Release Notes

Feature Highlights

  • Refinements on the existing API. This represents the majority of API changes that need to be made before freezing the API for 1.0.
  • The backend and synchronizer have been mostly rewritten. They now no longer wait until the proposal window finishes if all running match functions finish early. Additionally they have better error handling, and optimistically stream data.
  • Revamped Grafana dashboards with detailed metrics documentation.
  • Have started end to end scale testing. Early results were presented in the January Community Meeting. Some minor issues have been discovered and fixed as a result.
  • New ReleaseTickets API on the BackendService to release ticket back to the pending tickets pool from the ignore list @caleb #1059
