20 connections will be accepted per process. [Stefan Fritsch]
22 *) prefork, worker, event: Rename MaxClients to MaxRequestWorkers which
23 describes more accurately what it does. [Stefan Fritsch]
25 *) rotatelogs: Add -p argument to specify custom program to invoke
26 after a log rotation. PR 51285. [Sven Ulland <sveniu ifi.uio.no>,

34 *) mod_status: Display information about asynchronous connections in the
35 server-status. PR 44377. [Stefan Fritsch]
37 *) mpm_event: If the number of connections of a process is very high, or if
38 all workers are busy, don't accept new connections in that process.
41 *) mpm_event: Process lingering close asynchronously instead of tying up
42 worker threads. [Jeff Trawick, Stefan Fritsch]
44 *) mpm_event: If MaxMemFree is set, limit the number of pools that is kept
45 around. [Stefan Fritsch]
47 *) mpm_event: Fix graceful restart aborting connections. PR 43359.

64 new context_document_root and context_prefix which provide information
65 about non-global URI-to-directory mappings (from e.g. mod_userdir or
66 mod_alias) to scripts. PR 49705. [Stefan Fritsch]
68 *) core: Add <ElseIf> and <Else> to complement <If> sections.
71 *) mod_ext_filter: Remove DebugLevel option in favor of per-module loglevel.
74 *) mod_include: Make the "#if expr" element use the new "ap_expr" expression
75 parser. The old parser can still be used by setting the new directive
76 SSILegacyExprParser. [Stefan Fritsch]
78 *) core: Add some features to ap_expr for use by mod_include: a restricted
79 mode that does not allow to bypass request access restrictions; new
80 variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an
81 alias for -U; an additional data entry in ap_expr_eval_ctx_t for use by
82 the consumer; an extensible ap_expr_exec_ctx() API that allows to use that
83 data entry. [Stefan Fritsch]
85 *) mod_include: Merge directory configs instead of one SSI* config directive
86 causing all other per-directory SSI* config directives to be reset.
89 *) mod_charset_lite: Remove DebugLevel option in favour of per-module
90 loglevel. [Stefan Fritsch]
92 *) core: Add ap_regexec_len() function that works with non-null-terminated
93 strings. PR 51231. [Yehezkel Horowitz <horowity checkpoint com>]
95 *) mod_authnz_ldap: If the LDAP server returns constraint violation,
96 don't treat this as an error but as "auth denied". [Stefan Fritsch]
98 *) mod_proxy_fcgi|scgi: Add support for "best guess" of PATH_INFO
99 for SCGI/FCGI. PR 50880, 50851. [Mark Montague <mark catseye.org>,
102 *) mod_cache: When content is served stale, and there is no means to
103 revalidate the content using ETag or Last-Modified, and we have
104 mandated no stale-on-error behaviour, stand down and don't cache.
105 Saves a cache write that will never be read.
108 *) mod_reqtimeout: Fix a timed out connection going into the keep-alive
109 state after a timeout when discarding a request body. PR 51103.

135 processes. Add end_generation hook for notification when the last
136 MPM child of a generation exits. [Jeff Trawick]
138 *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
139 process as opposed to disabling caching completely. This allows to use
140 the non-shared-memory cache as a workaround for the shared memory cache
141 not being available during graceful restarts. PR 48958. [Stefan Fritsch]
143 *) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,
144 necessary if a module (like mod_perl) registers additional modules late
145 in the startup phase. [Stefan Fritsch]
147 *) core: Prevent segfault if DYNAMIC_MODULE_LIMIT is reached. PR 51072.

171 Partial fix for PR 50824. [Stefan Fritsch]
173 *) mod_info: Dump config to stdout during startup if -DDUMP_CONFIG is
174 specified. PR 31956. [Stefan Fritsch]
176 *) Restore visibility of DEFAULT_PIDLOG to core and modules. MPM
177 helper function ap_remove_pid() added. [Jeff Trawick]

196 of bound backend LDAP connections. PR47634 [Eric Covener]
198 *) mod_cache: Make CacheEnable and CacheDisable configurable per
199 directory in addition to per server, making them work from within
200 a LocationMatch. [Graham Leggett]
202 *) worker, event, prefork: Correct several issues when built as
203 DSOs; most notably, the scoreboard was reinitialized during graceful
204 restart, such that processes of the previous generation were not
205 observable. [Jeff Trawick]
207 Changes with Apache 2.3.11
209 *) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI.
210 Win32's cscript interpreter can only use a single quote as comment char.
213 *) mod_proxy: balancer-manager now uses POST instead of GET.
216 *) core: new util function: ap_parse_form_data(). Previously,
217 this capability was tucked away in mod_request. [Jim Jagielski]
219 *) core: new hook: ap_run_pre_read_request. [Jim Jagielski]
221 *) mod_cache: When a request other than GET or HEAD arrives, we must
222 invalidate existing cache entities as per RFC2616 13.10. PR 15868.
225 *) modules: Fix many modules that were not correctly initializing if they
226 were not active during server startup but got enabled later during a
227 graceful restart. [Stefan Fritsch]
229 *) core: Create new ap_state_query function that allows modules to determine
230 if the current configuration run is the initial one at server startup,
231 and if the server is started for testing/config dumping only.
234 *) mod_proxy: Runtime configuration of many parameters for existing
235 balancers via the balancer-manager. [Jim Jagielski]
237 *) mod_proxy: Runtime addition of new workers (BalancerMember) for existing
238 balancers via the balancer-manager. [Jim Jagielski]
240 *) mod_cache: When a bad Expires date is present, we need to behave as if
241 the Expires is in the past, not as if the Expires is missing. PR 16521.
242 [Co-Advisor <coad@measurement-factory.com>]
244 *) mod_cache: We must ignore quoted-string values that appear in a
245 Cache-Control header. PR 50199. [Graham Leggett]

251 take precedence if present. PR 35247. [Graham Leggett]
253 *) mod_ssl: Fix a possible startup failure if multiple SSL vhosts
254 are configured with the same ServerName and private key file.
255 [Masahiro Matsuya <mmatsuya redhat.com>, Joe Orton]
257 *) mod_socache_dc: Make module compile by fixing some typos.
258 PR 50735 [Mark Montague <mark catseye.org>]

264 PR 50434 [Stefan Fritsch]
266 *) core: Add support to set variables with the 'Define' directive. The
267 variables that can then be used in the config using the ${VAR} syntax
268 known from envvar interpolation. [Stefan Fritsch]

271 ProxyAddHeaders defaults to On. [Vincent Deffontaines]
273 *) mod_slotmem_shm: Increase memory alignment for slotmem data.
276 *) mod_ssl: Add config options for OCSP: SSLOCSPResponderTimeout,
277 SSLOCSPResponseMaxAge, SSLOCSPResponseTimeSkew.
278 [Kaspar Brand <httpd-dev.2011 velox.ch>]
280 *) mod_ssl: Revamp output buffering to reduce network overhead for
281 output fragmented into many buckets, such as chunked HTTP responses.
284 *) core: Apply <If> sections to all requests, not only to file base requests.
285 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
286 The merging of <If> sections now happens after the merging of <Location>
287 sections, even if an <If> section is embedded inside a <Directory> or
288 <Files> section. [Stefan Fritsch]
290 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
291 and using slotmem. Create foundation for dynamic growth/changes of
292 members within a balancer. Remove BalancerNonce in favor of a
293 per-balancer 'nonce' parameter. [Jim Jagielski]
295 *) mod_status: Don't show slots which are disabled by MaxClients as open.
296 PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]
298 *) mpm_prefork: Fix ap_mpm_query results for AP_MPMQ_MAX_DAEMONS and
301 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
302 authorization directives were mixed. [Stefan Fritsch]
304 *) mod_authn_socache: change directive name from AuthnCacheProvider
305 to AuthnCacheProvideFor. The term "provider" is overloaded in
306 this module, and we should avoid confusion between the provider
307 of a backend (AuthnCacheSOCache) and the authn provider(s) for
308 which this module provides cacheing (AuthnCacheProvideFor).
311 *) mod_proxy_http: Allocate the fake backend request from a child pool
312 of the backend connection, instead of misusing the pool of the frontend
313 request. Fixes a thread safety issue where buckets set aside in the
314 backend connection leak into other threads, and then disappear when
315 the frontend request is cleaned up, in turn causing corrupted buckets
316 to make other threads spin. [Graham Leggett]
318 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
319 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
320 escape other special characters with backslashes. The old format can
321 still be used with the LegacyDNStringFormat argument to SSLOptions.
323 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
324 scripts and mod_rewrite. [Stefan Fritsch]
326 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in
327 RewriteCond. [Stefan Fritsch]
329 *) mod_rewrite: Allow to unset environment variables using E=!VAR.
330 PR 49512. [Mark Drayton <mark markdrayton info>, Stefan Fritsch]
332 *) mod_headers: Restore the 2.3.8 and earlier default for the first
333 argument of the Header directive ("onsuccess"). [Eric Covener]
335 *) core: Disallow the mixing of relative and absolute Options PR 33708.
336 [Sönke Tesch <st kino-fahrplan.de>]
338 *) core: When exporting request headers to HTTP_* environment variables,
339 drop variables whose names contain invalid characters. Describe in the
340 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
342 *) core: When selecting an IP-based virtual host, favor an exact match for
343 the port over a wildcard (or omitted) port instead of favoring the one
344 that came first in the configuration file. [Eric Covener]
346 *) core: Overlapping virtual host address/port combinations now implicitly
347 enable name-based virtual hosting for that address. The NameVirtualHost
348 directive has no effect, and _default_ is interpreted the same as "*".
351 *) core: In the absence of any Options directives, the default is now
352 "FollowSymlinks" instead of "All". [Igor Galić]
354 *) rotatelogs: Add -e option to write logs through to stdout for optional
355 further processing. [Graham Leggett]
357 *) mod_ssl: Correctly read full lines in input filter when the line is
358 incomplete during first read. PR 50481. [Ruediger Pluem]
360 *) mod_authz_core: Add AuthzSendForbiddenOnFailure directive to allow
361 sending '403 FORBIDDEN' instead of '401 UNAUTHORIZED' if authorization
362 fails for an authenticated user. PR 40721. [Stefan Fritsch]
364 Changes with Apache 2.3.10
366 *) mod_rewrite: Don't implicitly URL-escape the original query string
367 when no substitution has changed it. PR 50447. [Eric Covener]
369 *) core: Honor 'AcceptPathInfo OFF' during internal redirects,
370 such as per-directory mod_rewrite substitutions. PR 50349.
373 *) mod_rewrite: Add 'RewriteOptions InheritBefore' to put the base
374 rules/conditions before the overridden rules/conditions. PR 39313.
375 [Jérôme Grandjanny <jerome.grandjanny cea.fr>]
377 *) mod_autoindex: add IndexIgnoreReset to reset the list of IndexIgnored
378 filenames in higher precedence configuration sections. PR 24243.
381 *) mod_cgid: RLimit* directive support for mod_cgid. PR 42135
384 *) core: Fail startup when the argument to ServerName looks like a glob
385 or a regular expression instead of a hostname (*?[]). PR 39863
386 [Rahul Nair <rahul.g.nair gmail.com>]
388 *) mod_userdir: Add merging of enable, disable, and filename arguments
389 to UserDir directive, leaving enable/disable of userlists unmerged.
390 PR 44076 [Eric Covener]
392 *) httpd: When no -k option is provided on the httpd command line, the server
393 was starting without checking for an existing pidfile. PR 50350
396 *) mod_proxy: Put the worker in error state if the SSL handshake with the
397 backend fails. PR 50332.
398 [Daniel Ruggeri <DRuggeri primary.net>, Ruediger Pluem]
400 *) mod_cache_disk: Fix Windows build which was broken after renaming
401 the module. [Gregg L. Smith]
403 Changes with Apache 2.3.9
405 *) SECURITY: CVE-2010-1623 (cve.mitre.org)
406 Fix a denial of service attack against mod_reqtimeout.
409 *) mod_headers: Change default first argument of Header directive
410 from "onsuccess" to "always". [Eric Covener]
412 *) mod_include: Add the onerror attribute to the include element,
413 allowing an URL to be specified to include on error. [Graham
416 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be
417 consistent with the naming of other modules. [Graham Leggett]
419 *) mod_setenvif: Add SetEnvIfExpr directive to set env var depending on
420 expression. [Stefan Fritsch]
422 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
425 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
426 binary (Suexec Off), or force startup failure if suEXEC is required
427 but not supported (Suexec On). Change SuexecUserGroup to fail
428 startup instead of just printing a warning if suEXEC is disabled.
431 *) core: Add Error directive for aborting startup or htaccess processing
432 with a specified error message. [Jeff Trawick]
434 *) mod_rewrite: Fix the RewriteEngine directive to work within a
435 location. Previously, once RewriteEngine was switched on globally,
436 it was impossible to switch off. [Graham Leggett]
438 *) core, mod_include, mod_ssl: Move the expression parser derived from
439 mod_include back into mod_include. Replace ap_expr with a parser
440 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
441 ap_expr's public interface and provide hooks for modules to add variables
442 and functions. [Stefan Fritsch]
444 *) core: Do the hook sorting earlier so that the hooks are properly sorted
445 for the pre_config hook and during parsing the config. [Stefan Fritsch]
447 *) core: In the absence of any AllowOverride directives, the default is now
448 "None" instead of "All". PR49823 [Eric Covener]
450 *) mod_proxy: Don't allow ProxyPass or ProxyPassReverse in
451 <Directory> or <Files>. PR47765 [Eric Covener]
453 *) prefork/worker/event MPMS: default value (when no directive is present)
454 of MaxConnectionsPerChild/MaxRequestsPerChild is changed to 0 from 10000
455 to match default configuration and manual. PR47782 [Eric Covener]
457 *) proxy_connect: Don't give up in the middle of a CONNECT tunnel
458 when the child process is starting to exit. PR50220. [Eric Covener]

472 request (RFC 2616 9.6). PR 42978. [Stefan Fritsch]
474 *) mod_dav: Send 400 error if malformed Content-Range header is received for
475 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
477 *) mod_proxy: Release the backend connection as soon as EOS is detected,
478 so the backend isn't forced to wait for the client to eventually
479 acknowledge the data. [Graham Leggett]
481 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
482 per-directory, and chosen during the location walk. Make ProxyPass
483 work correctly from within a LocationMatch. [Graham Leggett]
485 *) core: Fix segfault if per-module LogLevel is on virtual host
486 scope. PR 50117. [Stefan Fritsch]
488 *) mod_proxy: Move the ProxyErrorOverride directive to have per
489 directory scope. [Graham Leggett]
491 *) mod_allowmethods: New module to deny certain HTTP methods without
492 interfering with authentication/authorization. [Paul Querna,
493 Igor Galić, Stefan Fritsch]
495 *) mod_ssl: Log certificate information and improve error message if client
496 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
499 *) htcacheclean: Teach htcacheclean to limit cache size by number of
500 inodes in addition to size of files. Prevents a cache disk from
501 running out of space when many small files are cached.
504 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
505 describes more accurately what the directive does. The old name
506 still works but logs a warning. [Stefan Fritsch]
508 *) mod_cache: Optionally serve stale data when a revalidation returns a
509 5xx response, controlled by the CacheStaleOnError directive.
512 *) htcacheclean: Allow the listing of valid URLs within the cache, with
513 the option to list entry metadata such as sizes and times. [Graham
516 *) mod_cache: correctly parse quoted strings in cache headers.
519 *) mod_cache: Allow control over the base URL of reverse proxied requests
520 using the CacheKeyBaseURL directive, so that the cache key can be
521 calculated from the endpoint URL instead of the server URL. [Graham
524 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
525 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
526 CacheMinExpire and CacheMaxExpire can be set per directory/location.
529 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and
530 CacheReadTime can be set per directory/location. [Graham Leggett]
532 *) core: Speed up config parsing if using a very large number of config
533 files. PR 50002 [andrew cloudaccess net]
535 *) mod_cache: Support the caching of HEAD requests. [Graham Leggett]
537 *) htcacheclean: Allow the option to round up file sizes to a given
538 block size, improving the accuracy of disk usage. [Graham Leggett]
540 *) mod_ssl: Add authz providers for use with mod_authz_core and its
541 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
542 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
543 'ssl-require' (expressions with same syntax as SSLRequire).
546 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
547 bison instead of yacc. [Stefan Fritsch]
549 *) mod_disk_cache: Change on-disk header file format to support the
550 link of the device/inode of the data file to the matching header
551 file, and to support the option of not writing a data file when
552 the data file is empty. [Graham Leggett]
554 *) core/mod_unique_id: Add generate_log_id hook to allow to use
555 the ID generated by mod_unique_id as error log ID for requests.
558 *) mod_cache: Make sure that we never allow a 304 Not Modified response
559 that we asked for to leak to the client should the 304 response be
560 uncacheable. PR45341 [Graham Leggett]
562 *) mod_cache: Add the cache_status hook to register the final cache
563 decision hit/miss/revalidate. Add optional support for an X-Cache
564 and/or an X-Cache-Detail header to add the cache status to the
565 response. PR48241 [Graham Leggett]
567 *) mod_authz_host: Add 'local' provider that matches connections originating
568 on the local host. PR 19938. [Stefan Fritsch]
570 *) Event MPM: Fix crash accessing pollset on worker thread when child
571 process is exiting. [Jeff Trawick]
573 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
574 pass the system library path (LD_LIBRARY_PATH or platform-specific
575 variables) along with the system PATH, by default. Both should be
576 overridden together as desired using PassEnv etc; see mod_env.
579 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
580 capture a stale backend response, perform If-Modified-Since requests
581 against the backend, and serving from the cache all 304 responses.
582 This restores pre-2.2.4 cache behavior. [William Rowe]
584 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
585 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop

606 *) mod_cache: Add a discrete commit_entity() provider function within the
607 mod_cache provider interface which is called to indicate to the
608 provider that caching is complete, giving the provider the opportunity
609 to commit temporary files permanently to the cache in an atomic
610 fashion. Replace the inconsistent use of error cleanups with a formal
611 set of pool cleanups attached to a subpool, which is destroyed on error.
614 *) mod_cache: Change the signature of the store_body() provider function
615 within the mod_cache provider interface to support an "in" brigade

618 passed to it, rather than the whole brigade as was required before.

1680 *) mod_auth_form: Add a module capable of allowing end users to log
1681 in using an HTML form, storing the credentials within mod_session.
1684 *) Add a function to the http filters that is able to parse an HTML
1685 form request with the type of application/x-www-form-urlencoded.
1688 *) mod_session_crypto: Initialise SSL in the post config hook.
1689 [Ruediger Pluem, Graham Leggett]
1691 *) mod_session_dbd: Add a session implementation capable of storing
1692 session information in a SQL database via the dbd interface. Useful
1693 for sites where session privacy is important. [Graham Leggett]
1695 *) mod_session_crypto: Add a session encoding implementation capable
1696 of encrypting and decrypting sessions wherever they may be stored.
1697 Introduces a level of privacy when sessions are stored on the
1698 browser. [Graham Leggett]
1700 *) mod_session_cookie: Add a session implementation capable of storing
1701 session information within cookies on the browser. Useful for high
1702 volume sites where server bound sessions are too resource intensive.
1705 *) mod_session: Add a generic session interface to unify the different
1706 attempts at saving persistent sessions across requests.
1709 *) core, authn/z: Avoid calling access control hooks for internal requests
1710 with configurations which match those of initial request. Revert to
1711 original behaviour (call access control hooks for internal requests
1712 with URIs different from initial request) if any access control hooks or
1713 providers are not registered as permitting this optimization.
1714 Introduce wrappers for access control hook and provider registration
1715 which can accept additional mode and flag data. [Chris Darroch]
1717 *) Introduced ap_expr API for expression evaluation.
1718 This is adapted from mod_include, which is the first module
1722 *) mod_authz_dbd: When redirecting after successful login/logout per
1723 AuthzDBDRedirectQuery, do not report authorization failure, and use
1724 first row returned by database query instead of last row.
1727 *) mod_ldap: Correctly return all requested attribute values
1728 when some attributes have a null value.

1737 *) Activate mod_cache, mod_file_cache and mod_disk_cache as part of the
1738 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
1739 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
1741 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
1742 contain public function declarations which are useful for
1743 third party module authors. PR 42431 [Dirk-Willem van Gulik].
1745 *) mod_dir, mod_negotiation: pass the output filter information
1746 to newly created sub requests; as these are later on used
1747 as true requests with an internal redirect. This allows for
1748 mod_cache et.al. to trap the results of the redirect.
1749 [Dirk-Willem van Gulik, Ruediger Pluem]
1751 *) mod_ldap: Add support (taking advantage of the new APR capability)
1752 for ldap rebind callback while chasing referrals. This allows direct
1753 searches on LDAP servers (in particular MS Active Directory 2003+)
1754 using referrals without the use of the global catalog.
1755 PRs 26538, 40268, and 42557 [Paul J. Reder]
1757 *) ApacheMonitor.exe: Introduce --kill argument for use by the
1758 installer. This will permit the installation tool to remove
1759 all running instances before attempting to remove the .exe.
1762 *) mod_ssl: Add support for OCSP validation of client certificates.
1763 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
1765 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
1767 *) core: Add the option to keep aside a request body up to a certain
1768 size that would otherwise be discarded, to be consumed by filters
1769 such as mod_include. When enabled for a directory, POST requests
1770 to shtml files can be passed through to embedded scripts as POST
1771 requests, rather being downgraded to GET requests. [Graham Leggett]

1812 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
1814 *) The LockFile directive, which specifies the location of
1815 the accept() mutex lockfile, is deprecated. Instead, the
1816 AcceptMutex directive now takes an optional lockfile
1817 location parameter, ala SSLMutex. [Jim Jagielski]
1819 *) mod_authn_dbd: Export any additional columns queried in the SQL select
1820 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
1821 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
1823 *) mod_dbd: Key the storage of prepared statements on the hex string
1824 value of server_rec, rather than the server name, as the server name
1825 may change (eg when the server name is set) at any time, causing
1826 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
1828 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
1830 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
1831 the first bucket from the brigade, finds it not to be a FILE
1832 bucket and barfs. The fix is to pass a bucket rather than a brigade.

1835 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
1837 *) ap_get_server_version() has been removed. Third-party modules must
1838 now use ap_get_server_banner() or ap_get_server_description().
1841 *) All MPMs: Introduce a check_config phase between pre_config and
1842 open_logs, to allow modules to review interdependent configuration
1843 directive values and adjust them while messages can still be logged
1844 to the console. Handle relevant MPM directives during this phase
1845 and format messages for both the console and the error log, as
1846 appropriate. [Chris Darroch]
1848 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
1849 to circumvent the symbolic link checks imposed by FollowSymLinks and
1850 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]

1853 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
1854 The default is none as this is far greater debugging resolution than
1855 the typical administrator is prepared to untangle. [William Rowe]
1857 *) mod_disk_cache: If possible, check if the size of an object to cache is
1858 within the configured boundaries before actually saving data.

1881 *) mod_charset_lite: Remove Content-Length when output filter can
1882 invalidate it. Warn when input filter can invalidate it.
1885 *) Authz: Add the new module mod_authn_core that will provide common
1886 authn directives such as 'AuthType', 'AuthName'. Move the directives
1887 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1888 into mod_authn_core. [Brad Nicholes]
1890 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1891 into the new module mod_access_compat which can be loaded to provide
1892 support for these directives.
1895 *) Authz: Move the 'Require' directive from the core module as well as
1896 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1897 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1898 logic into the authorization processing. [Brad Nicholes]
1900 *) Authz: Add the new module mod_authz_core which acts as the
1901 authorization provider vector and contains common authz
1902 directives. [Brad Nicholes]
1904 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1905 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1907 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1908 host-based access control provided by mod_authz_host and invoked
1909 through the 'Require' directive. [Brad Nicholes]
1911 *) Authz: Convert all of the authz modules from hook based to
1912 provider based. [Brad Nicholes]
1914 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
1915 seconds to cache a document.

1921 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1923 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1925 *) Added an End-Of-Request bucket type. The logging of a request and
1926 the freeing of its pool are now done when the EOR bucket is destroyed.
1927 This has the effect of delaying the logging until right after the last
1928 of the response is sent; ap_core_output_filter() calls the access logger
1929 indirectly when it destroys the EOR bucket. [Brian Pane]
1931 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1932 and the format of statistical output has changed. [Colm MacCarthaigh]
1934 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1936 *) Added new connection states for handler and write completion
1939 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1942 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1943 allowing string-valued client certificate attributes to be used for
1944 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
