Joomla! 1.5.17 released
The Joomla! project has released version 1.5.17, containing several security fixes. After you use Akeeba Backup (also known as JoomlaPack) to create a backup, make sure to use Sam’s Update Manager to update the Joomla! websites you manage to this new version. If you are busy, Open Source Support Desk wouldn’t mind doing the Joomla! updating for you.
We just published a blog on how to update a Joomla! 1.5 website, have a look at it here.
