v4.0.0-rc.1

This pre-release for version v4.0.0 features a revamped API for writing more expressive asynchronous programs with stronger guarantees.

• Fiber cooperative multi-tasking primitive for fork/join workflows
• Stronger cleanup guarantees with bracket and supervise.
• Reformulated AVar semantics

Migration Notes

• The low-level callback representation is no longer relevant. If you've defined Aff effects via the FFI, you should transition to using Control.Monad.Eff.Compat, which provides an EffFn adapter.
• The AVar API methods have changed to match Haskell's MVar API. putVar effects now block until matched with a takeVar. It's possible to recover similar behavior as the old API with forkAff (try (putVar avar value)).
• Several unlawful instances where removed for Aff (Alternative, MonadPlus, and MonadZero).
