Announcing Scala.js 1.0.0-M5

Aug 13, 2018

We are very excited to announce the release of Scala.js 1.0.0-M5! (there is no 1.0.0-M4)

This development release is mostly intended for testing purposes, and as a synchronization point with library authors so that they can start upgrading in preparation for the final release.

As the change in “major” version number witnesses, this release is not binary compatible with 0.6.x, nor with the previous milestones of the 1.x series. Libraries need to be recompiled and republished using this milestone to be compatible.

Moreover, this release is not entirely source compatible with 0.6.x either. We expect, however, that further milestones for 1.0.0 will stay backward source compatible with this milestone.

These release notes contain cumulative changes with respect to 0.6.24. Compared to 1.0.0-M3, the following changes are noteworthy:

  • Add support for Scala 2.13.0-M4 and its new collections
  • Overall bring up-to-date with improvements and bug fixes available in 0.6.24
  • Drop compatibility with sbt-crossproject v0.4.x and earlier (v0.5.0 or later is required)
  • java.lang.Throwable now properly extends JavaScript’s Error class (providing better stack traces in ECMAScript 2015 mode)
  • #3295 The sbt plugin does not automatically set up Java system properties from -D flags in javaOptions anymore
  • Overhaul of the linker API and the JS env API
