25 neither GET nor POST, such as for DAV requests. PR 54914. [Chris Darroch]
27 *) mod_rewrite: Rename the handler that does per-directory internal
28 redirects to "rewrite-redirect-handler" from "redirect-handler" so
29 it is less ambiguous and less likely to be reused. [Eric Covener]
31 *) mod_dir: Add DirectoryCheckHandler to allow a 2.2-like behavior, skipping
32 execution when a handler is already set. PR53929. [Eric Covener]
34 *) mod_rewrite: Protect against looping with the [N] flag by enforcing a
35 default limit of 10000 iterations, and allowing each rule to change its

52 *) FreeBSD: Disable IPv4-mapped listening sockets by default for versions
53 5+ instead of just for FreeBSD 5. PR 53824. [Jeff Trawick]
55 *) mod_auth_form: Add a debug message when the fields on a form are not
56 recognised. [Graham Leggett]

97 the AuthFormProvider isn't specified. [Graham Leggett]
99 *) mod_lua: Let the Inter-VM get/set functions work with a global

109 to avoid performance problems when subgroups aren't in use. [Eric Covener]
111 *) mod_syslog: New module implementing syslog ap_error_log provider.
112 Previously, this code was part of core, now it's in separate module.
115 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
116 syslog support from core to new mod_syslog. [Jan Kaluza]
118 *) core: draft-ietf-httpbis-p1-messaging-23 corrections regarding
119 TE/CL conflicts. [Yann Ylavic <ylavic.dev gmail com>, Jim Jagielski]
121 *) WinNT MPM: If ap_run_pre_connection() fails or sets c->aborted, don't
122 save the socket for reuse by the next worker as if it were an
123 APR_SO_DISCONNECTED socket. Restores 2.2 behavior. [Eric Covener]
125 *) mod_lua: Add a logging hook for modifying/skipping logs. [Daniel Gruno]
127 *) mod_status, mod_echo: Fix the display of client addresses.
128 They were truncated to 31 characters which is not enough for IPv6 addresses.
129 PR 54848 [Bernhard Schmidt <berni birkenwald de>]
131 *) mod_authnz_fcgi: New module to enable FastCGI authorizer
132 applications to authenticate and/or authorize clients.
135 *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers.
138 *) mod_unique_id: Use output of the PRNG rather than IP address and
139 pid, avoiding sleep() call and possible DNS issues at startup,

141 [Jan Kaluza <jkaluza redhat.com>]
143 *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
144 filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special
145 filter "none" to be specified in AuthLDAPURL. [Eric Covener]
147 *) mod_file_cache: mod_file_cache should be able to serve files that
148 haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]
150 *) core: merge AllowEncodedSlashes from the base configuration into
151 virtual hosts. [Eric Covener]
153 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
156 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.

160 been configured with -D Z_PREFIX, which redefines the token "deflate".
163 *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
164 previously limited to 64MB. [Jens Låås <jelaas gmail.com>]
166 *) mod_auth_digest: Use the secret when generating nonces in all cases and
167 not only when AuthName is used in .htaccess files (this change may cause
168 problems if used with round robin load balancers). Don't regenerate the
169 secret on graceful restarts. PR 54637 [Stefan Fritsch]
171 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
172 from the HTTP_IN filter, parse chunks in a single pass with zero copy.
173 Reduce memory usage by 48 bytes per request. [Graham Leggett]
175 *) core: Stop the HTTP_IN filter from attempting to write error buckets
176 to the output filters, which is bogus in the proxy case. Create a
177 clean mapping from APR codes to HTTP status codes, and use it where
178 needed. [Graham Leggett]
180 *) mod_proxy: Ensure network errors detected by the proxy are returned as
181 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
182 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
184 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
185 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
186 <alejandro.alvarez.ayllon cern.ch>]
188 *) core, mod_ssl: Enable the ability for a module to reverse the sense of
189 a poll event from a read to a write or vice versa. This is a step on
190 the way to allow mod_ssl taking full advantage of the event MPM.
193 *) mod_ldap: LDAP connections used for authentication were not respecting
194 LDAPConnectionPoolTimeout. PR 54587
196 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
198 *) mod_proxy_html: process parsed comments immediately.
199 Fixes bug where parsed comments may be lost. [Nick Kew]
201 *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew]
203 *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional"
204 HTML/XHTML [Nick Kew]
206 *) core: Add option to add valgrind support. Use it to reduce false positive
207 warnings in mod_ssl. [Stefan Fritsch]
209 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
210 Cache the result of the most recent password hash verification for every
211 keep-alive connection. This saves some expensive calculations.
214 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
215 MSIE 3. [Stefan Fritsch]
217 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
218 conformance or to only log the found problems. [Stefan Fritsch]
220 *) core: Correctly parse an IPv6 literal host specification in an absolute
221 URL in the request line. [Stefan Fritsch]
225 *) core: Add LogLevelOverride directive that allows to override the
226 loglevel for clients from certain IPs. This also works for things
227 like the SSL handshake where <If> LogLevel ... </If> is evaluated
228 too late. [Stefan Fritsch]
230 *) core: Add new directive Warning to issue warnings from a configuration
231 file. Both Warning and Error now generate a timestamped log message.
234 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
235 variables. [Stefan Fritsch]
237 *) core: New directive RegisterHttpMethod for registering non-standard
238 HTTP methods. [Stefan Fritsch]
240 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
241 support. [Stefan Fritsch]
243 *) mod_allowhandlers: New module to forbid specific handlers for specific
244 directories. [Stefan Fritsch]
246 *) mod_systemd: New module, for integration with systemd on Linux.
247 [Jan Kaluza <jkaluza redhat.com>]
249 *) WinNT MPM: Store pid and generation for each thread in scoreboard
250 to allow tracking of threads from exiting children via mod_status
251 or other such mechanisms. [Jeff Trawick]
253 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
254 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
255 - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
257 - mod_cache: thundering herd lock directory
258 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
259 - mod_ldap: shared memory cache
260 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
263 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
264 setuid/setgid capability bits rather than a setuid root binary.
267 *) suexec: Add support for logging to syslog as an alternative to logging
268 to a file; configure --without-suexec-logfile --with-suexec-syslog.
271 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
272 [Matthew Steele <mdsteele google.com>]
274 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
275 be compiled by the build compiler instead of the host compiler.
276 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
277 PR 51257. [Guenter Knauf]
279 *) core: In maintainer mode, replace apr_palloc with a version that
280 initializes the allocated memory with non-zero values, except if
281 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
283 *) mod_policy: Add a new testing module to help server administrators
284 enforce a configurable level of protocol compliance on their
285 servers and application servers behind theirs. [Graham Leggett]
287 *) mod_firehose: Add a new debugging module able to record traffic
288 passing through the server in such a way that connections and/or
289 requests be reconstructed and replayed. [Graham Leggett]
