  *) Accept URLs for the ServerAdmin directive. If the supplied
     argument is not recognized as an URL, assume it's a mail address.
     PR 28174.  [André Malo, Paul Querna]

  *) initialize server arrays prior to calling ap_setup_prelinked_modules
     so that static modules can push Defines values when registering
     hooks just like DSO modules can ["Philippe M. Chiasson" <gozer cpan.org>]

  *) Small fix to allow reverse proxying to an ftp server. Previously
     an attempt to do this would try and connect to 0.0.0.0, regardless
     of the server specified. PR 24922
     [Pascal Terjan <[e-mail]>]

  *) Add the NOTICE file to the rpm spec file in compliance with the
     Apache v2.0 license. [Graham Leggett]

     instead of db3. Fixed complaints about unpackaged files.
     [Graham Leggett]
 
Changes with Apache 2.0.50

     Close a denial of service vulnerability identified by Georgi
     Guninski which could lead to memory exhaustion with certain
     input data.  [Jeff Trawick]

     PR 22030, 18348.  [Joe Orton, Jeff Trawick]

  *) mod_alias now emits a warning if it detects overlapping *Alias*
     directives.  [André Malo]

     exported on Win32 and Netware as well (minor MMN bump).  PR 28523.
     [Edward Rudd <eddie omegaware.com>, André Malo]

  *) Restore the ability to disable the use of AcceptEx on Win9x systems
     automatically (broken in 2.0.49). PR 28529.  [André Malo]

  *) <VirtualHost myhost> now applies to all IP addresses for myhost
     instead of just the first one reported by the resolver.  This
     corrects a regression since 1.3.  [Jeff Trawick]

  *) util_ldap: allow relative paths for LDAPTrustedCA to be resolved
     against ServerRoot PR#26602 [Brad Nicholes]
       
  *) SECURITY: CVE-2004-0488 (cve.mitre.org)

  *) Allow LimitRequestBody to be reset to unlimited. PR 29106
     [André Malo]

  *) Fix a bunch of cases where the return code of the regex compiler
     was not checked properly. This affects: mod_setenvif, mod_usertrack,
     mod_proxy, mod_proxy_ftp and core. PR 28218.  [André Malo]

  *) mod_logio no longer removes the EOS bucket. PR 27928.
     [Bojan Smojver <bojan rexursive.com>]

  *) htpasswd no longer refuses to process files that contain empty
     lines.  [André Malo]

  *) Regression from 1.3: At startup, suexec now will be checked for

     httpd is compiled with the shipped APR version (0.9.5).
     PR 28287.  [André Malo]

     NULL. Fix a segfault caused by a lack of bounds checking on the
     cache.  PR 24801.  [Graham Leggett]

  *) Throw an error message if an attempt is made to use the LDAPTrustedCA
     or LDAPTrustedCAType directives in a VirtualHost. PR 26390
     [Brad Nicholes]

  *) Fix a potential segfault if the bind password in the LDAP cache
     is NULL.  PR 28250.  [Jari Ahonen <jah progress.com>]

  *) Quotes cannot be used around require group and require dn
     directives, update the documentation to reflect this. Also add
     quotes around the dn and group within debug messages, to make it
     more obvious why authentication is failing if quotes are used in
     error.  PR 19304.  [Graham Leggett]

  *) The Microsoft LDAP SDK escapes filters for us, stop util_ldap
     from escaping filters twice when the backslash character is used.
     PR 24437.  [Jess Holle <jessh ptc.com>]

  *) Overhaul handling of LDAP error conditions, so that the util_ldap_*
     functions leave the connections in a sane state after errors have
     occurred. PR 27748, 17274, 17599, 18661, 21787, 24595, 24683, 27134,
     27271 [Graham Leggett]
                                                                                
  *) mod_ldap calls ldap_simple_bind_s() to validate the user
     credentials.  If the bind fails, the connection is left
     in an unbound state.  Make sure that the ldap connection
     record is updated to show that the connection is no longer
     bound. [Brad Nicholes]

  *) Ensure that lines in the request which are too long are 
     properly terminated before logging.
     [Tsurutani Naoki <turutani scphys.kyoto-u.ac.jp>]

  *) Update the bind credentials for the cached LDAP connection to 
     reflect the last bind.  This prevents util_ldap from creating 
     unnecessary connections rather than reusing cached connections.
     [Brad Nicholes]
     
  *) mod_isapi: GetServerVariable returned improperly terminated header 
     fields given "ALL_HTTP" or "ALL_RAW".  PR 20656.
     [Jesse Pelton <jsp pkc.com>]

  *) mod_isapi: GetServerVariable("ALL_RAW") returned the wrong buffer
     size.  PR 20617.  [Jesse Pelton <jsp pkc.com>]

  *) mod_dav: Fix a problem that could cause crashes when manipulating 
     locks on some platforms.  [Jeff Trawick]

  *) mod_headers no longer crashes if an empty header value should
     be added.  [André Malo]

  *) Fix segfault in mod_expires, which occured under certain
     circumstances. PR 28047.  [André Malo]

  *) htpasswd: use apr_temp_dir_get() and general cleanup
     [Guenter Knauf <eflash gmx.net>, Thom May]

  *) mod_ssl: Fix memory leak in session cache handling.  PR 26562
     [Madhusudan Mathihalli]

  *) mod_ssl: Fix potential segfaults when performing SSL shutdown from
     a pool cleanup.  PR 27945.  [Joe Orton]

  *) Add forensic logging module (mod_log_forensic).
     [Ben Laurie]

  *) logresolve: Allow size of log line buffer to be overridden at
     build time (MAXLINE).  PR 27793.  [Jeff Trawick]

  *) Fix the comment delimiter in htdbm so that it correctly parses the 
     username comment.  Also add a terminate function to allow NetWare 
     to pause the output before the screen is destroyed.
     [Guenter Knauf <eflash gmx.net>, Brad Nicholes] 
  
  *) Fix crash when Apache was started with no Listen directives.
     [Michael Corcoran <mcorcoran warpsolutions.com>]

  *) core_output_filter: Fix bug that could result in sending
     garbage over the network when module handlers construct
     bucket brigades containing multiple file buckets all referencing
     the same open file descriptor. [Bojan Smojver]

  *) Fix memory corruption problem with ap_custom_response() function.
     The core per-dir config would later point to request pool data
     that would be reused for different purposes on different requests.
     [Jeff Trawick, based on an old 1.3 patch submitted by Will Lowe]

  *) Win32: Tweak worker thread accounting routines to eliminate
     server hang when number of Listen directives in httpd.conf
     is greater than or equal to the setting of ThreadsPerChild.
     [Bill Stoddard]

Changes with Apache 2.0.49

  *) SECURITY: CVE-2004-0174 (cve.mitre.org)
     Fix starvation issue on listening sockets where a short-lived
     connection on a rarely-accessed listening socket will cause a
     child to hold the accept mutex and block out new connections until
     another connection arrives on that rarely-accessed listening socket.
     With Apache 2.x there is no performance concern about enabling the 
     logic for platforms which don't need it, so it is enabled everywhere
     except for Win32.  [Jeff Trawick]

  *) mod_cgid: Fix storage corruption caused by use of incorrect pool.
     [Jeff Trawick]

  *) Win32: find_read_listeners was not correctly handling multiple
     listeners on the Win32DisableAcceptEx path.  [Bill Stoddard]

  *) Fix bug in mod_usertrack when no CookieName is set.  PR 24483.
     [Manni Wood <manniwood planet-save.com>]

  *) Fix some piped log problems: bogus "piped log program '(null)'
     failed" messages during restart and problem with the logger
     respawning again after Apache is stopped.  PR 21648, PR 24805.
     [Jeff Trawick]

  *) Fixed file extensions for real media files and removed rpm extension
     from mime.types. PR 26079.  [Allan Sandfeld <kde carewolf.com>]

  *) Remove compile-time length limit on request strings. Length is
     now enforced solely with the LimitRequestLine config directive.
     [Paul J. Reder]

  *) mod_ssl: Send the Close Alert message to the peer before closing
     the SSL session.  PR 27428.  [Madhusudan Mathihalli, Joe Orton]

  *) SECURITY: CVE-2004-0113 (cve.mitre.org)
     mod_ssl: Fix a memory leak in plain-HTTP-on-SSL-port handling.
     PR 27106.  [Joe Orton]

  *) mod_ssl: Fix bug in passphrase handling which could cause spurious
     failures in SSL functions later.  PR 21160.  [Joe Orton]

  *) mod_log_config: Fix corruption of buffered logs with threaded
     MPMs.  PR 25520.  [Jeff Trawick]

  *) Fix mod_include's expression parser to recognize strings correctly
     even if they start with an escaped token.  [André Malo]

  *) Add fatal exception hook for use by diagnostic modules.  The hook
     is only available if the --enable-exception-hook configure parm 
     is used and the EnableExceptionHook directive has been set to 
     "on".  [Jeff Trawick]

  *) Allow mod_auth_digest to work with sub-requests with different
     methods than the original request.  PR 25040.
     [Josh Dady <jpd indecisive.com>]

     [Glenn Nielsen <glenn apache.org>]

  *) The whole codebase was relicensed and is now available under
     the Apache License, Version 2.0 (http://www.apache.org/licenses).
     [Apache Software Foundation]

  *) Fixed cache-removal order in mod_mem_cache.
     [Jean-Jacques Clar, Cliff Woolley]

  *) mod_setenvif: Fix the regex optimizer, which under circumstances
     treated the supplied regex as literal string. PR 24219.
     [André Malo]

  *) ap_mpm.h: Fix include guard of ap_mpm.h to reference mpm
     instead of mmn. [André Malo]

  *) mod_rewrite: Catch an edge case, where strange subsequent RewriteRules
     could lead to a 400 (Bad Request) response.  [André Malo]

  *) Keep focus of ITERATE and ITERATE2 on the current module when
     the module chooses to return DECLINE_CMD for the directive.
     PR 22299.  [Geoffrey Young <geoff apache.org>]

  *) Add support for IMT minor-type wildcards (e.g., text/*) to
     ExpiresByType.  PR#7991  [Ken Coar]

  *) Fix segfault in mod_mem_cache cache_insert() due to cache size
     becoming negative.  PR: 21285, 21287
     [Bill Stoddard, Massimo Torquati, Jean-Jacques Clar]

  *) core.c: If large file support is enabled, allow any file that is
     greater than AP_MAX_SENDFILE to be split into multiple buckets.
     This allows Apache to send files that are greater than 2gig.
     Otherwise we run into 32/64 bit type mismatches in the file size.
     [Brad Nicholes]

  *) proxy_http fix: mod_proxy hangs when both KeepAlive and
     ProxyErrorOverride are enabled, and a non-200 response without a
     body is generated by the backend server. (e.g.: a client makes a
