Today the Joomla! team released another update to 1.5. Wojmamni Ama Woi, Yaqui for 12, comes with a few bug fixes and three moderate-level security fixes. We encourage you to update your installation, of course, and we'll make sure that our templates and extensions don't have any problems with the new version. If you do run into anything, though, be sure to let us know.

Download the entire package of 1.5.12 or an upgrade from the Joomla.org website.
