We are thrilled to announce the General Availability release of Scala.js 1.0.0!

Scala.js is a close dialect of Scala compiling to JavaScript, featuring great portability wrt. Scala/JVM, interoperability with JavaScript, and performance.

After 7 years of development, including 5 years of stability within the 0.6.x series, we are finally ready to present Scala.js 1.0.0. Quoting Antoine de Saint-Exupéry,

Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.

Scala.js 1.0.0 is the culmination of our efforts to simplify, specify, and future-proof all aspects of Scala.js, from the language semantics to the internal APIs, so that there is nothing left to take away.

As the change in major version number witnesses, this release is not binary compatible with 0.6.x, nor with the previous milestones and RCs of the 1.x series. Libraries need to be recompiled and republished using Scala.js 1.0.0 to be compatible. Several libraries at the core of the Scala/Scala.js ecosystem have already been published and are available for Scala.js 1.0.0. Here is a list of libraries known to support Scala.js 1.x.

Moreover, this release is not entirely source compatible with 0.6.x either (see Breaking Changes below).

Here are some highlights of Scala.js 1.0.0:

• Better interoperability with JavaScript libraries (see the Enhancements section below)
• Improved portability with respect to Scala/JVM
• Better run-time performance
