  • Require poolMaxResources to be not smaller than the number of stripes.
  • Add support for setting the number of stripes.

  • Add tryWithResource and tryTakeResource.

resource-pool-0.3.0.0 (2022-06-01)

  • Rewrite based on Control.Concurrent.QSem for better throughput and latency.
  • Make release of resources asynchronous exceptions safe.
  • Remove dependency on monad-control.
