v0.4.0

Breaking changes

• Due to some breaking changes to the storage format, we recommend existing users to start with a new cluster and wipe all existing state.
• We've updated the default ports allocation, to reduce potential conflicts with other commonly used tools. See https://docs.restate.dev/restate/deployment.
• We've simplified the definition of Protobuf service contracts for event handlers. See https://docs.restate.dev/services/sdk/kafka.
• Introduced non-backward compatible change in the built-in service dev.restate.Ingress. See https://github.com/restatedev/proto/blob/main/dev/restate/services.proto.
• This release works only with sdk-typescript >= 0.3.1

New features

• You can now provide an idempotency key when sending requests to Restate from an external client. This allows to implement end-to-end exactly once processing of requests. See https://docs.restate.dev/services/invocation#invoke-a-service-idempotently.
• The introspection SQL interface has been expanded with two new tables:
  • sys_invocation_state to inspect the status of in-flight invocations.
  • sys_journal to inspect the invocation journal.
• External ingress invocation traces now have client socket info

Among the other changes, we've also included a plethora of bug fixes and small improvements.

Enjoy!
