Only about 3 days ago, the Joomla! Core Team released Joomla! version 1.5.16. Unfortunately, 3 bugs slipped into the package, making the package inoperative on some systems. For this reason, a new version was now released with version 1.5.17.

We recommend you to implement this update straight away, especially if you have not updated to version 1.5.16 yet, as this version closed some security gaps that your clients and you wouldn’t want to have in your Joomla! ;-) Further information on the Joomla! update can be found on the Joomla! main page.

So don't forget to update!
Your Yagendoo team
