4.5.0.52 (recent TIM release) seems very stable except for Empower which stopped working when I upgraded from 4.5.0.37. I'm a sucker for upgrading when vendors release new versions of 4.5, but I always lose a half day fine tuning and getting all aps to work. I'm not complaining and know I don't have to step up to .55, but I'm hoping time will give us some observations on changes from .52. Any comments yet or is it too early?
