The Apache Software Foundation and the Apache HTTP Server Project are
   pleased to announce the release of version 2.2.13 of the Apache HTTP
   Server ("Apache").  This version of Apache is principally a security
   and bug fix release.  Notably, this version bundles the APR Library
   version 1.3.8 and APR Utility Library version 1.3.9, which address
   a security concern which may be triggered by some third party modules.

   We consider this release to be the best version of Apache available, and
   encourage users of all prior versions to upgrade.

   Apache HTTP Server 2.2.13 is available for download from:

     http://httpd.apache.org/download.cgi

   Apache 2.2 offers numerous enhancements, improvements, and performance
   boosts over the 2.0 codebase.  For an overview of new features
   introduced since 2.0 please see:

     http://httpd.apache.org/docs/2.2/new_features_2_2.html

   Please see the CHANGES_2.2 file, linked from the download page, for a
   full list of changes.  A condensed list, CHANGES_2.2.13 provides the
   complete list of changes since 2.2.12. A summary of security
   vulnerabilities which were addressed in the previous 2.2.12 and earlier
   releases is available:

     http://httpd.apache.org/security/vulnerabilities_22.html

   Apache HTTP Server 1.3.41 and 2.0.63 legacy releases are also currently
   available.  See the appropriate CHANGES from the url above.  See the
   corresponding CHANGES files linked from the download page.  The Apache
   HTTP Project developers strongly encourage all users to migrate to
   Apache 2.2, as only limited maintenance is performed on these legacy
   versions.

   This release includes the Apache Portable Runtime (APR) version 1.3.8
   bundled with the tar and zip distributions.  The APR libraries libapr
   and libaprutil (and on Win32, libapriconv) must all be updated to ensure
   binary compatibility and address many known security and platform bugs.

   This release builds on and extends the Apache 2.0 API.  Modules written
   for Apache 2.0 will need to be recompiled in order to run with Apache
   2.2, and require minimal or no source code changes.

   When upgrading or installing this version of Apache, please bear in mind
   that if you intend to use Apache with one of the threaded MPMs (other
   than the Prefork MPM), you must ensure that any modules you will be
   using (and the libraries they depend on) are thread-safe.
