ZIO v1.0.0-RC17 Release Notes

Release Date: 2019-11-18 // over 4 years ago

  • Notable changes

    🚀 This release contains major changes related to how fiber supervision is working.
    The new behavior is that a fiber will automatically be interrupted when its parent fiber is interrupted. To make forked fibers independent of their parents, use .daemon.
    🚚 Previously existing interruptChildren, supervised, unsupervised, checkSupervised, superviseStatus have been removed in favor of daemon, nonDaemon, checkDaemon and daemonStatus.

    • Complete overhaul of supervision (#2169) by @jdegoes
    • ➕ Add fiber dumps with pretty printing for easier diagnostics (#2228) by @jdegoes
    • ➕ Add a new implicit instance CanFail[E] which provides implicit evidence that an effect with an error type E can fail, that is that E is not equal to Nothing. Requires such evidence to exist for ZIO combinators such as orElse that only make sense if an effect can fail (#2049) by @adamgfraser
    • Similarly, implements NeedsEnv so that useless combinators involving effects that don't require an environment don't compile (#2065) by @adamgfraser
    • ➕ Add ZIO.fromFunctionFuture (#1961) by @jczuchnowski
    • effectAsync should not resume fiber twice after interruption (#1939) by @darl
    • ➕ Add withFilter (#2114) by @wi101
    • 👉 Use URIO in type signatures where possible (#2092) by @joroKr21
    • ➕ Add ZIO#doUntil and ZIO#doWhile (#2147) by @adamgfraser
    • Ignore should not recover from unchecked exceptions (#2148) by @alexvanolst
    • 🐎 Reimplement RaceWith in the ZIO runloop for better performance (#2091) by @YuvalItzchakov
    • Adapt ZIO.someOrFailException to improve interop with error types (#2087) by @mlangc
    • 🛠 Fix Cause Definition of Equals and HashCode (#2220) by @adamgfraser
    • 👌 Improve implementation of InterruptStatus#isInterruptible (#2188) by @sirthias
