SlideDeck 2.1.20121115 is out. This version addresses a couple of nasty bugs that were introduced in 2.1.20121101 and 2.1.20121102.
We've also added some new features! You can now purchase premium lenses, and the WordPress Posts source now allows you to choose the specific image size (if you need it).
