The Android Facebook app has just been updated on 8/29/2012.
What's in this version:
Fixes a crash affecting some users
Reviews claim the app is now worse than ever, crashes, force closes, freezes, loads slowwwww.
Personally, I normally use the mobile site, rarely use the Facebook App, and never ever update to app.
