Two-twelve-twenty fades, out it goes,
Twenty-one arrives, fresh and spry,
Scala builds faster, reaching the sky! ✨

.github/workflows/ci.yml (2)

26-26: LGTM! Matrix version updated correctly.

The Scala version in the build matrix has been correctly updated to 2.12.21. The CI workflow includes a validation step (line 55) that ensures the workflow file is properly synchronized with the build.sbt configuration.

---

107-115: LGTM! Artifact handling updated consistently.

The artifact download and inflate steps have been correctly updated to reference 2.12.21, maintaining consistency with the build matrix version.

build.sbt (1)

2-2: LGTM! Scala version bumped to 2.12.21.

The patch version update is correctly applied and will propagate through crossScalaVersions (line 8). Scala patch releases maintain backward compatibility, so this should be a safe update.
