The Scala programming language continues its development within the 2.13 branch. The next release of Scala 2.13.4 includes several interesting innovations, including:
- experimental support for libraries written in Scala 3;
- Improved checking for completeness (exhaustivity) of branches when matching with a pattern. Now this check also works when using guard expressions and custom extractors;
- The default behavior of ExecutionContext has been changed (as in version 2.12).
