We are very excited to announce the first milestone of Scala.js 1.0.0, aka 1.0.0-M1!
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. 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 first milestone.
