Announcing Scala.js 1.17.0

Sep 28, 2024

We are excited to announce the release of Scala.js 1.17.0!

This release comes with a brand new, shiny, experimental WebAssembly backend. You can now, under certain conditions, take your existing Scala.js application and compile it to WebAssembly instead.

There were also some bug fixes. Despite the abnormally long release cycle (v1.16.0 was released 6 months ago), the only external bug report came in 3 weeks ago. As far as we can tell, nobody was blocked waiting for a bugfix for this long.

Announcing Scala.js 1.16.0

Mar 19, 2024

We are excited to announce the release of Scala.js 1.16.0!

The biggest highlight of this release is that we added a Scala.js-specific minifier. When combined with a general-purpose JavaScript minifier, our minifier should bring most of the code size benefits of the Google Closure Compiler when the latter cannot be enabled, notably when emitting ECMAScript modules.

Scala.js 1.16.0 also upgrades by default to the standard library of Scala 2.12.19 and 2.13.13.

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.
