2 Changes with Apache 2.5.1
4 *) mod_proxy_http: Fix 100-continue deadlock for spooled request bodies,
5 leading to Request Timeout (408). PR 63855. [Yann Ylavic]
7 *) mod_md: Adding the several new features.
8 The module offers an implementation of OCSP Stapling that can replace fully or
9 for a limited set of domains the existing one from mod_ssl. OCSP handling
10 is part of mod_md's monitoring and message notifications. If can be used
11 for sites that do not have ACME certificates.
12 The url for a CTLog Monitor can be configured. It is used in the server-status
13 to link to the external status page of a certicate.
14 The MDMessageCmd is called with argument "installed" when a new certificate
15 has been activated on server restart/reload. This allows for processing of
16 the new certificate, for example to applications that require it in different
21 *) mod_deflate, mod_brotli: honor "Accept-Encoding: foo;q=0" as per RFC 7231; which
22 means 'foo' is "not acceptable". PR 58158 [Chistophe Jaillet]
24 *) mod_proxy: Fix crash by resolving pool concurrency problems. PR 63503
25 [Ruediger Pluem, Eric Covener]
27 *) core: On Windows, fix a start-up crash if <IfFile ...> is used with a path that is not
28 valid (For example, testing for a file on a flash drive that is not mounted)
31 *) mod_proxy_balancer: Fix case-sensitive referer check related to CSRF/XSS
32 protection. PR63688. [Armin Abfalterer <a.abfalterer gmail.com>]
34 *) mod_authn_socache: Increase the maximum length of strings that can be cached by
35 the module from 100 to 256. PR 62149 [<thorsten.meinl knime.com>]
37 *) mod_ssl: reverting a 2.4.40 change where a superfluous SSLCertificateChainFile configuration
38 for a domain managed by mod_md caused a startup error. This happened when mod_md installed
39 its fallback certificate, before it got the first real certificate from Lets Encrypt.
42 *) core, mod_rewrite: Set PCRE_DOTALL by default. Revert via
43 RegexDefaultOptions -DOTALL [Yann Ylavic]
45 *) core: Remove request details from built-in error documents [Eric Covener]
47 *) mod_http2: core setting "LimitRequestFieldSize" is not additionally checked on
48 merged header fields, just as HTTP/1.1 does. [Stefan Eissing, Michael Kaufmann]
50 *) mod_http2: fixed a bug that prevented proper stream cleanup when connection
51 throttling was in place. Stream resets by clients on streams initiated by them
52 are counted as possible trigger for throttling. [Stefan Eissing]
54 *) mod_http2/mpm_event: Fixes the behaviour when a HTTP/2 connection has nothing
55 more to write with streams ongoing (flow control block). The timeout waiting
56 for the client to send WINODW_UPDATE was incorrectly KeepAliveTimeout and not
57 Timeout as it should be. Fixes PR 63534. [Yann Ylavic, Stefan Eissing]
59 *) mod_ssl/mod_md: reversing dependency by letting mod_ssl offer hooks for
60 adding certificates and keys to a virtual host. An additional hook allows
61 answering special TLS connections as used in ACME challenges.
62 Adding 2 new hooks for init/get of OCSP stapling status information when
63 other modules want to provide those. Falls back to own implementation with
64 same behaviour as before.
67 *) mod_ssl: use OPENSSL_init_ssl() to initialise OpenSSL on versions 1.1+.
70 *) mod_proxy_http2: adding support for handling trailers in both directions. PR 63502.
73 *) mod_reqtimeout: Fix default rates missing (not applied) in 2.4.39.
74 PR 63325. [Yann Ylavic]
76 *) mod_ldap: Avoid potential crashes in util_ldap_cache_module_kill() or other
77 LDAP related functions during graceful restart of a busy server. PR63305.
78 [Martin Fúsek <mfusek newps.cz>]
80 *) mod_cache: Fix parsing of quoted Cache-Control token arguments.
81 PR 63288. [Yann Ylavic]
83 *) mod_md: Store permissions are enforced on file creation, enforcing restrictions in
84 spite of umask. Fixes <https://github.com/icing/mod_md/issues/117>. [Stefan Eissing]
86 *) mod_ssl: Correctly restore SSL verify state after TLSv1.3 PHA failure.
87 [Michael Kaufmann <mail michael-kaufmann.ch>]
89 *) Merge consecutive slashes in URL's. Opt-out with `MergeSlashes OFF`.
92 *) mod_proxy/ssl: Cleanup per-request SSL configuration anytime a backend
93 connection is recycled/reused to avoid a possible crash with some SSLProxy
94 configurations in <Location> or <Proxy> context. PR 63256. [Yann Ylavic]
96 *) mod_mime: Add `MimeOptions` directive to allow Content-Type or all metadata
97 detection to use only the last (right-most) file extension or to be
98 disabled per-dir. [Eric Covener]
100 *) MPMs unix: bind the bucket number of each child to its slot number, for a
101 more efficient per bucket maintenance. [Yann Ylavic]
103 *) http: Fix possible empty response with mod_ratelimit for HEAD requests.
104 PR 63192. [Yann Ylavic]
106 *) mod_cache_socache: Avoid reallocations and be safe with outgoing data
107 lifetime. [Yann Ylavic]
109 *) mod_reqtimeout: Allow to configure (TLS-)handshake timeouts.
110 PR 61310. [Yann Ylavic]
112 *) mod_auth_digest: Fix a race condition. Authentication with valid credentials could be
113 refused in case of concurrent accesses from different users.
114 PR 63124 [Simon Kappel <simon.kappel axis.com>]
116 *) mod_ssl: Don't unset FIPS mode on restart unless it's forced by
117 configuration (SSLFIPS on) and not active by default in OpenSSL.
118 PR 63136. [Yann Ylavic]
120 *) mod_ssl: give mod_md the chance to override certificate after ALPN protocol
121 negotiation. [Stefan Eissing]
123 *) mod_proxy_wstunnel: Fix websocket proxy over UDS.
124 PR 62932 <pavel dcmsys.com>
126 *) mod_negociation: LanguagePriority should be case-insensitive in order to
127 match AddLanguage behavior. PR 39730 [Christophe Jaillet]
129 *) mod_session: Always decode session attributes early. [Hank Ibell]
131 *) core: Incorrect values for environment variables are substituted when
132 multiple environment variables are specified in a directive. [Hank Ibell]
134 *) core: Split out the ability to parse wildcard files and directories
135 from the Include/IncludeOptional directives into a generic set of
136 functions ap_dir_nofnmatch() and ap_dir_fnmatch(). [Graham Leggett]
138 *) mod_ssl: Fix mod_authz provider for "require ssl" directive to check correctly
139 on HTTP/2 connections. Fixes PR 62654. [Stefan Eissing]
141 *) mod_ssl: clear *SSL errors before loading certificates and checking
142 afterwards. Otherwise errors are reported when other SSL using modules
143 are in play. Fixes PR 62880. [Michael Kaufmann]
145 *) core: Ensure that aborted connections are logged as such. PR 62823
146 [Arnaud Grandville <contact@grandville.net>]
148 *) mpm_event: Stop issuing AH00484 "server reached MaxRequestWorkers..." when
149 there are still idle threads available. When there are less idle threads than
150 MinSpareThreads, issue new one-time message AH10159. Matches worker MPM.
153 *) mod_proxy_scgi, mod_proxy_uwsgi: improve error handling when sending the
154 body of the response. [Jim Jagielski]
156 *) mod_session_cookie: avoid duplicate Set-Cookie header in the response.
157 [Emmanuel Dreyfus <manu@netbsd.org>, Luca Toscano]
159 *) mod_dav_fs: Set a default DAVLockDB within the state directory.
162 *) core: Add DefaultStateDir and layout-specific state directory
163 created at "make install". [Joe Orton]
165 *) ab: Add client certificate support. [Graham Leggett]
167 *) mod_proxy_hcheck: Fix issues with TCP health checks. PR 61499
168 [Dominik Stillhard <dominik.stillhard united-security-providers.ch>]
170 *) MPMs: Initialize all runtime/asynchronous objects on a dedicated pool and
171 before signals handling to avoid lifetime issues on restart or shutdown.
172 PR 62658. [Yann Ylavic]
174 *) core: Add StrictHostCheck to allow ucnonfigured hostnames to be
175 rejected. [Eric Covener]
177 *) mod_status: Cumulate CPU time of exited child processes in the
178 "cu" and "cs" values. Add CPU time of the parent process to the
182 *) mod_status: Add cumulated response duration time in milliseconds.
185 *) mod_status: Complete the data shown for async MPMs in "auto" mode.
186 Added number of processes, number of stopping processes and number
187 of busy and idle workers. [Rainer Jung]
189 *) mod_proxy: Improve the balancer member data shown in mod_status when
190 "ProxyStatus" is "On": add "busy" count and show byte counts in auto
191 mode always in units of kilobytes. [Rainer Jung]
193 *) mod_proxy: If ProxyPassReverse is used for reverse mapping of relative
194 redirects, subsequent ProxyPassReverse statements, whether they are
195 relative or absolute, may fail. PR 60408. [Peter Haworth <pmh1wheel gmail.com>]
197 *) mod_ratelimit: Don't interfere with "chunked" encoding, fixing regression
198 introduced in 2.4.34. PR 62568. [Yann Ylavic]
200 *) mod_proxy_http: forward 100-continue, and minimize race conditions when
201 reusing backend connections. PR 60330. [Yann Ylavic, Jean-Frederic Clere]
203 *) mod_proxy: Remove load order and link dependency between mod_lbmethod_*
204 modules and mod_proxy. PR 62557. [Ruediger Pluem, William Rowe]
206 *) mod_md: more robust handling of http-01 challenges and hands-off when module
207 should not be involved, e.g. challenge setup by another ACME client. [Stefan Eissing]
209 *) ru, zh-cn and zh-tw translations of errordocs have been added.
210 Contributed by Alexander Gaganashvili and CodeingBoy
212 *) mod_userdir: If several directories are given in a UserDir directive, only files
213 in the first existing one are checked. If the file is not found there, the
214 other possible directories are not checked. The doc clearly states that they
215 will be checked one by one, until a match is found or an external redirect is
219 *) mod_rewrite: Only create the global mutex used by "RewriteMap prg:" when
220 this type of map is present in the configuration. PR62311.
221 [Hank Ibell <hwibell gmail.com>]
223 *) mod_ldap: Abort on LDAP locking errors. [Eric Covener]
225 *) mod_ssl: Support loading certificates and private keys from the
226 PKCS#11 OpenSSL engine. [Anderson Sasaki <ansasaki redhat.com>,
229 *) http: LimitRequestBody applies to proxied requests. [Yann Ylavic]
231 *) mod_logio: Add LogIOTrackTTFU and %^FU logformat to log the time
232 difference between request start and last request body byte read (finished upload).
235 *) mod_ssl: add support for TLSv1.3 (tested with OpenSSL v1.1.1-pre4, other libs may
236 need more sugar). SSL(Proxy)CipherSuite now has an optional first parameter for the
237 protocol the ciphers are for.
238 Directive "SSLVerifyClient" now triggers certificate retrieval from the client (this
239 is not fully tested - but fails in similar fashion as in TLSv1.2 in my setups).
240 Verifying the client fails exactly the same for HTTP/2 connections for all SSL protocols,
241 as this would need to trigger the master connection thread - which we do not support
243 Renegotiation of ciphers is intentionally ignored for TLSv1.3 connections. "SSLCipherSuite"
244 does not allow to specify TLSv1.3 ciphers in a directory context (because it cannot work) and
245 TLSv1.2 or lower ciphers are not relevant, as cipher suites are completely separate.
246 This means there is a bit if a world split when simultaneously having TLSv1.2 and TLSv1.3
247 connections to the same server.
248 [Yann Ylavic, Stefan Eissing]
250 *) mod_ssl: proper checks for libressl 2.07/8 and its TLSv1_3 support, see PR 62236.
251 [Bernard Spil <brnrd@freebsd.org>]
253 *) mod_cgi: Add CGIScriptTimeout to make mod_cgi's timeout per-directory and
254 independent of the core Timeout directive. PR 62229.
255 [Hank Ibell <hwibell gmail.com>]
257 *) mod_ssl: heavily simplified SSLPolicy. No more user defines, no propxy policies,
258 just the basic "modern", "intermediate" and "old" as specified by Mozilla security.
261 *) mod_md: fixes error in renew window calculation that may lead to mod_md running
262 watchdog in a tight loop until actual renewal becomes necessary. [Stefan Eissing]
264 *) mod_md: /.well-known/acme-challenge requests that cannot be answered for hostnames
265 outside the configured MDs are free to be answered by other handlers. This allows
266 co-existance between mod_md and other ACME clients on the same server (implements PR62189).
267 [Stefan Eissing, Arkadiusz Miskiewicz <arekm@maven.pl>]
269 *) core: Create a conn_config_t structure to hold an extendable core config rather
270 than consuming the whole pointer with the connection socket. [Graham Leggett]
272 *) core: adding AP_DECLARE for ap_parse_vhost_addrs() and minor bumb mmn. Resolves
273 building mod_ssl on Windows. [Stefan Eissing, Gregg Smith]
275 *) core: adding defines to allow interworking with honggfuzz without
276 further patches. [Stefan Eissing, Robert Swiecki]
278 *) mod_headers: 'RequestHeader set|edit|edit_r Content-Type X' could
279 inadvertently modify the Content-Type _response_ header. Applies to
280 Content-Type only and likely to only affect static file responses.
283 *) mod_cgi: Improve AH01215 messages to make it more clear that the message is
284 the CGI scripts stderr output. PR 61980. [Hank Ibell <hwibell gmail.com>]
286 *) mod_headers: Allow 'Header unset Content-Type' to remove the Content-Type
287 header. PR 61983. [Hank Ibell <hwibell gmail.com>]
289 *) mod_md v1.1.8: new configuration directive "MDBaseServer on|off" to allow/inhibit
290 management of the base server domains outside VirtualHosts. By default, this is "off",
291 e.g. mod_md will not manage certificates or perform https: redirections on the
292 base server. [Stefan Eissing]
294 *) core: Add "AcceptErrorsNonFatal" to allow ECONNREFUSED, ECONNABORTED, and
295 ECONNRESET during the client accept() to not trigger graceful shutdown of
296 the child process. [Eric Covener]
299 - MDMustStaple was unable to create the necessary OpenSSL OBJ identifier on some platforms,
300 possibly because this fails if the OID is already configured in ```openssl.cnf```, see
301 [here](https://github.com/openssl/openssl/issues/2795).
302 - Two memory leaks in cert issuer and alt-names lookup eliminated by Yann Ylavic.
303 - Changing MDMustStaple triggers certificate renewal.
304 - More verbosity when *not* handing out certificates, e.g. mod_ssl asks, but mod_md has no
305 idea what it is talking about. Some people report misbehaviour here.
306 - Re-enabled support for md_get_credentials() function that was used in older mod_ssl
307 patch, so that people with old patched servers get a chance to upgrade.
308 [Stefan Eissing, Yann Ylavic]
310 *) mod_susbtitute: Allow expressions in the subtitution, prefixed with expr=
313 *) mod_md: fixed mem pool usage for auto-added server names. Added
314 error logging of exact ACME response when challenges failed.
317 *) mod_md: reverses most of v1.0.5 optimization of post_config init, so that
318 mod_ssl can ask for certiticates without crashing. [Stefan Eissing]
320 *) mod_proxy: allow SSLProxyCheckPeer* usage for all proxy modules.
321 PR 61857. [Yann Ylavic]
323 *) mod_proxy_html: fix handling of <meta http-equiv> elements.
326 *) mod_md: fixed backward compatibility to old <ManagedDomain configuration.
327 Add higher level WARNING log when initial request to ACME server fails, mentioning
328 some advice. [Stefan Eissing]
330 *) mod_md: name change in configuration directives. The old names are still working
331 in this version, so you can safely upgrade. They will give warnings in the log and
332 will disappear in the immediate future. ManagedDomain is now MDomain,
333 <ManagedDomain> is now <MDomainSet>. [Stefan Eissing]
335 *) mod_ssl: renamed section <SSLPolicy to <SSLPolicyDefine. Fixed behaviour
336 for new server config merge flag. Denying global, only once used directives
337 inside a SSLPolicyDefine. [Stefan Eissing]
339 *) mod_auth_basic: Be less tolerant when parsing the credencial. Only spaces
340 should be accepted after the authorization scheme. \t are also tolerated.
343 *) core: Support zone/scope in IPv6 link-local addresses in Listen and
344 VirtualHost directives (requires APR 1.7.x or later). PR 59396. [Joe Orton]
346 *) mod_md: v1.0.5, restricting post_config dry run to be more silent and performing
347 only necessary work for mod_ssl to be also happy with the configuration.
350 *) mod_md: v1.0.4, removed the 'a2md' utility command from build. Only used in github
351 testing. Avoid problems with our build system that had problems after the latest
352 changes to make a clean initial build. Remove the windows a2md.dsp therefore also.
355 *) mod_ssl: Fail with 403 if the username for FakeBasicAuth mode
356 includes a colon character. PR 52644. [Joe Orton]
358 *) mod_md: v1.0.3, fixed various bugs in persisting job properties, so that status is
359 persisted accross child process changes and staging is reset on reloads. Changed
360 MDCertificateAgreement url checks. As long as the CA reports that the account has
361 an agreement, no further checking is done. Existing accounts need no changes when
362 a new agreement comes out. [Stefan Eissing]
364 *) mod_watchdog: Correct some log messages. [Rainer Jung]
366 *) mod_noloris: complete build setup. [Rainer Jung]
368 *) mod_md: fix static compilation. [Rainer Jung]
370 *) mod_md: fix compilation of helper binary a2md. [Rainer Jung]
372 *) core: fix pcre feature detection in configure when using pcre2. [Rainer Jung]
374 Changes with Apache 2.5.0-alpha
376 *) mod_md: v1.0.1, ServerName/Alias names from pure-http: virtual hosts are no longer
377 auto-added to a Managed Domain. Error counts of jobs are presisted. When the server
378 restarts (gracefully) any errored staging areas are purged to reset the signup/renewal
379 process. [Stefan Eissing]
381 *) mod_md: v1.0.0, new config directive 'MDNotifyCmd' to hook in a program when Managed
382 Domains have obtained/renewed their certificates successfully. [Stefan Eissing]
384 *) mod_md: v0.9.9, fix for applying challenge type based on available ports. [Stefan Eissing]
387 - Use of the new module flag
388 - Removed obsolete function from interface to mod_ssl.
389 - Fallback certificates has version set and no longer claims to be a CA. (re issue #32)
390 - MDRequireHttps now happens before any Redirect.
393 *) mod_ssl: unshare SSLSrvConfigRec instances between base server and virtual hosts. This avoids
394 overwrites of later initializattions (vhost_id), selective disables by "SSLEngine addr-list"
395 and certificate/key pickup from mod_md. [Stefan Eissing]
397 *) mod_md: v0.9.6: a "MDRequireHttps permament" configured domain automatically sends out
398 HSTS (rfc 6797) headers in https: responses. [Stefan Eissing]
400 *) mod_ssl: adding ssl_policies.h[.in] for policy cipher/protocol definitions. Use
401 update_policies.py to update manually from Mozilla JSON definitions at
402 https://statics.tls.security.mozilla.org/server-side-tls-conf.json
406 - New directive (srly: what do you expect at this point?) "MDMustStaple on|off" to control if
407 new certificates are requested with the OCSP Must Staple extension.
408 - Known limitation: when the server is configured to ditch and restart child processes, for example
409 after a certain number of connections/requests, the mod_md watchdog instance might migrate
410 to a new child process. Since not all its state is persisted, some messsages might appear a
411 second time in the logs.
412 - Adding checks when 'MDRequireHttps' is used. It is considered an error when 'MDPortMap 443:-'
413 is used - which negates that a https: port exists. Also, a warning is logged if no
414 VirtualHost can be found for a Managed Domain that has port 443 (or the mapped one) in
416 - New directive 'MDRequireHttps' for redirecting http: traffic to a Managed Domain, permanently
418 - Fix for using a fallback certificate on initial signup of a Managed Domain. Requires also
419 a changed mod_ssl patch (v5) to take effect.
420 - compatibility with libressl
423 *) mod_md: v0.9.2: new directive 'MDHttpProxy' to define a proxy for outgoing connection,
424 some minor bugfixes, twiddle the build system to avoid non-pic code generation.
428 - various fixes in MDRenewWindow handling when specifying percent. Serialization changed. If
429 someone already used percent configurations, it is advised to change these to a new value,
430 reload and change back to the wanted ones.
431 - various fixes in handling of MDPrivateKeys when specifying 2048 bits (the default) explicitly.
432 - mod_md version removed from top level md_store.json file. The store has its own format version
433 to facilitate upgrades.
437 Certificate provisioning from Let's Encrypt (and other ACME CAs) for mod_ssl virtual hosts.
440 *) mod_ssl: add SSLPolicy (define/use) and SSLProxyPolicy directives plus documentation. Add
441 core definitions for policies 'modern', 'intermediate' and 'old', as defined by Mozilla
442 in <https://wiki.mozilla.org/Security/Server_Side_TLS>. [Stefan Eissing]
444 *) mod_md: new module for managing domains across VirtualHosts with ACME protocol
445 implementation for automated certificate signup and renewal. Default CA is
446 the test area of Let's Encrypt right now, so certificates root will not be valid.
447 Will be switched to the real service endpoint rather soon. If you need it now,
448 configure 'MDCertificateAuthority https://acme-v01.api.letsencrypt.org/directory'.
451 *) mod_rewrite: Add 'RewriteOptions LongURLOptimization' to free memory
452 from each set of unmatched rewrite conditions.
455 *) Allow the argument to <IfFile>, <IfDefine>, <IfSection>, <IfDirective>,
456 and <IfModule> to be quoted. This is primarily for the benefit of
457 <IfFile>. [Eric Covener]
459 *) Introduce request taint checking framework to prevent privilege
460 hijacking through .htaccess. [Nick Kew]
462 *) Add <IfDirective> and <IfSection> directives. [Joe Orton]
464 *) When using mod_status with the Event MPM, report the number of requests
465 associated with an active connection in the "ACC" field. Previously
466 zero was always reported with this MPM. PR60647. [Eric Covener]
468 *) mod_proxy_wstunnel: Reliably run before mod_proxy_http.
471 *) http: Allow unknown response status' lines returned in the form of
472 "HTTP/x.x xxx Status xxx". [Yann Ylavic]
474 *) core: Add <IfFile> configuration section to allow any file on disk to be
475 used as a conditional. [Edward Lu, Eric Covener]
477 *) mod_crypto: Add the all purpose crypto filters with support for HLS.
480 *) core: Drop an invalid Last-Modified header value coming
481 from a FCGI/CGI script instead of replacing it with Unix epoch.
482 Warn the users about Last-Modified header value replacements
483 and violations of the RFC.
484 [Yann Ylavic, Luca Toscano, William Rowe, Jacob Champion]
486 *) mod_dav: Allow other modules to become providers and add ACLs
488 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
490 *) mod_dav: Add dav_begin_multistatus, dav_send_one_response,
491 dav_finish_multistatus, dav_send_multistatus, dav_handle_err,
492 dav_failed_proppatch, dav_success_proppatch to mod_dav.h.
493 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
495 *) core: explicitly exclude 'h2' from protocols announced via an Upgrade:
496 header as commanded by http-wg. [Stefan Eissing]
498 *) mod_proxy_ajp: Add "secret" parameter to proxy workers to implement legacy
499 AJP13 authentication. PR 53098. [Dmitry A. Bakshaev <dab1818 gmail com>]
501 *) mpm: Generalise the ap_mpm_register_socket functions to accept pipes
502 or sockets. [Graham Leggett]
504 *) core: Extend support for setting aside data from the network input filter
505 to any connection or request input filter. [Graham Leggett]
507 *) core: Split ap_create_request() from ap_read_request(). [Graham Leggett]
509 *) mod_auth_digest: Fix compatibility with expression-based Authname. PR59039.
512 *) mpm: Add a complete_connection hook that confirms whether an MPM is allowed
513 to leave the WRITE_COMPLETION phase. Move filter code out of the MPMs.
516 *) mod_cache: Consider Cache-Control: s-maxage in expiration
517 calculations. [Eric Covener]
519 *) mod_cache: Allow caching of responses with an Expires header
520 in the past that also has Cache-Control: max-age or s-maxage.
521 PR55156. [Eric Covener]
523 *) mod_session: Introduce SessionExpiryUpdateInterval which allows to
524 configure the session/cookie expiry's update interval. PR 57300.
525 [Paul Spangler <paul.spangler ni.com>]
527 *) core: Extend support for asynchronous write completion from the
528 network filter to any connection or request filter. [Graham Leggett]
530 *) mod_auth_digest: remove AuthDigestEnableQueryStringHack which is no
531 more documented since dec 2012 (r1415960). [Christophe Jaillet]
533 *) mod_charset_lite: On EBCDIC platforms, make sure mod_charset_lite runs
534 after other resource-level filters. [Eric Covener]
536 *) http: Don't remove the Content-Length of zero from a HEAD response if
537 it comes from an origin server, module or script. [Yann Ylavic]
539 *) http: Add support for RFC2324/RFC7168. [Graham Leggett]
541 *) mod_authn_core: Add expression support to AuthName and AuthType.
544 *) suexec: Filter out the HTTP_PROXY environment variable because it is
545 treated as alias for http_proxy by some programs. [Stefan Fritsch]
547 *) mod_proxy_http: Don't establish or reuse a backend connection before pre-
548 fetching the request body, so to minimize the delay between it is supposed
549 to be alive and the first bytes sent: this is a best effort to prevent the
550 backend from closing because of idle or keepalive timeout in the meantime.
551 Also, handle a new "proxy-flushall" environment variable which allows to
552 flush any forwarded body data immediately. PR 56541+37920. [Yann Ylavic]
554 *) core: Define and UnDefine are no longer permitted in
555 directory context. Previously they would always be evaulated

611 *) Add the ldap-search option to mod_authnz_ldap, allowing authorization
612 to be based on arbitrary expressions that do not include the username.
615 *) Add the ldap function to the expression API, allowing LDAP filters and
616 distinguished names based on expressions to be escaped correctly to
617 guard against LDAP injection. [Graham Leggett]
619 *) Add module mod_ssl_ct, which provides an implementation of Certificate
620 Transparency (RFC 6962) for httpd. [Jeff Trawick]
622 *) mod_proxy_wstunnel: Avoid sending error responses down an upgraded

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

686 *) mod_syslog: New module implementing syslog ap_error_log provider.
687 Previously, this code was part of core, now it's in separate module.
690 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
691 syslog support from core to new mod_syslog. [Jan Kaluza]
693 *) mod_status, mod_echo: Fix the display of client addresses.
694 They were truncated to 31 characters which is not enough for IPv6 addresses.
695 This is done by deprecating the use of the 'client' field and using
696 the new 'client64' field in worker_score.

709 been configured with -D Z_PREFIX, which redefines the token "deflate".
712 *) mod_auth_digest: Use the secret when generating nonces in all cases and
713 not only when AuthName is used in .htaccess files (this change may cause
714 problems if used with round robin load balancers). Don't regenerate the
715 secret on graceful restarts. PR 54637 [Stefan Fritsch]
717 *) core: Stop the HTTP_IN filter from attempting to write error buckets
718 to the output filters, which is bogus in the proxy case. Create a
