The Apache Software Foundation and the Apache HTTP Server Project are pleased to announce the release of version 2.2.4 of the Apache HTTP Server ("Apache"). This version of Apache is principally a bugfix release.
We consider this release to be the best version of Apache available, and encourage users of all prior versions to upgrade.
Apache HTTP Server 2.2.4 is available for download from:
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:
Please see the CHANGES_2.2 file, linked from the download page, for a full list of changes. A summary of security vulnerabilities which were addressed in the previous 2.2.3 and earlier releases is available:
Apache HTTP Server 1.3.37 and 2.0.59 legacy releases are also currently available. 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 for these legacy releases.
This release includes the Apache Portable Runtime (APR) version 1.2.8 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 platform bugs.
This release builds on and extends the Apache 2.0 API. Modules written for Apache version 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.
