We've been working hard on it. CL 12 was scheduled for June 2012... some of Calculate users have even been counting the days left; the very same, I guess, would be counting the delay. But we're convinced that better late than badly done!
Thus, we're announcing the beta testing release today. Enjoy, and tell us about the bugs whenever you come across any. We always appreciate your contribution, so feel free to share your impressions.
Please have a look at the new Calculate Utilities 3. They were and still are meant to become the killer feature of the final release:

(The general appearance was slightly rebranded, too. But this is not much of a feature, this is just a nice addition, or so we hope.)
