo setting for the particular
     location. Default is to reject path information. PR 21059.
