discourage content encoders on http2-status response (where they do not work).

shortage. PR 61979. [Yann Ylavic]

with an OpenSSL build which does not support any compression methods.

implementing the Let's Encrypt ACMEv1 protocol to signup and renew
certificates. Please read the modules documentation for further instructions
on how to use it. [Stefan Eissing]

*) mpm_event: close connections not reported as handled by any module to
avoid losing track of them and leaking scoreboard entries. PR 61551.
[Yann Ylavic]

process. PR 61558. [Yann Ylavic]

*) mod_rewrite, core: add the Vary header when a condition evaluates to true
and the related RewriteRule is used in a Directory context
(triggering an internal redirect). [Luca Toscano]
*) ab: Make the TLS layer aware that the underlying socket is nonblocking,
and use/handle POLLOUT where needed to avoid busy IOs and recover write
errors when appropriate. [Yann Ylavic]
*) ab: Keep reading nonblocking to exhaust TCP or SSL buffers when previous
read was incomplete (the SSL case can cause the next poll() to timeout
since data are buffered already). PR 61301 [Luca Toscano, Yann Ylavic]
*) mod_http2: avoid unnecessary data retrieval for a trace log. Allow certain
information retrievals on null bucket beams where it makes sense. [Stefan Eissing]
*) mod_unique_id: Use output of the PRNG rather than IP address and
pid, avoiding sleep() call and possible DNS issues at startup,
plus improving randomness for IPv6-only hosts. [Jan Kaluza]

is used in a condition that evaluates to true. PR 58231 [Luca Toscano, Yann Ylavic]

consumption. Chunked responses will be generated in more cases

*) mod_proxy: Fix ProxyAddHeaders merging. [Joe Orton]
*) core: Disallow multiple Listen on the same IP:port when listener buckets
are configured (ListenCoresBucketsRatio > 0), consistently with the single
bucket case (default), thus avoiding the leak of the corresponding socket
descriptors on graceful restart. [Yann Ylavic]

*) SECURITY: CVE-2017-9789 (cve.mitre.org)

freed, resulting in potentially erratic behaviour.

in [Proxy-]Authorization headers type 'Digest' was not initialized or
reset before or between successive key=value assignments.
*) COMPATIBILITY: mod_lua: Remove the undocumented exported 'apr_table'
global variable when using Lua 5.2 or later. This was exported as a
side effect from luaL_register, which is no longer supported as of
