Currently, i try to solved some little problems with beta 1.3

But, when this version will be online in december (no specific date, as that's depending of my free time...) i will work after on a better use of joomla core functions (ACL, search...).

But as many changes in Joomla 3, i will begin this work in begin of 2013 in the same time as the version for Joomla 3.x
To modify a plugin or module to work on J3 from J2.5 is easy, but it's really more complicated for a component.
The best way will be to create an iCagenda library of functions, and not use joomla core one, but it is a lot of work (so take time...)

But as a member of joomlic, you will be informed when i will have make a planning with all the things to come !
Thanks for your patience !
