414 subrequests to support message bodies. Make sure that safety
415 checks within the core and within the proxy are not triggered

417 proxied POST requests within mod_include. [Graham Leggett]
419 *) mod_auth_form: Make sure the input filter stack is properly set

477 of encrypting and decrypting sessions wherever they may be stored.
478 Introduces a level of privacy when sessions are stored on the
479 browser. [Graham Leggett]
481 *) mod_session_cookie: Add a session implementation capable of storing
482 session information within cookies on the browser. Useful for high
483 volume sites where server bound sessions are too resource intensive.
486 *) mod_session: Add a generic session interface to unify the different
487 attempts at saving persistent sessions across requests.
490 *) core, authn/z: Avoid calling access control hooks for internal requests
491 with configurations which match those of initial request. Revert to
492 original behaviour (call access control hooks for internal requests
493 with URIs different from initial request) if any access control hooks or

600 *) mod_dbd: Stash DBD connections in request_config of initial request
601 only, or else sub-requests and internal redirections may cause
602 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
604 *) Fix issue which could cause error messages to be written to access logs
605 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
607 *) The LockFile directive, which specifies the location of
608 the accept() mutex lockfile, is deprecated. Instead, the
609 AcceptMutex directive now takes an optional lockfile
610 location parameter, ala SSLMutex. [Jim Jagielski]
612 *) mod_authn_dbd: Export any additional columns queried in the SQL select
613 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
614 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
616 *) mod_dbd: Key the storage of prepared statements on the hex string
617 value of server_rec, rather than the server name, as the server name
618 may change (eg when the server name is set) at any time, causing
619 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
621 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
623 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
624 the first bucket from the brigade, finds it not to be a FILE
625 bucket and barfs. The fix is to pass a bucket rather than a brigade.

628 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
630 *) ap_get_server_version() has been removed. Third-party modules must
631 now use ap_get_server_banner() or ap_get_server_description().
634 *) All MPMs: Introduce a check_config phase between pre_config and
635 open_logs, to allow modules to review interdependent configuration
636 directive values and adjust them while messages can still be logged
637 to the console. Handle relevant MPM directives during this phase
638 and format messages for both the console and the error log, as
639 appropriate. [Chris Darroch]
641 *) mod_proxy: don't URLencode tilde in path component
642 [Stijn Hoop <stijn sandcat.nl>]
644 *) mpm_winnt: Fix return values from wait_for_many_objects.
645 The return value is index to the signaled thread in the
646 creted_threads array. We can not use WAIT_TIMEOUT because
647 his value is defined as 258, thus limiting the MaxThreads
648 to that value. [Mladen Turk]
650 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
651 to circumvent the symbolic link checks imposed by FollowSymLinks and
652 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
654 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
655 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
656 The default is none as this is far greater debugging resolution than
657 the typical administrator is prepared to untangle. [William Rowe]

686 *) mod_charset_lite: Remove Content-Length when output filter can
687 invalidate it. Warn when input filter can invalidate it.
690 *) Authz: Add the new module mod_authn_core that will provide common
691 authn directives such as 'AuthType', 'AuthName'. Move the directives
692 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
693 into mod_authn_core. [Brad Nicholes]
695 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
696 into the new module mod_access_compat which can be loaded to provide
697 support for these directives.
700 *) Authz: Move the 'Require' directive from the core module as well as
701 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
702 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
703 logic into the authorization processing. [Brad Nicholes]
705 *) Authz: Add the new module mod_authz_core which acts as the
706 authorization provider vector and contains common authz
707 directives. [Brad Nicholes]
709 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
710 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
712 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
713 host-based access control provided by mod_authz_host and invoked
714 through the 'Require' directive. [Brad Nicholes]
716 *) Authz: Convert all of the authz modules from hook based to
717 provider based. [Brad Nicholes]
719 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
720 seconds to cache a document.

728 *) Asynchronous write completion for the Event MPM. [Brian Pane]
730 *) Added an End-Of-Request bucket type. The logging of a request and
731 the freeing of its pool are now done when the EOR bucket is destroyed.
732 This has the effect of delaying the logging until right after the last
733 of the response is sent; ap_core_output_filter() calls the access logger
734 indirectly when it destroys the EOR bucket. [Brian Pane]
736 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
737 and the format of statistical output has changed. [Colm MacCarthaigh]
739 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
741 *) Added new connection states for handler and write completion
744 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
747 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
748 allowing string-valued client certificate attributes to be used for
749 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
