    🚀 Release notes

    🚀 There are a significant number of breaking changes in this release:

    • 📚 Ringpop constructor has been renamed from Ringpop.NewRingpop to ringpop.New(app string, opts ...Option) and now accepts optional functional arguments. See the package documentation for a list of options.
    • 🚚 ringpop.Bootstrap now accepts swim.BootstrapOptions. ringpop.BootstrapOptions has been removed.
    • Many public methods now return an error if they are called before the ring is bootstrapped. Signatures for the changed methods are:
      • Bootstrap(opts *swim.BootstrapOptions) ([]string, error)
      • Checksum() (uint32, error)
      • Lookup(key string) (string, error)
      • LookupN(key string, n int) ([]string, error)
      • Uptime() (time.Duration, error)
      • WhoAmI() (string, error)
    • ✂ Removed public method ringpop.Destroyed(). Use the new ringpop.Ready() to determine if the ring is ready or not.
    • 📦 Events moved to ringpop.events package. This includes:
      • EventListener
      • RingChangedEvent
      • RingChecksumEvent
      • LookupEvent
    • The behaviour of creating a single-node cluster has changed. Calling Bootstrap() with no bootstrap file or hosts will now cause Ringpop to create a single-node cluster.
