587 to newly created sub requests; as these are later on used
588 as true requests with an internal redirect. This allows for
589 mod_cache et.al. to trap the results of the redirect.
590 [Dirk-Willem van Gulik, Ruediger Pluem]
592 *) mod_ldap: Add support (taking advantage of the new APR capability)
593 for ldap rebind callback while chasing referrals. This allows direct
594 searches on LDAP servers (in particular MS Active Directory 2003+)
595 using referrals without the use of the global catalog.
596 PRs 26538, 40268, and 42557 [Paul J. Reder]
598 *) mod_ssl: Added server name indication support (SNI, RFC 4366).
599 PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
600 can be created with test/make_sni.sh [Dirk-Willem van Gulik].
602 *) ApacheMonitor.exe: Introduce --kill argument for use by the
603 installer. This will permit the installation tool to remove
604 all running instances before attempting to remove the .exe.
607 *) mod_ssl: Add support for OCSP validation of client certificates.
608 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
610 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
612 *) core: Add the option to keep aside a request body up to a certain
613 size that would otherwise be discarded, to be consumed by filters
614 such as mod_include. When enabled for a directory, POST requests
615 to shtml files can be passed through to embedded scripts as POST
616 requests, rather being downgraded to GET requests. [Graham Leggett]
618 *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
620 *) scoreboard: Correctly declare ap_time_process_request.
621 PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
623 *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
624 from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
625 provide the unusual legacy lookup. [William Rowe]
627 *) mpm winnt: fix null pointer dereference
628 PR 42572 [Davi Arnaut]
630 *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
631 parameters to the environment. Improve portability to
632 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
634 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
635 to authorize an authenticated user via a "require ldap-group X" directive
636 where the user is not in group X, but is in a subgroup contained in X.
637 PR 42891 [Paul J. Reder]
639 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
641 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
642 for SDKs that define LDAP_NO_LIMIT to something other than -1.

645 *) apxs: Enhance -q flag to print all known variables and their values
646 when invoked without variable name(s).

649 *) apxs: Eliminate run-time check for mod_so. PR 40653.
650 [David M. Lee <dmlee crossroads.com>]
652 *) beos MPM: Create pmain pool and run modules' child_init hooks when
653 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
656 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
657 cleanups registered in modules' child_init hooks are performed.
660 *) mod_dbd: Stash DBD connections in request_config of initial request
661 only, or else sub-requests and internal redirections may cause
662 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
664 *) Fix issue which could cause error messages to be written to access logs
665 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
667 *) The LockFile directive, which specifies the location of
668 the accept() mutex lockfile, is deprecated. Instead, the
669 AcceptMutex directive now takes an optional lockfile
670 location parameter, ala SSLMutex. [Jim Jagielski]
672 *) mod_authn_dbd: Export any additional columns queried in the SQL select
673 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
674 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
676 *) mod_dbd: Key the storage of prepared statements on the hex string
677 value of server_rec, rather than the server name, as the server name
678 may change (eg when the server name is set) at any time, causing
679 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
681 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
683 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
684 the first bucket from the brigade, finds it not to be a FILE
685 bucket and barfs. The fix is to pass a bucket rather than a brigade.
686 [Niklas Edmundsson <nikke acc.umu.se>]
688 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
690 *) ap_get_server_version() has been removed. Third-party modules must
691 now use ap_get_server_banner() or ap_get_server_description().
694 *) All MPMs: Introduce a check_config phase between pre_config and
695 open_logs, to allow modules to review interdependent configuration
696 directive values and adjust them while messages can still be logged
697 to the console. Handle relevant MPM directives during this phase
698 and format messages for both the console and the error log, as
699 appropriate. [Chris Darroch]
701 *) mod_proxy: don't URLencode tilde in path component
702 [Stijn Hoop <stijn sandcat.nl>]
704 *) mpm_winnt: Fix return values from wait_for_many_objects.
705 The return value is index to the signaled thread in the
706 creted_threads array. We can not use WAIT_TIMEOUT because
707 his value is defined as 258, thus limiting the MaxThreads
708 to that value. [Mladen Turk]
710 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
711 to circumvent the symbolic link checks imposed by FollowSymLinks and
712 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
714 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
715 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
716 The default is none as this is far greater debugging resolution than
717 the typical administrator is prepared to untangle. [William Rowe]
719 *) mod_disk_cache: If possible, check if the size of an object to cache is
720 within the configured boundaries before actually saving data.
721 [Niklas Edmundsson <nikke acc.umu.se>]
723 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
724 final name. [Davi Arnaut <davi haxent.com.br>]
726 *) Worker and event MPMs: Remove improper scoreboard updates which were
727 performed in the event of a fork() failure. [Chris Darroch]
729 *) Add support for fcgi:// proxies to mod_rewrite.
730 [Markus Schiegl <ms schiegl.com>]
732 *) Remove incorrect comments from scoreboard.h regarding conditional
733 loading of worker_score structure with mod_status, and remove unused
734 definitions relating to old life_status field.
735 [Chris Darroch <chrisd pearsoncmg.com>]
737 *) Remove allocation of memory for unused array of lb_score pointers
738 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
740 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.

743 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
744 [Chris Darroch <chrisd pearsoncmg.com>]
746 *) mod_charset_lite: Remove Content-Length when output filter can
747 invalidate it. Warn when input filter can invalidate it.
750 *) Authz: Add the new module mod_authn_core that will provide common
751 authn directives such as 'AuthType', 'AuthName'. Move the directives
752 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
753 into mod_authn_core. [Brad Nicholes]
755 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
756 into the new module mod_access_compat which can be loaded to provide
757 support for these directives.
760 *) Authz: Move the 'Require' directive from the core module as well as
761 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
762 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
763 logic into the authorization processing. [Brad Nicholes]
765 *) Authz: Add the new module mod_authz_core which acts as the
766 authorization provider vector and contains common authz
767 directives. [Brad Nicholes]
769 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
770 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
772 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
773 host-based access control provided by mod_authz_host and invoked
774 through the 'Require' directive. [Brad Nicholes]
776 *) Authz: Convert all of the authz modules from hook based to
777 provider based. [Brad Nicholes]
779 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
780 seconds to cache a document.
781 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
783 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
785 *) Fix typo in ProxyStatus syntax error message.
786 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
788 *) Asynchronous write completion for the Event MPM. [Brian Pane]
790 *) Added an End-Of-Request bucket type. The logging of a request and
791 the freeing of its pool are now done when the EOR bucket is destroyed.
792 This has the effect of delaying the logging until right after the last
793 of the response is sent; ap_core_output_filter() calls the access logger
794 indirectly when it destroys the EOR bucket. [Brian Pane]
796 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
797 and the format of statistical output has changed. [Colm MacCarthaigh]
799 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
801 *) Added new connection states for handler and write completion
804 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
807 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
808 allowing string-valued client certificate attributes to be used for
809 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
