Joomla has just released version 1.5.9 of its popular CMS. This one has codename  Vatani, as I already predicted in my post about Joomla 1.5.8. Vatani means 'nine' in Yaqui (a native American language). It's important to know that this is a security release. You should always upgrade when there is a new release, but for a security release this is even more imporant. So don't postpone and start your update today.

Two issues that could be exploited by hackers are fixed in this release. That's not the only change as this release contains no less then 81 fixed issues. The full release notes and links to the new packages can be found in the Joomla announcements.
