1726 empty parameter list for the AllowMethods directive. [Rainer Jung]
1728 *) configure: Update selection of modules for 'all' and 'most'. 'all' will
1729 now enable all modules except for example and test modules. Make the
1730 selection for 'most' more useful (including ssl and proxy). Both 'all'
1731 and 'most' will now disable modules if dependencies are missing instead
1732 of aborting. If a specific module is requested with --enable-XXX=yes,

1863 parser. The old parser can still be used by setting the new directive
1864 SSILegacyExprParser. [Stefan Fritsch]

1867 mode that does not allow to bypass request access restrictions; new
1868 variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an

1929 not being available during graceful restarts. PR 48958. [Stefan Fritsch]

2086 authorization directives were mixed. [Stefan Fritsch]
2088 *) mod_authn_socache: change directive name from AuthnCacheProvider
2089 to AuthnCacheProvideFor. The term "provider" is overloaded in
2090 this module, and we should avoid confusion between the provider
2091 of a backend (AuthnCacheSOCache) and the authn provider(s) for
2092 which this module provides cacheing (AuthnCacheProvideFor).
2095 *) mod_proxy_http: Allocate the fake backend request from a child pool
2096 of the backend connection, instead of misusing the pool of the frontend
2097 request. Fixes a thread safety issue where buckets set aside in the
2098 backend connection leak into other threads, and then disappear when
2099 the frontend request is cleaned up, in turn causing corrupted buckets

2364 capture a stale backend response, perform If-Modified-Since requests
2365 against the backend, and serving from the cache all 304 responses.
2366 This restores pre-2.2.4 cache behavior. [William Rowe]
2368 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer

2387 variable being echoed or set to be decoded and then encoded as separate
2388 steps. PR47686 [Graham Leggett]
2390 *) mod_cache: Add a discrete commit_entity() provider function within the
2391 mod_cache provider interface which is called to indicate to the
2392 provider that caching is complete, giving the provider the opportunity
2393 to commit temporary files permanently to the cache in an atomic
2394 fashion. Replace the inconsistent use of error cleanups with a formal
2395 set of pool cleanups attached to a subpool, which is destroyed on error.
2398 *) mod_cache: Change the signature of the store_body() provider function
2399 within the mod_cache provider interface to support an "in" brigade
2400 and an "out" brigade instead of just a single input brigade. This
2401 gives a cache provider the option to consume only part of the brigade
2402 passed to it, rather than the whole brigade as was required before.
2403 This fixes an out of memory and a request timeout condition that would
2404 occur when the original document was a large file. Introduce
2405 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
2406 the amount of data to attempt to cache at a time. [Graham Leggett]

2416 to return cached content at all, and respect a "Cache-Control:
2417 no-cache" header from a client. Previously, "no-cache" would
2418 behave like "max-age=0". [Graham Leggett]

3325 based on heartbeats. [Paul Querna]
3327 *) mod_heartmonitor: New module to collect heartbeats, and write out a file
3328 so that other modules can load balance traffic as needed. [Paul Querna]

3331 server is online. [Paul Querna]
3333 *) mod_buffer: Honour the flush bucket and flush the buffer in the
3334 input filter. Make sure that metadata buckets are written to
3335 the buffer, not to the final brigade. [Graham Leggett]
3337 *) mod_buffer: Optimise the buffering of heap buckets when the heap
3338 buckets stay exactly APR_BUCKET_BUFF_SIZE long. [Graham Leggett,
3341 *) mod_buffer: Optional support for buffering of the input and output
3342 filter stacks. Can collapse many small buckets into fewer larger
3343 buckets, and prevents excessively small chunks being sent over
3344 the wire. [Graham Leggett]
3346 *) mod_privileges: new module to make httpd on Solaris privileges-aware
3347 and to enable different virtualhosts to run with different
3348 privileges and Unix user/group IDs [Nick Kew]
3350 *) mod_mem_cache: this module has been removed. [William Rowe]
3352 *) authn/z: Remove mod_authn_default and mod_authz_default.

3356 logic replicate 2.2.x authz logic, and replace <Satisfy*>, Reject,
3357 and AuthzMergeRules directives with Match, <Match*>, and AuthzMerge

3364 authentication. [Chris Darroch]

3411 *) core, authn/z: Determine registered authn/z providers directly in
3412 ap_setup_auth_internal(), which allows optional functions that just
3413 wrapped ap_list_provider_names() to be removed from authn/z modules.

3420 ap_location_walk(), don't look past the start of an empty string
3421 such as that created by a <Location ""> directive.
3424 *) core, mod_proxy: If a kept_body is present, it becomes safe for
3425 subrequests to support message bodies. Make sure that safety
3426 checks within the core and within the proxy are not triggered
3427 when kept_body is present. This makes it possible to embed
3428 proxied POST requests within mod_include. [Graham Leggett]
3430 *) mod_auth_form: Make sure the input filter stack is properly set
3431 up before reading the login form. Make sure the kept body filter
3432 is correctly inserted to ensure the body can be read a second
3433 time safely should the authn be successful. [Graham Leggett,

3447 for both in- and out-put headers; and replace it by a single
3448 ap_cache_cacheable_headers() wrapped in a in- and out-put
3449 specific ap_cache_cacheable_headers_in()/out(). The latter

3451 cache modules consistent with ease. This API change bumps
3452 up the minor MM by one [Dirk-Willem van Gulik].
3454 *) Move the KeptBodySize directive, kept_body filters and the
3455 ap_parse_request_body function out of the http module and into a
3456 new module called mod_request, reducing the size of the core.
3459 *) mod_dbd: Handle integer configuration directive parameters with a

3467 in using an HTML form, storing the credentials within mod_session.
3470 *) Add a function to the http filters that is able to parse an HTML
3471 form request with the type of application/x-www-form-urlencoded.

3482 of encrypting and decrypting sessions wherever they may be stored.
3483 Introduces a level of privacy when sessions are stored on the

3486 *) mod_session_cookie: Add a session implementation capable of storing
3487 session information within cookies on the browser. Useful for high
3488 volume sites where server bound sessions are too resource intensive.
3491 *) mod_session: Add a generic session interface to unify the different
3492 attempts at saving persistent sessions across requests.
3495 *) core, authn/z: Avoid calling access control hooks for internal requests
3496 with configurations which match those of initial request. Revert to
3497 original behaviour (call access control hooks for internal requests
3498 with URIs different from initial request) if any access control hooks or
3499 providers are not registered as permitting this optimization.
