The mission of the Apache Portable Runtime (APR) 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 behaviour 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.

The Apache Portable Runtime Project is proud to announce the release of APR version 1.2.8. For details of this release, see the official announcement as well as the CHANGES-APR-1.2, CHANGES-APR-UTIL-1.2, and CHANGES-APR-ICONV-1.1 files.

After several years of development, APR is beginning to see use outside of the Apache HTTP Server. To encourage more people to investigate APR for their projects, here are a list of both Open Source and Commercial projects that are currently using APR. If you are using APR, and would like your project recognized, please send e-mail to the developer's mailing list.

The following is a list of supported development projects under the APR Project. All of the development happens on the indicated mailing lists. See mailing lists to learn how to take part in these discussions. Or, check the archives.
