Please note we use the following labels for automated release descriptions:

  • chore if your PR does not change any types and runtime semantics
  • fix if your PR merely fixes incorrect behavior


We have an automated check for style conformance. You can run sbt checkfmt before PR. If you have any trouble during this check, just run sbt fmt and commit again.
