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.
