2 Changes with Apache 2.5.1
4 *) mod_status: Cumulate CPU time of exited child processes in the
5 "cu" and "cs" values. Add CPU time of the parent process to the
9 *) mod_status: Add cumulated response duration time in milliseconds.
12 *) mod_status: Complete the data shown for async MPMs in "auto" mode.
13 Added number of processes, number of stopping processes and number
14 of busy and idle workers. [Rainer Jung]
16 *) mod_proxy: Improve the balancer member data shown in mod_status when
17 "ProxyStatus" is "On": add "busy" count and show byte counts in auto
18 mode always in units of kilobytes. [Rainer Jung]
20 *) mod_proxy: If ProxyPassReverse is used for reverse mapping of relative
21 redirects, subsequent ProxyPassReverse statements, whether they are
22 relative or absolute, may fail. PR 60408. [Peter Haworth <pmh1wheel gmail.com>]
24 *) mod_ratelimit: Don't interfere with "chunked" encoding, fixing regression
25 introduced in 2.4.34. PR 62568. [Yann Ylavic]
27 *) http: Enforce consistently no response body with both 204 and 304
28 statuses. [Yann Ylavic]
30 *) mod_proxy_http: forward 100-continue, and minimize race conditions when
31 reusing backend connections. PR 60330. [Yann Ylavic, Jean-Frederic Clere]
33 *) mod_proxy: Remove load order and link dependency between mod_lbmethod_*
34 modules and mod_proxy. PR 62557. [Ruediger Pluem, William Rowe]
36 *) mod_md: more robust handling of http-01 challenges and hands-off when module
37 should not be involved, e.g. challenge setup by another ACME client. [Stefan Eissing]
39 *) ru, zh-cn and zh-tw translations of errordocs have been added.
40 Contributed by Alexander Gaganashvili and CodeingBoy
42 *) mod_authz_core: If several parameters are used in a AuthzProviderAlias
43 directive, if these parameters are not enclosed in quotation mark, only
44 the first one is handled. The other ones are silently ignored.
45 Add a message to warn about such a spurious configuration.
46 PR 62469 [Hank Ibell <hwibell gmail.com>, Christophe Jaillet]
48 *) mod_proxy_wstunnel: Add default schema ports for 'ws' and 'wss'.
49 PR 62480. [Lubos Uhliarik <luhliari redhat.com>}
51 *) http: Fix small memory leak per request when handling persistent
52 connections. [Ruediger Pluem, Joe Orton]
54 *) mod_remoteip: Fix RemoteIP{Trusted,Internal}ProxyList loading broken by 2.4.30.
55 PR 62220. [Chritophe Jaillet, Yann Ylavic]
57 *) mod_userdir: If several directories are given in a UserDir directive, only files
58 in the first existing one are checked. If the file is not found there, the
59 other possible directories are not checked. The doc clearly states that they
60 will be checked one by one, until a match is found or an external redirect is
64 *) mod_proxy: Fix a corner case where the ProxyPassReverseCookieDomain or
65 ProxyPassReverseCookiePath directive could fail to update correctly
66 'domain=' or 'path=' in the 'Set-Cookie' header. PR 61560.
69 *) mod_slotmem_shm: Add generation number to shm filename to fix races
70 with graceful restarts. PRs 62044 and 62308. [Jim Jagielski, Yann Ylavic]
72 *) mod_rewrite: Only create the global mutex used by "RewriteMap prg:" when
73 this type of map is present in the configuration. PR62311.
74 [Hank Ibell <hwibell gmail.com>]
76 *) mod_ldap: Abort on LDAP locking errors. [Eric Covener]
78 *) mod_ssl: Support loading certificates and private keys from the
79 PKCS#11 OpenSSL engine. [Anderson Sasaki <ansasaki redhat.com>,
82 *) mod_proxy_html: Fix variable interpolation and memory allocation failure
83 in ProxyHTMLURLMap. [Ewald Dieterich <ewald mailbox.org>]
85 *) core: In ONE_PROCESS/debug mode, cleanup everything when exiting.
88 *) mod_http2: adding an abort function to slave connections' pools, so out-of-memory
89 events lead to a control process abort, as on HTTP/1.x connections. [Stefan Eissing]
91 *) mod_http2: adding regular memory cleanup when transferring large response bodies. This
92 reduces memory footprint and avoids memory exhaustion when transferring large files
93 on 32-bit architectures. Fixes PR 62325. [Stefan Eissing]
95 *) http: LimitRequestBody applies to proxied requests. [Yann Ylavic]
97 *) mod_logio: Add LogIOTrackTTFU and %^FU logformat to log the time
98 difference between request start and last request body byte read (finished upload).
101 *) mod_ssl: add support for TLSv1.3 (tested with OpenSSL v1.1.1-pre4, other libs may
102 need more sugar). SSL(Proxy)CipherSuite now has an optional first parameter for the
103 protocol the ciphers are for.
104 Directive "SSLVerifyClient" now triggers certificate retrieval from the client (this
105 is not fully tested - but fails in similar fashion as in TLSv1.2 in my setups).
106 Verifying the client fails exactly the same for HTTP/2 connections for all SSL protocols,
107 as this would need to trigger the master connection thread - which we do not support
109 Renegotiation of ciphers is intentionally ignored for TLSv1.3 connections. "SSLCipherSuite"
110 does not allow to specify TLSv1.3 ciphers in a directory context (because it cannot work) and
111 TLSv1.2 or lower ciphers are not relevant, as cipher suites are completely separate.
112 This means there is a bit if a world split when simultaneously having TLSv1.2 and TLSv1.3
113 connections to the same server.
116 *) mod_ssl: proper checks for libressl 2.07/8 and its TLSv1_3 support, see PR 62236.
117 [Bernard Spil <brnrd@freebsd.org>]
119 *) mod_http2: on level trace2, log any unsuccessful HTTP/2 direct connection upgrade
120 with base64 encoding to unify its appearance in possible bug reports. [Stefan Eissing]
122 *) mod_cgi: Add CGIScriptTimeout to make mod_cgi's timeout per-directory and
123 independent of the core Timeout directive. PR 62229.
124 [Hank Ibell <hwibell gmail.com>]
126 *) mod_ssl: heavily simplified SSLPolicy. No more user defines, no propxy policies,
127 just the basic "modern", "intermediate" and "old" as specified by Mozilla security.
130 *) mod_md: fixes error in renew window calculation that may lead to mod_md running
131 watchdog in a tight loop until actual renewal becomes necessary. [Stefan Eissing]
133 *) mod_md: /.well-known/acme-challenge requests that cannot be answered for hostnames
134 outside the configured MDs are free to be answered by other handlers. This allows
135 co-existance between mod_md and other ACME clients on the same server (implements PR62189).
136 [Stefan Eissing, Arkadiusz Miskiewicz <arekm@maven.pl>]
138 *) core: Create a conn_config_t structure to hold an extendable core config rather
139 than consuming the whole pointer with the connection socket. [Graham Leggett]
141 *) core: adding AP_DECLARE for ap_parse_vhost_addrs() and minor bumb mmn. Resolves
142 building mod_ssl on Windows. [Stefan Eissing, Gregg Smith]
144 *) mod_http2: discourage gzip/brotli content encoding on http2-status responses as
145 they are inserted into the reponse when filters are already done. [Stefan Eissing]
147 *) core: adding defines to allow interworking with honggfuzz without
148 further patches. [Stefan Eissing, Robert Swiecki]
150 *) mod_headers: 'RequestHeader set|edit|edit_r Content-Type X' could
151 inadvertently modify the Content-Type _response_ header. Applies to
152 Content-Type only and likely to only affect static file responses.
155 *) mod_cgi: Improve AH01215 messages to make it more clear that the message is
156 the CGI scripts stderr output. PR 61980. [Hank Ibell <hwibell gmail.com>]
158 *) mod_headers: Allow 'Header unset Content-Type' to remove the Content-Type
159 header. PR 61983. [Hank Ibell <hwibell gmail.com>]
161 *) mod_md v1.1.8: new configuration directive "MDBaseServer on|off" to allow/inhibit
162 management of the base server domains outside VirtualHosts. By default, this is "off",
163 e.g. mod_md will not manage certificates or perform https: redirections on the
164 base server. [Stefan Eissing]
166 *) core: Add "AcceptErrorsNonFatal" to allow ECONNREFUSED, ECONNABORTED, and
167 ECONNRESET during the client accept() to not trigger graceful shutdown of
168 the child process. [Eric Covener]
171 - MDMustStaple was unable to create the necessary OpenSSL OBJ identifier on some platforms,
172 possibly because this fails if the OID is already configured in ```openssl.cnf```, see
173 [here](https://github.com/openssl/openssl/issues/2795).
174 - Two memory leaks in cert issuer and alt-names lookup eliminated by Yann Ylavic.
175 - Changing MDMustStaple triggers certificate renewal.
176 - More verbosity when *not* handing out certificates, e.g. mod_ssl asks, but mod_md has no
177 idea what it is talking about. Some people report misbehaviour here.
178 - Re-enabled support for md_get_credentials() function that was used in older mod_ssl
179 patch, so that people with old patched servers get a chance to upgrade.
180 [Stefan Eissing, Yann Ylavic]
182 *) mod_susbtitute: Allow expressions in the subtitution, prefixed with expr=
185 *) mod_md: fixed mem pool usage for auto-added server names. Added
186 error logging of exact ACME response when challenges failed.
189 *) mod_md: reverses most of v1.0.5 optimization of post_config init, so that
190 mod_ssl can ask for certiticates without crashing. [Stefan Eissing]
192 *) mod_proxy: allow SSLProxyCheckPeer* usage for all proxy modules.
193 PR 61857. [Yann Ylavic]
195 *) mod_proxy_html: fix handling of <meta http-equiv> elements.
198 *) mod_md: fixed backward compatibility to old <ManagedDomain configuration.
199 Add higher level WARNING log when initial request to ACME server fails, mentioning
200 some advice. [Stefan Eissing]
202 *) mod_md: name change in configuration directives. The old names are still working
203 in this version, so you can safely upgrade. They will give warnings in the log and
204 will disappear in the immediate future. ManagedDomain is now MDomain,
205 <ManagedDomain> is now <MDomainSet>. [Stefan Eissing]
207 *) mod_ssl: renamed section <SSLPolicy to <SSLPolicyDefine. Fixed behaviour
208 for new server config merge flag. Denying global, only once used directives
209 inside a SSLPolicyDefine. [Stefan Eissing]
211 *) mod_auth_basic: Be less tolerant when parsing the credencial. Only spaces
212 should be accepted after the authorization scheme. \t are also tolerated.
215 *) mod_http2: fixed unfair scheduling when number of active connections
216 exceeded the scheduling fifo capacity. [Stefan Eissing]
218 *) core: Support zone/scope in IPv6 link-local addresses in Listen and
219 VirtualHost directives (requires APR 1.7.x or later). PR 59396. [Joe Orton]
221 *) mod_md: v1.0.5, restricting post_config dry run to be more silent and performing
222 only necessary work for mod_ssl to be also happy with the configuration.
225 *) mod_md: v1.0.4, removed the 'a2md' utility command from build. Only used in github
226 testing. Avoid problems with our build system that had problems after the latest
227 changes to make a clean initial build. Remove the windows a2md.dsp therefore also.
230 *) mod_ssl: Fail with 403 if the username for FakeBasicAuth mode
231 includes a colon character. PR 52644. [Joe Orton]
233 *) mod_md: v1.0.3, fixed various bugs in persisting job properties, so that status is
234 persisted accross child process changes and staging is reset on reloads. Changed
235 MDCertificateAgreement url checks. As long as the CA reports that the account has
236 an agreement, no further checking is done. Existing accounts need no changes when
237 a new agreement comes out. [Stefan Eissing]
239 *) mod_watchdog: Correct some log messages. [Rainer Jung]
241 *) mod_noloris: complete build setup. [Rainer Jung]
243 *) mod_md: fix static compilation. [Rainer Jung]
245 *) mod_md: fix compilation of helper binary a2md. [Rainer Jung]
247 *) core: fix pcre feature detection in configure when using pcre2. [Rainer Jung]
249 Changes with Apache 2.5.0-alpha
251 *) mod_md: v1.0.1, ServerName/Alias names from pure-http: virtual hosts are no longer
252 auto-added to a Managed Domain. Error counts of jobs are presisted. When the server
253 restarts (gracefully) any errored staging areas are purged to reset the signup/renewal
254 process. [Stefan Eissing]
256 *) mod_md: v1.0.0, new config directive 'MDNotifyCmd' to hook in a program when Managed
257 Domains have obtained/renewed their certificates successfully. [Stefan Eissing]
259 *) mod_md: v0.9.9, fix for applying challenge type based on available ports. [Stefan Eissing]
262 - Use of the new module flag
263 - Removed obsolete function from interface to mod_ssl.
264 - Fallback certificates has version set and no longer claims to be a CA. (re issue #32)
265 - MDRequireHttps now happens before any Redirect.
268 *) mod_ssl: unshare SSLSrvConfigRec instances between base server and virtual hosts. This avoids
269 overwrites of later initializattions (vhost_id), selective disables by "SSLEngine addr-list"
270 and certificate/key pickup from mod_md. [Stefan Eissing]
272 *) mod_md: v0.9.6: a "MDRequireHttps permament" configured domain automatically sends out
273 HSTS (rfc 6797) headers in https: responses. [Stefan Eissing]
275 *) mod_ssl: adding ssl_policies.h[.in] for policy cipher/protocol definitions. Use
276 update_policies.py to update manually from Mozilla JSON definitions at
277 https://statics.tls.security.mozilla.org/server-side-tls-conf.json
281 - New directive (srly: what do you expect at this point?) "MDMustStaple on|off" to control if
282 new certificates are requested with the OCSP Must Staple extension.
283 - Known limitation: when the server is configured to ditch and restart child processes, for example
284 after a certain number of connections/requests, the mod_md watchdog instance might migrate
285 to a new child process. Since not all its state is persisted, some messsages might appear a
286 second time in the logs.
287 - Adding checks when 'MDRequireHttps' is used. It is considered an error when 'MDPortMap 443:-'
288 is used - which negates that a https: port exists. Also, a warning is logged if no
289 VirtualHost can be found for a Managed Domain that has port 443 (or the mapped one) in
291 - New directive 'MDRequireHttps' for redirecting http: traffic to a Managed Domain, permanently
293 - Fix for using a fallback certificate on initial signup of a Managed Domain. Requires also
294 a changed mod_ssl patch (v5) to take effect.
295 - compatibility with libressl
298 *) mod_md: v0.9.2: new directive 'MDHttpProxy' to define a proxy for outgoing connection,
299 some minor bugfixes, twiddle the build system to avoid non-pic code generation.
303 - various fixes in MDRenewWindow handling when specifying percent. Serialization changed. If
304 someone already used percent configurations, it is advised to change these to a new value,
305 reload and change back to the wanted ones.
306 - various fixes in handling of MDPrivateKeys when specifying 2048 bits (the default) explicitly.
307 - mod_md version removed from top level md_store.json file. The store has its own format version
308 to facilitate upgrades.
312 Certificate provisioning from Let's Encrypt (and other ACME CAs) for mod_ssl virtual hosts.
315 *) mod_ssl: add SSLPolicy (define/use) and SSLProxyPolicy directives plus documentation. Add
316 core definitions for policies 'modern', 'intermediate' and 'old', as defined by Mozilla
317 in <https://wiki.mozilla.org/Security/Server_Side_TLS>. [Stefan Eissing]
319 *) mod_md: new module for managing domains across VirtualHosts with ACME protocol
320 implementation for automated certificate signup and renewal. Default CA is
321 the test area of Let's Encrypt right now, so certificates root will not be valid.
322 Will be switched to the real service endpoint rather soon. If you need it now,
323 configure 'MDCertificateAuthority https://acme-v01.api.letsencrypt.org/directory'.
326 *) mod_rewrite: Add 'RewriteOptions LongURLOptimization' to free memory
327 from each set of unmatched rewrite conditions.
330 *) Allow the argument to <IfFile>, <IfDefine>, <IfSection>, <IfDirective>,
331 and <IfModule> to be quoted. This is primarily for the benefit of
332 <IfFile>. [Eric Covener]
334 *) Introduce request taint checking framework to prevent privilege
335 hijacking through .htaccess. [Nick Kew]
337 *) Add <IfDirective> and <IfSection> directives. [Joe Orton]
339 *) When using mod_status with the Event MPM, report the number of requests
340 associated with an active connection in the "ACC" field. Previously
341 zero was always reported with this MPM. PR60647. [Eric Covener]
343 *) mod_remoteip: When overriding the useragent address from X-Forwarded-For,
344 zero out what had been initialized as the connection-level port. PR59931.
345 [Hank Ibell <hwibell gmail.com>]
347 *) mod_proxy_wstunnel: Reliably run before mod_proxy_http.
350 *) http: Allow unknown response status' lines returned in the form of
351 "HTTP/x.x xxx Status xxx". [Yann Ylavic]
353 *) core: Add <IfFile> configuration section to allow any file on disk to be
354 used as a conditional. [Edward Lu, Eric Covener]
356 *) mod_crypto: Add the all purpose crypto filters with support for HLS.
359 *) core: Drop an invalid Last-Modified header value coming
360 from a FCGI/CGI script instead of replacing it with Unix epoch.
361 Warn the users about Last-Modified header value replacements
362 and violations of the RFC.
363 [Yann Ylavic, Luca Toscano, William Rowe, Jacob Champion]
365 *) mod_dav: Allow other modules to become providers and add ACLs
367 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
369 *) mod_dav: Add dav_begin_multistatus, dav_send_one_response,
370 dav_finish_multistatus, dav_send_multistatus, dav_handle_err,
371 dav_failed_proppatch, dav_success_proppatch to mod_dav.h.
372 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
374 *) core: explicitly exclude 'h2' from protocols announced via an Upgrade:
375 header as commanded by http-wg. [Stefan Eissing]
377 *) mod_proxy_ajp: Add "secret" parameter to proxy workers to implement legacy
378 AJP13 authentication. PR 53098. [Dmitry A. Bakshaev <dab1818 gmail com>]
380 *) mpm: Generalise the ap_mpm_register_socket functions to accept pipes
381 or sockets. [Graham Leggett]
383 *) core: Extend support for setting aside data from the network input filter
384 to any connection or request input filter. [Graham Leggett]
386 *) core: Split ap_create_request() from ap_read_request(). [Graham Leggett]
388 *) mod_auth_digest: Fix compatibility with expression-based Authname. PR59039.
391 *) mpm: Add a complete_connection hook that confirms whether an MPM is allowed
392 to leave the WRITE_COMPLETION phase. Move filter code out of the MPMs.
395 *) mod_cache: Consider Cache-Control: s-maxage in expiration
396 calculations. [Eric Covener]
398 *) mod_cache: Allow caching of responses with an Expires header
399 in the past that also has Cache-Control: max-age or s-maxage.
400 PR55156. [Eric Covener]
402 *) mod_session: Introduce SessionExpiryUpdateInterval which allows to
403 configure the session/cookie expiry's update interval. PR 57300.
404 [Paul Spangler <paul.spangler ni.com>]
406 *) core: Extend support for asynchronous write completion from the
407 network filter to any connection or request filter. [Graham Leggett]
409 *) mod_auth_digest: remove AuthDigestEnableQueryStringHack which is no
410 more documented since dec 2012 (r1415960). [Christophe Jaillet]
412 *) mod_charset_lite: On EBCDIC platforms, make sure mod_charset_lite runs
413 after other resource-level filters. [Eric Covener]
415 *) http: Don't remove the Content-Length of zero from a HEAD response if
416 it comes from an origin server, module or script. [Yann Ylavic]
418 *) http: Add support for RFC2324/RFC7168. [Graham Leggett]
420 *) mod_authn_core: Add expression support to AuthName and AuthType.
423 *) suexec: Filter out the HTTP_PROXY environment variable because it is
424 treated as alias for http_proxy by some programs. [Stefan Fritsch]
426 *) mod_proxy_http: Don't establish or reuse a backend connection before pre-
427 fetching the request body, so to minimize the delay between it is supposed
428 to be alive and the first bytes sent: this is a best effort to prevent the
429 backend from closing because of idle or keepalive timeout in the meantime.
430 Also, handle a new "proxy-flushall" environment variable which allows to
431 flush any forwarded body data immediately. PR 56541+37920. [Yann Ylavic]
433 *) core: Define and UnDefine are no longer permitted in
434 directory context. Previously they would always be evaulated
435 as the configuration was read without regard for the directory
436 context. [Eric Covener]
438 *) config: For directives that do not expect any arguments, enforce
439 that none are specified in the configuration file.
440 [Joachim Zobel <jzobel heute-morgen.de>, Eric Covener]
442 *) mod_rewrite: Improve 'bad flag delimeters' startup error by showing
443 how the input was tokenized. PR 56528. [Edward Lu <Chaosed0 gmail.com>]
445 *) mod_proxy: Don't put non balancer-member workers in error state by
446 default for connection or 500/503 errors, and honor status=+I for
447 any error. PR 48388. [Yann Ylavic]
449 *) ap_expr: Add filemod function for checking file modification dates
452 *) mod_authnz_ldap: Resolve crashes with LDAP authz and non-LDAP authn since
453 r1608202. [Eric Covener]
455 *) apreq: Content-Length header should be always interpreted as a decimal.
456 Leading 0 could be erroneously considered as an octal value. PR 56598.
457 [Chris Card <ctcard hotmail com>]
459 *) mod_proxy: Now allow for 191 character worker names, with non-fatal
460 errors if name is truncated. PR53218. [Jim Jagielski]
462 *) mod_ssl: Add optional function "ssl_get_tls_cb" to allow support
463 for channel bindings. [Simo Sorce <simo redhat.com>]
465 *) mod_proxy_wstunnel: Concurrent websockets messages could be
466 lost or delayed with ProxyWebsocketAsync enabled.
467 [Edward Lu <Chaosed0 gmail.com>]
469 *) core, mod_info: Add compiled and loaded PCRE versions to version
470 number display. [Rainer Jung]
472 *) mod_authnz_ldap: Return LDAP connections to the pool before the handler
473 is run, instead of waiting until the end of the request. [Eric Covener]
475 *) mod_proxy_html: support automatic detection of doctype and processing
476 of FPIs. PR56285 [Micha Lenk <micha lenk info>, Nick Kew]
478 *) core: Add ap_mpm_resume_suspended() API to allow a suspended connection
480 [Artem <artemciy gmail.com>, Edward Lu <Chaosed0 gmail.com>]
482 *) core: Add ap_mpm_register_socket_callback_timeout() API. [Eric Covener]
484 *) mod_proxy_wstunnel: Honor ProxyWebsocketIdleTimeout in asynchronous
485 processing mode. [Eric Covener]
487 *) mod_authnz_ldap: Fail explicitly when the filter is too long. Remove
488 unnecessary apr_pstrdup() and strlen(). [Graham Leggett]
490 *) Add the ldap-search option to mod_authnz_ldap, allowing authorization
491 to be based on arbitrary expressions that do not include the username.
494 *) Add the ldap function to the expression API, allowing LDAP filters and
495 distinguished names based on expressions to be escaped correctly to
496 guard against LDAP injection. [Graham Leggett]
498 *) Add module mod_ssl_ct, which provides an implementation of Certificate
499 Transparency (RFC 6962) for httpd. [Jeff Trawick]
501 *) mod_proxy_wstunnel: Avoid sending error responses down an upgraded
502 websockets connection as it is being close down. [Eric Covener]
504 *) mod_proxy_wstunnel: Allow the administrator to cap the amount
505 of time a synchronous websockets connection stays idle with
506 ProxyWebsocketIdleTimeout. [Eric Covener]
508 *) mod_proxy_wstunnel: Change to opt-in for asynchronous support, adding
509 directives ProxyWebsocketAsync and ProxyWebsocketAsyncDelay.
512 *) mod_proxy_wstunnel: Stop leaking websockets backend connections under
513 event MPM (trunk-only). [Eric Covener]
515 *) mod_proxy_http: Add detach_backend hook (potentially usable
516 in other proxy scheme handlers). [Jeff Trawick]
518 *) mod_deflate: Add DeflateAlterETag to control how the ETag
519 is modified. The 'NoChange' parameter mimics 2.2.x behavior.
520 PR 45023, PR 39727. [Eric Covener]
522 *) mod_dir: Default to 2.2-like behavior and skip execution when method is
523 neither GET nor POST, such as for DAV requests. PR 54914. [Chris Darroch]
525 *) mod_rewrite: Rename the handler that does per-directory internal
526 redirects to "rewrite-redirect-handler" from "redirect-handler" so
527 it is less ambiguous and less likely to be reused. [Eric Covener]
529 *) mod_rewrite: Protect against looping with the [N] flag by enforcing a
530 default limit of 10000 iterations, and allowing each rule to change its
531 limit. [Eric Covener]
533 *) mod_ssl: Fix config merging of SSLOCSPEnable and SSLOCSPOverrideResponder.
536 *) Add HttpContentLengthHeadZero and HttpExpectStrict directives.
537 [Yehuda Sadeh <yehuda inktank com>, Justin Erenkrantz]
539 *) mod_ssl: Add -t -DDUMP_CA_CERTS option which dumps the filenames of all
540 configured SSL CA certificates to stdout the same way as DUMP_CERTS does.
543 *) mod_ssl: Don't flush when an EOS is received. Prepares mod_ssl
544 to support write completion. [Graham Leggett]
546 *) core: Add parse_errorlog_arg callback to ap_errorlog_provider

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

591 *) mod_auth_digest: Use the secret when generating nonces in all cases and
592 not only when AuthName is used in .htaccess files (this change may cause

594 secret on graceful restarts. PR 54637 [Stefan Fritsch]
596 *) core: Stop the HTTP_IN filter from attempting to write error buckets
