I'm currently working on 2.1.7, with New Google map script in admin (easy way to add address, and faster as auto-field of country and locality!), some fix, new date format system (with globalization, to have date format in each culture available in iCagenda), integration language and access in front-end for events...
In the months to come, and each version, i will add features, and try to make it more and more easy to use ! So, that mean recurring events with start and end time, and with days options.
