3 Changes with Apache 2.4.24
5 *) mpm_unix: Apache fails to start if previously crashed then restarted with
6 the same PID (e.g. in container). PR 60261.
7 [Val <valentin.bremond gmail.com>, Yann Ylavic]
9 *) mod_http2: unannounced and multiple interim responses (status code < 200)
10 are parsed and forwarded to client until a final response arrives.
13 *) mod_proxy_http2: improved robustness when main connection is closed early
14 by resetting all ongoing streams against the backend.
17 *) mod_http2: allocators from slave connections are released earlier, resulting
18 in less overall memory use on busy, long lived connections.
21 *) mod_remoteip: Pick up where we left off during a subrequest rather
22 than running with the modified XFF but original TCP address.
25 *) mod_http2: connection shutdown revisited: corrected edge cases on
26 shutting down ongoing streams, changed log warnings to be less noisy
27 when waiting on long running tasks. [Stefan Eissing]
29 *) mod_http2: changed all AP_DEBUG_ASSERT to ap_assert to have them
30 available also in normal deployments. [Stefan Eissing]
32 *) mod_http2/mod_proxy_http2: 100-continue handling now properly implemented
33 up to the backend. Reused HTTP/2 proxy connections with more than a second
34 not used will block request bodies until a PING answer is received.
35 Requests headers are not delayed by this, since they are repeatable in
36 case of failure. This greatly increases robustness, especially with
37 busy server and/or low keepalive connections. [Stefan Eissing]
39 *) mod_proxy_http2: fixed duplicate symbols with mod_http2.
42 *) mod_http2: rewrite of how responses and trailers are transferred between
43 master and slave connection. Reduction of internal states for tasks
44 and streams, stability. Heuristic id generation for slave connections
45 to better keep promise of connection ids unique at given point int time.
46 Fix for mod_cgid interop in high load situtations.
47 Fix for handling of incoming trailers when no request body is sent.
50 *) mod_http2: fix suspended handling for streams. Output could become
51 blocked in rare cases. [Stefan Eissing]
53 *) mpm_winnt: Prevent a denial of service when the 'data' AcceptFilter is in
54 use by replacing it with the 'connect' filter. PR 59970. [Jacob Champion]
56 *) mod_cgid: Resolve a case where a short CGI response causes a subsequent
57 CGI to be killed prematurely, resulting in a truncated subsequent
58 response. [Eric Covener]
60 *) mod_proxy_hcheck: Set health check URI and expression correctly for health
61 check worker. PR 60038 [zdeno <zdeno@scnet.sk>]
63 *) mod_http2: if configured with nghttp2 1.14.0 and onward, invalid request
64 headers will immediately reset the stream with a PROTOCOL error. Feature
65 logged by module on startup as 'INVHD' in info message.
68 *) mod_http2: fixed handling of stream buffers during shutdown.
71 *) mod_reqtimeout: Fix body timeout disabling for CONNECT requests to avoid
72 triggering mod_proxy_connect's AH01018 once the tunnel is established.
75 *) ab: Set the Server Name Indication (SNI) extension on outgoing TLS
76 connections (unless -I is specified), according to the Host header (if
77 any) or the requested URL's hostname otherwise. [Yann Ylavic]
79 *) mod_proxy_fcgi: avoid loops when ProxyErrorOverride is enabled
80 and the error documents are proxied. PR 55415. [Luca Toscano]
82 *) mod_proxy_fcgi: read the whole FCGI response even when the content has
83 not been modified (HTTP 304) to avoid subsequent bougus reads and
84 confusing error messages logged. [Luca Toscano]
86 *) mod_http2: h2 status resource follows latest draft, see
87 http://www.ietf.org/id/draft-benfield-http2-debug-state-01.txt
90 *) mod_http2: handling graceful shutdown gracefully, e.g. handling existing
91 streams to the end. [Stefan Eissing]
93 *) core: CVE-2016-5387: Mitigate [f]cgi "httpoxy" issues.
94 [Dominic Scheirlinck <dominic vendhq.com>, Yann Ylavic]
96 *) mod_proxy_{http,ajp,fcgi}: don't reuse backend connections with data
97 available before the request is sent. PR 57832. [Yann Ylavic]
99 *) mod_proxy_balancer: Prevent redirect loops between workers within a
100 balancer by limiting the number of redirects to the number balancer
101 members. PR 59864 [Ruediger Pluem]
103 *) mod_proxy: Correctly consider error response codes by the backend when
104 processing failonstatus. PR 59869 [Ruediger Pluem]
106 *) mod_dav: Add dav_get_provider_name() function to obtain the name
107 of the provider from mod_dav. [Graham Leggett]
109 *) mod_dav: Add support for childtags to dav_error.
110 [Jari Urpalainen <jari.urpalainen nokia.com>]
112 *) mod_proxy_fcgi: Fix 2.4.23 breakage for mod_rewrite per-dir and query
113 string showing up in SCRIPT_FILENAME. PR59815
115 *) mod_include: Fix a potential memory misuse while evaluating expressions.
116 PR59844. [Eric Covener]
118 *) mod_http2: new H2CopyFiles directive that changes treatment of file
119 handles in responses. Necessary in order to fix broken lifetime handling
120 in modules such as mod_wsgi.
122 *) mod_http2: removing timeouts on master connection while requests are
123 being processed. Requests may timeout, but the master only times out when
124 no more requests are active. [Stefan Eissing]
126 *) mod_http2: fixes connection flush when answering SETTINGS without any
127 stream open. [Moto Ishizawa <@summerwind>, Stefan Eissing]
129 Changes with Apache 2.4.23
131 *) mod_ssl: reset client-verify state of ssl when aborting renegotiations.
132 [Erki Aring <erki@example.ee>, Stefan Eissing]
134 *) mod_sed: Fix 'x' command processing. [Christophe Jaillet]
136 *) configure: Fix ./configure edge-case failures around dependencies
137 of mod_proxy_hcheck. [William Rowe, Ruediger Pluem, Jeff Trawick]
139 Changes with Apache 2.4.22
141 *) mod_http2: fix for request abort when connections drops, introduced in
144 Changes with Apache 2.4.21
146 *) mod_http2: more rigid error handling in DATA frame assembly, leading
147 to deterministic connection errors if assembly fails.
148 [Stefan Eissing, Pal Nilsen <https://github.com/maedox>]
150 *) abs: Include OPENSSL_Applink when compiling on Windows, to resolve
151 failures under Visual Studio 2015 and other mismatched MSVCRT flavors.
152 PR59630 [Jan Ehrhardt <phpdev ehrhardt.nl>]
154 *) mod_ssl: Add "no_crl_for_cert_ok" flag to SSLCARevocationCheck directive
155 to opt-in previous behaviour (2.2) with CRLs verification when checking
156 certificate(s) with no corresponding CRL. [Yann Ylavic]
158 *) mpm_event, mpm_worker: Fix computation of MinSpareThreads' lower bound
159 according the number of listeners buckets. [Yann Ylavic]
161 *) Add ap_cstr_casecmp[n]() - placeholder of apr_cstr_casecmp[n] functions
162 for case-insensitive C/POSIX-locale token comparison.
163 [Jim Jagielski, William Rowe, Yann Ylavic, Branko Čibej]
165 *) mod_userdir: Constify and save a few bytes in the conf pool when
166 parsing the "UserDir" directive. [Christophe Jaillet]
168 *) mod_cache: Fix (max-stale with no '=') and enforce (check
169 integers after '=') Cache-Control header parsing.
172 *) core: Add -DDUMP_INCLUDES configtest option to show the tree
173 of Included configuration files.
174 [Jacob Champion <champion.pxi gmail.com>]
176 *) mod_proxy_fcgi: Avoid passing a filename of proxy:fcgi:// as
177 SCRIPT_FILENAME to a FastCGI server. PR59618.
178 [Jacob Champion <champion.pxi gmail.com>]
180 *) mod_dav: Add dav_get_provider_name() function to obtain the name
181 of the provider from mod_dav.
182 [Jari Urpalainen <jari.urpalainen nokia.com>]
184 *) mod_proxy_http2: properly care for HTTP2 flow control of the frontend
185 connection is HTTP/1.1. [Patch supplied by Evgeny Kotkov]
187 *) mod_http2: improved cleanup of connection/streams/tasks to always
188 have deterministic order regardless of event initiating it. Addresses
189 reported crashes due to memory read after free issues.
192 *) mod_ssl: Correct the interaction between SSLProxyCheckPeerCN and newer
193 SSLProxyCheckPeerName directives since release 2.4.5, such that disabling
194 either disables both, and that enabling either triggers the new, more
195 comprehensive SSLProxyCheckPeerName behavior. Only a single configuration
196 remains to enable the legacy behavior, which is to explicitly disable
197 SSLProxyCheckPeerName, and enable SSLProxyCheckPeerCN. [William Rowe]
199 *) mod_include: add the <!--#comment ...> syntax in order to include comments
200 in a SSI file. [Christophe Jaillet based on a suggestion from Rob]
202 *) mod_http2: improved event handling for suspended streams, responses
203 and window updates. [Stefan Eissing]
205 *) mod_proxy_hcheck: Provide for dynamic background health
206 checks on reverse proxies associated with BalancerMember
207 workers. [Jim Jagielski]
209 *) mod_http2: Fix async write issue that led to selection of wrong timeout
210 vs. keepalive timeout selection for idle sessions. [Stefan Eissing]
212 *) mod_http2: checking LimitRequestLine, LimitRequestFields and
213 LimitRequestFieldSize configurated values for incoming streams. Returning
214 HTTP status 431 for too long/many headers fields and 414 for a too long
215 pseudo header. [Stefan Eissing]
217 *) mod_http2: tracking conn_rec->current_thread on slave connections, so
218 that mod_lua finds the correct one. Fixes PR 59542. [Stefan Eissing]
220 *) mod_proxy_http2: new experimental http2 proxy module for h2: and h2c: proxy
221 urls. Part of the httpd mod_proxy framework, common settings apply.
222 Requests from the same HTTP/2 frontend connection against the same backend
223 are aggregated on a single connection.
226 *) mod_http2: slave connections have conn_rec->aborted flag set when a stream
227 has been reset by the client. [Stefan Eissing]
229 *) mod_http2: merge of some 2.4.x adaptions re filters on slave connections.
230 Small fixes in bucket beams when forwarding file buckets. Output handling
231 on master connection uses less FLUSH and passes automatically when more
232 than half of H2StreamMaxMemSize bytes have accumulated.
233 Workaround for http: when forwarding partial file buckets to keep the
234 output filter from closing these too early. [Stefan Eissing]
236 *) mod_http2: elimination of fixed master connection buffer for TLS
237 connections. New scratch bucket handling optimized for TLS write sizes.
238 File bucket data read directly into scratch buffers, avoiding one
239 copy. Non-TLS connections continue to pass buckets unchanged to the core
240 filters to allow sendfile() usage. [Stefan Eissing]
242 *) mod_http2/mod_proxy_http2: h2_request.c is no longer shared between these
243 modules. This simplifies building on platforms such as Windows, as module
244 reference used in logging is now clear. [Stefan Eissing]
246 *) Scoreboard: Fix a regression in 2.4.20 that causes wrong request data
247 to be displayed on the status page. PR 59333. [Yann Ylavic, William Rowe]
249 *) mod_http2: fixed a bug that caused mod_proxy_http2 to be called for window
250 updates on requests it had already reported done. Added synchronization
251 on early connection/stream close that lets ongoing requests safely drain
255 *) mod_http2: scoreboard updates that summarize the h2 session (and replace
256 the last request information) will only happen when the session is idle or
257 in shutdown/done phase. [Stefan Eissing]
259 *) mod_http2: new "bucket beam" technology to transport buckets across
260 threads without buffer copy. Delaying response start until flush or
261 enough body data has been accumulated. Overall significantly smaller
262 memory footprint. [Stefan Eissing]
264 *) core: New CGIVar directive can configure REQUEST_URI to represent the
265 current URI being processed instead of always the original request.
268 *) scoreboard/status: Restore behavior of showing workers' previous Client,
269 VHost and Request values when idle, like in 2.4.18 and earlier.
271 *) mod_http2: r->protocol changed to "HTTP/2.0" (was "HTTP/2") as this will
272 give expected syntax in CGI's SERVER_PROTOCOL is more compatible with
273 existing major/minor handling. Fixes PR 59313.
275 *) mod_http2: disabling mmap for file buckets transport due to segmenation
276 faults when files change on the fly.
278 Changes with Apache 2.4.20
280 *) SECURITY: CVE-2016-1546 (cve.mitre.org)
281 mod_http2: restricting number of concurrent stream workers per connection
284 *) core: Do not read .htaccess if AllowOverride and AllowOverrideList
285 are "None". PR 58528.
286 [Michael Schlenker <msc contact.de, Ruediger Pluem, Daniel Ruggeri]
288 *) mod_proxy_express: Fix possible use of DB handle after close. PR 59230.
289 [Petr <pgajdos suse.cz>]
291 *) core/util_script: relax alphanumeric filter of environment variable names
292 on Windows to allow '(' and ')' for passing PROGRAMFILES(X86) et.al.
293 unadulterated in 64 bit versions of Windows. PR 46751.
294 [John <john leineweb de>]
296 *) mod_http2: incrementing keepalives on each request started so that logging
297 %k gives increasing numbers per master http2 connection.
298 New documented variables in env, usable in custom log formats: H2_PUSH,
299 H2_PUSHED, H2_PUSHED_ON, H2_STREAM_ID and H2_STREAM_TAG.
302 *) mod_http2: more efficient passing of response bodies with less contention
303 and file bucket forwarding. [Stefan Eissing]
305 *) mod_http2: fix for missing score board updates on request count, fix for
306 memory leak on slave connection reuse. [Stefan Eissing]
308 *) mod_http2: Fix build on Windows from dsp files.
311 Changes with Apache 2.4.19
313 *) mod_include: Add variable DOCUMENT_ARGS, with the arguments to the
314 request for the SSI document. [Jeff Trawick]
316 *) mod_authz_host: Add a new "forward-dns" authorization type, not relying on
317 reverse DNS lookups. [Fabien]
319 *) mod_proxy_http2: new experimental http2 proxy module for h2: and h2c: proxy
320 urls. Uses backend connections for concurrent requests if frontend
321 connection is http2 as well.
324 *) mod_ssl: Add hooks to allow other modules to perform processing at
325 several stages of initialization and connection handling. See
326 mod_ssl_openssl.h. [Jeff Trawick]
328 *) mod_http2: disabling PUSH when client sends GOAWAY. Slave connections are
329 reused for several requests, improved performance and better memory use.
332 *) mod_rewrite: Don't implicitly URL-escape the original query string
333 when no substitution has changed it (like PR50447 but server context)
334 [Evgeny Kotkov <evgeny.kotkov visualsvn.com>]
336 *) mod_http2: fixes problem with wrong lifetime of file buckets on main
337 connection. [Stefan Eissing]
339 *) mod_http2: fixes incorrect denial of requests without :authority header.
342 *) mod_reqtimeout: Prevent long response times from triggering a timeout once
343 the request has been fully read. PR 59045. [Yann Ylavic]
345 *) ap_expr: expression support for variable HTTP2=on|off. [Stefan Eissing]
347 *) mod_http2: give control to async mpm for keepalive timeouts only when
348 no streams are open and even if only after 1 sec delay. Under load, event
349 mpm discards connections otherwise too quickly. [Stefan Eissing]
351 *) mod_ssl: Don't lose track of the SSL context if an unlikely failure occurs
352 in ssl_init_ssl_connection(). [Graham Leggett]
354 *) mod_rewrite: Add QSL|qslast flag to allow rewrites to files with
355 literal question marks in their names. PR 58777. [Eric Covener]
357 *) event: use pre_connection hook to properly initialize connection state for
358 slave connections. use protocol_switch hook to initialize server config
359 early based on SNI selected vhost.
362 *) hostname: Test and log useragent_host per-request across various modules,
363 including the scoreboard, expression and rewrite engines, setenvif,
364 authz_host, access_compat, custom logging, ssl and REMOTE_HOST variables.
365 PR55348 [William Rowe]
367 *) core: Track the useragent_host per-request when mod_remoteip or similar
368 modules track a per-request useragent_ip. Modules should be updated
369 to inquire for ap_get_useragent_host() in place of ap_get_remote_host().
372 *) core: fix a bug in <UnDefine ...> directive processing. When used, the last
373 <Define...>'ed variable was also withdrawn. PR 59019
376 *) mod_http2: Accept-Encoding is, when present on the initiating request,
377 added to push promises. This lets compressed content work in pushes.
378 by the client. [Stefan Eissing]
380 *) mod_http2: fixed possible read after free when streams were cancelled early
381 by the client. [Stefan Eissing]
383 *) mod_http2: fixed possible deadlock during connection shutdown. Thanks to
384 @FrankStolle for reporting and getting the necessary data.
387 *) mod_http2: fixed apr_uint64_t formatting in a log statement to user proper
388 APR def, thanks to @Sp1l.
390 *) mod_http2: number of worker threads allowed to a connection is adjusting
391 dynamically. Starting with 4, the number is doubled when streams can be
392 served without block on http/2 connection flow. The number is halfed, when
393 the server has to wait on client flow control grants.
394 This can happen with a maximum frequency of 5 times per second.
395 When a connection occupies too many workers, repeatable requests
396 (GET/HEAD/OPTIONS) are cancelled and placed back in the queue. Should that
397 not suffice and a stream is busy longer than the server timeout, the
398 connection will be aborted with error code ENHANCE_YOUR_CALM.
399 This does *not* limit the number of streams a client may open, rather the
400 number of server threads a connection might use.
403 *) mod_http2: allowing link header to specify multiple "rel" values,
404 space-separated inside a quoted string. Prohibiting push when Link
405 parameter "nopush" is present.
408 *) mod_http2: reworked connection state handling. Idle connections accept a
409 GOAWAY from the client without further reply. Otherwise the
410 module makes a best effort to send one last GOAWAY to the client.
412 *) mod_http2: the values from standard directives Timeout and KeepAliveTimeout
413 properly are applied to http/2 connections.
416 *) mod_http2: idle connections are returned to async mpms. new hook
417 "pre_close_connection" used to send GOAWAY frame when not already done.
418 Setting event mpm server config "by hand" for the main connection to
419 the correct negotiated server.
422 *) mod_http2: keep-alive blocking reads are done with 1 second timeouts to
423 check for MPM stopping. Will announce early GOAWAY and finish processing
424 open streams, then close.
427 *) mod_http2: bytes read/written on slave connections are reported via the
428 optional mod_logio functions. Fixes PR 58871.
430 *) prefork: Initialize the POD when running in ONE_PROCESS (or -X) mode to
431 avoid a crash. [Jan Kaluza, Yann Ylavic]
433 *) mod_ssl: When SSLVerify is disabled (NONE), don't force a renegotiation if
434 the SSLVerifyDepth applied with the default/handshaken vhost differs from
435 the one applicable with the finally selected vhost. [Yann Ylavic]
437 *) core: Ensure that httpd exits with an error status when the MPM fails
438 to run. [Yann Ylavic]
440 *) mod_ssl: Fix a possible memory leak on restart for custom [EC]DH params.
441 [Jan Kaluza, Yann Ylavic]
443 *) mod_ssl: Add SSLOCSPProxyURL to add the possibility to do all queries
444 to OCSP responders through a HTTP proxy. [Ruediger Pluem]
446 *) mod_proxy: Play/restore the TLS-SNI on new backend connections which
447 had to be issued because the remote closed the previous/reusable one
448 during idle (keep-alive) time. [Yann Ylavic]
450 *) mod_cache_socache: Fix a possible cached entity body corruption when it
451 is received from an origin server in multiple batches and forwarded by
452 mod_proxy. [Yann Ylavic]
454 *) core: Add expression support to SetHandler.
457 *) mod_remoteip: Prevent an external proxy from presenting an internal
458 proxy. PR 55962. [Mike Rumph]
460 *) core: Prevent a server crash in case of an invalid CONNECT request with
461 a custom error page for status code 400 that uses server side includes.
462 PR 58929 [Ruediger Pluem]
464 *) mod_ssl: handle TIMEOUT on empty SSL input as non-fatal, returning
465 APR_TIMEUP and preserving connection state for later retry.
468 *) mod_ssl: Save some TLS record (application data) fragmentations by
469 including the last and subsequent suitable buckets when coalescing.
472 *) mod_proxy_fcgi: Suppress HTTP error 503 and message 01075,
473 "Error dispatching request", when the cause appears to be
474 due to the client closing the connection.
475 PR58118. [Tobias Adolph <adolph lrz.de>]
477 *) mod_cgid: Message AH02550, failure to flush a response to the client,
478 is now logged at TRACE1 level to match the underlying core output filter
479 severity. [Eric Covener]
481 *) mime.types: add common extension "m4a" for MPEG 4 Audio.
482 PR 57895 [Dylan Millikin <dylan.millikin gmail.com>]
484 *) Added many log numbers to log statements that had none.
487 *) mod_log_config: Add GlobalLog to allow a globally defined log to
488 be inherited by virtual hosts that define a CustomLog.
491 *) mod_http2: connections how keep a "push diary" where hashes of already
492 pushed resources are kept. See directive H2PushDiarySize for managing this.
493 Push diaries can be initialized by clients via the "Cache-Digest" request
494 header. This carries a base64url encoded. compressed Golomb set as described
495 in https://datatracker.ietf.org/doc/draft-kazuho-h2-cache-digest/
496 Introduced a status handler for HTTP/2 connections, giving various counters
497 and statistics about the current connection, plus its cache digest value
498 in a JSON record. Not a replacement for more HTTP/2 in the server status.
500 <Location "/http2-status">
501 SetHandler http2-status
505 *) mod_http2: Fixed flushing of last GOAWAY frame. Previously, that frame
506 did not always reach the client, causing some to fail the next request.
507 Fixed calculation of last stream id accepted as described in rfc7540.
508 Reading in KEEPALIVE state now correctly shown in scoreboard.
509 Fixed possible race in connection shutdown after review by Ylavic.
510 Fixed segfault on connection shutdown, callback ran into a semi dismantled session.
513 *) mod_http2: Added support for experimental accept-push-policy draft
514 (https://tools.ietf.org/html/draft-ruellan-http-accept-push-policy-00). Clients
515 may now influence server pushes by sending accept-push-policy headers.
518 *) mod_http2: new r->subprocess_env variables HTTP2 and H2PUSH, set to "on"
519 when available for request.
522 *) mod_http2: fixed bug in input window size calculation by moving chunked
523 request body encoding into later stage of processing. Fixes PR 58825.
526 *) core: new hook "pre_close_connection" which is run before the lingering
527 close of connections is started. This gives protocol handlers one last
528 chance to use a connection before it goes down.
531 *) mod_status/scoreboard: showing connection protocol in new column, new
532 ap_update_child_status methods for updating server/description. mod_ssl
533 sets vhost negotiated by servername directly.
536 Changes with Apache 2.4.18
538 *) mod_ssl: for all ssl_engine_vars.c lookups, fall back to master connection
539 if conn_rec itself holds no valid SSLConnRec*. Fixes PR58666.
542 *) mod_http2: connection level window for flow control is set to protocol
543 maximum of 2GB-1, preventing window exhaustion when sending data on many
544 streams with higher cumulative window size.
545 Reducing write frequency unless push promises need to be flushed.
548 *) mod_http2: required minimum version of libnghttp2 is 1.2.1
551 *) mod_proxy_fdpass: Fix AH01153 error when using the default configuration.
552 In earlier version of httpd, you can explicitelly set the 'flusher' parameter
553 to 'flush' as a workaround. (i.e. flusher=flush)
554 Add documentation for the 'flusher' parameter when defining a proxy worker.
557 *) mod_ssl: For the "SSLStaplingReturnResponderErrors off" case, make sure
558 to only staple responses with certificate status "good". [Kaspar Brand]
560 *) mod_http2: new directive 'H2PushPriority' to allow priority specifications
561 on server pushed streams according to their content-type.
564 *) mod_http2: fixes crash on connection abort for a busy connection.
565 fixes crash on a request that did not produce any response.
568 *) mod_http2: trailers are sent after response body if set in request_rec
569 trailers_out before the end-of-request bucket is sent through the
570 output filters. [Stefan Eissing]
572 *) mod_http2: incoming trailers (headers after request body) are properly
573 forwarded to the processing engine. [Stefan Eissing]
575 *) mod_http2: new directive 'H2Push' to en-/disable HTTP/2 server
576 pushes a server/virtual host. Pushes are initiated by the presence
577 of 'Link:' headers with relation 'preload' on a response. [Stefan Eissing]
579 *) mod_http2: write performance of http2 improved for larger resources,
580 especially static files. [Stefan Eissing]
582 *) core: if the first HTTP/1.1 request on a connection goes to a server that
583 prefers different protocols, these protocols are announced in a Upgrade:
584 header on the response, mentioning the preferred protocols.
587 *) mod_http2: new directives 'H2TLSWarmUpSize' and 'H2TLSCoolDownSecs'
588 to control TLS record sizes during connection lifetime.
591 *) mod_http2: new directive 'H2ModernTLSOnly' to enforce security

603 server, the SSL parameters are checked for equality. With equal
604 configuration, requests are passed for processing. Any change will trigger
605 the old behaviour of "421 Misdirected Request".

3011 selection for 'most' more useful (including ssl and proxy). Both 'all'
3012 and 'most' will now disable modules if dependencies are missing instead
3013 of aborting. If a specific module is requested with --enable-XXX=yes,
3014 missing dependencies will still cause configure to exit with an error.

3148 mode that does not allow to bypass request access restrictions; new
3149 variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an
3150 alias for -U; an additional data entry in ap_expr_eval_ctx_t for use by

3209 the non-shared-memory cache as a workaround for the shared memory cache
3210 not being available during graceful restarts. PR 48958. [Stefan Fritsch]
3212 *) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,

4920 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
4921 The default is none as this is far greater debugging resolution than
4922 the typical administrator is prepared to untangle. [William Rowe]
4924 *) mod_disk_cache: If possible, check if the size of an object to cache is
4925 within the configured boundaries before actually saving data.
4926 [Niklas Edmundsson <nikke acc.umu.se>]
4928 *) Worker and event MPMs: Remove improper scoreboard updates which were
4929 performed in the event of a fork() failure. [Chris Darroch]
4931 *) Add support for fcgi:// proxies to mod_rewrite.
4932 [Markus Schiegl <ms schiegl.com>]
4934 *) Remove incorrect comments from scoreboard.h regarding conditional
4935 loading of worker_score structure with mod_status, and remove unused
4936 definitions relating to old life_status field.
4937 [Chris Darroch <chrisd pearsoncmg.com>]
4939 *) Remove allocation of memory for unused array of lb_score pointers
4940 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
4942 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
4943 [Garrett Rooney, Jim Jagielski, Paul Querna]
4945 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
4946 [Chris Darroch <chrisd pearsoncmg.com>]
4948 *) mod_charset_lite: Remove Content-Length when output filter can
4949 invalidate it. Warn when input filter can invalidate it.
4952 *) Authz: Add the new module mod_authn_core that will provide common
4953 authn directives such as 'AuthType', 'AuthName'. Move the directives
4954 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
4955 into mod_authn_core. [Brad Nicholes]
4957 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
4958 into the new module mod_access_compat which can be loaded to provide
4959 support for these directives.
4962 *) Authz: Move the 'Require' directive from the core module as well as
4963 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
4964 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
4965 logic into the authorization processing. [Brad Nicholes]
4967 *) Authz: Add the new module mod_authz_core which acts as the
4968 authorization provider vector and contains common authz
4969 directives. [Brad Nicholes]
4971 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
4972 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
4974 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
4975 host-based access control provided by mod_authz_host and invoked
4976 through the 'Require' directive. [Brad Nicholes]
4978 *) Authz: Convert all of the authz modules from hook based to
4979 provider based. [Brad Nicholes]
4981 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
4982 seconds to cache a document.
4983 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
4985 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
4987 *) Fix typo in ProxyStatus syntax error message.
4988 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
4990 *) Asynchronous write completion for the Event MPM. [Brian Pane]
4992 *) Added an End-Of-Request bucket type. The logging of a request and
4993 the freeing of its pool are now done when the EOR bucket is destroyed.
4994 This has the effect of delaying the logging until right after the last
4995 of the response is sent; ap_core_output_filter() calls the access logger
4996 indirectly when it destroys the EOR bucket. [Brian Pane]
4998 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
4999 and the format of statistical output has changed. [Colm MacCarthaigh]
5001 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
5003 *) Added new connection states for handler and write completion
5006 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
5009 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
5010 allowing string-valued client certificate attributes to be used for
5011 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
