4 *) mod_cache: Ensure that CacheDisable can correctly appear within
5 a LocationMatch. [Graham Leggett]
7 *) mod_cache: Fix the moving of the CACHE filter, which erroneously
8 stood down if the original filter was not added by configuration.
11 *) mod_ssl: improve certificate error logging. PR 47408. [Kaspar Brand]
13 *) mod_authz_groupfile: Increase length limit of lines in the group file to
14 16MB. PR 43084. [Stefan Fritsch]
16 *) core: Increase length limit of lines in the configuration file to 16MB.
17 PR 45888. PR 50824. [Stefan Fritsch]
19 *) core: Add API for resizable buffers. [Stefan Fritsch]
21 *) mod_ldap: Enable LDAPConnectionTimeout for LDAP toolkits that have
22 LDAP_OPT_CONNECT_TIMEOUT instead of LDAP_OPT_NETWORK_TIMEOUT, such
23 as Tivoli Directory Server 6.3 and later. [Eric Covener]
25 *) mod_ldap: Change default number of retries from 10 to 3, and add
26 an LDAPRetries and LDAPRetryDelay directives. [Eric Covener]
28 *) mod_authnz_ldap: Don't retry during authentication, because this just
29 multiplies the ample retries already being done by mod_ldap. [Eric Covener]
31 *) configure: Allow to explicitly disable modules even with module selection
32 'reallyall'. [Stefan Fritsch]
34 *) mod_rewrite: Check validity of each internal (int:) RewriteMap even if the
35 RewriteEngine is disabled in server context, avoiding a crash while
36 referencing the invalid int: map at runtime. PR 50994.
37 [Ben Noordhuis <info noordhuis nl>]
39 *) mod_ssl, configure: require OpenSSL 0.9.7 or later. [Kaspar Brand]
41 *) mod_ssl: remove ssl_toolkit_compat layer. [Kaspar Brand]
43 *) mod_ssl, configure, ab: drop support for RSA BSAFE SSL-C toolkit.
46 *) mod_usertrack: Run mod_usertrack earlier in the fixups hook to ensure the
47 cookie is set when modules such as mod_rewrite trigger a redirect. Also
48 use r->err_headers_out for the cookie, for the same reason. PR29755.
49 [Sami J. Mäkinen <sjm almamedia fi>, Eric Covener]
51 *) mod_proxy_http, mod_proxy_connect: Add 'proxy-status' and
52 'proxy-source-port' request notes for logging. PR 30195. [Stefan Fritsch]
54 *) configure: Enable ldap modules in 'all' and 'most' selections if ldap
55 is compiled into apr-util. [Stefan Fritsch]
57 *) core: Add ap_check_cmd_context()-check if a command is executed in
58 .htaccess file. [Stefan Fritsch]
60 *) mod_deflate: Fix endless loop if first bucket is metadata. PR 51590.

63 Changes with Apache 2.3.14
65 *) mod_proxy_ajp: Improve trace logging. [Rainer Jung]
67 *) mod_proxy_ajp: Respect "reuse" flag in END_REPONSE packets.
70 *) mod_proxy: enable absolute URLs to be rewritten with ProxyPassReverse,
71 e.g. to reverse proxy "Location: https://other-internal-server/login"
74 *) prefork, worker, event: Make sure crashes are logged to the error log if
75 httpd has already detached from the console. [Stefan Fritsch]
77 *) prefork, worker, event: Reduce period during startup/restart where a
78 successive signal may be lost. PR 43696. [Arun Bhalla <arun shme net>]
80 *) mod_allowmethods: Correct Merging of "reset" and do not allow an
81 empty parameter list for the AllowMethods directive. [Rainer Jung]
83 *) configure: Update selection of modules for 'all' and 'most'. 'all' will
84 now enable all modules except for example and test modules. Make the
85 selection for 'most' more useful (including ssl and proxy). Both 'all'
86 and 'most' will now disable modules if dependencies are missing instead
87 of aborting. If a specific module is requested with --enable-XXX=yes,
88 missing dependencies will still cause configure to exit with an error.
91 *) mod_ldap: Revert the integration of apr-ldap as ap_ldap which was done
92 in 2.3.13. [Stefan Fritsch]
94 *) core: For '*' or '_default_' vhosts, use a wildcard address of any
95 address family, rather than IPv4 only. [Joe Orton]
97 *) core, mod_rewrite, mod_ssl, mod_nw_ssl: Make the SERVER_NAME variable
98 include [ ] for literal IPv6 addresses, as mandated by RFC 3875.

105 ap_scan_script_header_err*_ex functions that take a module index for
107 mod_cgi, mod_cgid, mod_proxy_fcgi, mod_proxy_scgi, mod_isapi: Use the
108 new functions in order to make logging configurable per-module.
111 *) mod_dir: Add DirectoryIndexRedirect to send an external redirect to
112 the proper index. [Eric Covener]
114 *) mod_deflate: Don't try to compress requests with a zero sized body.
115 PR 51350. [Stefan Fritsch]
117 *) core: Fix startup on IP6-only systems. PR 50592. [Joe Orton,
118 <root linkage white-void net>]

122 whitelist in suexec. PR 51499. [Graham Laverty <graham reg ca>,
125 *) mod_rewrite: Fix regexp RewriteCond with NoCase. [Stefan Fritsch]
127 *) mod_log_debug: New module that allows to log custom messages at various
128 phases in the request processing. [Stefan Fritsch]
130 *) mod_ssl: Add some debug logging when loading server certificates.
131 PR 37912. [Nick Burch <nick burch alfresco com>]
133 *) configure: Support reallyall option also for --enable-mods-static.
136 *) mod_socache_dc: add --with-distcache to configure for choosing
137 the distcache installation directory. [Rainer Jung]
139 *) mod_socache_dc: use correct build variable MOD_SOCACHE_DC_LDADD
140 instead of MOD_SOCACHE_LDADD in build macro. [Rainer Jung]
142 *) mod_lua, mod_deflate: respect platform specific runpath linker
145 *) configure: Only link the httpd binary against PCRE. No other support
146 binary needs PCRE. [Rainer Jung]
148 *) configure: tolerate dependency checking failures for modules if
149 they have been enabled implicitely. [Rainer Jung]
151 *) configure: Allow to specify module specific custom linker flags via
152 the MOD_XXX_LDADD variables. [Rainer Jung]
154 Changes with Apache 2.3.13
156 *) ab: Support specifying the local address to use. PR 48930.
157 [Peter Schuller <scode spotify com>]
159 *) core: Add support to ErrorLogFormat for logging the system unique
160 thread id under Linux. [Stefan Fritsch]
162 *) event: New AsyncRequestWorkerFactor directive to influence how many
163 connections will be accepted per process. [Stefan Fritsch]
165 *) prefork, worker, event: Rename MaxClients to MaxRequestWorkers which
166 describes more accurately what it does. [Stefan Fritsch]
168 *) rotatelogs: Add -p argument to specify custom program to invoke
169 after a log rotation. PR 51285. [Sven Ulland <sveniu ifi.uio.no>,
172 *) mod_ssl: Don't do OCSP checks for valid self-issued certs. [Kaspar Brand]
174 *) mod_ssl: Avoid unnecessary renegotiations with SSLVerifyDepth 0.
175 PR 48215. [Kaspar Brand]
177 *) mod_status: Display information about asynchronous connections in the
178 server-status. PR 44377. [Stefan Fritsch]
180 *) mpm_event: If the number of connections of a process is very high, or if
181 all workers are busy, don't accept new connections in that process.
184 *) mpm_event: Process lingering close asynchronously instead of tying up
185 worker threads. [Jeff Trawick, Stefan Fritsch]
187 *) mpm_event: If MaxMemFree is set, limit the number of pools that is kept
188 around. [Stefan Fritsch]
190 *) mpm_event: Fix graceful restart aborting connections. PR 43359.
191 [Takashi Sato <takashi lans-tv com>]
193 *) mod_ssl: Disable AECDH ciphers in example config. PR 51363.
194 [Rob Stradling <rob comodo com>]
196 *) core: Introduce new function ap_get_conn_socket() to access the socket of
197 a connection. [Stefan Fritsch]
199 *) mod_data: Introduce a filter to support RFC2397 data URLs. [Graham
202 *) mod_userdir/mod_alias/mod_vhost_alias: Correctly set DOCUMENT_ROOT,
203 CONTEXT_DOCUMENT_ROOT, CONTEXT_PREFIX. PR 26052. PR 46198.
206 *) core: Allow to override document_root on a per-request basis. Introduce
207 new context_document_root and context_prefix which provide information
208 about non-global URI-to-directory mappings (from e.g. mod_userdir or
209 mod_alias) to scripts. PR 49705. [Stefan Fritsch]
211 *) core: Add <ElseIf> and <Else> to complement <If> sections.
214 *) mod_ext_filter: Remove DebugLevel option in favor of per-module loglevel.
217 *) mod_include: Make the "#if expr" element use the new "ap_expr" expression
218 parser. The old parser can still be used by setting the new directive
219 SSILegacyExprParser. [Stefan Fritsch]
221 *) core: Add some features to ap_expr for use by mod_include: a restricted
222 mode that does not allow to bypass request access restrictions; new
223 variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an
224 alias for -U; an additional data entry in ap_expr_eval_ctx_t for use by
225 the consumer; an extensible ap_expr_exec_ctx() API that allows to use that
226 data entry. [Stefan Fritsch]
228 *) mod_include: Merge directory configs instead of one SSI* config directive
229 causing all other per-directory SSI* config directives to be reset.
232 *) mod_charset_lite: Remove DebugLevel option in favour of per-module
233 loglevel. [Stefan Fritsch]
235 *) core: Add ap_regexec_len() function that works with non-null-terminated
236 strings. PR 51231. [Yehezkel Horowitz <horowity checkpoint com>]
238 *) mod_authnz_ldap: If the LDAP server returns constraint violation,
239 don't treat this as an error but as "auth denied". [Stefan Fritsch]
241 *) mod_proxy_fcgi|scgi: Add support for "best guess" of PATH_INFO
242 for SCGI/FCGI. PR 50880, 50851. [Mark Montague <mark catseye.org>,
245 *) mod_cache: When content is served stale, and there is no means to
246 revalidate the content using ETag or Last-Modified, and we have
247 mandated no stale-on-error behaviour, stand down and don't cache.
248 Saves a cache write that will never be read.
251 *) mod_reqtimeout: Fix a timed out connection going into the keep-alive
252 state after a timeout when discarding a request body. PR 51103.
255 *) core: Add various file existance test operators to ap_expr.

271 *) mod_authnz_ldap: Resolve crash when LDAP is used for authorization only
272 [Scott Hill <shill genscape.com>]
274 *) support: Make sure check_forensic works with mod_unique_id loaded
277 *) Add child_status hook for tracking creation/termination of MPM child
278 processes. Add end_generation hook for notification when the last
279 MPM child of a generation exits. [Jeff Trawick]
281 *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
282 process as opposed to disabling caching completely. This allows to use
283 the non-shared-memory cache as a workaround for the shared memory cache
284 not being available during graceful restarts. PR 48958. [Stefan Fritsch]
286 *) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,
287 necessary if a module (like mod_perl) registers additional modules late
288 in the startup phase. [Stefan Fritsch]
290 *) core: Prevent segfault if DYNAMIC_MODULE_LIMIT is reached. PR 51072.
291 [Torsten Förtsch <torsten foertsch gmx net>]
293 *) WinNT MPM: Improve robustness under heavy load. [Jeff Trawick]
295 *) MinGW build improvements. PR 49535. [John Vandenberg

298 *) core: Support module names with colons in loglevel configuration.
299 [Torsten Förtsch <torsten foertsch gmx net>]
301 *) mod_ssl, ab: Support OpenSSL compiled without SSLv2 support.
304 *) core: Abort if the MPM is changed across restart. [Jeff Trawick]
306 *) mod_proxy_ajp: Add support for 'ProxyErrorOverride on'. PR 50945.
307 [Peter Pramberger <peter pramberger.at>, Jim Jagielski]
309 *) mod_proxy_fcgi: Add support for 'ProxyErrorOverride on'. PR 50913.
310 [Mark Montague <mark catseye.org>, Jim Jagielski]
312 *) core: Change the APIs of ap_cfg_getline() and ap_cfg_getc() to return an
313 error code. Abort with a nice error message if a config line is too long.
314 Partial fix for PR 50824. [Stefan Fritsch]
316 *) mod_info: Dump config to stdout during startup if -DDUMP_CONFIG is
317 specified. PR 31956. [Stefan Fritsch]
319 *) Restore visibility of DEFAULT_PIDLOG to core and modules. MPM
320 helper function ap_remove_pid() added. [Jeff Trawick]

338 *) mod_ldap: Add LDAPConnectionPoolTTL to give control over lifetime
339 of bound backend LDAP connections. PR47634 [Eric Covener]
341 *) mod_cache: Make CacheEnable and CacheDisable configurable per
342 directory in addition to per server, making them work from within
343 a LocationMatch. [Graham Leggett]
345 *) worker, event, prefork: Correct several issues when built as
346 DSOs; most notably, the scoreboard was reinitialized during graceful
347 restart, such that processes of the previous generation were not
348 observable. [Jeff Trawick]
350 Changes with Apache 2.3.11
352 *) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI.
353 Win32's cscript interpreter can only use a single quote as comment char.
356 *) mod_proxy: balancer-manager now uses POST instead of GET.
359 *) core: new util function: ap_parse_form_data(). Previously,
360 this capability was tucked away in mod_request. [Jim Jagielski]
362 *) core: new hook: ap_run_pre_read_request. [Jim Jagielski]
364 *) mod_cache: When a request other than GET or HEAD arrives, we must
365 invalidate existing cache entities as per RFC2616 13.10. PR 15868.
368 *) modules: Fix many modules that were not correctly initializing if they
369 were not active during server startup but got enabled later during a
370 graceful restart. [Stefan Fritsch]
372 *) core: Create new ap_state_query function that allows modules to determine
373 if the current configuration run is the initial one at server startup,
374 and if the server is started for testing/config dumping only.
377 *) mod_proxy: Runtime configuration of many parameters for existing
378 balancers via the balancer-manager. [Jim Jagielski]
380 *) mod_proxy: Runtime addition of new workers (BalancerMember) for existing
381 balancers via the balancer-manager. [Jim Jagielski]
383 *) mod_cache: When a bad Expires date is present, we need to behave as if
384 the Expires is in the past, not as if the Expires is missing. PR 16521.
385 [Co-Advisor <coad@measurement-factory.com>]
387 *) mod_cache: We must ignore quoted-string values that appear in a
388 Cache-Control header. PR 50199. [Graham Leggett]
390 *) mod_dav: Revert change to send 501 error if unknown Content-* header is
391 received for a PUT request. PR 42978. [Stefan Fritsch]
393 *) mod_cache: Respect s-maxage as described by RFC2616 14.9.3, which must
394 take precedence if present. PR 35247. [Graham Leggett]
396 *) mod_ssl: Fix a possible startup failure if multiple SSL vhosts
397 are configured with the same ServerName and private key file.
398 [Masahiro Matsuya <mmatsuya redhat.com>, Joe Orton]
400 *) mod_socache_dc: Make module compile by fixing some typos.
401 PR 50735 [Mark Montague <mark catseye.org>]
403 *) prefork: Update MPM state in children during a graceful stop or
404 restart. PR 41743. [Andrew Punch <andrew.punch 247realmedia.com>]
406 *) mod_mime: Ignore leading dots when looking for mime extensions.
407 PR 50434 [Stefan Fritsch]
409 *) core: Add support to set variables with the 'Define' directive. The
410 variables that can then be used in the config using the ${VAR} syntax
411 known from envvar interpolation. [Stefan Fritsch]
413 *) mod_proxy_http: make adding of X-Forwarded-* headers configurable.
414 ProxyAddHeaders defaults to On. [Vincent Deffontaines]
416 *) mod_slotmem_shm: Increase memory alignment for slotmem data.
419 *) mod_ssl: Add config options for OCSP: SSLOCSPResponderTimeout,
420 SSLOCSPResponseMaxAge, SSLOCSPResponseTimeSkew.
421 [Kaspar Brand <httpd-dev.2011 velox.ch>]
423 *) mod_ssl: Revamp output buffering to reduce network overhead for
424 output fragmented into many buckets, such as chunked HTTP responses.
427 *) core: Apply <If> sections to all requests, not only to file base requests.
428 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
429 The merging of <If> sections now happens after the merging of <Location>
430 sections, even if an <If> section is embedded inside a <Directory> or
431 <Files> section. [Stefan Fritsch]
433 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
434 and using slotmem. Create foundation for dynamic growth/changes of
435 members within a balancer. Remove BalancerNonce in favor of a
436 per-balancer 'nonce' parameter. [Jim Jagielski]
438 *) mod_status: Don't show slots which are disabled by MaxClients as open.
439 PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]

444 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
445 authorization directives were mixed. [Stefan Fritsch]
447 *) mod_authn_socache: change directive name from AuthnCacheProvider
448 to AuthnCacheProvideFor. The term "provider" is overloaded in
449 this module, and we should avoid confusion between the provider
450 of a backend (AuthnCacheSOCache) and the authn provider(s) for
451 which this module provides cacheing (AuthnCacheProvideFor).
454 *) mod_proxy_http: Allocate the fake backend request from a child pool
455 of the backend connection, instead of misusing the pool of the frontend
456 request. Fixes a thread safety issue where buckets set aside in the
457 backend connection leak into other threads, and then disappear when
458 the frontend request is cleaned up, in turn causing corrupted buckets
459 to make other threads spin. [Graham Leggett]
461 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
462 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
463 escape other special characters with backslashes. The old format can
464 still be used with the LegacyDNStringFormat argument to SSLOptions.
466 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
467 scripts and mod_rewrite. [Stefan Fritsch]
469 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in
470 RewriteCond. [Stefan Fritsch]
472 *) mod_rewrite: Allow to unset environment variables using E=!VAR.
473 PR 49512. [Mark Drayton <mark markdrayton info>, Stefan Fritsch]
475 *) mod_headers: Restore the 2.3.8 and earlier default for the first
476 argument of the Header directive ("onsuccess"). [Eric Covener]
478 *) core: Disallow the mixing of relative and absolute Options PR 33708.
479 [Sönke Tesch <st kino-fahrplan.de>]
481 *) core: When exporting request headers to HTTP_* environment variables,
482 drop variables whose names contain invalid characters. Describe in the
483 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
485 *) core: When selecting an IP-based virtual host, favor an exact match for
486 the port over a wildcard (or omitted) port instead of favoring the one
487 that came first in the configuration file. [Eric Covener]
489 *) core: Overlapping virtual host address/port combinations now implicitly
490 enable name-based virtual hosting for that address. The NameVirtualHost
491 directive has no effect, and _default_ is interpreted the same as "*".
494 *) core: In the absence of any Options directives, the default is now
495 "FollowSymlinks" instead of "All". [Igor Galić]
497 *) rotatelogs: Add -e option to write logs through to stdout for optional
498 further processing. [Graham Leggett]
500 *) mod_ssl: Correctly read full lines in input filter when the line is
501 incomplete during first read. PR 50481. [Ruediger Pluem]
503 *) mod_authz_core: Add AuthzSendForbiddenOnFailure directive to allow
504 sending '403 FORBIDDEN' instead of '401 UNAUTHORIZED' if authorization
505 fails for an authenticated user. PR 40721. [Stefan Fritsch]
507 Changes with Apache 2.3.10
509 *) mod_rewrite: Don't implicitly URL-escape the original query string
510 when no substitution has changed it. PR 50447. [Eric Covener]
512 *) core: Honor 'AcceptPathInfo OFF' during internal redirects,
513 such as per-directory mod_rewrite substitutions. PR 50349.
516 *) mod_rewrite: Add 'RewriteOptions InheritBefore' to put the base
517 rules/conditions before the overridden rules/conditions. PR 39313.
518 [Jérôme Grandjanny <jerome.grandjanny cea.fr>]
520 *) mod_autoindex: add IndexIgnoreReset to reset the list of IndexIgnored

524 *) mod_cgid: RLimit* directive support for mod_cgid. PR 42135
527 *) core: Fail startup when the argument to ServerName looks like a glob
528 or a regular expression instead of a hostname (*?[]). PR 39863
529 [Rahul Nair <rahul.g.nair gmail.com>]

532 to UserDir directive, leaving enable/disable of userlists unmerged.
533 PR 44076 [Eric Covener]
535 *) httpd: When no -k option is provided on the httpd command line, the server
536 was starting without checking for an existing pidfile. PR 50350
539 *) mod_proxy: Put the worker in error state if the SSL handshake with the
540 backend fails. PR 50332.
541 [Daniel Ruggeri <DRuggeri primary.net>, Ruediger Pluem]
543 *) mod_cache_disk: Fix Windows build which was broken after renaming
544 the module. [Gregg L. Smith]
546 Changes with Apache 2.3.9
548 *) SECURITY: CVE-2010-1623 (cve.mitre.org)
549 Fix a denial of service attack against mod_reqtimeout.
552 *) mod_headers: Change default first argument of Header directive
553 from "onsuccess" to "always". [Eric Covener]
555 *) mod_include: Add the onerror attribute to the include element,
556 allowing an URL to be specified to include on error. [Graham
559 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be
560 consistent with the naming of other modules. [Graham Leggett]
562 *) mod_setenvif: Add SetEnvIfExpr directive to set env var depending on
563 expression. [Stefan Fritsch]
565 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
568 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
569 binary (Suexec Off), or force startup failure if suEXEC is required
570 but not supported (Suexec On). Change SuexecUserGroup to fail
571 startup instead of just printing a warning if suEXEC is disabled.
574 *) core: Add Error directive for aborting startup or htaccess processing
575 with a specified error message. [Jeff Trawick]
577 *) mod_rewrite: Fix the RewriteEngine directive to work within a
578 location. Previously, once RewriteEngine was switched on globally,
579 it was impossible to switch off. [Graham Leggett]
581 *) core, mod_include, mod_ssl: Move the expression parser derived from
582 mod_include back into mod_include. Replace ap_expr with a parser
583 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
584 ap_expr's public interface and provide hooks for modules to add variables

719 overridden together as desired using PassEnv etc; see mod_env.
722 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
723 capture a stale backend response, perform If-Modified-Since requests
724 against the backend, and serving from the cache all 304 responses.
725 This restores pre-2.2.4 cache behavior. [William Rowe]
727 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
728 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop

746 variable being echoed or set to be decoded and then encoded as separate
747 steps. PR47686 [Graham Leggett]
749 *) mod_cache: Add a discrete commit_entity() provider function within the
750 mod_cache provider interface which is called to indicate to the
751 provider that caching is complete, giving the provider the opportunity
752 to commit temporary files permanently to the cache in an atomic
753 fashion. Replace the inconsistent use of error cleanups with a formal
754 set of pool cleanups attached to a subpool, which is destroyed on error.
757 *) mod_cache: Change the signature of the store_body() provider function
758 within the mod_cache provider interface to support an "in" brigade
759 and an "out" brigade instead of just a single input brigade. This
760 gives a cache provider the option to consume only part of the brigade
761 passed to it, rather than the whole brigade as was required before.
762 This fixes an out of memory and a request timeout condition that would
763 occur when the original document was a large file. Introduce
764 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
765 the amount of data to attempt to cache at a time. [Graham Leggett]
767 *) core: Add ErrorLogFormat to allow configuring error log format, including
768 additional information that is logged once per connection or request. Add
769 error log IDs for connections and request to allow correlating error log
770 lines and the corresponding access log entry. [Stefan Fritsch]
772 *) core: Disable sendfile by default. [Stefan Fritsch]
774 *) mod_cache: Check the request to determine whether we are allowed
775 to return cached content at all, and respect a "Cache-Control:
776 no-cache" header from a client. Previously, "no-cache" would
777 behave like "max-age=0". [Graham Leggett]
779 *) mod_cache: Use a proper filter context to hold filter data instead
780 of misusing the per-request configuration. Fixes a segfault on trunk
781 when the normal handler is used. [Graham Leggett]

1682 based on heartbeats. [Paul Querna]
1684 *) mod_heartmonitor: New module to collect heartbeats, and write out a file
1685 so that other modules can load balance traffic as needed. [Paul Querna]

1688 server is online. [Paul Querna]
1690 *) mod_buffer: Honour the flush bucket and flush the buffer in the
1691 input filter. Make sure that metadata buckets are written to
1692 the buffer, not to the final brigade. [Graham Leggett]
1694 *) mod_buffer: Optimise the buffering of heap buckets when the heap
1695 buckets stay exactly APR_BUCKET_BUFF_SIZE long. [Graham Leggett,
1698 *) mod_buffer: Optional support for buffering of the input and output
1699 filter stacks. Can collapse many small buckets into fewer larger
1700 buckets, and prevents excessively small chunks being sent over
1701 the wire. [Graham Leggett]
1703 *) mod_privileges: new module to make httpd on Solaris privileges-aware
1704 and to enable different virtualhosts to run with different
1705 privileges and Unix user/group IDs [Nick Kew]
1707 *) mod_mem_cache: this module has been removed. [William Rowe]
1709 *) authn/z: Remove mod_authn_default and mod_authz_default.
1712 *) authz: Fix handling of authz configurations, make default authz
1713 logic replicate 2.2.x authz logic, and replace <Satisfy*>, Reject,
1714 and AuthzMergeRules directives with Match, <Match*>, and AuthzMerge

1753 *) mod_session_cookie, mod_session_dbd: Make sure cookies are set both
1754 within the output headers and error output headers, so that the
1755 session is maintained across redirects. [Graham Leggett]

1758 after a form login. Fixes a missing REMOTE_USER variable directly
1759 following a login. [Graham Leggett]

1762 included in the blank cookie when cookies are removed. This fixes an
1763 inability to log out when using mod_auth_form. [Graham Leggett]

1766 null value. [David Shane Holden <dpejesh apache.org>]
1768 *) core, authn/z: Determine registered authn/z providers directly in
1769 ap_setup_auth_internal(), which allows optional functions that just
1770 wrapped ap_list_provider_names() to be removed from authn/z modules.
1773 *) authn/z: Convert common provider version strings to macros.
1776 *) core: When testing for slash-terminated configuration paths in
1777 ap_location_walk(), don't look past the start of an empty string
1778 such as that created by a <Location ""> directive.
1781 *) core, mod_proxy: If a kept_body is present, it becomes safe for
1782 subrequests to support message bodies. Make sure that safety
1783 checks within the core and within the proxy are not triggered
1784 when kept_body is present. This makes it possible to embed
1785 proxied POST requests within mod_include. [Graham Leggett]
1787 *) mod_auth_form: Make sure the input filter stack is properly set
1788 up before reading the login form. Make sure the kept body filter
1789 is correctly inserted to ensure the body can be read a second
1790 time safely should the authn be successful. [Graham Leggett,

1794 hook instead of during fixups. Add a safety check to ensure the
1795 filters cannot be inserted more than once. [Graham Leggett,

1801 hop-by-hop cleansing. [Dirk-Willem van Gulik].
1803 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
1804 for both in- and out-put headers; and replace it by a single
1805 ap_cache_cacheable_headers() wrapped in a in- and out-put
1806 specific ap_cache_cacheable_headers_in()/out(). The latter
1807 which will also merge error and ensure content-type. To keep
1808 cache modules consistent with ease. This API change bumps
1809 up the minor MM by one [Dirk-Willem van Gulik].
1811 *) Move the KeptBodySize directive, kept_body filters and the
1812 ap_parse_request_body function out of the http module and into a
1813 new module called mod_request, reducing the size of the core.
1816 *) mod_dbd: Handle integer configuration directive parameters with a

1823 *) mod_auth_form: Add a module capable of allowing end users to log
1824 in using an HTML form, storing the credentials within mod_session.
1827 *) Add a function to the http filters that is able to parse an HTML
1828 form request with the type of application/x-www-form-urlencoded.

1834 *) mod_session_dbd: Add a session implementation capable of storing
1835 session information in a SQL database via the dbd interface. Useful
1836 for sites where session privacy is important. [Graham Leggett]

1839 of encrypting and decrypting sessions wherever they may be stored.
1840 Introduces a level of privacy when sessions are stored on the
1841 browser. [Graham Leggett]
1843 *) mod_session_cookie: Add a session implementation capable of storing
1844 session information within cookies on the browser. Useful for high
1845 volume sites where server bound sessions are too resource intensive.
1848 *) mod_session: Add a generic session interface to unify the different
1849 attempts at saving persistent sessions across requests.
1852 *) core, authn/z: Avoid calling access control hooks for internal requests
1853 with configurations which match those of initial request. Revert to
1854 original behaviour (call access control hooks for internal requests
1855 with URIs different from initial request) if any access control hooks or
1856 providers are not registered as permitting this optimization.
