Anything Digital released JCalPro for Joomla 1.5 (native) and it includes for the first time plugins to accompany the component and modules.

The Search plugin allows JCal Pro events to be returned in the Joomla! search results or even using the Advanced Search extension. The Latest Events plugin makes it easy to add a dynamic list of upcoming events to content items. This is very useful in places where a module is not appropriate or if you want a certain category of upcoming events to be indexed by Google.

They also published a small maintenance release of JCal Pro recently to version 1.5.3.2 'Stable' to fix some annoying bug. As always, this version is exclusive for Joomla 1.0.x.
