Further info on this vulnerability:
So, those with high security needs might want to start using this version right away. The downsides are that there's a higher likelihood of some major bugs that haven't been found yet (including bugs that may compromise anonymity or security), since there are some real software changes in this version (from 2.0 > 2.2). If you do find any bugs, please be sure to report them on the Tails Bug Tracker.
Are you implying 2.0.1 did not address this? 0.o
