2 Changes with Apache 2.5.1
3 *) ru, zh-cn and zh-tw translations of errordocs have been added.
4 Contributed by Alexander Gaganashvili and CodeingBoy
6 *) mod_authz_core: If several parameters are used in a AuthzProviderAlias
7 directive, if these parameters are not enclosed in quotation mark, only
8 the first one is handled. The other ones are silently ignored.
9 Add a message to warn about such a spurious configuration.
10 PR 62469 [Hank Ibell <hwibell gmail.com>, Christophe Jaillet]
12 *) mod_proxy_wstunnel: Add default schema ports for 'ws' and 'wss'.
13 PR 62480. [Lubos Uhliarik <luhliari redhat.com>}
15 *) mod_ratelimit: fix behavior when proxing content. PR 62362.
16 [Yann Ylavic, Luca Toscano]
18 *) http: Fix small memory leak per request when handling persistent
19 connections. [Ruediger Pluem, Joe Orton]
21 *) mod_remoteip: Fix RemoteIP{Trusted,Internal}ProxyList loading broken by 2.4.30.
22 PR 62220. [Chritophe Jaillet, Yann Ylavic]
24 *) mod_userdir: If several directories are given in a UserDir directive, only files
25 in the first existing one are checked. If the file is not found there, the
26 other possible directories are not checked. The doc clearly states that they
27 will be checked one by one, until a match is found or an external redirect is
31 *) mod_proxy: Fix a corner case where the ProxyPassReverseCookieDomain or
32 ProxyPassReverseCookiePath directive could fail to update correctly
33 'domain=' or 'path=' in the 'Set-Cookie' header. PR 61560.
36 *) mod_slotmem_shm: Add generation number to shm filename to fix races
37 with graceful restarts. PRs 62044 and 62308. [Jim Jagielski, Yann Ylavic]
39 *) mod_rewrite: Only create the global mutex used by "RewriteMap prg:" when
40 this type of map is present in the configuration. PR62311.
41 [Hank Ibell <hwibell gmail.com>]
43 *) mod_ldap: Abort on LDAP locking errors. [Eric Covener]
45 *) mod_ssl: Support loading certificates and private keys from the
46 PKCS#11 OpenSSL engine. [Anderson Sasaki <ansasaki redhat.com>,
49 *) mod_proxy_html: Fix variable interpolation and memory allocation failure
50 in ProxyHTMLURLMap. [Ewald Dieterich <ewald mailbox.org>]
52 *) core: In ONE_PROCESS/debug mode, cleanup everything when exiting.
55 *) mod_http2: adding an abort function to slave connections' pools, so out-of-memory
56 events lead to a control process abort, as on HTTP/1.x connections. [Stefan Eissing]
58 *) mod_http2: adding regular memory cleanup when transferring large response bodies. This
59 reduces memory footprint and avoids memory exhaustion when transferring large files
60 on 32-bit architectures. Fixes PR 62325. [Stefan Eissing]
62 *) http: LimitRequestBody applies to proxied requests. [Yann Ylavic]
64 *) mod_logio: Add LogIOTrackTTFU and %^FU logformat to log the time
65 difference between request start and last request body byte read (finished upload).
68 *) mod_ssl: add support for TLSv1.3 (tested with OpenSSL v1.1.1-pre4, other libs may
69 need more sugar). SSL(Proxy)CipherSuite now has an optional first parameter for the
70 protocol the ciphers are for.
71 Directive "SSLVerifyClient" now triggers certificate retrieval from the client (this
72 is not fully tested - but fails in similar fashion as in TLSv1.2 in my setups).
73 Verifying the client fails exactly the same for HTTP/2 connections for all SSL protocols,
74 as this would need to trigger the master connection thread - which we do not support
76 Renegotiation of ciphers is intentionally ignored for TLSv1.3 connections. "SSLCipherSuite"
77 does not allow to specify TLSv1.3 ciphers in a directory context (because it cannot work) and
78 TLSv1.2 or lower ciphers are not relevant, as cipher suites are completely separate.
79 This means there is a bit if a world split when simultaneously having TLSv1.2 and TLSv1.3
80 connections to the same server.
83 *) mod_ssl: proper checks for libressl 2.07/8 and its TLSv1_3 support, see PR 62236.
84 [Bernard Spil <brnrd@freebsd.org>]
86 *) mod_http2: on level trace2, log any unsuccessful HTTP/2 direct connection upgrade
87 with base64 encoding to unify its appearance in possible bug reports. [Stefan Eissing]
89 *) mod_cgi: Add CGIScriptTimeout to make mod_cgi's timeout per-directory and
90 independent of the core Timeout directive. PR 62229.
91 [Hank Ibell <hwibell gmail.com>]
93 *) mod_ssl: heavily simplified SSLPolicy. No more user defines, no propxy policies,
94 just the basic "modern", "intermediate" and "old" as specified by Mozilla security.
97 *) mod_md: fixes error in renew window calculation that may lead to mod_md running
98 watchdog in a tight loop until actual renewal becomes necessary. [Stefan Eissing]
100 *) mod_md: /.well-known/acme-challenge requests that cannot be answered for hostnames
101 outside the configured MDs are free to be answered by other handlers. This allows
102 co-existance between mod_md and other ACME clients on the same server (implements PR62189).
103 [Stefan Eissing, Arkadiusz Miskiewicz <arekm@maven.pl>]
105 *) core: Create a conn_config_t structure to hold an extendable core config rather
106 than consuming the whole pointer with the connection socket. [Graham Leggett]
108 *) core: adding AP_DECLARE for ap_parse_vhost_addrs() and minor bumb mmn. Resolves
109 building mod_ssl on Windows. [Stefan Eissing, Gregg Smith]
111 *) mod_http2: discourage gzip/brotli content encoding on http2-status responses as
112 they are inserted into the reponse when filters are already done. [Stefan Eissing]
114 *) core: adding defines to allow interworking with honggfuzz without
115 further patches. [Stefan Eissing, Robert Swiecki]
117 *) mod_headers: 'RequestHeader set|edit|edit_r Content-Type X' could
118 inadvertently modify the Content-Type _response_ header. Applies to
119 Content-Type only and likely to only affect static file responses.
122 *) mod_cgi: Improve AH01215 messages to make it more clear that the message is
123 the CGI scripts stderr output. PR 61980. [Hank Ibell <hwibell gmail.com>]
125 *) mod_headers: Allow 'Header unset Content-Type' to remove the Content-Type
126 header. PR 61983. [Hank Ibell <hwibell gmail.com>]
128 *) mod_md v1.1.8: new configuration directive "MDBaseServer on|off" to allow/inhibit
129 management of the base server domains outside VirtualHosts. By default, this is "off",
130 e.g. mod_md will not manage certificates or perform https: redirections on the
131 base server. [Stefan Eissing]
133 *) core: Add "AcceptErrorsNonFatal" to allow ECONNREFUSED, ECONNABORTED, and
134 ECONNRESET during the client accept() to not trigger graceful shutdown of
135 the child process. [Eric Covener]
138 - MDMustStaple was unable to create the necessary OpenSSL OBJ identifier on some platforms,
139 possibly because this fails if the OID is already configured in ```openssl.cnf```, see
140 [here](https://github.com/openssl/openssl/issues/2795).
141 - Two memory leaks in cert issuer and alt-names lookup eliminated by Yann Ylavic.
142 - Changing MDMustStaple triggers certificate renewal.
143 - More verbosity when *not* handing out certificates, e.g. mod_ssl asks, but mod_md has no
144 idea what it is talking about. Some people report misbehaviour here.
145 - Re-enabled support for md_get_credentials() function that was used in older mod_ssl
146 patch, so that people with old patched servers get a chance to upgrade.
147 [Stefan Eissing, Yann Ylavic]
149 *) mod_susbtitute: Allow expressions in the subtitution, prefixed with expr=
152 *) mod_md: fixed mem pool usage for auto-added server names. Added
153 error logging of exact ACME response when challenges failed.
156 *) mod_md: reverses most of v1.0.5 optimization of post_config init, so that
157 mod_ssl can ask for certiticates without crashing. [Stefan Eissing]
159 *) mod_proxy: allow SSLProxyCheckPeer* usage for all proxy modules.
160 PR 61857. [Yann Ylavic]
162 *) mod_proxy_html: fix handling of <meta http-equiv> elements.
165 *) mod_md: fixed backward compatibility to old <ManagedDomain configuration.
166 Add higher level WARNING log when initial request to ACME server fails, mentioning
167 some advice. [Stefan Eissing]
169 *) mod_md: name change in configuration directives. The old names are still working
170 in this version, so you can safely upgrade. They will give warnings in the log and
171 will disappear in the immediate future. ManagedDomain is now MDomain,
172 <ManagedDomain> is now <MDomainSet>. [Stefan Eissing]
174 *) mod_ssl: renamed section <SSLPolicy to <SSLPolicyDefine. Fixed behaviour
175 for new server config merge flag. Denying global, only once used directives
176 inside a SSLPolicyDefine. [Stefan Eissing]
178 *) mod_auth_basic: Be less tolerant when parsing the credencial. Only spaces
179 should be accepted after the authorization scheme. \t are also tolerated.
182 *) mod_http2: fixed unfair scheduling when number of active connections
183 exceeded the scheduling fifo capacity. [Stefan Eissing]
185 *) core: Support zone/scope in IPv6 link-local addresses in Listen and
186 VirtualHost directives (requires APR 1.7.x or later). PR 59396. [Joe Orton]
188 *) mod_md: v1.0.5, restricting post_config dry run to be more silent and performing
189 only necessary work for mod_ssl to be also happy with the configuration.
192 *) mod_md: v1.0.4, removed the 'a2md' utility command from build. Only used in github
193 testing. Avoid problems with our build system that had problems after the latest
194 changes to make a clean initial build. Remove the windows a2md.dsp therefore also.
197 *) mod_ssl: Fail with 403 if the username for FakeBasicAuth mode
198 includes a colon character. PR 52644. [Joe Orton]
200 *) mod_md: v1.0.3, fixed various bugs in persisting job properties, so that status is
201 persisted accross child process changes and staging is reset on reloads. Changed
202 MDCertificateAgreement url checks. As long as the CA reports that the account has
203 an agreement, no further checking is done. Existing accounts need no changes when
204 a new agreement comes out. [Stefan Eissing]
206 *) mod_watchdog: Correct some log messages. [Rainer Jung]
208 *) mod_noloris: complete build setup. [Rainer Jung]
210 *) mod_md: fix static compilation. [Rainer Jung]
212 *) mod_md: fix compilation of helper binary a2md. [Rainer Jung]
214 *) core: fix pcre feature detection in configure when using pcre2. [Rainer Jung]
216 Changes with Apache 2.5.0-alpha
218 *) mod_md: v1.0.1, ServerName/Alias names from pure-http: virtual hosts are no longer
219 auto-added to a Managed Domain. Error counts of jobs are presisted. When the server
220 restarts (gracefully) any errored staging areas are purged to reset the signup/renewal
221 process. [Stefan Eissing]
223 *) mod_md: v1.0.0, new config directive 'MDNotifyCmd' to hook in a program when Managed
224 Domains have obtained/renewed their certificates successfully. [Stefan Eissing]
226 *) mod_md: v0.9.9, fix for applying challenge type based on available ports. [Stefan Eissing]
229 - Use of the new module flag
230 - Removed obsolete function from interface to mod_ssl.
231 - Fallback certificates has version set and no longer claims to be a CA. (re issue #32)
232 - MDRequireHttps now happens before any Redirect.
235 *) mod_ssl: unshare SSLSrvConfigRec instances between base server and virtual hosts. This avoids
236 overwrites of later initializattions (vhost_id), selective disables by "SSLEngine addr-list"
237 and certificate/key pickup from mod_md. [Stefan Eissing]
239 *) mod_md: v0.9.6: a "MDRequireHttps permament" configured domain automatically sends out
240 HSTS (rfc 6797) headers in https: responses. [Stefan Eissing]
242 *) mod_ssl: adding ssl_policies.h[.in] for policy cipher/protocol definitions. Use
243 update_policies.py to update manually from Mozilla JSON definitions at
244 https://statics.tls.security.mozilla.org/server-side-tls-conf.json
248 - New directive (srly: what do you expect at this point?) "MDMustStaple on|off" to control if
249 new certificates are requested with the OCSP Must Staple extension.
250 - Known limitation: when the server is configured to ditch and restart child processes, for example
251 after a certain number of connections/requests, the mod_md watchdog instance might migrate
252 to a new child process. Since not all its state is persisted, some messsages might appear a
253 second time in the logs.
254 - Adding checks when 'MDRequireHttps' is used. It is considered an error when 'MDPortMap 443:-'
255 is used - which negates that a https: port exists. Also, a warning is logged if no
256 VirtualHost can be found for a Managed Domain that has port 443 (or the mapped one) in
258 - New directive 'MDRequireHttps' for redirecting http: traffic to a Managed Domain, permanently
260 - Fix for using a fallback certificate on initial signup of a Managed Domain. Requires also
261 a changed mod_ssl patch (v5) to take effect.
262 - compatibility with libressl
265 *) mod_md: v0.9.2: new directive 'MDHttpProxy' to define a proxy for outgoing connection,
266 some minor bugfixes, twiddle the build system to avoid non-pic code generation.
270 - various fixes in MDRenewWindow handling when specifying percent. Serialization changed. If
271 someone already used percent configurations, it is advised to change these to a new value,
272 reload and change back to the wanted ones.
273 - various fixes in handling of MDPrivateKeys when specifying 2048 bits (the default) explicitly.
274 - mod_md version removed from top level md_store.json file. The store has its own format version
275 to facilitate upgrades.
279 Certificate provisioning from Let's Encrypt (and other ACME CAs) for mod_ssl virtual hosts.
282 *) mod_ssl: add SSLPolicy (define/use) and SSLProxyPolicy directives plus documentation. Add
283 core definitions for policies 'modern', 'intermediate' and 'old', as defined by Mozilla
284 in <https://wiki.mozilla.org/Security/Server_Side_TLS>. [Stefan Eissing]
286 *) mod_md: new module for managing domains across VirtualHosts with ACME protocol
287 implementation for automated certificate signup and renewal. Default CA is
288 the test area of Let's Encrypt right now, so certificates root will not be valid.
289 Will be switched to the real service endpoint rather soon. If you need it now,
290 configure 'MDCertificateAuthority https://acme-v01.api.letsencrypt.org/directory'.
293 *) mod_rewrite: Add 'RewriteOptions LongURLOptimization' to free memory
294 from each set of unmatched rewrite conditions.
297 *) Allow the argument to <IfFile>, <IfDefine>, <IfSection>, <IfDirective>,
298 and <IfModule> to be quoted. This is primarily for the benefit of
299 <IfFile>. [Eric Covener]
301 *) Introduce request taint checking framework to prevent privilege
302 hijacking through .htaccess. [Nick Kew]
304 *) Add <IfDirective> and <IfSection> directives. [Joe Orton]
306 *) When using mod_status with the Event MPM, report the number of requests
307 associated with an active connection in the "ACC" field. Previously
308 zero was always reported with this MPM. PR60647. [Eric Covener]
310 *) mod_remoteip: When overriding the useragent address from X-Forwarded-For,
311 zero out what had been initialized as the connection-level port. PR59931.
312 [Hank Ibell <hwibell gmail.com>]
314 *) mod_proxy_wstunnel: Reliably run before mod_proxy_http.
317 *) http: Allow unknown response status' lines returned in the form of
318 "HTTP/x.x xxx Status xxx". [Yann Ylavic]
320 *) core: Add <IfFile> configuration section to allow any file on disk to be
321 used as a conditional. [Edward Lu, Eric Covener]
323 *) mod_crypto: Add the all purpose crypto filters with support for HLS.
326 *) core: Drop an invalid Last-Modified header value coming
327 from a FCGI/CGI script instead of replacing it with Unix epoch.
328 Warn the users about Last-Modified header value replacements
329 and violations of the RFC.
330 [Yann Ylavic, Luca Toscano, William Rowe, Jacob Champion]
332 *) mod_dav: Allow other modules to become providers and add ACLs
334 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
336 *) mod_dav: Add dav_begin_multistatus, dav_send_one_response,
337 dav_finish_multistatus, dav_send_multistatus, dav_handle_err,
338 dav_failed_proppatch, dav_success_proppatch to mod_dav.h.
339 [Jari Urpalainen <jari.urpalainen nokia.com>, Graham Leggett]
341 *) core: explicitly exclude 'h2' from protocols announced via an Upgrade:
342 header as commanded by http-wg. [Stefan Eissing]
344 *) mod_proxy_ajp: Add "secret" parameter to proxy workers to implement legacy
345 AJP13 authentication. PR 53098. [Dmitry A. Bakshaev <dab1818 gmail com>]
347 *) mpm: Generalise the ap_mpm_register_socket functions to accept pipes
348 or sockets. [Graham Leggett]
350 *) core: Extend support for setting aside data from the network input filter
351 to any connection or request input filter. [Graham Leggett]
353 *) core: Split ap_create_request() from ap_read_request(). [Graham Leggett]
355 *) mod_auth_digest: Fix compatibility with expression-based Authname. PR59039.
358 *) mpm: Add a complete_connection hook that confirms whether an MPM is allowed
359 to leave the WRITE_COMPLETION phase. Move filter code out of the MPMs.
362 *) mod_cache: Consider Cache-Control: s-maxage in expiration
363 calculations. [Eric Covener]
365 *) mod_cache: Allow caching of responses with an Expires header
366 in the past that also has Cache-Control: max-age or s-maxage.
367 PR55156. [Eric Covener]
369 *) mod_session: Introduce SessionExpiryUpdateInterval which allows to
370 configure the session/cookie expiry's update interval. PR 57300.
371 [Paul Spangler <paul.spangler ni.com>]
373 *) core: Extend support for asynchronous write completion from the
374 network filter to any connection or request filter. [Graham Leggett]
376 *) mod_auth_digest: remove AuthDigestEnableQueryStringHack which is no
377 more documented since dec 2012 (r1415960). [Christophe Jaillet]
379 *) mod_charset_lite: On EBCDIC platforms, make sure mod_charset_lite runs
380 after other resource-level filters. [Eric Covener]
382 *) http: Don't remove the Content-Length of zero from a HEAD response if
383 it comes from an origin server, module or script. [Yann Ylavic]
385 *) http: Add support for RFC2324/RFC7168. [Graham Leggett]
387 *) mod_authn_core: Add expression support to AuthName and AuthType.
390 *) suexec: Filter out the HTTP_PROXY environment variable because it is
391 treated as alias for http_proxy by some programs. [Stefan Fritsch]
393 *) mod_proxy_http: Don't establish or reuse a backend connection before pre-
394 fetching the request body, so to minimize the delay between it is supposed
395 to be alive and the first bytes sent: this is a best effort to prevent the
396 backend from closing because of idle or keepalive timeout in the meantime.
397 Also, handle a new "proxy-flushall" environment variable which allows to
398 flush any forwarded body data immediately. PR 56541+37920. [Yann Ylavic]
400 *) core: Define and UnDefine are no longer permitted in
401 directory context. Previously they would always be evaulated
402 as the configuration was read without regard for the directory
403 context. [Eric Covener]
405 *) config: For directives that do not expect any arguments, enforce
406 that none are specified in the configuration file.
407 [Joachim Zobel <jzobel heute-morgen.de>, Eric Covener]
409 *) mod_rewrite: Improve 'bad flag delimeters' startup error by showing
410 how the input was tokenized. PR 56528. [Edward Lu <Chaosed0 gmail.com>]
412 *) mod_proxy: Don't put non balancer-member workers in error state by
413 default for connection or 500/503 errors, and honor status=+I for
414 any error. PR 48388. [Yann Ylavic]
416 *) ap_expr: Add filemod function for checking file modification dates
419 *) mod_authnz_ldap: Resolve crashes with LDAP authz and non-LDAP authn since
420 r1608202. [Eric Covener]
422 *) apreq: Content-Length header should be always interpreted as a decimal.
423 Leading 0 could be erroneously considered as an octal value. PR 56598.
424 [Chris Card <ctcard hotmail com>]
426 *) mod_proxy: Now allow for 191 character worker names, with non-fatal
427 errors if name is truncated. PR53218. [Jim Jagielski]
429 *) mod_ssl: Add optional function "ssl_get_tls_cb" to allow support
430 for channel bindings. [Simo Sorce <simo redhat.com>]
432 *) mod_proxy_wstunnel: Concurrent websockets messages could be
433 lost or delayed with ProxyWebsocketAsync enabled.
434 [Edward Lu <Chaosed0 gmail.com>]
436 *) core, mod_info: Add compiled and loaded PCRE versions to version
437 number display. [Rainer Jung]
439 *) mod_authnz_ldap: Return LDAP connections to the pool before the handler
440 is run, instead of waiting until the end of the request. [Eric Covener]
442 *) mod_proxy_html: support automatic detection of doctype and processing
443 of FPIs. PR56285 [Micha Lenk <micha lenk info>, Nick Kew]
445 *) core: Add ap_mpm_resume_suspended() API to allow a suspended connection
447 [Artem <artemciy gmail.com>, Edward Lu <Chaosed0 gmail.com>]
449 *) core: Add ap_mpm_register_socket_callback_timeout() API. [Eric Covener]
451 *) mod_proxy_wstunnel: Honor ProxyWebsocketIdleTimeout in asynchronous
452 processing mode. [Eric Covener]
454 *) mod_authnz_ldap: Fail explicitly when the filter is too long. Remove
455 unnecessary apr_pstrdup() and strlen(). [Graham Leggett]
457 *) Add the ldap-search option to mod_authnz_ldap, allowing authorization
458 to be based on arbitrary expressions that do not include the username.
461 *) Add the ldap function to the expression API, allowing LDAP filters and
462 distinguished names based on expressions to be escaped correctly to
463 guard against LDAP injection. [Graham Leggett]
465 *) Add module mod_ssl_ct, which provides an implementation of Certificate
466 Transparency (RFC 6962) for httpd. [Jeff Trawick]
468 *) mod_proxy_wstunnel: Avoid sending error responses down an upgraded
469 websockets connection as it is being close down. [Eric Covener]
471 *) mod_proxy_wstunnel: Allow the administrator to cap the amount
472 of time a synchronous websockets connection stays idle with
473 ProxyWebsocketIdleTimeout. [Eric Covener]
475 *) mod_proxy_wstunnel: Change to opt-in for asynchronous support, adding
476 directives ProxyWebsocketAsync and ProxyWebsocketAsyncDelay.
479 *) mod_proxy_wstunnel: Stop leaking websockets backend connections under
480 event MPM (trunk-only). [Eric Covener]
482 *) mod_proxy_http: Add detach_backend hook (potentially usable
483 in other proxy scheme handlers). [Jeff Trawick]
485 *) mod_deflate: Add DeflateAlterETag to control how the ETag
486 is modified. The 'NoChange' parameter mimics 2.2.x behavior.
487 PR 45023, PR 39727. [Eric Covener]
489 *) mod_dir: Default to 2.2-like behavior and skip execution when method is
490 neither GET nor POST, such as for DAV requests. PR 54914. [Chris Darroch]
492 *) mod_rewrite: Rename the handler that does per-directory internal
493 redirects to "rewrite-redirect-handler" from "redirect-handler" so
494 it is less ambiguous and less likely to be reused. [Eric Covener]
496 *) mod_rewrite: Protect against looping with the [N] flag by enforcing a
497 default limit of 10000 iterations, and allowing each rule to change its
498 limit. [Eric Covener]
500 *) mod_ssl: Fix config merging of SSLOCSPEnable and SSLOCSPOverrideResponder.
503 *) Add HttpContentLengthHeadZero and HttpExpectStrict directives.
504 [Yehuda Sadeh <yehuda inktank com>, Justin Erenkrantz]
506 *) mod_ssl: Add -t -DDUMP_CA_CERTS option which dumps the filenames of all
507 configured SSL CA certificates to stdout the same way as DUMP_CERTS does.
510 *) mod_ssl: Don't flush when an EOS is received. Prepares mod_ssl
511 to support write completion. [Graham Leggett]
513 *) core: Add parse_errorlog_arg callback to ap_errorlog_provider
514 to allow providers to check the ErrorLog argument. [Jan Kaluza]
516 *) mod_cgid: Use the servers Timeout for each read from a CGI script,
517 allow override with new CGIDRequestTimeout directive. PR43494
518 [Eric Covener, Toshikuni Fukaya <toshikuni-fukaya cybozu co jp>]
520 *) core: ensure any abnormal exit is reported to stderr if it's a tty.
523 *) mod_lua: Let the Inter-VM get/set functions work with a global
524 shared memory pool instead of a per-process pool. [Daniel Gruno]
526 *) ldap: Support ldaps when using the Microsoft LDAP SDK.
527 PR 54626. [Jean-Frederic Clere]
529 *) mod_authnz_ldap: Change default value of AuthLDAPMaxSubGroupDepth to 0
530 to avoid performance problems when subgroups aren't in use. [Eric Covener]
532 *) mod_syslog: New module implementing syslog ap_error_log provider.
533 Previously, this code was part of core, now it's in separate module.
536 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
537 syslog support from core to new mod_syslog. [Jan Kaluza]
539 *) mod_status, mod_echo: Fix the display of client addresses.
540 They were truncated to 31 characters which is not enough for IPv6 addresses.
541 PR 54848 [Bernhard Schmidt <berni birkenwald de>]
543 *) core: merge AllowEncodedSlashes from the base configuration into
544 virtual hosts. [Eric Covener]
546 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
549 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
552 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
553 been configured with -D Z_PREFIX, which redefines the token "deflate".
556 *) mod_auth_digest: Use the secret when generating nonces in all cases and
557 not only when AuthName is used in .htaccess files (this change may cause
558 problems if used with round robin load balancers). Don't regenerate the
559 secret on graceful restarts. PR 54637 [Stefan Fritsch]
561 *) core: Stop the HTTP_IN filter from attempting to write error buckets
562 to the output filters, which is bogus in the proxy case. Create a
563 clean mapping from APR codes to HTTP status codes, and use it where
564 needed. [Graham Leggett]
566 *) mod_proxy: Ensure network errors detected by the proxy are returned as
567 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
568 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
570 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
571 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
572 <alejandro.alvarez.ayllon cern.ch>]
574 *) mod_ldap: LDAP connections used for authentication were not respecting
575 LDAPConnectionPoolTimeout. PR 54587
577 *) core: Add option to add valgrind support. Use it to reduce false positive
578 warnings in mod_ssl. [Stefan Fritsch]
580 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
581 Cache the result of the most recent password hash verification for every
582 keep-alive connection. This saves some expensive calculations.
585 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
586 MSIE 3. [Stefan Fritsch]
588 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
589 conformance or to only log the found problems. [Stefan Fritsch]
593 *) core: Add LogLevelOverride directive that allows to override the
594 loglevel for clients from certain IPs. This also works for things
595 like the SSL handshake where <If> LogLevel ... </If> is evaluated
596 too late. [Stefan Fritsch]
598 *) core: Add new directive Warning to issue warnings from a configuration
599 file. Both Warning and Error now generate a timestamped log message.
602 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
603 variables. [Stefan Fritsch]
605 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
606 support. [Stefan Fritsch]
608 *) mod_allowhandlers: New module to forbid specific handlers for specific
609 directories. [Stefan Fritsch]
611 *) mod_systemd: New module, for integration with systemd on Linux.
612 [Jan Kaluza <jkaluza redhat.com>]
614 *) WinNT MPM: Store pid and generation for each thread in scoreboard
615 to allow tracking of threads from exiting children via mod_status
616 or other such mechanisms. [Jeff Trawick]
618 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
619 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
620 - mod_cache: thundering herd lock directory
621 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
622 - mod_ldap: shared memory cache
623 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
626 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
627 [Matthew Steele <mdsteele google.com>]
629 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
630 be compiled by the build compiler instead of the host compiler.
631 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
632 PR 51257. [Guenter Knauf]
634 *) core: In maintainer mode, replace apr_palloc with a version that
635 initializes the allocated memory with non-zero values, except if
636 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
638 *) mod_policy: Add a new testing module to help server administrators
639 enforce a configurable level of protocol compliance on their
640 servers and application servers behind theirs. [Graham Leggett]
642 *) mod_firehose: Add a new debugging module able to record traffic
643 passing through the server in such a way that connections and/or
644 requests be reconstructed and replayed. [Graham Leggett]
