CHANGES

     SymlinksIfOwnerMatch are set [Nick Kew]

  *) core: fix origin checking in SymlinksIfOwnerMatch
     PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]

  *) Activate mod_cache, mod_file_cache and mod_disk_cache as part of the
     'most' set for '--enable-modules' and '--enable-shared-mods'. Include
     mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]

  *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
     contain public function declarations which are useful for
     third party module authors. PR 42431 [Dirk-Willem van Gulik].

  *) mod_dir, mod_negotiation: pass the output filter information
     to newly created sub requests; as these are later on used
     as true requests with an internal redirect. This allows for
     mod_cache et.al. to trap the results of the redirect.
     [Dirk-Willem van Gulik, Ruediger Pluem]

  *) mod_ldap: Add support (taking advantage of the new APR capability)
     for ldap rebind callback while chasing referrals. This allows direct
     searches on LDAP servers (in particular MS Active Directory 2003+)
     using referrals without the use of the global catalog.
     PRs 26538, 40268, and 42557 [Paul J. Reder]

  *) ApacheMonitor.exe: Introduce --kill argument for use by the
     installer.  This will permit the installation tool to remove
     all running instances before attempting to remove the .exe.
     [William Rowe]

  *) mod_ssl: Add support for OCSP validation of client certificates.
     PR 41123.  [Marc Stern <marc.stern approach.be>, Joe Orton]

  *) mod_serf: New module for Reverse Proxying. [Paul Querna]

  *) core: Add the option to keep aside a request body up to a certain
     size that would otherwise be discarded, to be consumed by filters
     such as mod_include. When enabled for a directory, POST requests
     to shtml files can be passed through to embedded scripts as POST
     requests, rather being downgraded to GET requests. [Graham Leggett]

  *) mod_ssl: Fix TLS upgrade (RFC 2817) support.  PR 41231.  [Joe Orton]

  *) scoreboard: Correctly declare ap_time_process_request.
     PR 43789 [Tom Donovan <Tom.Donovan acm.org>]

  *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
     from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
     provide the unusual legacy lookup.  [William Rowe]

  *) mpm winnt: fix null pointer dereference
     PR 42572 [Davi Arnaut]

  *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
     parameters to the environment. Improve portability to
     EBCDIC machines by using apr_toupper(). [Martin Kraemer]

  *) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability
     to authorize an authenticated user via a "require ldap-group X" directive
     where the user is not in group X, but is in a subgroup contained in X.
     PR 42891 [Paul J. Reder]

  *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]

  *) apxs: Enhance -q flag to print all known variables and their values
     when invoked without variable name(s).
     [William Rowe, Sander Temme]

  *) apxs: Eliminate run-time check for mod_so.  PR 40653.
     [David M. Lee <dmlee crossroads.com>]

  *) beos MPM: Create pmain pool and run modules' child_init hooks when
     entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
     [Chris Darroch]

  *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
     cleanups registered in modules' child_init hooks are performed.
     [Chris Darroch]

  *) Fix issue which could cause error messages to be written to access logs
     on Win32.  PR 40476.  [Tom Donovan <Tom.Donovan acm.org>]

  *) The LockFile directive, which specifies the location of
     the accept() mutex lockfile, is deprecated. Instead, the
     AcceptMutex directive now takes an optional lockfile
     location parameter, ala SSLMutex. [Jim Jagielski]

  *) mod_authn_dbd: Export any additional columns queried in the SQL select
     into the environment with the name AUTHENTICATE_<COLUMN>. This brings
     mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]

  *) mod_dbd: Key the storage of prepared statements on the hex string
     value of server_rec, rather than the server name, as the server name
     may change (eg when the server name is set) at any time, causing
     weird behaviour in modules dependent on mod_dbd. [Graham Leggett]

  *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]

  *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
     the first bucket from the brigade, finds it not to be a FILE
     bucket and barfs. The fix is to pass a bucket rather than a brigade.
     [Niklas Edmundsson <nikke acc.umu.se>]

  *) mod_rewrite: support rewritemap by SQL query [Nick Kew]

  *) ap_get_server_version() has been removed.  Third-party modules must
     now use ap_get_server_banner() or ap_get_server_description().
     [Jeff Trawick]

  *) All MPMs: Introduce a check_config phase between pre_config and
     open_logs, to allow modules to review interdependent configuration
     directive values and adjust them while messages can still be logged
     to the console.  Handle relevant MPM directives during this phase
     and format messages for both the console and the error log, as
     appropriate.  [Chris Darroch]

  *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
     to circumvent the symbolic link checks imposed by FollowSymLinks and
     SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]

  *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
     configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
     The default is none as this is far greater debugging resolution than
     the typical administrator is prepared to untangle.  [William Rowe]

  *) mod_disk_cache: If possible, check if the size of an object to cache is
     within the configured boundaries before actually saving data.
     [Niklas Edmundsson <nikke acc.umu.se>]

  *) Worker and event MPMs: Remove improper scoreboard updates which were
     performed in the event of a fork() failure.  [Chris Darroch]

  *) Add support for fcgi:// proxies to mod_rewrite.
     [Markus Schiegl <ms schiegl.com>]

  *) Remove incorrect comments from scoreboard.h regarding conditional
     loading of worker_score structure with mod_status, and remove unused
     definitions relating to old life_status field.
     [Chris Darroch <chrisd pearsoncmg.com>]

  *) Remove allocation of memory for unused array of lb_score pointers
     in ap_init_scoreboard().  [Chris Darroch <chrisd pearsoncmg.com>]

  *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
     [Garrett Rooney, Jim Jagielski, Paul Querna]

  *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
     [Chris Darroch <chrisd pearsoncmg.com>]

  *) mod_charset_lite: Remove Content-Length when output filter can
     invalidate it.  Warn when input filter can invalidate it.
     [Jeff Trawick]

  *) Authz: Add the new module mod_authn_core that will provide common
     authn directives such as 'AuthType', 'AuthName'.  Move the directives
     'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
     into mod_authn_core. [Brad Nicholes]

  *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
     into the new module mod_access_compat which can be loaded to provide
     support for these directives.
     [Brad Nicholes]

  *) Authz: Move the 'Require' directive from the core module as well as
     add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
     and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
     logic into the authorization processing. [Brad Nicholes]

  *) Authz: Add the new module mod_authz_core which acts as the
     authorization provider vector and contains common authz
     directives. [Brad Nicholes]

  *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
     'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]

  *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
     host-based access control provided by mod_authz_host and invoked
     through the 'Require' directive. [Brad Nicholes]

  *) Authz: Convert all of the authz modules from hook based to
     provider based. [Brad Nicholes]

  *) mod_cache: Add CacheMinExpire directive to set the minimum time in
     seconds to cache a document.
     [Brian Akins <brian.akins turner.com>, Ruediger Pluem]

  *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]

  *) Fix typo in ProxyStatus syntax error message.
     [Christophe Jaillet <christophe.jaillet wanadoo.fr>]

  *) Asynchronous write completion for the Event MPM.  [Brian Pane]

  *) Added an End-Of-Request bucket type.  The logging of a request and
     the freeing of its pool are now done when the EOR bucket is destroyed.
     This has the effect of delaying the logging until right after the last
     of the response is sent; ap_core_output_filter() calls the access logger
     indirectly when it destroys the EOR bucket.  [Brian Pane]

  *) Rewrite of logresolve support utility: IPv6 addresses are now supported
     and the format of statistical output has changed. [Colm MacCarthaigh]

  *) Rewrite of ap_coreoutput_filter to do nonblocking writes  [Brian Pane]

  *) Added new connection states for handler and write completion
     [Brian Pane]

  *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs.  PR 34264.
     [Justin Erenkrantz]

  *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
     allowing string-valued client certificate attributes to be used for
     access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
     [Martin Kraemer, David Reid]
