461 session information within cookies on the browser. Useful for high
462 volume sites where server bound sessions are too resource intensive.
465 *) mod_session: Add a generic session interface to unify the different
466 attempts at saving persistent sessions across requests.
469 *) core, authn/z: Avoid calling access control hooks for internal requests

579 *) mod_dbd: Stash DBD connections in request_config of initial request
580 only, or else sub-requests and internal redirections may cause
581 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
583 *) Fix issue which could cause error messages to be written to access logs
584 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
586 *) The LockFile directive, which specifies the location of
587 the accept() mutex lockfile, is deprecated. Instead, the
588 AcceptMutex directive now takes an optional lockfile
589 location parameter, ala SSLMutex. [Jim Jagielski]
591 *) mod_authn_dbd: Export any additional columns queried in the SQL select
592 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
593 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
595 *) mod_dbd: Key the storage of prepared statements on the hex string
596 value of server_rec, rather than the server name, as the server name
597 may change (eg when the server name is set) at any time, causing
598 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
600 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
602 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
603 the first bucket from the brigade, finds it not to be a FILE
604 bucket and barfs. The fix is to pass a bucket rather than a brigade.
605 [Niklas Edmundsson <nikke acc.umu.se>]
607 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
609 *) ap_get_server_version() has been removed. Third-party modules must
610 now use ap_get_server_banner() or ap_get_server_description().
613 *) All MPMs: Introduce a check_config phase between pre_config and
614 open_logs, to allow modules to review interdependent configuration
615 directive values and adjust them while messages can still be logged
616 to the console. Handle relevant MPM directives during this phase
617 and format messages for both the console and the error log, as
618 appropriate. [Chris Darroch]
620 *) mod_proxy: don't URLencode tilde in path component
621 [Stijn Hoop <stijn sandcat.nl>]
623 *) mpm_winnt: Fix return values from wait_for_many_objects.
624 The return value is index to the signaled thread in the
625 creted_threads array. We can not use WAIT_TIMEOUT because
626 his value is defined as 258, thus limiting the MaxThreads
627 to that value. [Mladen Turk]
629 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
630 to circumvent the symbolic link checks imposed by FollowSymLinks and
631 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
633 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
634 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
635 The default is none as this is far greater debugging resolution than
636 the typical administrator is prepared to untangle. [William Rowe]
638 *) mod_disk_cache: If possible, check if the size of an object to cache is
639 within the configured boundaries before actually saving data.
640 [Niklas Edmundsson <nikke acc.umu.se>]
642 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
643 final name. [Davi Arnaut <davi haxent.com.br>]
645 *) Worker and event MPMs: Remove improper scoreboard updates which were
646 performed in the event of a fork() failure. [Chris Darroch]
648 *) Add support for fcgi:// proxies to mod_rewrite.
649 [Markus Schiegl <ms schiegl.com>]
651 *) Remove incorrect comments from scoreboard.h regarding conditional
652 loading of worker_score structure with mod_status, and remove unused
653 definitions relating to old life_status field.
654 [Chris Darroch <chrisd pearsoncmg.com>]
656 *) Remove allocation of memory for unused array of lb_score pointers
657 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
659 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
660 [Garrett Rooney, Jim Jagielski, Paul Querna]
662 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
663 [Chris Darroch <chrisd pearsoncmg.com>]
665 *) mod_charset_lite: Remove Content-Length when output filter can
666 invalidate it. Warn when input filter can invalidate it.
669 *) Authz: Add the new module mod_authn_core that will provide common
670 authn directives such as 'AuthType', 'AuthName'. Move the directives
671 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
672 into mod_authn_core. [Brad Nicholes]
674 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
675 into the new module mod_access_compat which can be loaded to provide
676 support for these directives.
679 *) Authz: Move the 'Require' directive from the core module as well as
680 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
681 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
682 logic into the authorization processing. [Brad Nicholes]
684 *) Authz: Add the new module mod_authz_core which acts as the
685 authorization provider vector and contains common authz
686 directives. [Brad Nicholes]
688 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
689 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
691 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
692 host-based access control provided by mod_authz_host and invoked
693 through the 'Require' directive. [Brad Nicholes]
695 *) Authz: Convert all of the authz modules from hook based to
696 provider based. [Brad Nicholes]
698 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
699 seconds to cache a document.
700 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
702 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
704 *) Fix typo in ProxyStatus syntax error message.
705 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
707 *) Asynchronous write completion for the Event MPM. [Brian Pane]
709 *) Added an End-Of-Request bucket type. The logging of a request and
710 the freeing of its pool are now done when the EOR bucket is destroyed.
711 This has the effect of delaying the logging until right after the last
712 of the response is sent; ap_core_output_filter() calls the access logger
713 indirectly when it destroys the EOR bucket. [Brian Pane]
715 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
716 and the format of statistical output has changed. [Colm MacCarthaigh]
718 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
720 *) Added new connection states for handler and write completion
723 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
726 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
727 allowing string-valued client certificate attributes to be used for
728 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
