23 SSLCertificateFile and SSLCertificateKeyFile directives, to enable
24 future algorithm agility, and deprecate the SSLCertificateChainFile
25 directive (obsoleted by SSLCertificateFile). [Kaspar Brand]
27 *) mod_proxy: Remove <Proxy ~ wildcard-url> syntax which:
28 - is equivalent to <ProxyMatch wildcard-url>
29 - has never been documented
30 - incorrectly checks parameters
34 *) FreeBSD: Disable IPv4-mapped listening sockets by default for versions
35 5+ instead of just for FreeBSD 5. PR 53824. [Jeff Trawick]
37 *) mod_auth_form: Add a debug message when the fields on a form are not
38 recognised. [Graham Leggett]
40 *) mod_ssl: Add -t -DDUMP_CA_CERTS option which dumps the filenames of all
41 configured SSL CA certificates to stdout the same way as DUMP_CERTS does.
44 *) mod_cache_disk: Fix potential hangs on Windows when using mod_cache_disk.
45 PR55833. [Eric Covener]
47 *) mod_headers: Allow the "value" parameter of Header and RequestHeader to
48 contain an ap_expr expression if prefixed with "expr=". [Eric Covener]

51 when the thread/connection relationship changes. (Currently implemented
52 only for the Event MPM; should be implemented for all async MPMs.)
55 *) mod_ssl: Don't flush when an EOS is received. Prepares mod_ssl
56 to support write completion. [Graham Leggett]
58 *) prefork: Fix long delays when doing a graceful restart.
59 PR 54852 [Jim Jagielski, Arkadiusz Miskiewicz <arekm maven pl>]
61 *) core: Add parse_errorlog_arg callback to ap_errorlog_provider
62 to allow providers to check the ErrorLog argument. [Jan Kaluza]

65 APR_INCOMPLETE. PR 55475 [Yann Ylavic <ylavic dev gmail com>]
67 *) mod_cgid: Use the servers Timeout for each read from a CGI script,
68 allow override with new CGIDRequestTimeout directive. PR43494
69 [Eric Covener, Toshikuni Fukaya <toshikuni-fukaya cybozu co jp>]
71 *) core: Add missing Reason-Phrase in HTTP response headers.
72 PR 54946. [Rainer Jung]
74 *) core: ensure any abnormal exit is reported to stderr if it's a tty.
77 *) mod_proxy: Added support for unix domain sockets as the
78 backend server endpoint [Jim Jagielski, Blaise Tarr
79 <blaise tarr gmail com>]
81 *) mod_auth_form: Make sure the optional functions are loaded even when
82 the AuthFormProvider isn't specified. [Graham Leggett]
84 *) mod_lua: Let the Inter-VM get/set functions work with a global
85 shared memory pool instead of a per-process pool. [Daniel Gruno]
87 *) ldap: Support ldaps when using the Microsoft LDAP SDK.
88 PR 54626. [Jean-Frederic Clere]
90 *) mod_proxy: Add ap_connection_reusable() for checking if a connection
91 is reusable as of this point in processing. [Jeff Trawick]
93 *) mod_authnz_ldap: Change default value of AuthLDAPMaxSubGroupDepth to 0
94 to avoid performance problems when subgroups aren't in use. [Eric Covener]
96 *) mod_syslog: New module implementing syslog ap_error_log provider.
97 Previously, this code was part of core, now it's in separate module.
100 *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move
101 syslog support from core to new mod_syslog. [Jan Kaluza]
103 *) core: draft-ietf-httpbis-p1-messaging-23 corrections regarding
104 TE/CL conflicts. [Yann Ylavic <ylavic.dev gmail com>, Jim Jagielski]
106 *) mod_proxy_fcgi: Use apr_socket_timeout_get instead of hard-coded
107 30 seconds timeout. [Jan Kaluza]
109 *) WinNT MPM: If ap_run_pre_connection() fails or sets c->aborted, don't
110 save the socket for reuse by the next worker as if it were an
111 APR_SO_DISCONNECTED socket. Restores 2.2 behavior. [Eric Covener]
113 *) mod_lua: Add a logging hook for modifying/skipping logs. [Daniel Gruno]
115 *) mod_status, mod_echo: Fix the display of client addresses.
116 They were truncated to 31 characters which is not enough for IPv6 addresses.
117 PR 54848 [Bernhard Schmidt <berni birkenwald de>]
119 *) mod_lua: If the first yield() of a LuaOutputFilter returns a string, it should
120 be prefixed to the response as documented. [Eric Covener]
122 *) mod_lua: Remove ETAG, Content-Length, and Content-MD5 when a LuaOutputFilter
123 is configured without mod_filter. [Eric Covener]
125 *) mod_lua: Register LuaOutputFilter scripts as changing the content and
126 content-length by default, when run my mod_filter. Previously,
127 growing or shrinking a response that started with Content-Length set
128 would require mod_filter and FilterProtocol change=yes. [Eric Covnener]
130 *) mod_lua: Return a 500 error if a LuaHook* script doesn't return a
131 numeric return code. [Eric Covener]
133 *) mod_authnz_fcgi: New module to enable FastCGI authorizer
134 applications to authenticate and/or authorize clients.
137 *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers.
140 *) mod_unique_id: Use output of the PRNG rather than IP address and
141 pid, avoiding sleep() call and possible DNS issues at startup,
142 plus improving randomness for IPv6-only hosts.
143 [Jan Kaluza <jkaluza redhat.com>]
145 *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
146 filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special
147 filter "none" to be specified in AuthLDAPURL. [Eric Covener]
149 *) mod_file_cache: mod_file_cache should be able to serve files that
150 haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]
152 *) core: merge AllowEncodedSlashes from the base configuration into
153 virtual hosts. [Eric Covener]
155 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
158 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
161 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
162 been configured with -D Z_PREFIX, which redefines the token "deflate".
165 *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
166 previously limited to 64MB. [Jens Låås <jelaas gmail.com>]
168 *) mod_auth_digest: Use the secret when generating nonces in all cases and
169 not only when AuthName is used in .htaccess files (this change may cause
170 problems if used with round robin load balancers). Don't regenerate the
171 secret on graceful restarts. PR 54637 [Stefan Fritsch]
173 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
174 from the HTTP_IN filter, parse chunks in a single pass with zero copy.
175 Reduce memory usage by 48 bytes per request. [Graham Leggett]
177 *) core: Stop the HTTP_IN filter from attempting to write error buckets
178 to the output filters, which is bogus in the proxy case. Create a
179 clean mapping from APR codes to HTTP status codes, and use it where
180 needed. [Graham Leggett]
182 *) mod_proxy: Ensure network errors detected by the proxy are returned as
183 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
184 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
186 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
187 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
188 <alejandro.alvarez.ayllon cern.ch>]
190 *) core, mod_ssl: Enable the ability for a module to reverse the sense of
191 a poll event from a read to a write or vice versa. This is a step on
192 the way to allow mod_ssl taking full advantage of the event MPM.
195 *) mod_ldap: LDAP connections used for authentication were not respecting
196 LDAPConnectionPoolTimeout. PR 54587
198 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
200 *) mod_proxy_html: process parsed comments immediately.
201 Fixes bug where parsed comments may be lost. [Nick Kew]
203 *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew]
205 *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional"
206 HTML/XHTML [Nick Kew]
208 *) core: Add option to add valgrind support. Use it to reduce false positive
209 warnings in mod_ssl. [Stefan Fritsch]
211 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
212 Cache the result of the most recent password hash verification for every
213 keep-alive connection. This saves some expensive calculations.
216 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
217 MSIE 3. [Stefan Fritsch]
219 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
220 conformance or to only log the found problems. [Stefan Fritsch]
222 *) core: Correctly parse an IPv6 literal host specification in an absolute
223 URL in the request line. [Stefan Fritsch]
225 *) mod_ssl: Add support for OpenSSL configuration commands [Stephen Henson]
229 *) core: Add LogLevelOverride directive that allows to override the
230 loglevel for clients from certain IPs. This also works for things
231 like the SSL handshake where <If> LogLevel ... </If> is evaluated
232 too late. [Stefan Fritsch]
234 *) core: Add new directive Warning to issue warnings from a configuration
235 file. Both Warning and Error now generate a timestamped log message.
238 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
239 variables. [Stefan Fritsch]
241 *) core: New directive RegisterHttpMethod for registering non-standard
242 HTTP methods. [Stefan Fritsch]
244 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
245 support. [Stefan Fritsch]
247 *) mod_allowhandlers: New module to forbid specific handlers for specific
248 directories. [Stefan Fritsch]
250 *) mod_systemd: New module, for integration with systemd on Linux.
251 [Jan Kaluza <jkaluza redhat.com>]
253 *) WinNT MPM: Store pid and generation for each thread in scoreboard
254 to allow tracking of threads from exiting children via mod_status
255 or other such mechanisms. [Jeff Trawick]
257 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
258 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
259 - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
261 - mod_cache: thundering herd lock directory
262 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
263 - mod_ldap: shared memory cache
264 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
267 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
268 setuid/setgid capability bits rather than a setuid root binary.
271 *) suexec: Add support for logging to syslog as an alternative to logging
272 to a file; configure --without-suexec-logfile --with-suexec-syslog.
275 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
276 [Matthew Steele <mdsteele google.com>]
278 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
279 be compiled by the build compiler instead of the host compiler.
280 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
281 PR 51257. [Guenter Knauf]
283 *) core: In maintainer mode, replace apr_palloc with a version that
284 initializes the allocated memory with non-zero values, except if
285 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
287 *) mod_policy: Add a new testing module to help server administrators
288 enforce a configurable level of protocol compliance on their
289 servers and application servers behind theirs. [Graham Leggett]
291 *) mod_firehose: Add a new debugging module able to record traffic
292 passing through the server in such a way that connections and/or
293 requests be reconstructed and replayed. [Graham Leggett]
