Changelog of @hackage/machinecell 4.0.0

4.0.0

Breaking changes of APIs

• Side-effects are represented by Monads rather than ArrowApplyies.
  • Replace the base arrow ProcessA with ProcessT
  • ProcessA is now type alias for compatibility
  • Change the signatures of construction functions
    • constructT, repeatedlyT
    • construct, repeatedly
  • Change the signatures of running functions
    • runT, runT_, run, run_
    • stepRun, stepYield
      • Delete ExecInfo.
• Change the Occasional' type class
  • Add method burst
  • Move noEvent end out of the type class

Additions

• Add ZeroEvent. Change the signatures of blocking sources with it.
• Add Evolution
• Add type classes MonadAwait, MonadYield, MonadStop
  • Generalize await, yield, and stop to Evolution
• Add fire, fire0

3.3.2

3.3.1

• Modify the versions of depending packages.

3.3.0

• Correct a space leak problem
• Add splitEvent, oneshot
