1.30.0

Notable Changes

Added

• Nexus operation link propagation for signals. When a Nexus operation handler signals a workflow
  (including signal-with-start), the inbound Nexus request links are now forwarded onto the signaled
  workflow so its history events link back to the caller, and the link the server returns for the
  signaled event is attached to the caller workflow's Nexus operation history event. This makes the
  caller and callee mutually navigable in the UI for signal-based Nexus operations.
• Exposed backoff_start_interval for continue-as-new, to allow the new workflow to start after a delay.

Changed

• AWS Lambda worker configure parameter supports sync, async, and async
  generator style functions. This callback is invoked on the asyncio event
  loop.
• Relaxed the protobuf dependency bounds to allow protobuf 7 where compatible
  with the selected optional dependencies.
• Standalone Nexus operation links are now forwarded on start workflow and signal requests.

Breaking Changes

• AWS Lambda worker configure parameter has been changed to be invoked
  per-invocation of the worker instead of only at startup. It is advised that
  any shared, heavy-weight operations are performed outside of the callback
  before run_worker is invoked.
