*) mod_dir: Responses that go through "FallbackResource" might appear to
hang due to unterminated chunked encoding. PR58292. [Eric Covener]

*) http: Add support for RFC2324/RFC7168. [Graham Leggett]
*) mod_rewrite: Add support for starting External Rewriting Programs
as non-root user on UNIX systems by specifying username and group name
as third argument of RewriteMap directive. [Jan Kaluza]
*) mod_authn_core: Add expression support to AuthName and AuthType.
[Graham Leggett]
*) suexec: Filter out the HTTP_PROXY environment variable because it is
treated as alias for http_proxy by some programs. [Stefan Fritsch]
*) mod_proxy_http: Don't establish or reuse a backend connection before pre-
fetching the request body, so to minimize the delay between it is supposed
to be alive and the first bytes sent: this is a best effort to prevent the
backend from closing because of idle or keepalive timeout in the meantime.
Also, handle a new "proxy-flushall" environment variable which allows to
flush any forwarded body data immediately. PR 56541+37920. [Yann Ylavic]
*) core: Define and UnDefine are no longer permitted in

*) mod_authnz_ldap: Resolve crashes with LDAP authz and non-LDAP authn since
r1608202. [Eric Covener]
*) apreq: Content-Length header should be always interpreted as a decimal.
Leading 0 could be erroneously considered as an octal value. PR 56598.
[Chris Card <ctcard hotmail com>]
*) mod_proxy: Now allow for 191 character worker names, with non-fatal
errors if name is truncated. PR53218. [Jim Jagielski]
*) mod_ssl: Add optional function "ssl_get_tls_cb" to allow support
for channel bindings. [Simo Sorce <simo redhat.com>]
*) mod_proxy_wstunnel: Concurrent websockets messages could be
lost or delayed with ProxyWebsocketAsync enabled.

processing mode. [Eric Covener]
*) mod_authnz_ldap: Fail explicitly when the filter is too long. Remove
unnecessary apr_pstrdup() and strlen(). [Graham Leggett]
*) Add the ldap-search option to mod_authnz_ldap, allowing authorization
to be based on arbitrary expressions that do not include the username.
[Graham Leggett]
*) Add the ldap function to the expression API, allowing LDAP filters and
distinguished names based on expressions to be escaped correctly to
guard against LDAP injection. [Graham Leggett]
*) Add module mod_ssl_ct, which provides an implementation of Certificate
Transparency (RFC 6962) for httpd. [Jeff Trawick]
*) mod_proxy_wstunnel: Avoid sending error responses down an upgraded
websockets connection as it is being close down. [Eric Covener]
*) mod_proxy_wstunnel: Allow the administrator to cap the amount
of time a synchronous websockets connection stays idle with
ProxyWebsocketIdleTimeout. [Eric Covener]

allow spaces in backreferences to be encoded as %20 instead of '+'.
[Eric Covener]
*) mod_rewrite: Support an optional list of characters to escape in the
argument for the 'B' (escape backreferences) flag. [Eric Covener]
*) mod_dir: Default to 2.2-like behavior and skip execution when method is
neither GET nor POST, such as for DAV requests. PR 54914. [Chris Darroch]
*) mod_rewrite: Rename the handler that does per-directory internal
redirects to "rewrite-redirect-handler" from "redirect-handler" so
it is less ambiguous and less likely to be reused. [Eric Covener]
*) mod_rewrite: Protect against looping with the [N] flag by enforcing a
default limit of 10000 iterations, and allowing each rule to change its
limit. [Eric Covener]
*) mod_ssl: Fix config merging of SSLOCSPEnable and SSLOCSPOverrideResponder.
[Jeff Trawick]
*) Add HttpContentLengthHeadZero and HttpExpectStrict directives.
[Yehuda Sadeh <yehuda inktank com>, Justin Erenkrantz]

[Jan Kaluza]
*) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
syslog support from core to new mod_syslog. [Jan Kaluza]
*) mod_status, mod_echo: Fix the display of client addresses.
They were truncated to 31 characters which is not enough for IPv6 addresses.
PR 54848 [Bernhard Schmidt <berni birkenwald de>]
*) 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 <jkaluza redhat.com>]
*) mod_file_cache: mod_file_cache should be able to serve files that
haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]

not only when AuthName is used in .htaccess files (this change may cause
problems if used with round robin load balancers). Don't regenerate the
secret on graceful restarts. PR 54637 [Stefan Fritsch]
*) core: Remove apr_brigade_flatten(), buffering and duplicated code
from the HTTP_IN filter, parse chunks in a single pass with zero copy.
Reduce memory usage by 48 bytes per request. [Graham Leggett]
*) core: Stop the HTTP_IN filter from attempting to write error buckets
to the output filters, which is bogus in the proxy case. Create a
clean mapping from APR codes to HTTP status codes, and use it where
needed. [Graham Leggett]
*) mod_proxy: Ensure network errors detected by the proxy are returned as
504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
*) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
[Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
<alejandro.alvarez.ayllon cern.ch>]
*) mod_ldap: LDAP connections used for authentication were not respecting
LDAPConnectionPoolTimeout. PR 54587
*) core: ap_rgetline_core now pulls from r->proto_input_filters.
*) mod_proxy_html: process parsed comments immediately.
Fixes bug where parsed comments may be lost. [Nick Kew]

warnings in mod_ssl. [Stefan Fritsch]
*) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
Cache the result of the most recent password hash verification for every
keep-alive connection. This saves some expensive calculations.
[Stefan Fritsch]
*) http: Remove support for Request-Range header sent by Navigator 2-3 and
MSIE 3. [Stefan Fritsch]
*) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
conformance or to only log the found problems. [Stefan Fritsch]
*) core: Correctly parse an IPv6 literal host specification in an absolute
URL in the request line. [Stefan Fritsch]
*) EventOpt MPM
*) core: Add LogLevelOverride directive that allows to override the
loglevel for clients from certain IPs. This also works for things
like the SSL handshake where <If> LogLevel ... </If> is evaluated
too late. [Stefan Fritsch]
*) core: Add new directive Warning to issue warnings from a configuration
file. Both Warning and Error now generate a timestamped log message.
[Fabien Coelho]

to allow tracking of threads from exiting children via mod_status
or other such mechanisms. [Jeff Trawick]
*) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
- APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
- mod_cache: thundering herd lock directory
- mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
- mod_ldap: shared memory cache
- mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
[Jeff Trawick]
*) 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; configure --without-suexec-logfile --with-suexec-syslog.
[Joe Orton]
*) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
[Matthew Steele <mdsteele google.com>]
*) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
be compiled by the build compiler instead of the host compiler.
Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
