Announcing Scala 3.1.0-RC2

Scala 3.1.0-RC2 is ready for testing.
The main goal of this release was to change the reference version of the compiler used in the bootstrapping process. It is no longer the nightly build.
Also, we have backported fixes for two issues:

  • Irreducible match types not raising errors (#12768)
  • Completions sometimes causing AssertionErrors (#13530).
