Changes with Apache 2.3.6

  *) mod_log_config: Add the R option to log the handler used within the
     request. [Christian Folini <christian.folini netnea com>]

  *) Allow fine control over the removal of Last-Modified and ETag headers
     within the INCLUDES filter, making it possible to cache responses if
     desired. Fix the default value of the SSIAccessEnable directive.
     [Graham Leggett]

  *) Allow the Define directive to undefine a variable by prefixing the
     argument with a '!'. PR 35350. [Stefan Fritsch]

  *) Make ap_pregsub(), used by AliasMatch and friends, use the same syntax
     for regex backreferences as mod_rewrite and mod_include: Remove the use
     of '&' as an alias for '$0' and allow to escape any character with a
     backslash. PR 48351. [Stefan Fritsch]

  *) mod_authnz_ldap: If AuthLDAPCharsetConfig is set, also convert the
     password to UTF-8. PR 45318.
     [Johannes Müller <joh_m gmx.de>, Stefan Fritsch]

  *) ab: Fix calculation of requests per second in HTML output. PR 48594.
     [Stefan Fritsch]

  *) mod_authnz_ldap: Failures to map a username to a DN, or to check a user
     password now result in an informational level log entry instead of 
     warning level.  [Eric Covener]

Changes with Apache 2.3.5

  *) Ensure each subrequest has a shallow copy of headers_in so that the
     parent request headers are not corrupted.  Elimiates a problematic
     optimization in the case of no request body.  PR 48359 
     [Jake Scott, William Rowe, Ruediger Pluem]

  *) Turn static function get_server_name_for_url() into public
     ap_get_server_name_for_url() and use it where appropriate. This
     fixes mod_rewrite generating invalid URLs for redirects to IPv6
     literal addresses. [Stefan Fritsch]

  *) mod_ldap: Introduce new config option LDAPTimeout to set the timeout
     for LDAP operations like bind and search. [Stefan Fritsch]

  *) mod_proxy, mod_proxy_ftp: Move ProxyFtpDirCharset from mod_proxy to
     mod_proxy_ftp. [Takashi Sato]

  *) mod_proxy, mod_proxy_connect: Move AllowCONNECT from mod_proxy to
     mod_proxy_connect. [Takashi Sato]

  *) mod_cache: Do an exact match of the keys defined by
     CacheIgnoreURLSessionIdentifiers against the querystring instead of
     a partial match.  PR 48401.
     [Dodou Wang <wangdong.08 gmail.com>, Ruediger Pluem]

  *) mod_proxy_balancer: Fix crash in balancer-manager. [Rainer Jung]

  *) Core HTTP: disable keepalive when the Client has sent
     Expect: 100-continue
     but we respond directly with a non-100 response.
     Keepalive here led to data from clients continuing being treated as
     a new request.
     PR 47087 [Nick Kew]

  *) Core: reject NULLs in request line or request headers.
     PR 43039 [Nick Kew]

  *) Core: (re)-introduce -T commandline option to suppress documentroot
     check at startup.
     PR 41887 [Jan van den Berg <janvdberg gmail.com>]

  *) mod_autoindex: support XHTML as equivalent to HTML in IndexOptions,
                    ScanHTMLTitles, ReadmeName, HeaderName
     PR 48416 [Dmitry Bakshaev <dab18 izhnet.ru>, Nick Kew]

  *) Proxy: Fix ProxyPassReverse with relative URL
     Derived (slightly erroneously) from PR 38864 [Nick Kew]

  *) mod_headers: align Header Edit with Header Set when used on Content-Type
     PR 48422 [Cyril Bonté <cyril.bonte free.fr>, Nick Kew>]

  *) mod_headers: Enable multi-match-and-replace edit option
     PR 47066 [Nick Kew]

  *) mod_filter: enable it to act on non-200 responses.
     PR 48377 [Nick Kew]

Changes with Apache 2.3.4

  *) Replace AcceptMutex, LockFile, RewriteLock, SSLMutex, SSLStaplingMutex,
     and WatchdogMutexPath with a single Mutex directive.  Add APIs to
     simplify setup and user customization of APR proc and global mutexes.  
     (See util_mutex.h.)  Build-time setting DEFAULT_LOCKFILE is no longer
     respected; set DEFAULT_REL_RUNTIMEDIR instead.  [Jeff Trawick]

  *) http_core: KeepAlive no longer accepts other than On|Off.
     [Takashi Sato]

  *) mod_dav: Remove errno from dav_error interface.  Calls to dav_new_error()
     and dav_new_error_tag() must be adjusted to add an apr_status_t parameter.
     [Jeff Trawick]

  *) mod_authnz_ldap: Add AuthLDAPBindAuthoritative to allow Authentication to
     try other providers in the case of an LDAP bind failure.
     PR 46608 [Justin Erenkrantz, Joe Schaefer, Tony Stevenson]

  *) Build: fix --with-module to work as documented
     PR 43881 [Gez Saunders <gez.saunders virgin.net>]

     mod_proxy_ftp: NULL pointer dereference on error paths.
     [Stefan Fritsch <sf fritsch.de>, Joe Orton]
  *) mod_ssl: enable support for ECC keys and ECDH ciphers.  Tested against
     OpenSSL 1.0.0b3.  [Vipul Gupta <vipul.gupta sun.com>, Sander Temme]

  *) mod_dav: Include uri when logging a PUT error due to connection abort.
     PR 38149. [Stefan Fritsch]

  *) mod_dav: Return 409 instead of 500 for a LOCK request if the parent
     resource does not exist or is not a collection. PR 43465. [Stefan Fritsch]

  *) mod_dav_fs: Return 409 instead of 500 for Litmus test case copy_nodestcoll
     (a COPY request where the parent of the destination resource does not
     exist). PR 39299. [Stefan Fritsch]

  *) mod_dav_fs: Don't delete the whole file if a PUT with content-range failed.
     PR 42896. [Stefan Fritsch]

  *) mod_dav_fs: Make PUT create files atomically and no longer destroy the
     old file if the transfer aborted. PR 39815. [Paul Querna, Stefan Fritsch]

  *) mod_dav_fs: Remove inode keyed locking as this conflicts with atomically
     creating files. On systems with inode numbers, this is a format change of
     the DavLockDB. The old DavLockDB must be deleted on upgrade.
     [Stefan Fritsch]

  *) mod_log_config: Make ${cookie}C correctly match whole cookie names
     instead of substrings. PR 28037. [Dan Franklin <dan dan-franklin.com>,
     Stefan Fritsch]

  *) vhost: A purely-numeric Host: header should not be treated as a port.
     PR 44979 [Nick Kew]

  *) mod_ldap: Avoid 500 errors with "Unable to set LDAP_OPT_REFHOPLIMIT option to 5"
     when built against openldap by using SDK LDAP_OPT_REFHOPLIMIT defaults unless
     LDAPReferralHopLimit is explicitly configured.
     [Eric Covener]

  *) mod_charset_lite: Honor 'CharsetOptions NoImplicitAdd'.
     [Eric Covener]

  *) mod_ssl: Add support for OCSP Stapling.  PR 43822.  
     [Dr Stephen Henson <shenson oss-institute.org>]

  *) mod_socache_shmcb: Allow parens in file name if cache size is given.
     Fixes SSLSessionCache directive mis-parsing parens in pathname.
     PR 47945. [Stefan Fritsch]

  *) htpasswd: Improve out of disk space handling. PR 30877. [Stefan Fritsch]

  *) htpasswd: Use MD5 hash by default on all platforms. [Stefan Fritsch]

  *) mod_sed: Reduce memory consumption when processing very long lines.
     PR 48024 [Basant Kumar Kukreja <basant.kukreja sun.com>]

     PR 47178. [Philipp Hagemeister <oss phihag.de>]

  *) Allow ProxyPreserveHost to work in <Proxy> sections. PR 34901.
     [Stefan Fritsch]

  *) configure: Fix THREADED_MPMS so that mod_cgid is enabled again 
     for worker MPM. [Takashi Sato]

  *) mod_dav: Provide a mechanism to obtain the request_rec and pathname
     from the dav_resource. [Jari Urpalainen <jari.urpalainen nokia.com>,
     Brian France <brian brianfrance.com>]

     modules to avoid segmentation fault. PR 47951. [hirose31 gmail.com]

  *) mod_cache: correctly consider s-maxage in cacheability
     decisions.  [Dan Poirier]

  *) mod_logio/core: Report more accurate byte counts in mod_status if
     mod_logio is loaded. PR 25656. [Stefan Fritsch]

  *) mod_ldap: If LDAPSharedCacheSize is too small, try harder to purge
     some cache entries and log a warning. Also increase the default
     LDAPSharedCacheSize to 500000. This is a more realistic size suitable
     for the default values of 1024 for LdapCacheEntries/LdapOpCacheEntries.
