295 of aborting. If a specific module is requested with --enable-XXX=yes,
296 missing dependencies will still cause configure to exit with an error.
297 [Stefan Fritsch]
298
299 *) mod_ldap: Revert the integration of apr-ldap as ap_ldap which was done
300 in 2.3.13. [Stefan Fritsch]

347 *) mod_socache_dc: use correct build variable MOD_SOCACHE_DC_LDADD
348 instead of MOD_SOCACHE_LDADD in build macro. [Rainer Jung]
349
350 *) mod_lua, mod_deflate: respect platform specific runpath linker
351 flag. [Rainer Jung]
352
353 *) configure: Only link the httpd binary against PCRE. No other support
354 binary needs PCRE. [Rainer Jung]

357 they have been enabled implicitely. [Rainer Jung]
358

412 [Stefan Fritsch]

415 new context_document_root and context_prefix which provide information
416 about non-global URI-to-directory mappings (from e.g. mod_userdir or
417 mod_alias) to scripts. PR 49705. [Stefan Fritsch]

969 passed to it, rather than the whole brigade as was required before.
970 This fixes an out of memory and a request timeout condition that would

1900 the buffer, not to the final brigade. [Graham Leggett]
1901
1902 *) mod_buffer: Optimise the buffering of heap buckets when the heap
1903 buckets stay exactly APR_BUCKET_BUFF_SIZE long. [Graham Leggett,
1904 Ruediger Pluem]
1905
1906 *) mod_buffer: Optional support for buffering of the input and output
1907 filter stacks. Can collapse many small buckets into fewer larger
1908 buckets, and prevents excessively small chunks being sent over
1909 the wire. [Graham Leggett]
1910
1911 *) mod_privileges: new module to make httpd on Solaris privileges-aware
1912 and to enable different virtualhosts to run with different
1913 privileges and Unix user/group IDs [Nick Kew]

1915 *) mod_mem_cache: this module has been removed. [William Rowe]
1916
1917 *) authn/z: Remove mod_authn_default and mod_authz_default.
1918 [Chris Darroch]
1919

1921 logic replicate 2.2.x authz logic, and replace <Satisfy*>, Reject,
1922 and AuthzMergeRules directives with Match, <Match*>, and AuthzMerge

1959 faked directly after login. [Graham Leggett]
1960

1962 within the output headers and error output headers, so that the
1963 session is maintained across redirects. [Graham Leggett]
1964
1965 *) mod_auth_form: Make sure the logged in user is populated correctly
1966 after a form login. Fixes a missing REMOTE_USER variable directly
1967 following a login. [Graham Leggett]
1968
1969 *) mod_session_cookie: Make sure that cookie attributes are correctly
1970 included in the blank cookie when cookies are removed. This fixes an
1971 inability to log out when using mod_auth_form. [Graham Leggett]
1972

1974 null value. [David Shane Holden <dpejesh apache.org>]
1975
1976 *) core, authn/z: Determine registered authn/z providers directly in

1978 wrapped ap_list_provider_names() to be removed from authn/z modules.

1987 [Chris Darroch]

1989 *) core, mod_proxy: If a kept_body is present, it becomes safe for
1990 subrequests to support message bodies. Make sure that safety
1991 checks within the core and within the proxy are not triggered
1992 when kept_body is present. This makes it possible to embed
1993 proxied POST requests within mod_include. [Graham Leggett]
1994
1995 *) mod_auth_form: Make sure the input filter stack is properly set
1996 up before reading the login form. Make sure the kept body filter
1997 is correctly inserted to ensure the body can be read a second
1998 time safely should the authn be successful. [Graham Leggett,
1999 Ruediger Pluem]
2000
2001 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
2002 hook instead of during fixups. Add a safety check to ensure the
2003 filters cannot be inserted more than once. [Graham Leggett,

2010
2011 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
2012 for both in- and out-put headers; and replace it by a single
2013 ap_cache_cacheable_headers() wrapped in a in- and out-put
2014 specific ap_cache_cacheable_headers_in()/out(). The latter
2015 which will also merge error and ensure content-type. To keep
2016 cache modules consistent with ease. This API change bumps
2017 up the minor MM by one [Dirk-Willem van Gulik].
2018
2019 *) Move the KeptBodySize directive, kept_body filters and the
2020 ap_parse_request_body function out of the http module and into a
2021 new module called mod_request, reducing the size of the core.

2024 *) mod_dbd: Handle integer configuration directive parameters with a
2025 dedicated function.
2026
2027 *) Change the directives within the mod_session* modules to be valid
2028 both inside and outside the location/directory sections, as

2043 session information in a SQL database via the dbd interface. Useful
2044 for sites where session privacy is important. [Graham Leggett]
2045
2046 *) mod_session_crypto: Add a session encoding implementation capable
2047 of encrypting and decrypting sessions wherever they may be stored.
2048 Introduces a level of privacy when sessions are stored on the
2049 browser. [Graham Leggett]
2050
2051 *) mod_session_cookie: Add a session implementation capable of storing
2052 session information within cookies on the browser. Useful for high
2053 volume sites where server bound sessions are too resource intensive.

2056 *) mod_session: Add a generic session interface to unify the different
2057 attempts at saving persistent sessions across requests.

2059
2060 *) core, authn/z: Avoid calling access control hooks for internal requests
2061 with configurations which match those of initial request. Revert to
2062 original behaviour (call access control hooks for internal requests
2063 with URIs different from initial request) if any access control hooks or
2064 providers are not registered as permitting this optimization.
2065 Introduce wrappers for access control hook and provider registration
2066 which can accept additional mode and flag data. [Chris Darroch]
2067

2069 This is adapted from mod_include, which is the first module
2070 to use the new API.
2071 [Nick Kew]
2072
2073 *) mod_authz_dbd: When redirecting after successful login/logout per

2075 first row returned by database query instead of last row.
