Changes with Apache 2.4.19
*) mod_log_config: Add GlobalLog to allow a globally defined log to
be inherited by virtual hosts that define a CustomLog.
[Edward Lu]
*) mod_http2: connection how keep a "push diary" where hashes of already
pushed resources are kept. See directive H2PushDiarySize for managing this.
Push diaries can be initialized by clients via the "Cache-Digest" request
header. This carries a base64url encoded. compressed Golomb set as described
in https://datatracker.ietf.org/doc/draft-kazuho-h2-cache-digest/
Introduced a status handler for HTTP/2 connections, giving various counters
and statistics about the current connection, plus its cache digest value
in a JSON record. Not a replacement for more HTTP/2 in the server status.
Configured as
SetHandler http2-status
[Stefan Eissing]
*) mod_http2: Fixed flushing of last GOAWAY frame. Previously, that frame
did not always reach the client, causing some to fail the next request.
Fixed calculation of last stream id accepted as described in rfc7540.
Reading in KEEPALIVE state now correctly shown in scoreboard.
Fixed possible race in connection shutdown after review by Ylavic.
Fixed segfault on connection shutdown, callback ran into a semi dismantled session.
[Stefan Eissing]
*) mod_http2: Added support for experimental accept-push-policy draft
(https://tools.ietf.org/html/draft-ruellan-http-accept-push-policy-00). Clients
may now influence server pushes by sending accept-push-policy headers.
[Stefan Eissing]
*) mod_http2: new r->subprocess_env variables HTTP2 and H2PUSH, set to "on"
when available for request.
[Stefan Eissing]
*) mod_http2: new config directives and the implementation behind
them: H2Timeout, H2KeepAliveTimeout, H2StreamTimeout. Documentation in
the http2 manual.
[Stefan Eissing]
*) mod_http2: fixed bug in input window size calculation by moving chunked
request body encoding into later stage of processing. Fixes PR 58825.
[Stefan Eissing]
Changes with Apache 2.4.18
*) mod_ssl: for all ssl_engine_vars.c lookups, fall back to master connection
if conn_rec itself holds no valid SSLConnRec*. Fixes PR58666.
[Stefan Eissing]
*) mod_http2: connection level window for flow control is set to protocol
maximum of 2GB-1, preventing window exhaustion when sending data on many
streams with higher cumulative window size.
Reducing write frequency unless push promises need to be flushed.
[Stefan Eissing]
*) mod_http2: required minimum version of libnghttp2 is 1.2.1
[Stefan Eissing]
*) mod_proxy_fdpass: Fix AH01153 error when using the default configuration.
In earlier version of httpd, you can explicitelly set the 'flusher' parameter
to 'flush' as a workaround. (i.e. flusher=flush)
Add documentation for the 'flusher' parameter when defining a proxy worker.
[Christophe Jaillet]
*) mod_ssl: For the "SSLStaplingReturnResponderErrors off" case, make sure
to only staple responses with certificate status "good". [Kaspar Brand]
*) mod_http2: new directive 'H2PushPriority' to allow priority specifications
on server pushed streams according to their content-type.
[Stefan Eissing]
*) mod_http2: fixes crash on connection abort for a busy connection.
fixes crash on a request that did not produce any response.
[Stefan Eissing]
*) mod_http2: trailers are sent after reponse body if set in request_rec
trailers_out before the end-of-request bucket is sent through the
output filters. [Stefan Eissing]
*) mod_http2: incoming trailers (headers after request body) are properly
forwarded to the processing engine. [Stefan Eissing]
*) mod_http2: new directive 'H2Push' to en-/disable HTTP/2 server
pushes a server/virtual host. Pushes are initiated by the presence
of 'Link:' headers with relation 'preload' on a response. [Stefan Eissing]
*) mod_http2: write performance of http2 improved for larger resources,
especially static files. [Stefan Eissing]
*) core: if the first HTTP/1.1 request on a connection goes to a server that
prefers different protocols, these protocols are announced in a Upgrade:
header on the response, mentioning the preferred protocols.
[Stefan Eissing]
*) mod_http2: new directives 'H2TLSWarmUpSize' and 'H2TLSCoolDownSecs'
to control TLS record sizes during connection lifetime.
[Stefan Eissing]
*) mod_http2: new directive 'H2ModernTLSOnly' to enforce security
requirements of RFC 7540 on TLS connections. [Stefan Eissing]
*) core: add ap_get_protocol_upgrades() to retrieve the list of protocols
that a client could possibly upgrade to. Use in first request on a
connection to announce protocol choices. [Stefan Eissing]
*) mod_http2: reworked deallocation on connection shutdown and worker
abort. Separate parent pool for all workers. worker threads are joined
on planned worker shutdown. [Yann Ylavic, Stefan Eissing]
*) mod_ssl: when receiving requests for other virtual hosts than the handshake
server, the SSL parameters are checked for equality. With equal
configuration, requests are passed for processing. Any change will trigger
the old behaviour of "421 Misdirected Request".
SSL now remembers the cipher suite that was used for the last handshake.
This is compared against for any vhost/directory cipher specification.
Detailed examination of renegotiation is only done when these do not
match.
Renegotiation is 403ed when a master connection is present. Exact reason
is given additionally in a request note. [Stefan Eissing]
*) mod_ssl: Make the output filter more friendly with deferred write and
response pipelining. [Yann Ylavic, Joe Orton]
*) core: Fix scoreboard crash (SIGBUS) on hardware requiring strict 64bit
alignment (SPARC64, PPC64). [Yann Ylavic]
*) mod_cache: Accept HT (Horizontal Tab) when parsing cache related header
fields as described in RFC7230. [Christophe Jaillet]
*) core/util_script: making REDIRECT_URL a full URL is now opt-in
via new 'QualifyRedirectURL' directive.
*) core: Limit to ten the number of tolerated empty lines between request,
and consume them before the pipelining check to avoid possible response
delay when reading the next request without flushing. [Yann Ylavic]
*) mod_ssl: Extend expression parser registration to support ssl variables
in any expression using mod_rewrite syntax "%{SSL:VARNAME}" or function
syntax "ssl(VARNAME)". [Rainer Jung]
Changes with Apache 2.4.17
*) mod_http2: added donated HTTP/2 implementation via core module. Similar
configuration options to mod_ssl. [Stefan Eissing]
*) mod_proxy: don't recyle backend announced "Connection: close" connections
to avoid reusing it should the close be effective after some new request
is ready to be sent. [Yann Ylavic]
*) mod_substitute: Allow to configure the patterns merge order with the new
SubstituteInheritBefore on|off directive. PR 57641

and change the compiled-in default for SSL[Proxy]Protocol to "all -SSLv3",
in accordance with RFC 7568. PR 58349, PR 57120. [Kaspar Brand]
*) mod_ssl: append :!aNULL:!eNULL:!EXP to the cipher string settings,
instead of prepending !aNULL:!eNULL:!EXP: (as was the case in 2.4.7
and later). Enables support for configuring the SUITEB* cipher
strings introduced in OpenSSL 1.0.2. PR 58213. [Kaspar Brand]
*) mod_ssl: Add support for extracting the msUPN and dnsSRV forms
of subjectAltName entries of type "otherName" into
SSL_{CLIENT,SERVER}_SAN_OTHER_{msUPN,dnsSRV}_n environment
variables. Addresses PR 58020. [Jan Pazdziora ,
Kaspar Brand]
*) mod_logio: Fix logging of %^FB (time to first byte) on the first request on
an SSL connection. PR 58454.
[Konstantin J. Chernov ]
*) mod_cache: r->err_headers_out is not merged into
r->headers when mod_cache is enabled and the response
is cached for the first time. [Edward Lu]
*) mod_slotmem_shm: Fix slots/SHM files names on restart for systems that
can't create new (clear) slots while previous children gracefully stopping
still use the old ones (e.g. Windows, OS2). mod_proxy_balancer failed to
restart whenever the number of configured balancers/members changed during
restart. PR 58024. [Yann Ylavic]
*) core/util_script: make REDIRECT_URL a full URL. PR 57785. [Nick Kew]
*) MPMs: Support SO_REUSEPORT to create multiple duplicated listener
records for scalability. [Yingqi Lu ,
Jeff Trawick, Jim Jagielski, Yann Ylavic]

PR 57868. [Jose Kahan , Yann Ylavic]
*) mod_socache_memcache: Add the 'MemcacheConnTTL' directive to control how
long to keep idle connections with the memcache server(s).
Change default value from 600 usec (!) to 15 sec. PR 58091
[Christophe Jaillet]
*) mod_dir: Prevent the internal identifier "httpd/unix-directory" from
appearing as a Content-Type response header when requests for a directory
are rewritten by mod_rewrite. [Eric Covener]
Changes with Apache 2.4.16
*) http: Fix LimitRequestBody checks when there is no more bytes to read.
[Michael Kaufmann ]
*) mod_alias: Revert expression parser support for Alias, ScriptAlias
and Redirect due to a regression (introduced in 2.4.13, not released).

*) Fix startup segfault when the Mutex directive is used but no loaded
modules use httpd mutexes. PR 48787. [Jeff Trawick]
*) Proxy: get the headers right in a HEAD request with
ProxyErrorOverride, by checking for an overridden error
before not after going into a catch-all code path.
PR 41646. [Nick Kew, Stuart Children]
*) support/rotatelogs: Support the simplest log rotation case, log
truncation. Useful when the log is being processed in real time
using a command like tail. [Graham Leggett]
*) support/htcacheclean: Teach it how to write a pid file (modelled on
httpd's writing of a pid file) so that it becomes possible to run
more than one instance of htcacheclean on the same machine.
[Graham Leggett]
*) Log command line on startup, so there's a record of command line
arguments like -f. PR 48752. [Dan Poirier]
*) Introduce mod_reflector, a handler capable of reflecting POSTed
request bodies back within the response through the output filter
stack. Can be used to turn an output filter into a web service.
[Graham Leggett]
*) mod_proxy_http: Make sure that when an ErrorDocument is served
from a reverse proxied URL, that the subrequest respects the status
of the original request. This brings the behaviour of proxy_handler
in line with default_handler. PR 47106. [Graham Leggett]
*) Support wildcards in both the directory and file components of
the path specified by the Include directive. [Graham Leggett]
*) mod_proxy, mod_proxy_http: Support remote https proxies
by using HTTP CONNECT. PR 19188.
[Philippe Dutrueux , Rainer Jung]

Add message when server gets within MinSpareThreads of MaxClients.
PR 46996. [Dan Poirier]
*) mod_session: Session expiry was being initialised, but not updated
on each session save, resulting in timed out sessions when there
should not have been. Fixed. [Graham Leggett]
*) mod_log_config: Add the R option to log the handler used within the
request. [Christian Folini ]
*) mod_include: Allow fine control over the removal of Last-Modified and
ETag headers within the INCLUDES filter, making it possible to cache
responses if desired. Fix the default value of the SSIAccessEnable
directive. [Graham Leggett]
*) Add new UnDefine directive to undefine a variable. PR 35350.
[Stefan Fritsch]
*) Make ap_pregsub(), used by AliasMatch and friends, use the same syntax
for regex backreferences as mod_rewrite and mod_include: Remove the use
of '&' as an alias for '$0' and allow to escape any character with a
backslash. PR 48351. [Stefan Fritsch]
*) mod_authnz_ldap: If AuthLDAPCharsetConfig is set, also convert the
password to UTF-8. PR 45318.
[Johannes Müller , Stefan Fritsch]
*) ab: Fix calculation of requests per second in HTML output. PR 48594.
[Stefan Fritsch]
*) mod_authnz_ldap: Failures to map a username to a DN, or to check a user
password now result in an informational level log entry instead of
warning level. [Eric Covener]
Changes with Apache 2.3.5
*) SECURITY: CVE-2010-0434 (cve.mitre.org)
Ensure each subrequest has a shallow copy of headers_in so that the
parent request headers are not corrupted. Eliminates a problematic
optimization in the case of no request body. PR 48359
[Jake Scott, William Rowe, Ruediger Pluem]
*) Turn static function get_server_name_for_url() into public
ap_get_server_name_for_url() and use it where appropriate. This
fixes mod_rewrite generating invalid URLs for redirects to IPv6
literal addresses. [Stefan Fritsch]
*) mod_ldap: Introduce new config option LDAPTimeout to set the timeout
for LDAP operations like bind and search. [Stefan Fritsch]
*) mod_proxy, mod_proxy_ftp: Move ProxyFtpDirCharset from mod_proxy to
mod_proxy_ftp. [Takashi Sato]
*) mod_proxy, mod_proxy_connect: Move AllowCONNECT from mod_proxy to
mod_proxy_connect. [Takashi Sato]
*) mod_cache: Do an exact match of the keys defined by
CacheIgnoreURLSessionIdentifiers against the querystring instead of
a partial match. PR 48401.
[Dodou Wang , Ruediger Pluem]
*) mod_proxy_balancer: Fix crash in balancer-manager. [Rainer Jung]
*) Core HTTP: disable keepalive when the Client has sent
Expect: 100-continue
but we respond directly with a non-100 response.
Keepalive here led to data from clients continuing being treated as
a new request.
PR 47087 [Nick Kew]
*) Core: reject NULLs in request line or request headers.
PR 43039 [Nick Kew]
*) Core: (re)-introduce -T commandline option to suppress documentroot
check at startup.
PR 41887 [Jan van den Berg ]
*) mod_autoindex: support XHTML as equivalent to HTML in IndexOptions,
ScanHTMLTitles, ReadmeName, HeaderName
PR 48416 [Dmitry Bakshaev , Nick Kew]
*) Proxy: Fix ProxyPassReverse with relative URL
Derived (slightly erroneously) from PR 38864 [Nick Kew]

PR 48422 [Cyril Bonté , Nick Kew>]
*) mod_headers: Enable multi-match-and-replace edit option
PR 46594 [Nick Kew]
*) mod_filter: enable it to act on non-200 responses.
PR 48377 [Nick Kew]
Changes with Apache 2.3.4
*) Replace AcceptMutex, LockFile, RewriteLock, SSLMutex, SSLStaplingMutex,
and WatchdogMutexPath with a single Mutex directive. Add APIs to
simplify setup and user customization of APR proc and global mutexes.
(See util_mutex.h.) Build-time setting DEFAULT_LOCKFILE is no longer
respected; set DEFAULT_REL_RUNTIMEDIR instead. [Jeff Trawick]
*) http_core: KeepAlive no longer accepts other than On|Off.
[Takashi Sato]
*) mod_dav: Remove errno from dav_error interface. Calls to dav_new_error()
and dav_new_error_tag() must be adjusted to add an apr_status_t parameter.
[Jeff Trawick]
*) mod_authnz_ldap: Add AuthLDAPBindAuthoritative to allow Authentication to
try other providers in the case of an LDAP bind failure.
PR 46608 [Justin Erenkrantz, Joe Schaefer, Tony Stevenson]
*) Build: fix --with-module to work as documented
PR 43881 [Gez Saunders ]

mod_proxy_ftp: NULL pointer dereference on error paths.
[Stefan Fritsch , Joe Orton]
*) mod_ssl: enable support for ECC keys and ECDH ciphers. Tested against
OpenSSL 1.0.0b3. [Vipul Gupta , Sander Temme]
*) mod_dav: Include uri when logging a PUT error due to connection abort.
PR 38149. [Stefan Fritsch]
*) mod_dav: Return 409 instead of 500 for a LOCK request if the parent
resource does not exist or is not a collection. PR 43465. [Stefan Fritsch]
*) mod_dav_fs: Return 409 instead of 500 for Litmus test case copy_nodestcoll
(a COPY request where the parent of the destination resource does not
exist). PR 39299. [Stefan Fritsch]
*) mod_dav_fs: Don't delete the whole file if a PUT with content-range failed.
PR 42896. [Stefan Fritsch]
*) mod_dav_fs: Make PUT create files atomically and no longer destroy the
old file if the transfer aborted. PR 39815. [Paul Querna, Stefan Fritsch]
*) mod_dav_fs: Remove inode keyed locking as this conflicts with atomically
creating files. On systems with inode numbers, this is a format change of
the DavLockDB. The old DavLockDB must be deleted on upgrade.
[Stefan Fritsch]
*) mod_log_config: Make ${cookie}C correctly match whole cookie names
instead of substrings. PR 28037. [Dan Franklin ,
Stefan Fritsch]
*) vhost: A purely-numeric Host: header should not be treated as a port.
PR 44979 [Nick Kew]
*) mod_ldap: Avoid 500 errors with "Unable to set LDAP_OPT_REFHOPLIMIT option to 5"
when built against openldap by using SDK LDAP_OPT_REFHOPLIMIT defaults unless
LDAPReferralHopLimit is explicitly configured.
[Eric Covener]
*) mod_charset_lite: Honor 'CharsetOptions NoImplicitAdd'.
[Eric Covener]
*) mod_ssl: Add support for OCSP Stapling. PR 43822.
