We expect this to be the last major release before cats-effect 1.0, which will target cats-core 1.0 when it is released. There really aren't any major changes left to be made, and stability is a major goal going forward.

EffectLawshave been moved up toSyncLaws. This strengthens the requirements on effects which implementSyncbut not `Effect - Removed
Kleisliinductive instances (because of typelevel/cats#1733) - Added a law governing the error propagation behavior of
Effect#runAsync - Bumped cats-core dependency to 1.0.0-MF
