calls r:wsupgrade() can cause a child process crash.
[Edward Lu <Chaosed0 gmail.com>]
*) mod_ssl OCSP Stapling: Don't block initial handshakes while refreshing
the OCSP response for a different certificate. mod_ssl has an additional
global mutex, "ssl-stapling-refresh". PR 57131 (partial fix).

*) mod_authz_dbm: Fix crashes when "dbm-file-group" is used and
authz modules were loaded in the "wrong" order. [Joe Orton]
*) mod_authn_dbd, mod_authz_dbd, mod_session_dbd, mod_rewrite: Fix lifetime
of DB lookup entries independently of the selected DB engine. PR 46421.

*) In alignment with RFC 7525, the default recommended SSLCipherSuite
and SSLProxyCipherSuite now exclude RC4 as well as MD5. Also, the
default recommended SSLProtocol and SSLProxyProtocol directives now
exclude SSLv3. Existing configurations must be adjusted by the
*) mod_ssl: Add support for extracting subjectAltName entries of type
rfc822Name and dNSName into SSL_{CLIENT,SERVER}_SAN_{Email,DNS}_n

no If headers providing them on a resource we aren't modifying.
[Ben Reser]
*) mod_proxy_scgi: ProxySCGIInternalRedirect now allows an alternate
response header to be used by the application, for when the application
or framework is unable to return Location in the internal-redirect
form. [Jeff Trawick]
*) core: Cleanup the request soon/even if some output filter fails to
handle the EOR bucket. [Yann Ylavic]
*) mpm_event: Allow for timer events duplicates. [Jim Jagielski, Yann Ylavic]
*) mod_proxy, mod_ssl, mod_cache_socache, mod_socache_*: Support machine
readable server-status produced when using the "?auto" query string.
[Rainer Jung]
*) mod_status: Add more data to machine readable server-status produced
when using the "?auto" query string. [Rainer Jung]
*) mod_ssl: Check for the Entropy Gathering Daemon (EGD) availability at
configure time (RAND_egd), and complain if SSLRandomSeed requires using
it otherwise. [Bernard Spil <pil.oss gmail com>, Stefan Sperling,
Kaspar Brand]
*) mod_ssl: make sure to consistently output SSLCertificateChainFile
deprecation warnings, when encountered in a VirtualHost block.
[Falco Schwarz <hiding falco.me>]
*) mod_log_config: Add "%{UNIT}T" format to output request duration in
seconds, milliseconds or microseconds depending on UNIT ("s", "ms", "us").
[Ben Reser, Rainer Jung]
*) Allow FallbackResource to work when a directory is requested and
there is no autoindex nor DirectoryIndex.
[Jack <tjerk.meesters gmail.com>, Eric Covener]
*) mod_proxy_wstunnel: Bypass the handler while the connection is not
upgraded to WebSocket, so that other modules can possibly take over
the leading HTTP requests. [Yann Ylavic]
*) mod_http: Fix incorrect If-Match handling. PR 57358
[Kunihiko Sakamoto <ksakamoto google.com>]
*) mod_ssl: Add a warning if protocol given in SSLProtocol or SSLProxyProtocol
will override other parameters given in the same directive. This could be
a missing + or - prefix. PR 52820 [Christophe Jaillet]
*) mod_proxy: Use the correct server name for SNI in case the backend
SSL connection itself is established via a proxy server.
PR 57139 [Szabolcs Gyurko <szabolcs gyurko.org>]
*) mod_ssl: Fix possible crash when loading server certificate constraints.
PR 57694. [Paul Spangler <paul.spangler ni com>, Yann Ylavic]
*) build: Don't load both mod_cgi and mod_cgid in the default configuration
if they're both built. [olli hauer <ohauer gmx.de>]
*) mod_logio: Add LogIOTrackTTFB and %^FB logformat to log the time
taken to start writing response headers. [Eric Covener]
*) mod_ssl: Avoid compilation errors with LibreSSL related to
the use of ENGINE_CTRL_CHIL_SET_FORKCHECK.
[Stuart Henderson <sthen openbsd.org>]
*) mod_proxy_http: Use the "Connection: close" header for requests to
backends not recycling connections (disablereuse), including the default
reverse and forward proxies. [Yann Ylavic]
*) mod_proxy: Add ap_connection_reusable() for checking if a connection
is reusable as of this point in processing. [Jeff Trawick]
*) mod_proxy_wstunnel: Avoid an empty response by failing with 502 (Bad
Gateway) when no response is ever received from the backend.

access to freed memory. [Yann Ylavic, Christophe Jaillet]
*) core: Add CGIPassAuth directive to control whether HTTP authorization
headers are passed to scripts as CGI variables. PR 56855. [Jeff
Trawick]
*) core: Initialize scoreboard's used optional functions on graceful restarts
to avoid a crash when relocation occurs. PR 57177. [Yann Ylavic]
*) mod_dav: Avoid a potential integer underflow in the lock timeout value sent
back to a client. The answer to a LOCK request could be an extremly large
integer if the time needed to lock the resource was longer that the
requested timeout given in the LOCK request. In such a case, we now answer
"Second-0". PR55420
[Christophe Jaillet]
*) mod_cgid: Within the first minute of a server start or restart,
allow mod_cgid to retry connecting to its daemon process. Previously,
'No such file or directory: unable to connect to cgi daemon...' could
be logged without an actual retry. PR57685.
[Edward Lu <Chaosed0 gmail.com>]
*) mod_proxy: Use the original (non absolute) form of the request-line's URI
for requests embedded in CONNECT payloads used to connect SSL backends via
a ProxyRemote forward-proxy. PR 55892. [Hendrik Harms <hendrik.harms
gmail com>, William Rowe, Yann Ylavic]
*) http: Make ap_die() robust against any HTTP error code and not modify
response status (finally logged) when nothing is to be done. [Yann Ylavic]
*) mod_proxy_connect/wstunnel: If both client and backend sides get readable
at the same time, don't lose errors occuring while forwarding on the first
side when none occurs next on the other side, and abort. [Yann Ylavic]
*) mod_rewrite: Improve relative substitutions in per-directory/htaccess
context for directories found by mod_userdir and mod_alias. These no
longer require RewriteBase to be specified. [Eric Covener]
*) mod_proxy_http: Don't expect the backend to ack the "Connection: close" to
finally close those not meant to be kept alive by SetEnv proxy-nokeepalive
or force-proxy-request-1.0. [Yann Ylavic]
*) core: If explicitly configured, use the KeepaliveTimeout value of the
virtual host which handled the latest request on the connection, or by
default the one of the first virtual host bound to the same IP:port.
PR56226. [Yann Ylavic]
*) mod_lua: After a r:wsupgrade(), mod_lua was not properly
responding to a websockets PING but instead invoking the specified
script. PR57524. [Edward Lu <Chaosed0 gmail.com>]
*) mod_ssl: Add the SSL_CLIENT_CERT_RFC4523_CEA variable, which provides
a combination of certificate serialNumber and issuer as defined by
CertificateExactMatch in RFC4523. [Graham Leggett]
*) core: Add expression support to ErrorDocument. Switch from a fixed
sized 664 byte array per merge to a hash table. [Graham Leggett]
