The PHP Group has officially released the latest version of the PHP 4.4.x series - version 4.4.8 (mostly security fixes) - also the final release of the PHP 4.4.x series.
The PHP development team would like to announce the immediate availability of PHP 4.4.8. It continues to improve the security and the stability of the 4.4 branch and all users are strongly encouraged to upgrade to it as soon as possible. This release wraps up all the outstanding patches for the PHP 4.4 series, and is therefore the last normal PHP 4.4 release. If necessary, releases to address security issues could be made until 2008-08-08.
Among the issues corrected are things with chunk_split, an overflow in str[c]spn, regression in glob with open_basedir and correcting the INIFILE LOCAL option. Check out the Changelog for a full list of changes.
