We are pleased to announce the release of Scala.js 0.6.25!

This release brings support for Scala 2.13.0-M5, as well as jsdom v12.x. It also fixes a number of issues.

Read on for more details.

Getting started

If you are new to Scala.js, head over to the tutorial.

Release notes

If you use .scala build files in project/ and are upgrading from Scala.js 0.6.22 or earlier, do read the release notes of 0.6.23, which contain a source breaking change in that situation.

If upgrading from Scala.js 0.6.14 or earlier, make sure to read the release notes of 0.6.15, which contain important migration information.

As a minor release, 0.6.25 is backward binary compatible with previous releases in the 0.6.x series. Libraries compiled with earlier versions can be used with 0.6.25 without change. 0.6.25 is also forward binary compatible with 0.6.{17-24}, but not with earlier releases: libraries compiled with 0.6.25 cannot be used by projects using 0.6.{0-16}.

Please report any issues on GitHub.

Bug fixes

Among others, the following bugs have been fixed in 0.6.25:

• #3426 and #3422 lazy vals within non-native JS classes are now supported
  • Caveat: override lazy vals do not behave correctly when they override another lazy val. This issue is not fixable in 0.6.x for binary compatibility reasons, but will be fixed in Scala.js 1.x.
• #3433 UTF-8 CharsetDecoder doesn’t handle incomplete character ranges correctly
• #3417 Crash in jsDependencies resolution on Windows due to some path issue
• #3415 Optimizer stack-overflows, inlining a method within a closure inside that method
• #3408 Sporadic test failures in org.scalajs.testcommon.RPCCore (NullPointerException)
• #3401 Groups are broken for regexes with in-line flags since 0.6.21
