Its pretty stable for such an early release.
There are of course some bugs, as well as some app incompatibilities, but thats to be expected.
Been using it since day one, few minor issues, and found one major issue using the app battery widget reborn, and then setting its notification to the highest setting. It would cause system UI to crash constantly. After messing around, and then adjusting it down from highest, its been fine again.
No April update for it yet, but hopefully soon.
