Finally, 0.2.1 is out!
This version now first time supports inworld search as well as events and should work on Joomla! 1.7 and 2.5 (it was not tested on 1.6 anymore, but should also work there)!
Due to major structure changes, 0.2.1 also requires new modules and plugins.
New also is, that the update for futuring versions now works even with the Update function inside Joomla's extension manager!
