+ incompatible change of mod_include's external API. [André Malo]
+
+ *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
+ PR 14223. [André Malo]
+

+ not specified. [Justin Erenkrantz]

+
+ *) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot.
+ [André Malo]

+ [André Malo]
+
+ *) mod_actions: Propagate the handler name to the action script via
+ the REDIRECT_HANDLER environment variable. [André Malo]
+
+ *) mod_actions: Introduce the "virtual" modifier to the Action directive,
+ which allows the use of handlers for virtual locations. PR 8431.
+ [André Malo]
+
+ *) mod_speling: Recognize AcceptPathInfo setting for the particular
+ location. Default is to reject path information. PR 21059.

+ [Philipp Reisner <philipp.reisner linbit.com>]
+
+ *) Fix some broken log messages in WinNT MPM.

+ for gprof support. [Jim Carlson <jcarlson jnous.com>]
+
+ *) Fix a compile failure with recent OpenSSL and picky compilers
+ (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
+
+ *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
+ the INCLUDE path to be defined properly.
+ PR 11310. [Geoff Thorpe <geoff geoffthorpe.net>]
+
+ *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
+
+ *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
+ autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
+ [Geoff Thorpe <geoff geoffthorpe.net>]
+
+ *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
+ [Ian Holsman, André Malo]
+
+ *) mod_negotiation: quality values are now parsed independent from
+ the current locale. level values are now really parsed as integers.
+ PR 17564. [André Malo]
+
+ *) Extend mod_negotiation to evaluate the environment variables
+ no-gzip and gzip-only-text/html the same way as mod_deflate does.
+ [André Malo]
+
+ *) mod_rewrite: Fix some problems reporting errors with mapping
+ programs (RewriteMap prg:/something). [Jeff Trawick]
+
+ *) Return 413 if chunk-ext-header is too long rather than reading from
+ the truncated line. PR 15857. [Justin Erenkrantz]
+
+ *) Allow restart of httpd to occur even with syntax errors in the config
+ file. PR 16813. [Justin Erenkrantz]
+
+ *) Use APR_LAYOUT instead of APACHE_LAYOUT in configure. PR 15679.
+ [Justin Erenkrantz]
+
+ *) Remove files on 'make distclean' that should be. PR 15592.
+ [Justin Erenkrantz]

+ [Justin Erenkrantz]
+
+ *) mod_log_config change optional hook to return previous handler
+ [Ian Holsman]
+
+ *) Forward port of mod_actions' ability to handle arbitrary methods
+ with the Script directive. [André Malo]
+
+ *) Let suexec send a message to stderr, if it failed or its policy
+ was violated. This message appears in the error log and allows
+ for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
+
+ *) Modify buildconf to copy all required files into httpd's tree.
+ [Thom May <thom planetarytramp.net>]
+
+ *) Allow mod_dav to do weak entity comparison functions.
+ [Justin Erenkrantz]
+
+ *) Move RFC 1413 ident requests from core to new module mod_ident.
+ [André Malo]
+
+ *) Add mod_authz_owner - a forward port of "Require file-owner"
+ and "Require file-group", which was already present in version
+ 1.3.21. [André Malo]
+
+ *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
+ [Justin Erenkrantz]

+ *) Replace some of the mutex locking in the worker MPM with
+ atomic operations for higher concurrency. [Brian Pane]
+
+ *) Allow 'make depend' to work with non-GCC compilers.
+ [Justin Erenkrantz]
+
+ *) If an httpd.conf has commented out AddModule directives,
+ apxs -i -a will add an un-commented AddModule directive for
+ the new module, which breaks the config.
+ PR: 11212 [Joe Orton]
+
+ *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
+
+ *) Move the check of the Expect request header field after the hook
