  [Remove entries to the current 2.0 and 2.2 section below, when backported]
  *) mod_proxy_ajp: Added cping/cpong support for the AJP protocol.
     A new worker directive ping=timeout will cause CPING packet
     to be send expecting CPONG packet within defined timeout.
     In case the backend is too busy this will fail instead
     sending the full header.  [Mladen Turk]

  *) mod_dbd: Fix dependence on virtualhost configuration in
     defining prepared statements (possible segfault at startup
     in user modules such as mod_authn_dbd).  [Nick Kew]

  *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
     to circumvent the symbolic link checks imposed by FollowSymLinks and
     SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]

  *) mod_proxy: Support environment variable interpolation in reverse
     proxying directives [Nick Kew]

  *) mod_proxy_balancer: Workers can now be defined as "hot standby" which
     will only be used if all other workers are unusable (eg: in
     error or disabled). Also, the balancer-manager displays the election
     count and I/O counts of all workers. [Jim Jagielski]

  *) core: Add the filename of the configuration file to the warning message
     about the useless use of AllowOverride. PR 39992.
     [Darryl Miles <darryl darrylmiles.org>]

  *) mod_proxy_balancer: Retry worker chosen by route / redirect worker if
     it is in error state before sending "Service Temporarily Unavailable".
     PR 38962. [Christian Boitel <cboitel lfdj.com>]

  *) mod_proxy_balancer: Add information about the route, the sticky session
     and the worker used during a request as environment variables. PR 39806.
     [Brian <brectanu gmail.com>]

  *) mod_isapi: Handle "HTTP/1.1 200 OK" style status lines correctly, the
     token parser worked while the resulting length was misinterpreted.

  *) mod_isapi: Return 0 (failure) for more of the various ap_pass_brigade
     attempts to stream the response at the client.  PR 30022 [William Rowe]

  *) mod_isapi: Ensure we walk through all the methods the developer may have
     employed to report their HTTP status result code.

  *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
     configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
     The default is none as this is far greater debugging resolution than 
     the typical administrator is prepared to untangle.  [William Rowe]

  *) mod_speling: Add directive to deal with case corrections only
     and ignore other misspellings [Olivier Thereaux  <ot w3.org>]

  *) mod_disk_cache: If possible, check if the size of an object to cache is
     within the configured boundaries before actually saving data.
     [Niklas Edmundsson <nikke acc.umu.se>]

  *) mod_cache: Convert all values to seconds before comparing them when
     checking whether to send a Warning header for a stale response.
     PR 39713. [Owen Taylor <otaylor redhat.com>]

  *) mod_authnz_ldap: Fix a problem with invalid auth error detection for
     LDAP client SDKs that don't support LDAP_SECURITY_ERROR macro. PR 39529.
     [Ray Price <dohrayme yahoo.com>, Josh Fenlason <jfenlason ptc.com>]
  *) mod_cache: Do not overwrite the Content-Type in the cache, for
     successfully revalidated cached objects. PR 39647. [Ruediger Pluem]

  *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
     final name. [Davi Arnaut <davi haxent.com.br>]

  *) 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]     

  *) 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>]

  *) 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

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

  *) Respect GracefulShutdownTimeout in the worker and event MPMs.
     [Chris Darroch, Garrett Rooney]

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

  *) mod_autoindex: Fix filename escaping with FancyIndexing disabled.
     PR 38910.  [Robby Griffin <rmg terc.edu>]

  *) mod_charset_lite: Bypass translation when the source and dest charsets
     are the same. [Jeff Trawick]
