Announcing Scala.js 0.6.7

Feb 12, 2016.

We are pleased to announce the release of Scala.js 0.6.7!

This release is almost exclusively a bugfix release, after some critical regressions regarding the sbt plugin in Scala.js 0.6.6. In particular, it fixes:

  • #2195 Source maps to the Scala standard library are broken
  • #2198 “Illegal classpath entry: " after upgrading from 0.6.5 to 0.6.6
  • #2202 and #2219 NullPointerException or AssertionError while linking in client/server projects
  • #2222 Huge performance regression of the optimizer

Besides bug fixes, this release brings a few improvements:

  • js.Promise and its conversions to/from Future
  • Proper stack traces for Throwables in Node.js
  • Support for Scala cross-version source directories in shared/

Release notes

If upgrading from 0.6.5 or earlier, please also read the release notes of 0.6.6, which contains some breaking changes.

As a minor release, 0.6.7 is backward source and binary compatible with previous releases in the 0.6.x series. Libraries compiled with earlier versions can be used with 0.6.7 without change. 0.6.7 is also forward binary compatible with 0.6.6, but not with earlier releases: libraries compiled with 0.6.7 cannot be used by projects using 0.6.{0-5}.

Please report any issues on GitHub.

Bug fixes

In addition to the important bug fixes mentioned above, the following bugs have been fixed:

  • #2228 BigInt("+100000000") crashes
  • #2220 Compiler crash in 2.12 with a lambda inside a Scala.js-defined JS class
  • #2217 this["require"]() and fastOptJS
  • #2197 @JSName fails for field in trait
