Announcing Scala.js 1.13.2

Jun 23, 2023

We are pleased to announce the release of Scala.js 1.13.2!

This release mostly contains bug fixes. It also upgrades the Scala standard library to versions 2.12.18 and 2.13.11.

Due to a deep incompatibility between sbt 1.6+ and Scala 2.12.4, we have dropped support for that particular version of Scala. Other Scala 2.12.2+ versions are still supported.

This release is the first to be built with sbt 1.9.x, which means that our sbt plugin sbt-scalajs is now dual-published on Maven Central using the legacy Ivy style and the new Maven-compliant style. The transitive dependency sbt-platform-deps is also dual-published. See the release notes of sbt 1.9.0 for more information.
