  *) Get mod_auth_ldap to retry connections on LDAP_SERVER_DOWN.
     [Thomas Bennett <thomas.bennett@eds.com>, Graham Leggett]

  *) Make sure the contents of the WWW-Authenticate header is
     passed on a 4xx error by proxy. Previously all headers
     were dropped, resulting in the browser being unable to
     authenticate. [Dr Richard Reiner <rreiner@fscinternet.com>,
     Richard Danielli <rdanielli@fscinternet.com>, Graham Wiseman
     <gwiseman@fscinternet.com>, David Henderson
     <dhenderson@fscinternet.com>]

  *) Make mod_cache's CacheMaxStreamingBuffer directive work
     properly for virtual hosts that override server-wide mod_cache
     setttings.  [Matthieu Estrade <estrade-m@ifrance.com>]

  *) Add ap_register_provider/ap_lookup_provider API.
     [John K. Sterling <john@sterls.com>, Justin Erenkrantz]

  *) Add -p option to apxs to allow programs to be compiled with apxs.
     [Justin Erenkrantz]

  *) Rewrite of aaa modules to an authn/authz model.

Changes with Apache 2.0.41
  *) The protocol version (eg: HTTP/1.1) in the request line parsing
     is now case insensitive. [Jim Jagielski]

  *) Allow AddOutputFilterByType to add multiple filters per directive.
     [Justin Erenkrantz]

  *) Remove warnings with Sun's Forte compiler.  [Justin Erenkrantz]

  *) Fixed mod_disk_cache's generation of 304s
     [Kris Verbeeck <Kris.Verbeeck@ubizen.com>]

  *) Add support for using fnmatch patterns in the final path
     segment of an Include statement (eg.. include /foo/bar/*.conf).
     and remove the noise on stderr during config dir processing.
     [Joe Orton <jorton@redhat.com>]

  *) mod_cache: cache_storage.c. Add the hostname and any request
     args to the key generated for caching. This provides a unique
     key for each virtual host and for each request with unique
     args. [Paul J. Reder, args code provided by Kris Verbeeck]

  *) mod_cache: Do not cache responses to GET requests with query
     URLs if the origin server does not explicitly provide an
     Expires header on the response (RFC 2616 Section 13.9)
     [Kris Verbeeck krisv@be.ubizen.com]
  *) Fix memory leak in core_output_filter.  [Justin Erenkrantz]

  *) Update OpenSSL detection to work on Darwin.
     [Sander Temme <sctemme@covalent.net>]

  *) Update the xslt and css to give the documentation a more
     modern style.
     [André Malo <nd@perlig.de>, Gernot Winkler <greh@o3media.de>]
  *) Fix some bucket memory leaks in the chunking code
     [Joe Schaefer <joe+apache@sunstarsys.com>]

  *) Add ModMimeUsePathInfo directive.  [Justin Erenkrantz]

  *) mod_cache: added support for caching streamed responses (proxy,
     CGI, etc) with optional CacheMaxStreamingBuffer setting [Brian Pane]

  *) Add image/x-icon to httpd.conf PR 10993.
     [Ian Holsman, Peter Bieringer <pb@bieringer.de>]

  *) Fix FileETags none operation.  PR 12207.
     [Justin Erenkrantz, Andrew Ho <andrew@tellme.com>]

  *) Restored the experimental leader/followers MPM to working
     condition and converted its thread synchronization from
     mutexes to atomic CAS.  [Brian Pane]

  *) Fix Logic on non-html file removal in mod_deflate
     [Kris Verbeeck <Kris.Verbeeck@ubizen.com>]

  *) Fix "ab -g"'s truncated year: the last digit was cut off.
     [Leon Brocard <acme@astray.com>]

  *) mod_rewrite can now sets cookies in err_headers, uses the correct
     expiry date, and can now set the path as well
     PR 12132,12181,12172.

     [Ian Holsman / Rob Cromwell <apachechangelog@robcromwell.com>]

  *) The content-length filter no longer tries to buffer up
     the entire output of a long-running request before sending
     anything to the client.  [Brian Pane]

  *) Win32: Lower the default stack size from 1MB to 256K. This will
     allow around 8000 threads to be started per child process. 
     'EDITBIN /STACK:size apache.exe' can be used to change this 
     value directly in the apache.exe executable.
     [Bill Stoddard]

  *) Win32: Implement ThreadLimit directive in the Windows MPM.

  *) Remove CacheOn config directive since it is set but never checked.
     No sense wasting cycles on unused code. Besides, the only truly
     bug free code is deleted code. :)   [Paul J. Reder]

  *) BufferLogs are now run-time enabled, and the log_config now has 2 new
     callbacks to allow a 3rd party module to actually do the writing of the
     log file [Ian Holsman]

  *) Correct ISAPIReadAheadBuffer to default to 49152, per mod_isapi docs.
     [André Malo, Astrid Keßler <kess@kess-net.de>]

  *) Fix Segfault in mod_cache. [Kris Verbeeck <Kris.Verbeeck@ubizen.com>]

  *) Fix a null pointer dereference in the merge_env_dir_configs
     function of the mod_env module. PR 11791
     [Paul J. Reder]

  *) New option to ServerTokens 'maj[or]'. Only show the major version
     Also Surfaced this directive in the standard config (default FULL)
     [Ian Holsman]

  *) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
     maps.  The dbm type (e.g., ndbm, gdbm) can be specified on the
     RewriteMap directive.  PR 10644  [Jeff Trawick]
  *) Fixed mod_rewrite's RewriteMap prg: support so that request/response
     pairs will no longer get out of sync with each other.  PR 9534
     [Cliff Woolley]

  *) Fix bug where environment or command line arguments containing 
     non-ASCII-7 characters would cause the Win32 child process creation
     to fail.  PR 11854  [William Rowe]

  *) Bug #11213.. make module loading error messages more informative 
     [Ian Darwin <Ian779@darwinsys.com>]

  *) mod_disk_cache works much better. This module should still
     be considered experimental. [Eric Prud'hommeaux]
  *) Performance improvement for keepalive requests: when setting
     aside a small file for potential concatenation with the next
     response on the connection, set aside the file descriptor rather
     than copying the file into the heap.  [Brian Pane]

  *) SECURITY: [CAN-2002-0661] Close a very significant security hole that 
     applies only to the Win32, OS2 and Netware platforms.  Unix was not 
     affected, Cygwin may be affected.  Certain URIs will bypass security
     and allow users to invoke or access any file depending on the system 
     configuration.  Without upgrading, a single .conf change will close 
     the vulnerability.  Add the following directive in the global server
     httpd.conf context before any other Alias or Redirect directives;
         RedirectMatch 400 "\\\.\."
     Reported by Auriemma Luigi <bugtest@sitoverde.com>.
     [Brad Nicholes]

  *) SECURITY:  Close a path-revealing exposure in multiview type
     map negotiation (such as the default error documents) where the
     module would report the full path of the typemapped .var file when
     multiple documents or no documents could be served based on the mime
     negotiation.  Reported by Auriemma Luigi <bugtest@sitoverde.com>.
     [CAN-2002-0654]  [William Rowe]

  *) SECURITY:  Close a path-revealing exposure in cgi/cgid when we 
     fail to invoke a script.  The modules would report "couldn't create 
     child process /path-to-script/script.pl" revealing the full path
     of the script.  Reported by Jim Race <jrace@qualys.com>.
     [CAN-2002-0654]  [Bill Stoddard]

  *) Set aside the apr-iconv and apr_xlate() features for the Win32
     build of 2.0.40 so development can be completed.  A patch, from
     <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
     will be available for those that wish to work with apr-iconv.
     [William Rowe]

  *) Fix proxy so that it is possible to access ftp: URLs via a proxy
     chain. [Peter Van Biesen <peter.vanbiesen@vlafo.be>]

  *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
     set to 1, so we can exclude things from the general case with
     browsermatch. [Ian Holsman, Andre Schild <A.Schild@aarboard.ch>]
