5. RIO will be alpha quality (in terms of features and
functionality) when it releases with 4.0, it is a tech preview to get
feedback from the community.
6. RIO is not a blocker for releasing 4.0, so if said alpha tasks
are not met, it may not be part of 4.0 as well
Hope this clarifies volume compatibility concerns from a distribute
layer perspective in 4.0.
