Both updates fix a problem with the clouds layer not updating. The Android update also adds compatibility for Android 5 / Lollipop.
Also, Catfood Earth for Android is now free. I had been charging $0.99 for the Android version but I've reached the conclusion that I'm never going to retire based on this (or even buy more than a couple of beers) so it's not worth the hassle. Catfood Earth for Windows has been free since 3.20.
