The Joomla! Project and the Production Leadership Team are proud to announce the release of Joomla! 3.3.1. This is a maintenance release for the 3.x series of the Joomla! CMS.
If you are currently running a Joomla! release on a server with PHP 5.3.10 or later, we encourage you to update immediately to Joomla! 3.3.1 via either the one-click update or the update downloads available at http://www.joomla.org/download.html.
Note that in order to update directly to 3.3.1 via the core update component, you must be running 3.2.2 or later due to the raised minimum supported PHP version and the update system not supporting checking the server’s PHP version in older releases. Older 3.x releases will be prompted to update to 3.2.4 before being presented the 3.3.1 update.
