  [Remove entries to the current 2.0 and 2.2 section below, when backported]
  *) HTTP proxy ProxyErrorOverride: Leave 1xx and 3xx responses alone.  Only
     processing of error responses (4xx, 5xx) will be altered.  PR 39245.
     [Jeff Trawick, Bart van der Schans <schans hippo.nl>]

  *) htdbm: Enable crypt support on platforms with crypt() but not
     <crypt.h>, such as z/OS. [David Jones <oscaremma gmail.com>]

  *) mod_ssl: initialize thread locks before initializing the hardware
     acceleration library, so the latter can make use of the former. 
     PR 20951. [adunn at ncipher.com, reviewed by Sander Temme]

  *) mod_so: Solve dev's confusion by reporting expected/seen module
     magic signatures when failing with a 'garbled' message, and solve
     user's confusion by pointing out 'perhaps compiled for a different
     version of apache?'.  [William Rowe]

  *) mod_ssl: Version reporting update; displays 'compiled against'
     Apache and build-time SSL Library versions at loglevel [info],
     while reporting the run-time SSL Library version in the server
     info tags.  Helps to identify a mod_ssl built against one flavor
     of OpenSSL but running against another (also adds SSL-C version
     number reporting.)  [William Rowe]

  *) core: Change etag generation to produce identical results on 
     32-bit and 64-bit platforms.  PR 40064.  [Joe Orton]

  *) ab: Add -r option to continue after socket receive errors. 
     [Filip Hanik <devlist hanik.com>]

  *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
     for SDKs that define LDAP_NO_LIMIT to something other than -1.
     [David Jones <oscaremma gmail.com>]

  *) mod_cache: Use the same cache key throughout the whole request processing
     to handle escaped URLs correctly.  PR 41475. [Ruediger Pluem]

  *) mod_cache: Add CacheIgnoreQueryString directive.  PR 41484.
     [Fredrik Widlund <fredrik.widlund qbrick.com>]

  *) mod_dbd: Introduce configuration groups to allow inheritance by virtual
     hosts of database configurations from the main server.  Determine the
     minimal set of distinct configurations and share connection pools
     whenever possible.  Allow virtual hosts to override inherited SQL
     statements.  PR 41302.  [Chris Darroch]
  *) core: Fix broken chunk filtering that causes all non blocking reads to be
     converted into blocking reads.  PR 41056. [Jean-Frederic Clere, Jim Jagielski]

  *) apxs: Enhance -q flag to print all known variables and their values
     when invoked without variable name(s). 
     [William Rowe, Sander Temme]

  *) mod_dbd: Create memory sub-pools for each DB connection and close
     DB connections in a pool cleanup function.  Ensure prepared statements
     are destroyed before DB connection is closed.  When using reslists,
     prevent segfaults when child processes exit, and stop memory leakage
     of ap_dbd_t structures.  Avoid use of global s->process->pool, which
     isn't destroyed by exiting child processes in most multi-process MPMs.
     PR 39985.  [Chris Darroch, Nick Kew]

  *) apxs: Eliminate run-time check for mod_so.  PR 40653.
     [David M. Lee <dmlee crossroads.com>]

  *) beos MPM: Create pmain pool and run modules' child_init hooks when
     entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
     [Chris Darroch]

  *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
     cleanups registered in modules' child_init hooks are performed.
     [Chris Darroch]

  *) mod_dbd: Handle error conditions in dbd_construct() properly.
     Simplify ap_dbd_open() and use correct arguments to apr_dbd_error()
     when non-threaded.  Register correct cleanup data in non-threaded
     ap_dbd_acquire() and ap_dbd_cacquire().  Clean up configuration data
     and merge function.  Use ap_log_error() wherever possible.
     [Chris Darroch, Nick Kew]

  *) core: Do not replace a Date header set by a proxied backend server.
     PR 40232. [Ruediger Pluem]

  *) mod_proxy: Ensure that at least scheme://hostname[:port] matches between
     worker and URL when searching for the best fitting worker for a given URL.
     PR 40910. [Ruediger Pluem]

  *) mod_cache: Remove expired content from cache that cannot be revalidated.
     PR 30370. [Ruediger Pluem]

  *) mod_dbd: Stash DBD connections in request_config of initial request
     only, or else sub-requests and internal redirections may cause
     entire DBD pool to be stashed in a single HTTP request.  [Chris Darroch]

  *) mod_cache: Correctly cache objects whose URL query string has been
     modified by mod_rewrite. PR 40805. [Ruediger Pluem]

  *) mod_proxy: Add a missing assignment in an error checking code path.
     PR 40865. [Andrew Rucker Jones <arjones simultan.dyndns.org>]

  *) mod_mem_cache: Increase the minimum and default value for
     MCacheMinObjectSize from 0 to 1, as a MCacheMinObjectSize of 0 does not
     make sense and leads to a division by zero.  PR 40576.
     [Xuekun Hu <xuekun.hu gmail.com>]

  *) Fix issue which could cause error messages to be written to access logs
     on Win32.  PR 40476.  [Tom Donovan <Tom.Donovan acm.org>]

  *) The LockFile directive, which specifies the location of
     the accept() mutex lockfile, is deprecated. Instead, the
     AcceptMutex directive now takes an optional lockfile
     location parameter, ala SSLMutex. [Jim Jagielski]

  *) mod_authn_dbd: Export any additional columns queried in the SQL select
     into the environment with the name AUTHENTICATE_<COLUMN>. This brings
     mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]

  *) mod_dbd: Key the storage of prepared statements on the hex string
     value of server_rec, rather than the server name, as the server name
     may change (eg when the server name is set) at any time, causing
     weird behaviour in modules dependent on mod_dbd. [Graham Leggett]

  *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]

  *) sendfile_nonblocking() takes the _brigade_ as an argument, gets 
     the first bucket from the brigade, finds it not to be a FILE
     bucket and barfs. The fix is to pass a bucket rather than a brigade.
     [Niklas Edmundsson <nikke acc.umu.se>]

  *) mod_rewrite: support rewritemap by SQL query [Nick Kew]

  *) mod_proxy: Print the correct error message for erroneous configured
     ProxyPass directives. PR 40439. [serai lans-tv.com]

  *) ap_get_server_version() has been removed.  Third-party modules must 
     now use ap_get_server_banner() or ap_get_server_description().
     [Jeff Trawick]
  *) All MPMs: Introduce a check_config phase between pre_config and
     open_logs, to allow modules to review interdependent configuration
     directive values and adjust them while messages can still be logged
     to the console.  Handle relevant MPM directives during this phase
     and format messages for both the console and the error log, as
     appropriate.  [Chris Darroch]

  *) mod_proxy: don't URLencode tilde in path component
     [Stijn Hoop <stijn sandcat.nl>]

  *) mpm_winnt: Fix return values from wait_for_many_objects.
     The return value is index to the signaled thread in the
     creted_threads array. We can not use WAIT_TIMEOUT because
     his value is defined as 258, thus limiting the MaxThreads
     to that value. [Mladen Turk]

  *) mod_cache: While serving a cached entity ensure that filters that have
     been applied to this cached entity before saving it to the cache are not
     applied again. PR 40090. [Ruediger Pluem]

  *) 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]
  *) 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>]

  *) 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_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_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]

  *) 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>]
