Release Notes

scala/scala (org.scala-lang:scala-library)

v2.13.9: Scala 2.13.9

The following changes are highlights of this release:

Regression

Library maintainers should avoid publishing libraries using Scala 2.13.9. Please use 2.13.10 instead. 2.13.9 has a regression where binary-incompatible bytecode is emitted for case classes which are also value classes (case class ... extends AnyVal).
