+Changes with Apache 2.3.13
+
+ *) mod_ext_filter: Remove DebugLevel option in favor of per-module loglevel.
+ [Stefan Fritsch]
+
+ *) mod_include: Make the "#if expr" element use the new "ap_expr" expression
+ parser. The old parser can still be used by setting the new directive
+ SSILegacyExprParser. [Stefan Fritsch]
+
+ *) core: Add some features to ap_expr for use by mod_include: a restricted
+ mode that does not allow to bypass request access restrictions; new
+ variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an
+ alias for -U; an additional data entry in ap_expr_eval_ctx_t for use by
+ the consumer; an extensible ap_expr_exec_ctx() API that allows to use that
+ data entry. [Stefan Fritsch]
+
+ *) mod_include: Merge directory configs instead of one SSI* config directive
+ causing all other per-directory SSI* config directives to be reset.
+ [Stefan Fritsch]
+
+ *) mod_charset_lite: Remove DebugLevel option in favour of per-module
+ loglevel. [Stefan Fritsch]
+
+ *) core: Add ap_regexec_len() function that works with non-null-terminated
+ strings. PR 51231. [Yehezkel Horowitz <horowity checkpoint com>]
+
+ *) mod_authnz_ldap: If the LDAP server returns constraint violation,
+ don't treat this as an error but as "auth denied". [Stefan Fritsch]
+
+ *) mod_proxy_fcgi|scgi: Add support for "best guess" of PATH_INFO
+ for SCGI/FCGI. PR 50880, 50851. [Mark Montague <mark catseye.org>,
+ Jim Jagielski]
+
+ *) mod_cache: When content is served stale, and there is no means to
+ revalidate the content using ETag or Last-Modified, and we have
+ mandated no stale-on-error behaviour, stand down and don't cache.
+ Saves a cache write that will never be read.
+ [Graham Leggett]
+
+ *) mod_reqtimeout: Fix a timed out connection going into the keep-alive
+ state after a timeout when discarding a request body. PR 51103.
+ [Stefan Fritsch]
+
+ *) core: Add various file existance test operators to ap_expr.
+ [Stefan Fritsch]
+
+ *) mod_proxy_express: New mass reverse-proxy switch extension for
+ mod_proxy. [Jim Jagielski]
+
+ *) configure: Fix script error when configuring module set "reallyall".
+ [Rainer Jung]
+
+Changes with Apache 2.3.12
+
+ *) configure, core: Provide easier support for APR's hook probe
+ capability. [Jim Jagielski, Jeff Trawick]
+
+ *) Silence autoconf 2.68 warnings. [Rainer Jung]
+
+ *) mod_authnz_ldap: Resolve crash when LDAP is used for authorization only
+ [Scott Hill <shill genscape.com>]
+
+ *) support: Make sure check_forensic works with mod_unique_id loaded
+ [Joe Schaefer]
+
+ *) Add child_status hook for tracking creation/termination of MPM child
+ processes. Add end_generation hook for notification when the last
+ MPM child of a generation exits. [Jeff Trawick]
+
+ *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
+ process as opposed to disabling caching completely. This allows to use
+ the non-shared-memory cache as a workaround for the shared memory cache
+ not being available during graceful restarts. PR 48958. [Stefan Fritsch]
+
+ *) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,
+ necessary if a module (like mod_perl) registers additional modules late
+ in the startup phase. [Stefan Fritsch]
+
+ *) core: Prevent segfault if DYNAMIC_MODULE_LIMIT is reached. PR 51072.
+ [Torsten Förtsch <torsten foertsch gmx net>]
+
+ *) WinNT MPM: Improve robustness under heavy load. [Jeff Trawick]
+
+ *) MinGW build improvements. PR 49535. [John Vandenberg
+ <jayvdb gmail.com>, Jeff Trawick]
+
+ *) core: Support module names with colons in loglevel configuration.
+ [Torsten Förtsch <torsten foertsch gmx net>]
+
+ *) mod_ssl, ab: Support OpenSSL compiled without SSLv2 support.
+ [Stefan Fritsch]
+
+ *) core: Abort if the MPM is changed across restart. [Jeff Trawick]
+
+ *) mod_proxy_ajp: Add support for 'ProxyErrorOverride on'. PR 50945.
+ [Peter Pramberger <peter pramberger.at>, Jim Jagielski]
+
+ *) mod_proxy_fcgi: Add support for 'ProxyErrorOverride on'. PR 50913.
+ [Mark Montague <mark catseye.org>, Jim Jagielski]
+
+ *) core: Change the APIs of ap_cfg_getline() and ap_cfg_getc() to return an
+ error code. Abort with a nice error message if a config line is too long.
+ Partial fix for PR 50824. [Stefan Fritsch]
+
+ *) mod_info: Dump config to stdout during startup if -DDUMP_CONFIG is
+ specified. PR 31956. [Stefan Fritsch]
+
+ *) Restore visibility of DEFAULT_PIDLOG to core and modules. MPM
+ helper function ap_remove_pid() added. [Jeff Trawick]
+
+ *) Enable DEFAULT_REL_RUNTIMEDIR on Windows and NetWare. [various]
+
+ *) Correct C++ incompatibility with http_log.h. [Stefan Fritsch, Jeff
+ Trawick]
+
+ *) mod_log_config: Prevent segfault. PR 50861. [Torsten Förtsch
+ <torsten.foertsch gmx.net>]
+
+ *) core: AllowEncodedSlashes new option NoDecode to allow encoded slashes
+ in request URL path info but not decode them. Change behavior of option
+ "On" to decode the encoded slashes as 2.0 and 2.2 do. PR 35256,
+ PR 46830. [Dan Poirier]
+
+ *) mod_ssl: Check SNI hostname against Host header case-insensitively.
+ PR 49491. [Mayank Agrawal <magrawal.08 gmail.com>]
+
+ *) mod_ldap: Add LDAPConnectionPoolTTL to give control over lifetime
+ of bound backend LDAP connections. PR47634 [Eric Covener]
+
+ *) mod_cache: Make CacheEnable and CacheDisable configurable per
+ directory in addition to per server, making them work from within
+ a LocationMatch. [Graham Leggett]
+
+ *) worker, event, prefork: Correct several issues when built as
+ DSOs; most notably, the scoreboard was reinitialized during graceful
+ restart, such that processes of the previous generation were not
+ observable. [Jeff Trawick]
