Kotlin Compatibility

The Kotlin compiler plugin API is not a stable API, so not every version of Metro will work with every version of the Kotlin compiler.

Starting with Metro 0.6.9, Metro tries to support forward compatibility on a best-effort basis. Some releases may introduce prohibitively difficult breaking changes that require companion release, so check Metro’s open PRs for one targeting that Kotlin version for details.

Kotlin version	Metro versions (inclusive)
2.3.0	0.6.9 -
2.2.20	0.6.6 -
2.2.10	0.4.0 - 0.6.5
2.2.0	0.4.0 - 0.6.5
2.1.21	0.3.1 - 0.3.8
2.1.20	0.1.2 - 0.3.0
