Re: Is downgrade from 0.96.0 to 0.94.6 possible?
FYI you'll be in the same situation with 0.95.2, actually worse since it's
really just a developer preview release.

But if you meant "try" in its strict sense, ie use it on a test cluster,
then yes please do. The more people we get to try it out the better 0.96.0
will be.
