    🚀 Release notes

    Identity Carry Over

    🔧 Identity carry over provides a way to manually configure the identity of a member on the hashring. 🚀 By changing the identity to be something else than its address, it becomes possible to guarantee ring equality before and after deploys in a dynamic environment (e.g. mesos).

    Self Eviction

    By calling ringpop.SelfEvict on shutdown, a member will declare itself as faulty and gossips this to the other members. 🚚 This removes the time window where it would be marked as suspect; in this way removing the time where other members considered it to be part of the ring while it was not responding anymore.

    💥 Breaking change to the identity-option

    Prior to ringpop v0.8.0 the address was used as the identity of a member. Starting with version v0.8.0, it's possible to 🔧 configure a separate identity. As a result, the behaviour of the Identity and IdentityResolverFunc has been changed. 🔧 The Identity option now configures the identity of a member and will return an error when it matches an ip:port; services that were using Identity or IdentityResolverFunc should now use the Address and AddressResolverFunc options. 🔨 You could use the following gofmt snippets to easily refactor:

    gofmt -r 'ringpop.Identity(a) -> ringpop.Address(a)' -w .
gofmt -r 'ringpop.IdentityResolverFunc(a) -> ringpop.AddressResolverFunc(a)' -w .
