0.4.10 (2023-01-27)

We’re happy to announce the release of Scala Native.

Scala Native 0.4.10 adds support for Scala 3.2.2 with its new lazy vals implementation, and drops the support for Scala 2.11 which has been EOL for over 5 years. The latest release also contains multiple bug fixes and improvements, including a new release mode scala.scalanative.build.Mode.releaseSize oriented for the size of the produced binaries.

Scala standard library used by this release is based on the following versions:

Scala binary version	Scala release
2.12	2.12.17
2.13	2.13.10
3	3.2.2
