This is a very stable library with very small surface area, so I think we're basically going to be fine aggressively moving towards a psychologically "safe" number. It's been tested extensively in Cats Effect, so I don't think we should have any concerns about instability in the implementation.

Cats Effect will want a 1.0.0 release before we're comfortable doing 3.3.0, which will probably happen within about 1-2 months, so I would like it if we could live within that kind of time frame.

IMO we should release an 0.2.0 once @armanbilge runs out of ideas of things to change. ;-) Then let that bake for as long as we feel like, then do a 1.0.0. Process-wise, it'd be great to get @sjrd's blessing on this before we cut 1.0.0.
