Changes with Apache 2.3.0
  [Remove entries to the current 2.0 and 2.2 section below, when backported]

  *) Worker MPM: On graceless shutdown or restart, send signals to
     each worker thread to wake them up if they're polling on a
     Keep-Alive connection.  PR 38737.  [Chris Darroch]

  *) Worker and event MPMs: Remove improper scoreboard updates which were
     performed in the event of a fork() failure.  [Chris Darroch]

  *) mod_cache: Make caching of reverse SSL proxies possible again. PR 39593.
     [Ruediger Pluem, Joe Orton]

  *) Add support for fcgi:// proxies to mod_rewrite.
     [Markus Schiegl <ms schiegl.com>]

  *) Remove incorrect comments from scoreboard.h regarding conditional
     loading of worker_score structure with mod_status, and remove unused
     definitions relating to old life_status field.
     [Chris Darroch <chrisd pearsoncmg.com>]

  *) Remove allocation of memory for unused array of lb_score pointers
     in ap_init_scoreboard().  [Chris Darroch <chrisd pearsoncmg.com>]

  *) core, mod_http: add optional 'scheme://' prefix to ServerName directive. 
     For 'https', mod_http returns "https" for the ap_hook_http_scheme and
     DEFAULT_HTTPS_PORT for ap_hook_default_port.  This fixes Redirect
     responses to requests for directories without a trailing slash when
     httpd runs behind a proxy or offload device that processes SSL.  It
     also enables support for Subversion in that configuration.  This change is 
     completely backwards compatible and passes the perl-framework.  Minor
     mmn bump because I add a field to server_rec.  [Sander Temme]     

  *) mod_mem_cache: Set content type correctly when delivering data from
     cache. PR 39266. [Ruediger Pluem]

  *) worker and event MPMs: fix excessive forking if fork() or child_init 
     take a long time.  PR 39275.
     [Greg Ames, Jeff Trawick, Chris Darroch <chrisd pearsoncmg.com> ]

  *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
     [Garrett Rooney, Jim Jagielski, Paul Querna]

  *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
     [Chris Darroch <chrisd pearsoncmg.com>]

  *) mod_charset_lite: Remove Content-Length when output filter can 
     invalidate it.  Warn when input filter can invalidate it.
     [Jeff Trawick]

  *) mod_ssl: Fix spurious hostname mismatch warning for valid
     wildcard certificates.  PR 37911.  [Nick Burch <nick torchbox.com>]

  *) Respect GracefulShutdownTimeout in the worker and event MPMs.
     [Chris Darroch <chrisd pearsoncmg.com>, Garrett Rooney]

  *) Authz: Add the new module mod_authn_core that will provide common
     authn directives such as 'AuthType', 'AuthName'.  Move the directives
     'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias 
     into mod_authn_core. [Brad Nicholes]

  *) Authz: Mark the directives 'Order', 'Allow', 'Deny' and 'Satisfy' as 
     deprecated and move them into the new module mod_access_compat which
     can be loaded to provide backwards compatibility for these directives.
     [Brad Nicholes]

  *) Authz: Move the 'Require' directive from the core module as well as 
     add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>' 
     and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR' 
     logic into the authorization processing. [Brad Nicholes]

  *) Authz: Add the new module mod_authz_core which acts as the 
     authorization provider vector and contains common authz 
     directives. [Brad Nicholes]

  *) Authz: Renamed mod_authz_dbm authz providers from 'group' and 
     'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]

  *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
     host-based access control provided by mod_authz_host and invoked 
     through the 'Require' directive. [Brad Nicholes]

  *) Authz: Convert all of the authz modules from hook based to 
     provider based. [Brad Nicholes]

  *) mod_cache: Add CacheMinExpire directive to set the minimum time in
     seconds to cache a document.
     [Brian Akins <brian.akins turner.com>, Ruediger Pluem]

  *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]

  *) Fix typo in ProxyStatus syntax error message.
     [Christophe Jaillet <christophe.jaillet wanadoo.fr>]

  *) Asynchronous write completion for the Event MPM.  [Brian Pane]

  *) Added an End-Of-Request bucket type.  The logging of a request and
     the freeing of its pool are now done when the EOR bucket is destroyed.
     This has the effect of delaying the logging until right after the last
     of the response is sent; ap_core_output_filter() calls the access logger
     indirectly when it destroys the EOR bucket.  [Brian Pane]

  *) Rewrite of logresolve support utility: IPv6 addresses are now supported
     and the format of statistical output has changed. [Colm MacCarthaigh]

  *) Rewrite of ap_coreoutput_filter to do nonblocking writes  [Brian Pane]

  *) Added new connection states for handler and write completion
     [Brian Pane]

  *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs.  PR 34264.
     [Justin Erenkrantz]

  *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
     allowing string-valued client certificate attributes to be used for
     access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
     [Martin Kraemer, David Reid]

Changes with Apache 2.2.3


Changes with Apache 2.2.2

  *) mod_deflate: Allow mod_deflate to handle internal redirects.
     [Brian J. France <list firehawksystems.com>]

  *) mod_proxy_balancer: Initialize members of a balancer correctly.
     PR 38227. [James A. Robinson <jim.robinson stanford.edu>]

  *) mod_proxy: Do not release connections from connection pool twice.
     PR 38793. [Ruediger Pluem, matthias <mk-asf gigacodes.de>]

  *) core: Prevent reading uninitialized memory while reading a line of
     protocol input.  PR 39282. [Davi Arnaut <davi haxent.com.br>]

  *) mod_dbd: Update defaults, improve error reporting.
     [Chris Darroch <chrisd pearsoncmg com>, Nick Kew]

  *) mod_dbd: Create own pool and mutex to avoid problem use of
     process pool in request processing.
     [Chris Darroch <chrisd pearsoncmg com>]

  *) HTML-escape the Expect error message.  Not classed as security as
     an attacker has no way to influence the Expect header a victim will
     send to a target site.  Reported by Thiago Zaninotti
     <thiango nstalker.com>. [Mark Cox]

  *) htdbm: Fix crash processing -d option in 64-bit mode on HP-UX.
     [Jeff Trawick]

  *) htdbm: Warn the user when adding a plaintext password on a platform
     where it wouldn't work with the server (i.e., anywhere that has
     crypt()).  [Jeff Trawick]

  *) mod_proxy: don't reuse a connection that may be to the wrong backend
     PR 39253 [Ruediger Pluem]

  *) Default handler: Don't return output filter apr_status_t values.
     PR 31759.  [Jeff Trawick, Ruediger Pluem, Joe Orton]

Changes with Apache 2.2.1

  *) SECURITY: CVE-2005-3357 (cve.mitre.org)
     mod_ssl: Fix a possible crash during access control checks if a
     non-SSL request is processed for an SSL vhost (such as the
     "HTTP request received on SSL port" error message when an 400 
     ErrorDocument is configured, or if using "SSLEngine optional").
     PR 37791.  [Rüdiger Plüm, Joe Orton]

  *) SECURITY: CVE-2005-3352 (cve.mitre.org)
     mod_imagemap: Escape untrusted referer header before outputting
     in HTML to avoid potential cross-site scripting.  Change also
     made to ap_escape_html so we escape quotes.  Reported by JPCERT.
     [Mark Cox]

  *) mod_proxy_ajp: Flushing of the output after each AJP chunk is now
     configurable at runtime via the 'flushpackets' and 'flushwait' worker
     params. Minor MMN bump. [Jim Jagielski]

  *) mod_proxy: Fix incorrect usage of local and shared worker init.
     PR 38403. [Jim Jagielski]

  *) mod_isapi: Fix compiler errors on Unix platforms.
     [William Rowe]

     [Rüdiger Plüm, Joe Orton]

  *) mod_disk_cache: Return the correct error codes from bucket read
     failures, instead of APR_EGENERAL.
     [Brian Akins <brian.akins turner.com>]

  *) Add APR/APR-Util Compiled and Runtime Version numbers to the
     output of 'httpd -V'. [William Rowe]

  *) http: If a connection is aborted while waiting for a chunked line,
     flag the connection as errored out.  [Justin Erenkrantz]

  *) core: Reject invalid Expect header immediately. PR 38123.
