I know of a couple of issues with the 'Latest Events module' when dealing with events that span multiple days. These simple issues should really have been sorted out a long time ago, they shouldn't have needed any attention being drawn to them on the forums. Who knows how long it will take to see a new release.
I do really like JCal Pro and really like how it looks, they did a good job with the new release, but the development of it is always a concern.
More attention is focused on Anything Digital's other extensions like sh404sef.
My hopes for the future would be that we see more maintenance and feature releases in the coming months and years for JCalPro. Continued releases are really needed by JCal customers.
