From Lithoglyphics, the blog of my company:
We have just released LadyBugz 1.6.6, available from our website and through auto update.
After we released LadyBugz 1.6.1, we have received a number of bug reports that it crashed at various places. We realized that our garbage collection transition was not completely done, and there were loose ends that we overlooked. We take those issues seriously, and after a week of testing, we believe 1.6.6 should behave way better.
I have written previously why we chose to go back from garbage collection to manual memory management, and while it was absolutely necessary, I really wish we could have found the crashing bugs earlier with a broader range of testing data set. Quitting the perks of garbage collection is a hard process (not having to worry about complex object relationship and ownership is especially addictive), and hard-to-reproduce crashing bugs suck. We have learned a thing or two the hard way.
