PHP Version 5.2.3 Released

PHP version 5.2.3 has been released. This release continues to improve the security and the stability of the 5.X branch and all users are strongly encouraged to upgrade.

The PHP development team would like to announce the immediate availability of PHP 5.2.3. This release continues to improve the security and the stability of the 5.X branch as well as addressing two regressions introduced by the previous 5.2 releases.
