Joomla 1.5.11 has been released. This is a security release and users are strongly encouraged to upgrade immediately. An additional patch to resolve a formatting problem in the administrator panel has also been released.

Less than 12 hours after it's release, all customers on Abivia application support plans have been upgraded to the latest version (including the patch). Security exploits are likely to emerge quite quickly. Customers without support plans are advised to upgrade their installations as soon as possible.

All 1.5.11 release packages can be found on the Joomlacode site.
