1181 bison instead of yacc. [Stefan Fritsch]
1183 *) mod_disk_cache: Change on-disk header file format to support the
1184 link of the device/inode of the data file to the matching header
1185 file, and to support the option of not writing a data file when
1186 the data file is empty. [Graham Leggett]

1214 capture a stale backend response, perform If-Modified-Since requests
1215 against the backend, and serving from the cache all 304 responses.
1216 This restores pre-2.2.4 cache behavior. [William Rowe]
1218 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
1219 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop

1237 variable being echoed or set to be decoded and then encoded as separate
1238 steps. PR47686 [Graham Leggett]
1240 *) mod_cache: Add a discrete commit_entity() provider function within the
1241 mod_cache provider interface which is called to indicate to the
1242 provider that caching is complete, giving the provider the opportunity
1243 to commit temporary files permanently to the cache in an atomic
1244 fashion. Replace the inconsistent use of error cleanups with a formal
1245 set of pool cleanups attached to a subpool, which is destroyed on error.
1248 *) mod_cache: Change the signature of the store_body() provider function
1249 within the mod_cache provider interface to support an "in" brigade
1250 and an "out" brigade instead of just a single input brigade. This
1251 gives a cache provider the option to consume only part of the brigade
1252 passed to it, rather than the whole brigade as was required before.
1253 This fixes an out of memory and a request timeout condition that would
1254 occur when the original document was a large file. Introduce
1255 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
1256 the amount of data to attempt to cache at a time. [Graham Leggett]

1266 to return cached content at all, and respect a "Cache-Control:
1267 no-cache" header from a client. Previously, "no-cache" would
1268 behave like "max-age=0". [Graham Leggett]

2258 null value. [David Shane Holden <dpejesh apache.org>]
2260 *) core, authn/z: Determine registered authn/z providers directly in
2261 ap_setup_auth_internal(), which allows optional functions that just
2262 wrapped ap_list_provider_names() to be removed from authn/z modules.
2265 *) authn/z: Convert common provider version strings to macros.

2269 ap_location_walk(), don't look past the start of an empty string
2270 such as that created by a <Location ""> directive.
2273 *) core, mod_proxy: If a kept_body is present, it becomes safe for
2274 subrequests to support message bodies. Make sure that safety
2275 checks within the core and within the proxy are not triggered
2276 when kept_body is present. This makes it possible to embed
2277 proxied POST requests within mod_include. [Graham Leggett]

2280 up before reading the login form. Make sure the kept body filter
2281 is correctly inserted to ensure the body can be read a second
2282 time safely should the authn be successful. [Graham Leggett,

2337 volume sites where server bound sessions are too resource intensive.

2341 attempts at saving persistent sessions across requests.
2344 *) core, authn/z: Avoid calling access control hooks for internal requests
2345 with configurations which match those of initial request. Revert to
2346 original behaviour (call access control hooks for internal requests
2347 with URIs different from initial request) if any access control hooks or
2348 providers are not registered as permitting this optimization.
