We are thrilled to announce the release of Scala.js 0.6.5!

This is probably the most important release since Scala.js 0.5.0! It brings significant advances to interoperability with JavaScript:

• You can now implement subclasses of JavaScript classes and traits in Scala.js!
• Using the same semantics, you can now define object literals with new js.Object { val x = 5 }
• There is a new unboxed pseudo-union type A | B to more accurately type your JavaScript facades
• You can statically typecheck that the @JSExports of a Scala class comply with a JavaScript facade trait with js.use(x).as[T]

We are excited to announce the release of Scala.js 0.6.3!

A lot has happened in this release, probably because we dragged it for a longer amount of time than usual (2 months since the last release!). Besides the usual bag of bug fixes, there are three highlights:

• Support for BigInteger and BigDecimal, thanks to an incredible amount of work by @InTheNow.
• Extension of jsDependencies to specify minified versions of the JS libraries.
• Experimental output modes to target ECMAScript 6, as well as Strong Mode.

We also welcome Nicolas Stucki aka @nicolasstucki to the core team at EPFL.

We are excited to announce the release of Scala.js 0.6.2!

This release mostly contains bug fixes, among which the lack of support of java.net.URI for Unicode characters. It also brings code size reduction and performance improvements to fastOpt code (although nothing changes in fullOpt).

We are also happy to share that Scala.js is now part of Scala’s community build.

We are thrilled to announce the final release of Scala.js 0.6.0!

As of this version, we do not consider Scala.js to be experimental anymore. We believe it has reached maturity, and from now on, the language semantics as well as the APIs will only evolve in backward compatible ways, or go through proper deprecation cycles.

Today is also the 2-year anniversary of Scala.js! The first commit was pushed on February 5, 2013.
