Changes with Apache 2.3.7

  *) Proxy: get the headers right in a HEAD request with
     ProxyErrorOverride, by checking for an overridden error
     before not after going into a catch-all code path.
     PR 41646.
     Patch by Nick Kew, based on detailed analysis by Stuart Children.

  *) support/rotatelogs: Support the simplest log rotation case, log
     truncation. Useful when the log is being processed in real time
     using a command like tail. [Graham Leggett]

  *) support/htcacheclean: Teach it how to write a pid file (modelled on
     httpd's writing of a pid file) so that it becomes possible to run
     more than one instance of htcacheclean on the same machine.
     [Graham Leggett]

  *) Log command line on startup, so there's a record of command line
     arguments like -f.
     PR 48752.  [Dan Poirier]

  *) Introduce mod_reflector, a handler capable of reflecting POSTed
     request bodies back within the response through the output filter
     stack. Can be used to turn an output filter into a web service.
     [Graham Leggett]

  *) mod_proxy_http: Make sure that when an ErrorDocument is served
     from a reverse proxied URL, that the subrequest respects the status
     of the original request. This brings the behaviour of proxy_handler
     in line with default_handler. PR 47106. [Graham Leggett]

  *) Support wildcards in both the directory and file components of
     the path specified by the Include directive. [Graham Leggett]

  *) mod_proxy, mod_proxy_http: Support remote https proxies
     by using HTTP CONNECT.
     PR 19188.  [Philippe Dutrueux <lilas evidian.com>, Rainer Jung]

Changes with Apache 2.3.6

  *) worker: Don't report server has reached MaxClients until it has.
     Add message when server gets within MinSpareThreads of MaxClients.
     PR 46996.  [Dan Poirier]

  *) mod_session: Session expiry was being initialised, but not updated
     on each session save, resulting in timed out sessions when there
     should not have been. Fixed. [Graham Leggett]

  *) 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]

  *) Add new UnDefine directive to undefine a variable. 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>]

Changes with Apache 2.3.3

  *) SECURITY: CVE-2009-3095 (cve.mitre.org)
     mod_proxy_ftp: sanity check authn credentials.
     [Stefan Fritsch <sf fritsch.de>, Joe Orton]

  *) SECURITY: CVE-2009-3094 (cve.mitre.org)
     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.
