Joomla 1.6.6 Released

The Joomla! Project is pleased to announce the immediate availability of Joomla! 1.6.6. This is a security release and is intended only for those users who are unable to use version 1.7.0. Most users should update to 1.7.0 unless there are specific reasons why they cannot use 1.7.0 at this time. Update instructions for updating from 1.6.5 to 1.6.6 are available here.

The Production Leadership Team's goal is to continue to provide regular, frequent updates to the Joomla community. Learn more about Joomla! development at the Developer Site.

Version 1.6 will reach end of life on 19 August 2011. All users of version 1.6 should update to version 1.7.0 before that time. The update process to version 1.7 is very simple, and complete instructions are available here.
