Scala 2.12.14 planning

Announcements
1

This thread is for updates and discussions about an eventual Scala 2.12.14 release.

2.12.13 was released on January 12. We aren’t aware of any regressions that would warrant rushing a followup. It isn’t clear yet what the main determinant of 2.12.14’s timing will be. We can talk about it here.

(as I also said on the 2.13.5 thread)

One motivation for 2.12.14 (and 2.13.5) will be to ship support for JDK 16. I’m currently working JDK 16 through the Scala 2 community build:

Which has so far turned up the need to upgrade to ASM 9:

And may yet turn up other issues.

In the meantime, people wanting to get an early start on JDK 16 testing can use our nightly builds.

Perhaps another reason:
https://github.com/apache/spark/pull/31223 was reverted due to https://github.com/scala/bug/issues/12038, which has been fixed post 2.12.13. For spark to upgrade scala (and publish 2.13 artefacts), having the fix sooner rather than later would probably be helpful.

Time to wind down the PR queue for 2.12.14! We’ve set a tentative target release date of April 9, but that could certainly slip.

If there’s anything anyone was hoping would make 2.12.14, please pipe up on the issue or PR in question (or inquire here).

At present there is only one small, easily addressed blocker on the milestone, but perhaps we can get some additional PRs over the finish line in the next couple weeks.

Jason hopes to finish up 2.12.14 this week. (As always, it’s hard to be sure just how long the long tail of mop-up work is…)

I don’t think you’re going to make it.

Any news on this? It would be great if we can get this one available so other projects could catch up with it and be able to work on more recent versions of the JVM

The sbt plugins for Scala.js v1.5.1 and Scala Native v0.4.0 are on their way to Maven Central as well, if they’re not already there.
