Apache HTTP Server 2.3.8-alpha 2010-08-31

The Apache HTTP Server Project is pleased to announce the release of Apache HTTP Server, version 2.3.8-alpha. This version of httpd is principally an alpha release to test new technology and features that are incompatible or too large for the stable 2.2.x branch. This alpha release should not be presumed to be compatible with binaries built against any prior or future version.

This release is expected to be the last alpha release; subsequent releases will be beta releases as we move towards 2.4.0-GA.
