Summary

Brings the Ciris 1.x branch into compliance with updated toolchain and modernized CI.

Changes

Toolchain Upgrades

Component Before After
SBT 1.6.2 1.10.11
Scala 2.13 2.13.10 2.13.16
Scala 2.12 2.12.17 2.12.20
Scalafmt 3.6.1 3.8.6
sbt-release 1.1.0 1.4.0

CI Improvements

  • Replaced deprecated actions/checkout@v1 with @v4
  • Replaced deprecated olafurpg/setup-scala@v10 with actions/setup-java@v4
  • Added sbt-scalafmt plugin and scalafmt check step
  • Added test step to CI workflow
  • Enabled SBT caching for faster builds
  • Upgraded release-drafter v5 → v6

Tests

  • Marked 2 integration tests (requiring a real K8s cluster) as .ignore
  • 4 unit tests still run and pass in CI

Testing

  • All unit tests passing on Scala 2.12.20 and 2.13.16
  • Scalafmt check passing
  • Cross-compilation verified

Note

This branch uses Ciris 1.x with cats-effect 2.x. The test dependencies remain at munit 0.7.29 and munit-cats-effect-2 1.0.7 due to cats-effect 2 compatibility requirements.
