sbt-mima-plugin v0.7.0 Release Notes

Release Date: 2020-02-28 // about 4 years ago

  • 🔋 Features

    • Checking generic signatures is now opt-in. #471

    Most MiMa checks (DirectMissingMethod, IncompatibleResultType, IncompatibleMethType, etc) are against the method descriptor, which is the "raw" type signature, without any information about generic parameters.
    The IncompatibleSignature check compares the Signature, which includes the full signature including generic parameters. This can catch real incompatibilities, but also sometimes triggers for a change in generics that
    ⚡️ would not in fact cause problems at run time. Notably, it will warn when updating your project to scala 2.12.9+ or 2.13.1+, see #423 ("Signature checks fail using value classes & upgrading to 2.12.9+ or 2.13.1+") for details.

    0️⃣ This check is now disabled by default. You can opt-in to it by setting:

    ThisBuild / mimaReportSignatureProblems := true
