Changes with Apache 2.4.12

  *) mpm_winnt: Accept utf-8 (Unicode) service names and descriptions for

  *) mpm_winnt: Normalize the error and status messages emitted by service.c,
     the service control interface for Windows.  [William Rowe]

Changes with Apache 2.4.11
 
  *) SECURITY: CVE-2014-3583 (cve.mitre.org)
     mod_proxy_fcgi: Fix a potential crash due to buffer over-read, with
     response headers' size above 8K.  [Yann Ylavic, Jeff Trawick]

  *) SECURITY: CVE-2014-3581 (cve.mitre.org)
     mod_cache: Avoid a crash when Content-Type has an empty value.
     PR 56924.  [Mark Montague <mark catseye.org>, Jan Kaluza]

  *) SECURITY: CVE-2014-8109 (cve.mitre.org)
     mod_lua: Fix handling of the Require line when a LuaAuthzProvider is
     used in multiple Require directives with different arguments.
     PR57204 [Edward Lu <Chaosed0 gmail.com>]

  *) SECURITY: CVE-2013-5704 (cve.mitre.org)
     core: HTTP trailers could be used to replace HTTP headers
     late during request processing, potentially undoing or
     otherwise confusing modules that examined or modified
     request headers earlier.  Adds "MergeTrailers" directive to restore
     legacy behavior.  [Edward Lu, Yann Ylavic, Joe Orton, Eric Covener]

  *) mod_ssl: New directive SSLSessionTickets (On|Off).
     The directive controls the use of TLS session tickets (RFC 5077),
     default value is "On" (unchanged behavior).
     Session ticket creation uses a random key created during web
     server startup and recreated during restarts. No other key
     recreation mechanism is available currently. Therefore using session
     tickets without restarting the web server with an appropriate frequency
     (e.g. daily) compromises perfect forward secrecy. [Rainer Jung]

  *) mod_proxy_fcgi: Provide some basic alternate options for specifying
     how PATH_INFO is passed to FastCGI backends by adding significance to
     the value of proxy-fcgi-pathinfo. PR 55329. [Eric Covener]
 
  *) mod_proxy_fcgi: Enable UDS backends configured with SetHandler/RewriteRule
     to opt-in to connection reuse and other Proxy options via explicitly
     declared "proxy workers" (<Proxy unix:... enablereuse=on max=...)
     [Eric Covener]

  *) mod_proxy: Add "enablereuse" option as the inverse of "disablereuse".
     [Eric Covener]

  *) mod_proxy_fcgi: Enable opt-in to TCP connection reuse by explicitly
     setting proxy option disablereuse=off. [Eric Covener] PR 57378.

  *) event: Update the internal "connection id" when requests
     move from thread to thread. Reuse can confuse modules like
     mod_cgid. PR 57435. [Michael Thorpe <mike gistnet.com>]

  *) mod_proxy_fcgi: Remove proxy:balancer:// prefix from SCRIPT_FILENAME
     passed to fastcgi backends. [Eric Covener]

  *) core: Configuration files with long lines and continuation characters
     are not read properly. PR 55910. [Manuel Mausz <manuel-as mausz.at>]

  *) mod_include: the 'env' function was incorrectly handled as 'getenv' if the
     leading 'e' was written in upper case in <!--#if expr="..." -->
     statements. [Christophe Jaillet]

  *) split-logfile: Fix perl error:  'Can't use string ("example.org:80")
     as a symbol ref while "strict refs"'. PR 56329.
     [Holger Mauermann <mauermann gmail.com>]

  *) mod_proxy: Prevent ProxyPassReverse from doing a substitution when
     the URL parameter interpolates to an empty string. PR 56603.
     [<ajprout hotmail.com>]

  *) core: Fix -D[efined] or <Define>[d] variables lifetime accross restarts.
     PR 57328.  [Armin Abfalterer <a.abfalterer gmail.com>, Yann Ylavic].

     from the ones to be forwarded to the backend. PR 45387.
     [Yann Ylavic]

     like reads (level TRACE4). [Yann Ylavic]

  *) mod_proxy_fcgi: Ignore body data from backend for 304 responses. PR 57198.
     [Jan Kaluza]

  *) mod_ssl: Do not crash when looking up SSL related variables during
     expression evaluation on non SSL connections. PR 57070  [Ruediger Pluem]

  *) mod_proxy_ajp: Fix handling of the default port (8009) in the
     ProxyPass and <Proxy> configurations.  PR 57259.  [Yann Ylavic]

  *) mpm_event: Avoid a possible use after free when notifying the end of
     connection during lingering close.  PR 57268.  [Eric Covener, Yann Ylavic]

  *) mod_ssl: Fix recognition of OCSP stapling responses that are encoded
     improperly or too large.  [Jeff Trawick]

  *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers.
     [Jeff Trawick]

     further processing.  [Yann Ylavic]

  *) mod_proxy_connect: Fix ProxyRemote to https:// backends on EBCDIC
     systems. PR 57092 [Edward Lu <Chaosed0 gmail.com>]

  *) mod_cache: Avoid a 304 response to an unconditional requst when an AH00752
     CacheLock error occurs during cache revalidation. [Eric Covener]
 
  *) mod_ssl: Move OCSP stapling information from a per-certificate store to
     a per-server hash. PR 54357, PR 56919. [Alex Bligh <alex alex.org.uk>,
     Yann Ylavic, Kaspar Brand]

  *) mod_ratelimit: Drop severity of AH01455 and AH01457 (ap_pass_brigade
