*) mod_dbd: Stash DBD connections in request_config of initial request

only, or else sub-requests and internal redirections may cause

entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]

*) mod_mem_cache: Increase the minimum and default value for

MCacheMinObjectSize from 0 to 1, as a MCacheMinObjectSize of 0 does not

make sense and leads to a division by zero. PR 40576.

on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]

*) The LockFile directive, which specifies the location of

the accept() mutex lockfile, is deprecated. Instead, the

AcceptMutex directive now takes an optional lockfile

location parameter, ala SSLMutex. [Jim Jagielski]

*) mod_authn_dbd: Export any additional columns queried in the SQL select

into the environment with the name AUTHENTICATE_<COLUMN>. This brings

mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]

*) mod_dbd: Key the storage of prepared statements on the hex string

value of server_rec, rather than the server name, as the server name

*) sendfile_nonblocking() takes the _brigade_ as an argument, gets

the first bucket from the brigade, finds it not to be a FILE

*) ap_get_server_version() has been removed. Third-party modules must

now use ap_get_server_banner() or ap_get_server_description().

[Jeff Trawick]

*) All MPMs: Introduce a check_config phase between pre_config and

open_logs, to allow modules to review interdependent configuration

directive values and adjust them while messages can still be logged

to the console. Handle relevant MPM directives during this phase

and format messages for both the console and the error log, as

appropriate. [Chris Darroch]

*) mod_proxy: don't URLencode tilde in path component

[Stijn Hoop <stijn sandcat.nl>]

*) mpm_winnt: Fix return values from wait_for_many_objects.

The return value is index to the signaled thread in the

creted_threads array. We can not use WAIT_TIMEOUT because

his value is defined as 258, thus limiting the MaxThreads

to that value. [Mladen Turk]

*) core: Do not allow internal redirects like the DirectoryIndex of mod_dir

to circumvent the symbolic link checks imposed by FollowSymLinks and

SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]

*) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]

configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.

*) mod_disk_cache: If possible, check if the size of an object to cache is

within the configured boundaries before actually saving data.

checking whether to send a Warning header for a stale response.

wildcard certificates. PR 37911. [Nick Burch <nick torchbox.com>]

*) Authz: Add the new module mod_authn_core that will provide common

authn directives such as 'AuthType', 'AuthName'. Move the directives

'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias

into mod_authn_core. [Brad Nicholes]

*) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'

into the new module mod_access_compat which can be loaded to provide

support for these directives.

[Brad Nicholes]

*) Authz: Move the 'Require' directive from the core module as well as

add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'

and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'

logic into the authorization processing. [Brad Nicholes]

*) Authz: Add the new module mod_authz_core which acts as the

authorization provider vector and contains common authz

directives. [Brad Nicholes]

*) Authz: Renamed mod_authz_dbm authz providers from 'group' and

'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]

*) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle

host-based access control provided by mod_authz_host and invoked

through the 'Require' directive. [Brad Nicholes]

*) Authz: Convert all of the authz modules from hook based to

provider based. [Brad Nicholes]

*) mod_cache: Add CacheMinExpire directive to set the minimum time in

seconds to cache a document.

[Brian Akins <brian.akins turner.com>, Ruediger Pluem]

*) Fix typo in ProxyStatus syntax error message.

[Christophe Jaillet <christophe.jaillet wanadoo.fr>]

*) Asynchronous write completion for the Event MPM. [Brian Pane]

*) Added an End-Of-Request bucket type. The logging of a request and

the freeing of its pool are now done when the EOR bucket is destroyed.

This has the effect of delaying the logging until right after the last

of the response is sent; ap_core_output_filter() calls the access logger

indirectly when it destroys the EOR bucket. [Brian Pane]

*) Rewrite of logresolve support utility: IPv6 addresses are now supported

and the format of statistical output has changed. [Colm MacCarthaigh]

*) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]

*) Added new connection states for handler and write completion

[Brian Pane]

*) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.

[Justin Erenkrantz]

*) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
