On july, 22nd, the PHP Group released PHP 5.2.14 :
The PHP development team would like to announce the immediate availability of PHP 5.2.14. This release focuses on improving the stability of the PHP 5.2.x branch with over 60 bug fixes, some of which are security related.
This release marks the end of the active support for PHP 5.2. Following this release the PHP 5.2 series will receive no further active bug maintenance. Security fixes for PHP 5.2 might be published on a case by cases basis. All users of PHP 5.2 are encouraged to upgrade to PHP 5.3.
The packages for Debian “Lenny” are now available on Dotdeb.
Thanks (again) to Stefan Esser and the Month of PHP security for improving PHP.
