v2.11.12: Scala 2.11.12

Compare Source

Scala 2.11.12 is a maintenance release to allow running Scala 2.11 tooling on Java 9. Five pending backports were merged.

This release addresses (#​6108) a privilege escalation vulnerability that was identified in the Scala compilation daemon CVE-2017-15288.

We strongly encourage you to upgrade to the latest stable version of Scala 2.12.x, as the 2.11.x series is no longer actively maintained.

There is a known bug on Java 9 involving the repl: the workaround is to launch it as scala -nobootcp.

More general information about the Scala 2.11 series is available in the release notes for Scala 2.11.1.

Thanks to Lightbend for their continued sponsorship of the Scala core team’s efforts. Lightbend offers commercial support for Scala.
