Announcing Scala.js 1.0.0-M5


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

Compared to 1.0.0-M3, the main changes are:

  • 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

More details are available in the announcement on the web:

Sébastien, for the Scala.js team
