05 October 2005 - Apache Portable Runtime 0.9.7 Released
The Apache Software Foundation and the Apache Portable Runtime Project are proud to announce the General Availability of version 0.9.7 of the Apache Portable Runtime, APR, and version 0.9.7 of it's companion project, the Apache Portable Utility library APR-util. A corresponding version of APR-iconv 0.9.7, an alternative portable implementation of the 'iconv' library, is released for users without a system iconv implementation.
APR is available for download from:
http://apr.apache.org/download.cgi
This version of APR is principally a bug fix release, and is provided only for users requiring APR 0.9 compatibility. Most users are recommended to adopt the latest APR 1.x version to ensure the most comprehensive support access to the latest features and enhancements.
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
- Windows
- Netware
- Mac OS X
- OS/2
- BeOS
To give a brief overview, the primary core subsystems of APR 0.9 include the following:
- Atomic operations
- Dynamic Shared Object management
- File I/O
- Locks (mutexes, condition variables, etc)
- Memory management (high performance allocators)
- Memory-mapped files
- Network I/O
- Shared memory
- Thread and Process management
- Various data structures (tables, hashes, priority queues, etc)
For a more complete list, please refer to the following URLs:

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 not binary compatible with earlier APR 0.9 releases. Users of APR 1.x can expect consistent interfaces and binary backwards compatibility through the entire APR 1.x release cycle, as defined in our versioning rules:
http://apr.apache.org/versioning.html
APR is already used extensively by the Apache HTTP Server version 2.0 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.
