The Joomla Team announces the immediate availability of Joomla 1.5.18. This version inludes a security fix as well as a roll-back for the plugin auto disable feature, which was introduced in version 1.5.16 but did not satisfy the community at all.
As this update includes a security fix everyone is encouraged to upgrade immediately!
