  *) 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]

  *) mod_deflate: Extend the DeflateFilterNote directive to
     allow accurate logging of the filter's in- and outstream.
     [André Malo]

  *) Use saner default config values for suexec. PR 15713.
     [Thom May <thom@planetarytramp.net>]

  *) Allow 'make depend' to work with non-GCC compilers.
     [Justin Erenkrantz]

  *) mod_cache: Fix PR 15113, a core dump in cache_in_filter when
     a redirect occurs. The code was passing a format string and
     integer to apr_pstrcat. Changed to apr_psprintf.
     [Paul J. Reder]

  *) Added character set support to mod_auth_LDAP to allow it to 
     convert extended characters used in the user ID to UTF-8 
     before authenticating against the LDAP directory. The new
     directive AuthLDAPCharsetConfig is used to specify the config
     file that contains the character set conversion table.
     [Brad Nicholes]
     
  *) Fix a bug where we leak fd's until the end of a keepalive 
     connection, which may result in:
       (24)Too many open files: file permissions deny server access
     especially on threaded servers.  [Greg Ames]

  *) 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
     for ap_post_read_request, since that is the only opportunity for
     modules to handle Expect extensions.  [Justin Erenkrantz]

  [Apache 2.1.0-dev includes those bug fixes and changes with the
   Apache 2.0.xx tree as documented, and except as noted, below.]

  *) Don't remove the Content-Length from responses in mod_proxy
     PR: 8677 [Brian Pane]

  *) Ensure LDAP version is set to v3 on every bind. PR 14235.
     [Sergey A. Lipnevich <sergeyli@pisem.net>]

  *) Fix mod_ldap to open an existing shared memory file should one
     already exist. PR 12757. [Scooter Morris <scooter@gene.com>, 
     Graham Leggett]

  *) Fix the ulimit command used by apachectl on Tru64.  PR 13609.
     [Joseph Senulis <Joseph.Senulis@dnr.state.wi.us>, Jeff Trawick]

  *) Change the ulimit command used by apachectl on AIX so that it
     works in all locales.  [Jeff Trawick]

  *) mod_ext_filter: Fix a problem building argument lists which 
     occasionally caused exec to fail.  PR 15491.  [Jeff Trawick]

Changes with Apache 2.0.44

  *) mod_autoindex: Bring forward the IndexOptions IgnoreCase option
     from Apache 1.3.  PR 14276
     [David Shane Holden <dpejesh@yahoo.com>, William Rowe]

  *) mod_mime: Workaround to prevent a segfault if r->filename=NULL
     [Brian Pane]

  *) Reorder the definitions for mod_ldap and mod_auth_ldap within
     config.m4 to make sure the parent mod_ldap is defined first.
     This ensures that mod_ldap comes before mod_auth_ldap in the
     httpd.conf file, which is necessary for mod_auth_ldap to load.
     PR 14256  [Graham Leggett]

  *) Fix the building of cgi command lines when the query string
     contains '='.  PR 13914  [Ville Skyttä <ville.skytta@iki.fi>,
     Jeff Trawick]

  *) Rename CacheMaxStreamingBuffer to MCacheMaxStreamingBuffer. Move
     implementation of MCacheMaxStreamingBuffer from mod_cache to
     mod_mem_cache. MCacheMaxStreamingBuffer now defaults to the
     lesser of 100,000 bytes or MCacheMaxCacheObjectSize. This should 
     eliminate the need for explicitly coding MCacheMaxStreamingBuffer
     in most configurations. [Bill Stoddard]

  *) Replace APU_HAS_LDAPSSL_CLIENT_INIT with APU_HAS_LDAP_NETSCAPE_SSL
     as set by apr-util in util_ldap.c. This should allow mod_ldap
     to work with the Netscape/Mozilla LDAP library. [Øyvin Sømme
     <somme@oslo.westerngeco.slb.com>, Graham Leggett]

  *) Fix critical bug in new --enable-v4-mapped configure option
     implementation which broke IPv4 listening sockets on some
     systems.  [hiroyuki hanai <hanai@imgsrc.co.jp>]

  *) mod_setenvif: Fix BrowserMatchNoCase support for non-regex
     patterns [André Malo <nd@perlig.de>]

  *) Add version string to provider API.  [Justin Erenkrantz]

  *) build: './configure && make' now works without an in-tree
     apr and apr-util. [Wilfredo Sanchez]

  *) mod_negotiation: Set the appropriate mime response headers
     (Content-Type, charset, Content-Language and Content-Encoding)
     for negotated type-map "Body:" responses (such as the error
     pages.)  [André Malo <nd@perlig.de>]

  *) mod_log_config: Allow '%%' escaping in CustomLog format
     strings to insert a literal, single '%'.
     [André Malo <nd@perlig.de>]

  *) mod_autoindex: AddDescription directives for directories
     now work as in Apache 1.3, where no trailing '/' is
     specified on the directory name.  Previously, the trailing
     '/' *had* to be specified, which was incompatible with
     Apache 1.3.  PR 7990  [Jeff Trawick]

Paul J. Reder committed
  *) Fix for PR 14556. The expiry calculations in mod_cache were
     trying to perform "now + ((date - lastmod) * factor)" where
     date == lastmod resulting in "now + 0". The code now follows
     the else path (using the default expiration) if date is
     equal to lastmod. [rx@armstrike.com (Sergey), Paul J. Reder]

  *) Use AP_DECLARE in the debug versions of ap_strXXX in case the
     default calling convention is not the same as the one used by
     AP_DECLARE.  [Juan Rivera <Juan.Rivera@citrix.com>]

  *) mod_cache: Don't cache response header fields designated
     as hop-by-hop headers in HTTP/1.1 (RFC 2616 Section 13.5.1).
     [Estrade Matthieu <estrade-m@ifrance.com>, Brian Pane]

  *) mod_cgid: Handle environment variables containing newlines.
     PR 14550  [Piotr Czejkowski <apache@czarny.eu.org>, Jeff
     Trawick]

  *) Move mod_ext_filter out of experimental and into filters.
     [Jeff Trawick]

  *) Fixed a memory leak in mod_deflate with dynamic content.
     PR 14321  [Ken Franken <kfranken@decisionmark.com>]

  *) Add --[enable|disable]-v4-mapped configure option to control
     whether or not Apache expects to handle IPv4 connections
     on IPv6 listening sockets.  Either setting will work on 
     systems with the IPV6_V6ONLY socket option.  --enable-v4-mapped
     must be used on systems that always allow IPv4 connections on
     IPv6 listening sockets.  PR 14037 (Bugzilla), PR 7492 (Gnats)
     [Jeff Trawick]

  *) This fixes a problem where the underlying cache code
     indicated that there was one more element on the cache
     than there actually was. This happened since element 0
     exists but is not used. This code allocates the correct
     number of useable elements and reports the number of
     actually used elements. The previous code only allowed
     MCacheMaxObjectCount-1 objects to be stored in the
     cache. [Paul J. Reder]

  *) mod_setenvif: Add SERVER_ADDR special keyword to allow
     envariable setting according to the server IP address
     which received the request.  [Ken Coar]

  *) mod_cgid: Terminate CGI scripts when the client connection 
     drops.  PR 8388  [Jeff Trawick]

  *) Rearrange OpenSSL engine initialization to support RAND 
     redirection on crypto accelerator. 
     [Frederic DONNAT <frederic.donnat@zencod.com>]

  *) Always emit Vary header if mod_deflate is involved in the
     request.  [Andre Malo <nd@perlig.de>]

  *) mod_isapi: Stop unsetting the 'empty' query string result with
     a NULL argument in ecb->lpszQueryString, eliminating segfaults
     for some ISAPI modules.  PR 14399
     [Detlev Vendt <detlev.vendt@brillit.de>]
