Changes with Apache 2.4.36

  *) mod_proxy_scgi, mod_proxy_uwsgi: improve error handling when sending the
     body of the response. [Jim Jagielski]

  *) mod_http2: adding defensive code for stream EOS handling, in case the request handler
     missed to signal it the normal way (eos buckets). Addresses github issues 
     https://github.com/icing/mod_h2/issues/164, https://github.com/icing/mod_h2/issues/167
     and https://github.com/icing/mod_h2/issues/170. [Stefan Eissing] 

  *) ab: Add client certificate support. [Graham Leggett]

  *) ab: Disable printing temp key for OpenSSL before
     version 1.0.2. SSL_get_server_tmp_key is not available
     there. [Rainer Jung]

  *) mod_ssl: Fix a regression that the configuration settings for verify mode
     and verify depth were taken from the frontend connection in case of
     connections by the proxy to the backend. PR 62769. [Ruediger Pluem]

  *) MPMs: Initialize all runtime/asynchronous objects on a dedicated pool and
     before signals handling to avoid lifetime issues on restart or shutdown.
     PR 62658. [Yann Ylavic]

  *) mod_ssl: Add support for OpenSSL 1.1.1 and TLSv1.3.  TLSv1.3 has
     behavioural changes compared to v1.2 and earlier; client and
     configuration changes should be expected.  SSLCipherSuite is
     enhanced for TLSv1.3 ciphers, but applies at vhost level only.
     [Stefan Eissing, Yann Ylavic, Ruediger Pluem, Joe Orton]
  *) mod_auth_basic: Be less tolerant when parsing the credencial. Only spaces
     should be accepted after the authorization scheme. \t are also tolerated.
     [Christophe Jaillet]

  *) mod_proxy_hcheck: Fix issues with interval determination. PR 62318
     [Jim Jagielski]

  *) mod_proxy_hcheck: Fix issues with TCP health checks. PR 61499
     [Dominik Stillhard <dominik.stillhard united-security-providers.ch>]

  *) mod_proxy_hcheck: take balancer's SSLProxy* directives into account.
     [Jim Jagielski]

  *) mod_status, mod_echo: Fix the display of client addresses.
    They were truncated to 31 characters which is not enough for IPv6 addresses.
    This is done by deprecating the use of the 'client' field and using
    the new 'client64' field in worker_score.
    PR 54848 [Bernhard Schmidt <berni birkenwald de>, Jim Jagielski]

  *) http: Enforce consistently no response body with both 204 and 304
     statuses.  [Yann Ylavic]

  *) mod_status: Cumulate CPU time of exited child processes in the
     "cu" and "cs" values. Add CPU time of the parent process to the
     "c" and "s" values.
     [Rainer Jung]

  *) mod_proxy: Improve the balancer member data shown in mod_status when
     "ProxyStatus" is "On": add "busy" count and show byte counts in
     auto mode always in units of kilobytes.  [Rainer Jung]
  *) mod_status: Add cumulated response duration time in milliseconds.
  *) mod_status: Complete the data shown for async MPMs in "auto" mode.
     Added number of processes, number of stopping processes and number
     of busy and idle workers.  [Rainer Jung]

  *) mod_ratelimit: Don't interfere with "chunked" encoding, fixing regression
     introduced in 2.4.34.  PR 62568.  [Yann Ylavic]

  *) mod_proxy: Remove load order and link dependency between mod_lbmethod_*
     modules and mod_proxy. PR 62557. [Ruediger Pluem, William Rowe]

  *) Allow the argument to <IfFile>, <IfDefine>, <IfSection>, <IfDirective>,
Eric Covener's avatar

     and <IfModule> to be quoted.  This is primarily for the benefit of
     <IfFile>. [Eric Covener]

  *) mod_watchdog: Correct some log messages.  [Rainer Jung]

  *) core: Re-allow '_' (underscore) in hostnames.
     [Eric Covener]

  *) mod_authz_core: If several parameters are used in a AuthzProviderAlias
     directive, if these parameters are not enclosed in quotation mark, only
     the first one is handled. The other ones are silently ignored.
     Add a message to warn about such a spurious configuration.

  *) mod_md: improvements and bugfixes
     - MDNotifyCmd now takes additional parameter that are passed on to the called command.
     - ACME challenges have better checks for interference with other modules
     - ACME challenges are only handled for domains managed by the module, allowing
       other ACME clients to operate for other domains in the server.
     - better libressl integration

  *) mod_proxy_wstunnel: Add default schema ports for 'ws' and 'wss'.
     PR 62480. [Lubos Uhliarik <luhliari redhat.com>}

  *) logging: Some early logging-related startup messages could be lost
     when using syslog for the global ErrorLog. [Eric Covener]

  *) mod_cache: Handle case of an invalid Expires header value RFC compliant
     like the case of an Expires time in the past: allow to overwrite the
     non-caching decision using CacheStoreExpired and respect Cache-Control
     "max-age" and "s-maxage".  [Rainer Jung]

  *) mod_xml2enc: Fix forwarding of error metadata/responses. PR 62180.
     [Micha Lenk <micha lenk.info>, Yann Ylavic]

  *) mod_proxy_http: Fix response header thrown away after the previous one
     was considered too large and truncated. PR 62196. [Yann Ylavic]

     of functions to consume the end of line when the buffer is exhausted.

  *) mod_ssl: Extend SSLOCSPEnable with mode 'leaf' that only checks the leaf
     of a certificate chain.  PR62112.
     [Ricardo Martin Camarero <rickyepoderi yahoo.es>]

  *) http: Fix small memory leak per request when handling persistent
     connections.  [Ruediger Pluem, Joe Orton]

  *) mod_remoteip: When overriding the useragent address from X-Forwarded-For,
     zero out what had been initialized as the connection-level port.  PR59931.

  *) core: In ONE_PROCESS/debug mode, cleanup everything when exiting.
     [Yann Ylavic]

  *) mod_proxy_balancer: Add hot spare member type and corresponding flag (R).
     Hot spare members are used as drop-in replacements for unusable workers
     in the same load balancer set. This differs from hot standbys which are
     only used when all workers in a set are unusable. PR 61140. [Jim Riggs]

  *) suexec: Add --enable-suexec-capabilites support on Linux, to use
     setuid/setgid capability bits rather than a setuid root binary.
     [Joe Orton]

  *) suexec: Add support for logging to syslog as an alternative to
     logging to a file; use --without-suexec-logfile --with-suexec-syslog.
