We are happy to announce three new Scala releases: 2.11.11 concludes the 2.11 series, 2.12.2 brings bug fixes and small improvements, and 2.13.0-M1 sets the scene for modularization and improvements coming in the next major release next year. Many thanks to everyone who contributed!
Scala 2.11.11 contains many smaller fixes and a few backports from 2.12. It also features improved error messages on missing dependencies; this improvement was developed by @jvican at the Scala Center under proposal SCP-009, which aims to speed up builds by shrinking the build classpath.
(Yes, we skipped 2.11.9 and 2.11.10. Special thanks to @xuwei-k and @sjrd for reporting and helping diagnose the regressions in those withdrawn releases.)
Scala 2.13.0-M1 prepares for the next phase of the standard library modularization and the collections rework. The parallel collections are now a separate module, and many deprecated members have been removed. As a reminder, our full 2.13 roadmap is available for review on GitHub.
