24 *) mod_ssl: Correctly restore SSL verify state after TLSv1.3 PHA failure.
25 [Michael Kaufmann <mail michael-kaufmann.ch>]

29 <https://github.com/icing/mod_md/issues/117>. [Stefan Eissing]
31 *) Merge consecutive slashes in URL's. Opt-out with `MergeSlashes OFF`.
34 *) mod_proxy/ssl: Cleanup per-request SSL configuration anytime a backend
35 connection is recycled/reused to avoid a possible crash with some SSLProxy
36 configurations in <Location> or <Proxy> context. PR 63256. [Yann Ylavic]
38 *) mod_mime: Add `MimeOptions` directive to allow Content-Type or all metadata
39 detection to use only the last (right-most) file extension or to be
40 disabled per-dir. [Eric Covener]
42 *) MPMs unix: bind the bucket number of each child to its slot number, for a
43 more efficient per bucket maintenance. [Yann Ylavic]
45 *) http: Fix possible empty response with mod_ratelimit for HEAD requests.
46 PR 63192. [Yann Ylavic]

51 *) mod_reqtimeout: Allow to configure (TLS-)handshake timeouts.
52 PR 61310. [Yann Ylavic]
54 *) mod_auth_digest: Fix a race condition. Authentication with valid credentials could be
55 refused in case of concurrent accesses from different users.
56 PR 63124 [Simon Kappel <simon.kappel axis.com>]
58 *) mod_ssl: Don't unset FIPS mode on restart unless it's forced by
59 configuration (SSLFIPS on) and not active by default in OpenSSL.
60 PR 63136. [Yann Ylavic]
62 *) mod_ssl: give mod_md the chance to override certificate after ALPN protocol
63 negotiation. [Stefan Eissing]
65 *) mod_proxy_wstunnel: Fix websocket proxy over UDS.
66 PR 62932 <pavel dcmsys.com>
68 *) mod_negociation: LanguagePriority should be case-insensitive in order to
69 match AddLanguage behavior. PR 39730 [Christophe Jaillet]
71 *) mod_session: Always decode session attributes early. [Hank Ibell]
73 *) core: Incorrect values for environment variables are substituted when
74 multiple environment variables are specified in a directive. [Hank Ibell]
76 *) core: Split out the ability to parse wildcard files and directories
77 from the Include/IncludeOptional directives into a generic set of
78 functions ap_dir_nofnmatch() and ap_dir_fnmatch(). [Graham Leggett]
80 *) mod_dav: Fix an unlikely time-window where some incorrect data could be returned
81 from a PROPFIND request [Ruediger Pluem]
83 *) mod_ssl: Fix mod_authz provider for "require ssl" directive to check correctly
84 on HTTP/2 connections. Fixes PR 62654. [Stefan Eissing]
86 *) mod_ssl: clear *SSL errors before loading certificates and checking
87 afterwards. Otherwise errors are reported when other SSL using modules
88 are in play. Fixes PR 62880. [Michael Kaufmann]
90 *) mod_ssl: Correctly merge configurations that have client certificates set
91 by SSLProxyMachineCertificate{File|Path}. [Ruediger Pluem]
93 *) core: Ensure that aborted connections are logged as such. PR 62823
94 [Arnaud Grandville <contact@grandville.net>]
96 *) mpm_event: Stop issuing AH00484 "server reached MaxRequestWorkers..." when
97 there are still idle threads available. When there are less idle threads than
98 MinSpareThreads, issue new one-time message AH10159. Matches worker MPM.
101 *) mod_proxy_scgi, mod_proxy_uwsgi: improve error handling when sending the
102 body of the response. [Jim Jagielski]
104 *) mod_session_cookie: avoid duplicate Set-Cookie header in the response.
105 [Emmanuel Dreyfus <manu@netbsd.org>, Luca Toscano]
107 *) mod_dav_fs: Set a default DAVLockDB within the state directory.
110 *) core: Add DefaultStateDir and layout-specific state directory
111 created at "make install". [Joe Orton]
113 *) mod_ssl: Fix a regression that the configuration settings for verify mode
114 and verify depth were taken from the frontend connection in case of
115 connections by the proxy to the backend. PR 62769. [Ruediger Pluem]
117 *) ab: Add client certificate support. [Graham Leggett]
119 *) mod_proxy_hcheck: Fix issues with TCP health checks. PR 61499
120 [Dominik Stillhard <dominik.stillhard united-security-providers.ch>]
122 *) MPMs: Initialize all runtime/asynchronous objects on a dedicated pool and
123 before signals handling to avoid lifetime issues on restart or shutdown.
124 PR 62658. [Yann Ylavic]
126 *) core: Add StrictHostCheck to allow ucnonfigured hostnames to be
127 rejected. [Eric Covener]
129 *) mod_status: Cumulate CPU time of exited child processes in the
130 "cu" and "cs" values. Add CPU time of the parent process to the
134 *) mod_status: Add cumulated response duration time in milliseconds.
137 *) mod_status: Complete the data shown for async MPMs in "auto" mode.
138 Added number of processes, number of stopping processes and number
139 of busy and idle workers. [Rainer Jung]
141 *) mod_proxy: Improve the balancer member data shown in mod_status when
142 "ProxyStatus" is "On": add "busy" count and show byte counts in auto
143 mode always in units of kilobytes. [Rainer Jung]
145 *) mod_proxy: If ProxyPassReverse is used for reverse mapping of relative
146 redirects, subsequent ProxyPassReverse statements, whether they are
147 relative or absolute, may fail. PR 60408. [Peter Haworth <pmh1wheel gmail.com>]
149 *) mod_ratelimit: Don't interfere with "chunked" encoding, fixing regression
150 introduced in 2.4.34. PR 62568. [Yann Ylavic]
152 *) mod_proxy_http: forward 100-continue, and minimize race conditions when
153 reusing backend connections. PR 60330. [Yann Ylavic, Jean-Frederic Clere]
155 *) mod_proxy: Remove load order and link dependency between mod_lbmethod_*
156 modules and mod_proxy. PR 62557. [Ruediger Pluem, William Rowe]
158 *) mod_md: more robust handling of http-01 challenges and hands-off when module
159 should not be involved, e.g. challenge setup by another ACME client. [Stefan Eissing]
161 *) ru, zh-cn and zh-tw translations of errordocs have been added.
162 Contributed by Alexander Gaganashvili and CodeingBoy
164 *) mod_userdir: If several directories are given in a UserDir directive, only files
165 in the first existing one are checked. If the file is not found there, the
166 other possible directories are not checked. The doc clearly states that they
167 will be checked one by one, until a match is found or an external redirect is
171 *) mod_rewrite: Only create the global mutex used by "RewriteMap prg:" when
172 this type of map is present in the configuration. PR62311.
173 [Hank Ibell <hwibell gmail.com>]
175 *) mod_ldap: Abort on LDAP locking errors. [Eric Covener]
177 *) mod_ssl: Support loading certificates and private keys from the
178 PKCS#11 OpenSSL engine. [Anderson Sasaki <ansasaki redhat.com>,
181 *) http: LimitRequestBody applies to proxied requests. [Yann Ylavic]
183 *) mod_logio: Add LogIOTrackTTFU and %^FU logformat to log the time
184 difference between request start and last request body byte read (finished upload).
187 *) mod_ssl: add support for TLSv1.3 (tested with OpenSSL v1.1.1-pre4, other libs may
188 need more sugar). SSL(Proxy)CipherSuite now has an optional first parameter for the
189 protocol the ciphers are for.
190 Directive "SSLVerifyClient" now triggers certificate retrieval from the client (this
191 is not fully tested - but fails in similar fashion as in TLSv1.2 in my setups).
192 Verifying the client fails exactly the same for HTTP/2 connections for all SSL protocols,
193 as this would need to trigger the master connection thread - which we do not support
195 Renegotiation of ciphers is intentionally ignored for TLSv1.3 connections. "SSLCipherSuite"
196 does not allow to specify TLSv1.3 ciphers in a directory context (because it cannot work) and
197 TLSv1.2 or lower ciphers are not relevant, as cipher suites are completely separate.
198 This means there is a bit if a world split when simultaneously having TLSv1.2 and TLSv1.3
199 connections to the same server.
200 [Yann Ylavic, Stefan Eissing]
202 *) mod_ssl: proper checks for libressl 2.07/8 and its TLSv1_3 support, see PR 62236.
203 [Bernard Spil <brnrd@freebsd.org>]
205 *) mod_cgi: Add CGIScriptTimeout to make mod_cgi's timeout per-directory and
206 independent of the core Timeout directive. PR 62229.
207 [Hank Ibell <hwibell gmail.com>]
209 *) mod_ssl: heavily simplified SSLPolicy. No more user defines, no propxy policies,
210 just the basic "modern", "intermediate" and "old" as specified by Mozilla security.
213 *) mod_md: fixes error in renew window calculation that may lead to mod_md running
214 watchdog in a tight loop until actual renewal becomes necessary. [Stefan Eissing]
216 *) mod_md: /.well-known/acme-challenge requests that cannot be answered for hostnames
217 outside the configured MDs are free to be answered by other handlers. This allows
218 co-existance between mod_md and other ACME clients on the same server (implements PR62189).
219 [Stefan Eissing, Arkadiusz Miskiewicz <arekm@maven.pl>]
221 *) core: Create a conn_config_t structure to hold an extendable core config rather
222 than consuming the whole pointer with the connection socket. [Graham Leggett]
224 *) core: adding AP_DECLARE for ap_parse_vhost_addrs() and minor bumb mmn. Resolves
225 building mod_ssl on Windows. [Stefan Eissing, Gregg Smith]
227 *) core: adding defines to allow interworking with honggfuzz without
228 further patches. [Stefan Eissing, Robert Swiecki]
230 *) mod_headers: 'RequestHeader set|edit|edit_r Content-Type X' could
231 inadvertently modify the Content-Type _response_ header. Applies to
232 Content-Type only and likely to only affect static file responses.
235 *) mod_cgi: Improve AH01215 messages to make it more clear that the message is
236 the CGI scripts stderr output. PR 61980. [Hank Ibell <hwibell gmail.com>]
238 *) mod_headers: Allow 'Header unset Content-Type' to remove the Content-Type
239 header. PR 61983. [Hank Ibell <hwibell gmail.com>]
241 *) mod_md v1.1.8: new configuration directive "MDBaseServer on|off" to allow/inhibit
242 management of the base server domains outside VirtualHosts. By default, this is "off",
243 e.g. mod_md will not manage certificates or perform https: redirections on the
244 base server. [Stefan Eissing]
246 *) core: Add "AcceptErrorsNonFatal" to allow ECONNREFUSED, ECONNABORTED, and
247 ECONNRESET during the client accept() to not trigger graceful shutdown of
248 the child process. [Eric Covener]
251 - MDMustStaple was unable to create the necessary OpenSSL OBJ identifier on some platforms,
252 possibly because this fails if the OID is already configured in ```openssl.cnf```, see
253 [here](https://github.com/openssl/openssl/issues/2795).
254 - Two memory leaks in cert issuer and alt-names lookup eliminated by Yann Ylavic.
255 - Changing MDMustStaple triggers certificate renewal.
256 - More verbosity when *not* handing out certificates, e.g. mod_ssl asks, but mod_md has no
257 idea what it is talking about. Some people report misbehaviour here.
258 - Re-enabled support for md_get_credentials() function that was used in older mod_ssl
259 patch, so that people with old patched servers get a chance to upgrade.
260 [Stefan Eissing, Yann Ylavic]
262 *) mod_susbtitute: Allow expressions in the subtitution, prefixed with expr=
265 *) mod_md: fixed mem pool usage for auto-added server names. Added
266 error logging of exact ACME response when challenges failed.
269 *) mod_md: reverses most of v1.0.5 optimization of post_config init, so that
270 mod_ssl can ask for certiticates without crashing. [Stefan Eissing]
272 *) mod_proxy: allow SSLProxyCheckPeer* usage for all proxy modules.
273 PR 61857. [Yann Ylavic]
275 *) mod_proxy_html: fix handling of <meta http-equiv> elements.
278 *) mod_md: fixed backward compatibility to old <ManagedDomain configuration.
279 Add higher level WARNING log when initial request to ACME server fails, mentioning
280 some advice. [Stefan Eissing]
282 *) mod_md: name change in configuration directives. The old names are still working
283 in this version, so you can safely upgrade. They will give warnings in the log and
284 will disappear in the immediate future. ManagedDomain is now MDomain,
285 <ManagedDomain> is now <MDomainSet>. [Stefan Eissing]
287 *) mod_ssl: renamed section <SSLPolicy to <SSLPolicyDefine. Fixed behaviour
288 for new server config merge flag. Denying global, only once used directives
289 inside a SSLPolicyDefine. [Stefan Eissing]
291 *) mod_auth_basic: Be less tolerant when parsing the credencial. Only spaces
292 should be accepted after the authorization scheme. \t are also tolerated.
295 *) core: Support zone/scope in IPv6 link-local addresses in Listen and
296 VirtualHost directives (requires APR 1.7.x or later). PR 59396. [Joe Orton]
298 *) mod_md: v1.0.5, restricting post_config dry run to be more silent and performing
299 only necessary work for mod_ssl to be also happy with the configuration.
302 *) mod_md: v1.0.4, removed the 'a2md' utility command from build. Only used in github
303 testing. Avoid problems with our build system that had problems after the latest
304 changes to make a clean initial build. Remove the windows a2md.dsp therefore also.
307 *) mod_ssl: Fail with 403 if the username for FakeBasicAuth mode
308 includes a colon character. PR 52644. [Joe Orton]
310 *) mod_md: v1.0.3, fixed various bugs in persisting job properties, so that status is
311 persisted accross child process changes and staging is reset on reloads. Changed
312 MDCertificateAgreement url checks. As long as the CA reports that the account has
313 an agreement, no further checking is done. Existing accounts need no changes when
314 a new agreement comes out. [Stefan Eissing]
316 *) mod_watchdog: Correct some log messages. [Rainer Jung]
318 *) mod_noloris: complete build setup. [Rainer Jung]
320 *) mod_md: fix static compilation. [Rainer Jung]
322 *) mod_md: fix compilation of helper binary a2md. [Rainer Jung]
324 *) core: fix pcre feature detection in configure when using pcre2. [Rainer Jung]
326 Changes with Apache 2.5.0-alpha
328 *) mod_md: v1.0.1, ServerName/Alias names from pure-http: virtual hosts are no longer
329 auto-added to a Managed Domain. Error counts of jobs are presisted. When the server
330 restarts (gracefully) any errored staging areas are purged to reset the signup/renewal
331 process. [Stefan Eissing]
333 *) mod_md: v1.0.0, new config directive 'MDNotifyCmd' to hook in a program when Managed
334 Domains have obtained/renewed their certificates successfully. [Stefan Eissing]
336 *) mod_md: v0.9.9, fix for applying challenge type based on available ports. [Stefan Eissing]
339 - Use of the new module flag
340 - Removed obsolete function from interface to mod_ssl.
341 - Fallback certificates has version set and no longer claims to be a CA. (re issue #32)
342 - MDRequireHttps now happens before any Redirect.
345 *) mod_ssl: unshare SSLSrvConfigRec instances between base server and virtual hosts. This avoids
346 overwrites of later initializattions (vhost_id), selective disables by "SSLEngine addr-list"
347 and certificate/key pickup from mod_md. [Stefan Eissing]
349 *) mod_md: v0.9.6: a "MDRequireHttps permament" configured domain automatically sends out
350 HSTS (rfc 6797) headers in https: responses. [Stefan Eissing]
352 *) mod_ssl: adding ssl_policies.h[.in] for policy cipher/protocol definitions. Use
353 update_policies.py to update manually from Mozilla JSON definitions at
354 https://statics.tls.security.mozilla.org/server-side-tls-conf.json
358 - New directive (srly: what do you expect at this point?) "MDMustStaple on|off" to control if
359 new certificates are requested with the OCSP Must Staple extension.
360 - Known limitation: when the server is configured to ditch and restart child processes, for example
361 after a certain number of connections/requests, the mod_md watchdog instance might migrate
362 to a new child process. Since not all its state is persisted, some messsages might appear a
363 second time in the logs.
364 - Adding checks when 'MDRequireHttps' is used. It is considered an error when 'MDPortMap 443:-'
365 is used - which negates that a https: port exists. Also, a warning is logged if no
366 VirtualHost can be found for a Managed Domain that has port 443 (or the mapped one) in
368 - New directive 'MDRequireHttps' for redirecting http: traffic to a Managed Domain, permanently
370 - Fix for using a fallback certificate on initial signup of a Managed Domain. Requires also
371 a changed mod_ssl patch (v5) to take effect.
372 - compatibility with libressl
375 *) mod_md: v0.9.2: new directive 'MDHttpProxy' to define a proxy for outgoing connection,
376 some minor bugfixes, twiddle the build system to avoid non-pic code generation.
380 - various fixes in MDRenewWindow handling when specifying percent. Serialization changed. If
381 someone already used percent configurations, it is advised to change these to a new value,
382 reload and change back to the wanted ones.
383 - various fixes in handling of MDPrivateKeys when specifying 2048 bits (the default) explicitly.
384 - mod_md version removed from top level md_store.json file. The store has its own format version
385 to facilitate upgrades.
389 Certificate provisioning from Let's Encrypt (and other ACME CAs) for mod_ssl virtual hosts.
392 *) mod_ssl: add SSLPolicy (define/use) and SSLProxyPolicy directives plus documentation. Add
393 core definitions for policies 'modern', 'intermediate' and 'old', as defined by Mozilla
394 in <https://wiki.mozilla.org/Security/Server_Side_TLS>. [Stefan Eissing]
396 *) mod_md: new module for managing domains across VirtualHosts with ACME protocol
397 implementation for automated certificate signup and renewal. Default CA is
398 the test area of Let's Encrypt right now, so certificates root will not be valid.
399 Will be switched to the real service endpoint rather soon. If you need it now,
400 configure 'MDCertificateAuthority https://acme-v01.api.letsencrypt.org/directory'.
403 *) mod_rewrite: Add 'RewriteOptions LongURLOptimization' to free memory
404 from each set of unmatched rewrite conditions.
407 *) Allow the argument to <IfFile>, <IfDefine>, <IfSection>, <IfDirective>,
408 and <IfModule> to be quoted. This is primarily for the benefit of
409 <IfFile>. [Eric Covener]
411 *) Introduce request taint checking framework to prevent privilege
412 hijacking through .htaccess. [Nick Kew]
414 *) Add <IfDirective> and <IfSection> directives. [Joe Orton]
416 *) When using mod_status with the Event MPM, report the number of requests
417 associated with an active connection in the "ACC" field. Previously
418 zero was always reported with this MPM. PR60647. [Eric Covener]
420 *) mod_proxy_wstunnel: Reliably run before mod_proxy_http.
423 *) http: Allow unknown response status' lines returned in the form of
424 "HTTP/x.x xxx Status xxx". [Yann Ylavic]
426 *) core: Add <IfFile> configuration section to allow any file on disk to be
427 used as a conditional. [Edward Lu, Eric Covener]
429 *) mod_crypto: Add the all purpose crypto filters with support for HLS.
432 *) core: Drop an invalid Last-Modified header value coming
433 from a FCGI/CGI script instead of replacing it with Unix epoch.
434 Warn the users about Last-Modified header value replacements
435 and violations of the RFC.
436 [Yann Ylavic, Luca Toscano, William Rowe, Jacob Champion]
438 *) mod_dav: Allow other modules to become providers and add ACLs
440 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
442 *) mod_dav: Add dav_begin_multistatus, dav_send_one_response,
443 dav_finish_multistatus, dav_send_multistatus, dav_handle_err,
444 dav_failed_proppatch, dav_success_proppatch to mod_dav.h.
445 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
447 *) core: explicitly exclude 'h2' from protocols announced via an Upgrade:
448 header as commanded by http-wg. [Stefan Eissing]
450 *) mod_proxy_ajp: Add "secret" parameter to proxy workers to implement legacy
451 AJP13 authentication. PR 53098. [Dmitry A. Bakshaev <dab1818 gmail com>]
453 *) mpm: Generalise the ap_mpm_register_socket functions to accept pipes
454 or sockets. [Graham Leggett]
456 *) core: Extend support for setting aside data from the network input filter
457 to any connection or request input filter. [Graham Leggett]
459 *) core: Split ap_create_request() from ap_read_request(). [Graham Leggett]
461 *) mod_auth_digest: Fix compatibility with expression-based Authname. PR59039.
464 *) mpm: Add a complete_connection hook that confirms whether an MPM is allowed
465 to leave the WRITE_COMPLETION phase. Move filter code out of the MPMs.
468 *) mod_cache: Consider Cache-Control: s-maxage in expiration
469 calculations. [Eric Covener]
471 *) mod_cache: Allow caching of responses with an Expires header
472 in the past that also has Cache-Control: max-age or s-maxage.
473 PR55156. [Eric Covener]
475 *) mod_session: Introduce SessionExpiryUpdateInterval which allows to
476 configure the session/cookie expiry's update interval. PR 57300.
477 [Paul Spangler <paul.spangler ni.com>]
479 *) core: Extend support for asynchronous write completion from the
480 network filter to any connection or request filter. [Graham Leggett]
482 *) mod_auth_digest: remove AuthDigestEnableQueryStringHack which is no
483 more documented since dec 2012 (r1415960). [Christophe Jaillet]
485 *) mod_charset_lite: On EBCDIC platforms, make sure mod_charset_lite runs
486 after other resource-level filters. [Eric Covener]
488 *) http: Don't remove the Content-Length of zero from a HEAD response if
489 it comes from an origin server, module or script. [Yann Ylavic]
491 *) http: Add support for RFC2324/RFC7168. [Graham Leggett]
493 *) mod_authn_core: Add expression support to AuthName and AuthType.
496 *) suexec: Filter out the HTTP_PROXY environment variable because it is
497 treated as alias for http_proxy by some programs. [Stefan Fritsch]
499 *) mod_proxy_http: Don't establish or reuse a backend connection before pre-
500 fetching the request body, so to minimize the delay between it is supposed
501 to be alive and the first bytes sent: this is a best effort to prevent the
502 backend from closing because of idle or keepalive timeout in the meantime.
503 Also, handle a new "proxy-flushall" environment variable which allows to
504 flush any forwarded body data immediately. PR 56541+37920. [Yann Ylavic]
506 *) core: Define and UnDefine are no longer permitted in
507 directory context. Previously they would always be evaulated
508 as the configuration was read without regard for the directory
509 context. [Eric Covener]
511 *) config: For directives that do not expect any arguments, enforce
512 that none are specified in the configuration file.
513 [Joachim Zobel <jzobel heute-morgen.de>, Eric Covener]
515 *) mod_rewrite: Improve 'bad flag delimeters' startup error by showing
516 how the input was tokenized. PR 56528. [Edward Lu <Chaosed0 gmail.com>]
518 *) mod_proxy: Don't put non balancer-member workers in error state by
519 default for connection or 500/503 errors, and honor status=+I for
520 any error. PR 48388. [Yann Ylavic]
522 *) ap_expr: Add filemod function for checking file modification dates
525 *) mod_authnz_ldap: Resolve crashes with LDAP authz and non-LDAP authn since
526 r1608202. [Eric Covener]
528 *) apreq: Content-Length header should be always interpreted as a decimal.
529 Leading 0 could be erroneously considered as an octal value. PR 56598.
530 [Chris Card <ctcard hotmail com>]
532 *) mod_proxy: Now allow for 191 character worker names, with non-fatal
533 errors if name is truncated. PR53218. [Jim Jagielski]
535 *) mod_ssl: Add optional function "ssl_get_tls_cb" to allow support
536 for channel bindings. [Simo Sorce <simo redhat.com>]
538 *) mod_proxy_wstunnel: Concurrent websockets messages could be
539 lost or delayed with ProxyWebsocketAsync enabled.
540 [Edward Lu <Chaosed0 gmail.com>]
542 *) core, mod_info: Add compiled and loaded PCRE versions to version
543 number display. [Rainer Jung]
545 *) mod_authnz_ldap: Return LDAP connections to the pool before the handler
546 is run, instead of waiting until the end of the request. [Eric Covener]

563 *) Add the ldap-search option to mod_authnz_ldap, allowing authorization
564 to be based on arbitrary expressions that do not include the username.
567 *) Add the ldap function to the expression API, allowing LDAP filters and
568 distinguished names based on expressions to be escaped correctly to
569 guard against LDAP injection. [Graham Leggett]

596 neither GET nor POST, such as for DAV requests. PR 54914. [Chris Darroch]
598 *) mod_rewrite: Rename the handler that does per-directory internal
599 redirects to "rewrite-redirect-handler" from "redirect-handler" so
600 it is less ambiguous and less likely to be reused. [Eric Covener]
602 *) mod_rewrite: Protect against looping with the [N] flag by enforcing a
603 default limit of 10000 iterations, and allowing each rule to change its
604 limit. [Eric Covener]
606 *) mod_ssl: Fix config merging of SSLOCSPEnable and SSLOCSPOverrideResponder.
609 *) Add HttpContentLengthHeadZero and HttpExpectStrict directives.

617 to support write completion. [Graham Leggett]
619 *) core: Add parse_errorlog_arg callback to ap_errorlog_provider
620 to allow providers to check the ErrorLog argument. [Jan Kaluza]

632 *) ldap: Support ldaps when using the Microsoft LDAP SDK.
633 PR 54626. [Jean-Frederic Clere]
635 *) mod_authnz_ldap: Change default value of AuthLDAPMaxSubGroupDepth to 0
636 to avoid performance problems when subgroups aren't in use. [Eric Covener]
638 *) mod_syslog: New module implementing syslog ap_error_log provider.
639 Previously, this code was part of core, now it's in separate module.
642 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
643 syslog support from core to new mod_syslog. [Jan Kaluza]
645 *) mod_status, mod_echo: Fix the display of client addresses.
646 They were truncated to 31 characters which is not enough for IPv6 addresses.
647 This is done by deprecating the use of the 'client' field and using
648 the new 'client64' field in worker_score.

657 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
660 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
661 been configured with -D Z_PREFIX, which redefines the token "deflate".
664 *) mod_auth_digest: Use the secret when generating nonces in all cases and
665 not only when AuthName is used in .htaccess files (this change may cause
666 problems if used with round robin load balancers). Don't regenerate the
667 secret on graceful restarts. PR 54637 [Stefan Fritsch]
669 *) core: Stop the HTTP_IN filter from attempting to write error buckets
670 to the output filters, which is bogus in the proxy case. Create a
671 clean mapping from APR codes to HTTP status codes, and use it where
672 needed. [Graham Leggett]
674 *) mod_proxy: Ensure network errors detected by the proxy are returned as
675 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
676 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.

688 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
689 Cache the result of the most recent password hash verification for every
690 keep-alive connection. This saves some expensive calculations.
693 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
694 MSIE 3. [Stefan Fritsch]
696 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
697 conformance or to only log the found problems. [Stefan Fritsch]
701 *) core: Add LogLevelOverride directive that allows to override the
702 loglevel for clients from certain IPs. This also works for things
703 like the SSL handshake where <If> LogLevel ... </If> is evaluated
704 too late. [Stefan Fritsch]
706 *) core: Add new directive Warning to issue warnings from a configuration
707 file. Both Warning and Error now generate a timestamped log message.
710 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
711 variables. [Stefan Fritsch]
713 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
