Software Update: Apache 2.2.0

The Apache HTTP Server Project development team has released a new version of their Apache HTTP server. This web server is used on many platforms and can be provided with all kinds of functionalities using modules. The version number arrived at 2.2.0 with the following announcement:

The Apache Software Foundation and The Apache HTTP Server Project are pleased to announce the release of version 2.2.0 of the Apache HTTP Server (“Apache”). We consider this release to be the best version of Apache available, and encourage users of all prior versions to upgrade.

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 this page.

This release includes the Apache Portable Runtime (APR) version 1.2.2 bundled with the tar and zip distributions. The APR libraries libapr, libaprutil, and (on Win32) libapriconv must all be updated to ensure binary compatibility and address many known platform bugs.

This release has been through extensive testing, including live at some of the world’s busiest sites, and is now considered stable. This means that modules and applications developed for Apache 2.2.0 will be both source- and binary-compatible with future 2.2.x releases. This release builds on and extends the Apache 2.0 API. Modules written for Apache 2.0 will need to be recompiled in order to run with Apache 2.2, but no substantial reworking should be necessary.

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, you must ensure that any modules you will be using (and the libraries they depend on) are thread-safe.
