0.4.17 (2024-01-19)

We’re happy to announce the release of Scala Native 0.4.17, which is the next maintance release. The new version introduces support for the Scala 3.4.0 and fixes some of found bugs.

Compatibility notes

Due to the limitations of versions 0.4.x the Scala 3 Standard Library NIR outputs are based on Scala 3.3.0. Any runtime usage of methods introduced to Scala 3 standard library after 3.3.0 would not work and would result in linking error. Compile time only methods like macros or mirrors would still work. This issue would be handled in Scala Native 0.5.x by using a different publishing strategy.

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

Scala binary version Scala release
2.12 2.12.18
2.13 2.13.12
3 3.3.0
