v3.8.1

Compare Source

Highlights of the release

Scala 3.8.1 is a hotfix release for 3.8.0.
It addresses runtime regressions found after the 3.8.0 artifacts were released, specifically JVM linkage errors affecting a small subset of Scala 2 specialized types and members.

Additional regressions

The following regressions still present in 3.8.1 will be addressed in a forthcoming 3.8.2 hotfix release:

• Some for comprehensions have incorrect behavior at runtime (#​24673)
• Certain code involving calls to certain parts of the Java standard library fail to compile (#​25133)

Cautious users may wish to wait for 3.8.2.

Fixed regressions

• Revert addition of new base trait to ReturnThrowable #​24975
• Use uninlined version of Scala 2 standard-library in ScalaLibraryPlugin #​25008
• Add missing specialized method in NumericRange #​25020
• Correct the list of files to copy from Scala 2 #​25033
