Announcing Scala.js 0.6.10

Jun 17, 2016

We are pleased to announce the release of Scala.js 0.6.10!

This release is mostly a bug-fix release. It also contains further adaptations to support the upcoming Scala 2.12.0-M5.

The most important improvement is that the sbt plugin can now generate HTML pages to run your test suites in browsers (with any testing framework), so that you can use your browser’s debugger to step through your tests.

Announcing Scala.js 0.6.8

Mar 18, 2016

We are pleased to announce the release of Scala.js 0.6.8!

This release is mostly a bugfix release. The most important changes are:

  • Fixed #2243: -jsdeps.min.js not produced anymore after upgrading from 0.6.5 to 0.6.6 and 0.6.7
  • Upgrade the implementation of the standard library to Scala 2.11.8
  • #2238 Drop support for ES6 Strong Mode

This release also contains important although invisible changes to prepare for Scala 2.12.0-M4, which will start using default methods to encode traits. This required substantial changes in Scala.js. Although most of the work was done in earlier releases of Scala.js, 0.6.8 is the first version that should be able to support Scala 2.12.0-M4.

Announcing Scala.js 0.6.6

Jan 25, 2016

We are excited to announce the release of Scala.js 0.6.6!

It has been a long while since the last release, almost 5 months already. That was too long, and we apologize. In the future, we hope never to let more than 2 months elapse between consecutive releases.

Besides bug fixes, this release brings several major improvements:

  • js.TupleN, a JS equivalent of Scala tuples
  • Support for JUnit
  • Better support of constructors of @ScalaJSDefined classes: they can now have overloads, default parameters and varargs
  • A completely redesigned internal API for the linker, whose main visible impact should be reduced memory usage and improved speed
  • js.ConstructorTag[C], a ClassTag equivalent to js.constructorOf[C]

A new website for Scala.js

Nov 23, 2015

After a couple months of design, content writing, and a lot of discussions, we are pleased to finally release our new website for Scala.js! Most if not all of the credit for this huge task goes to Otto Chrons. Big round of thanks to him!

Go and see the front page!

This new website is structured and designed specifically for front-end developers, highlighting the benefits of Scala.js over JavaScript itself, but also ECMAScript 6 or other languages targeting JavaScript, such as TypeScript.

We hope you will like it. Come and tell us in the Scala.js Gitter chat room! We would love to hear your feedback.
