     [Christophe Jaillet]

  *) mod_cgid: Within the first minute of a server start or restart, 
     allow mod_cgid to retry connecting to its daemon process. Previously,
     'No such file or directory: unable to connect to cgi daemon...' could
     be logged without an actual retry. PR57685. 
     [Edward Lu <Chaosed0 gmail.com>]
  *) mod_proxy: Use the original (non absolute) form of the request-line's URI
     for requests embedded in CONNECT payloads used to connect SSL backends via
     a ProxyRemote forward-proxy.  PR 55892.  [Hendrik Harms <hendrik.harms
     gmail com>, William Rowe, Yann Ylavic]

     response status (finally logged) when nothing is to be done. PR 56035.
     [Yann Ylavic]
  *) mod_proxy_connect/wstunnel: If both client and backend sides get readable
     at the same time, don't lose errors occurring while forwarding on the first
     side when none occurs next on the other side, and abort.  [Yann Ylavic]

  *) mod_rewrite: Improve relative substitutions in per-directory/htaccess
     context for directories found by mod_userdir and mod_alias.  These no
     longer require RewriteBase to be specified. [Eric Covener]

  *) mod_proxy_http: Don't expect the backend to ack the "Connection: close" to
     finally close those not meant to be kept alive by SetEnv proxy-nokeepalive
     or force-proxy-request-1.0.  [Yann Ylavic]

  *) core: If explicitly configured, use the KeepaliveTimeout value of the
     virtual host which handled the latest request on the connection, or by
     default the one of the first virtual host bound to the same IP:port.

     a combination of certificate serialNumber and issuer as defined by
     CertificateExactMatch in RFC4523. [Graham Leggett]

     sized 664 byte array per merge to a hash table. [Graham Leggett]

     Yann Ylavic]

  *) mpm_event: Avoid access to the scoreboard from the connection while
     it is suspended (waiting for events).  [Eric Covener, Jeff Trawick]

  *) mod_ssl: Fix renegotiation failures redirected to an ErrorDocument.
     PR 57334.  [Yann Ylavic].

  *) mod_proxy_ajp: Forward SSL protocol name (SSLv3, TLSv1.1 etc.) as a
     request attribute to the backend. Recent Tomcat versions will extract
     it and provide it as a servlet request attribute named
     "org.apache.tomcat.util.net.secure_protocol_version". [Rainer Jung]

  *) 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]

  *) 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]
