The PHP development team would like to announce the immediate availability of PHP 5.4.5. This release fixes over 30 bugs and includes a fix for a security related overflow issue in the stream implementation. All users of PHP are encouraged to upgrade to PHP 5.4.5
Changes that affect compatibility:
Extensions moved to PECL:
PHP 5.4 series will be the last versions to support Windows XP and Windows 2003. We will not provide binary packages for these Windows versions anymore after PHP 5.4.
For users upgrading from PHP 5.3 there is a migration guide available here, detailing the changes between those releases and PHP 5.4.x.
For a full list of changes in PHP 5.4.x, see the ChangeLog.
