The Apache Software Foundation and the Apache Portable Runtime Project are proud to announce the General Availability of version 1.5.4 of the Apache Portable Runtime Utility library.
APR-util 1.5.4 is a bug fix release, resolving several run-time problems as well as several build problems. See CHANGES-APR-UTIL-1.5 for more information.
Version 1.5.1 of the Apache Portable Runtime library remains current.
Version 1.2.1 of the companion APR-iconv library, an alternative portable implementation of the 'iconv' library, remains current.
As announced previously, the 0.9.x branches of Apache Portable Runtime library, Apache Portable Runtime Utility library, and the companion APR-iconv library have been retired. No further bug or security fixes will be available for these branches.
APR is available for download from:
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:
To give a brief overview, the primary core subsystems of APR 1.x include the following:

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!
