Apache Portable Runtime 1.3.6 and APR-Utility 1.3.8 Released

   The Apache Software Foundation and the Apache Portable Runtime
   Project are proud to announce the General Availability of
   version 1.3.6 of the APR Apache Portable Runtime library, and
   version 1.3.8 of the companion APR-util Apache Portable Utility
   library.

   The corresponding version 1.2.1 of the companion APR-iconv library,
   an alternative portable implementation of the 'iconv' library,
   remains current.

   APR is available for download from:

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

   This version of APR is a primarily a bug fix release, including
   fixes for specific platforms' configuration, feature detection,
   and run time behavior.  Most developers and users are encouraged
   to adopt the latest APR 1.x version to ensure the most comprehensive
   support and access to the latest features and enhancements.

   Note that the APR-util library release 1.3.7 introduced security fixes,
   users of prior versions are strongly cautioned to upgrade to a later
   release.

   The mission of the Apache Portable Runtime Project is to create
   and maintain software libraries that provide a predictable and
   consistent interface to underlying platform-specific
   implementations. The primary goal is to provide an API to
   which software developers may code and be assured of predictable
   if not identical behavior regardless of the platform on which
   their software is built, relieving them of the need to code
   special-case conditions to work around or take advantage of
   platform-specific deficiencies or features.

   APR and its companion libraries are implemented entirely in C
   and provide a common programming interface across a wide variety
   of operating system platforms without sacrificing performance.
   Currently supported platforms include:

     UNIX variants
     Windows
     Netware
     Mac OS X
     OS/2

   To give a brief overview, the primary core
   subsystems of APR 1.3 include the following:

     Atomic operations
     Dynamic Shared Object loading
     File I/O
     Locks (mutexes, condition variables, etc)
     Memory management (high performance allocators)
     Memory-mapped files
     Multicast Sockets
     Network I/O
     Shared memory
     Thread and Process management
     Various data structures (tables, hashes, priority queues, etc)

   Users of APR 0.9 should be aware that migrating to the APR 1.x
   programming interfaces may require some adjustments; APR 1.x is
   neither source nor binary compatible with earlier APR 0.9 releases.
   Users of APR 1.x can expect consistent interfaces and binary backwards
   compatibility throughout the entire APR 1.x release cycle, as defined
   in our versioning rules:

   APR is already used extensively by the Apache HTTP Server
   version 2 and the Subversion revision control system, to
   name but a few.  We list all known projects using APR at
   http://apr.apache.org/projects.html -- so please let us know
   if you find our libraries useful in your own projects!
