This thread is for updates and discussions about the eventual Scala 2.13.13 release.
As of yet, we don’t know much about the release’s likely timing or contents.
We can use this thread to ask, propose, discuss.

With Java 21 will be released this month , hope the next Scala release will have the best support for JDK 21:)
Is it too late in the season to release on next Friday the 13th?

We aren’t currently aware of any compatibility issues with JDK 21 that need to be addressed, but we encourage people to open tickets about any issues they find.
One area where we tend to lag is compatibility with the new Java language features, for users who are doing mixed Java/Scala compilation. For example, support for Java record syntax in Scala’s Java language parser only just landed in 3.3.1. Please open tickets or upvote existing tickets.
(Also, note that Java language handling improvements are a fertile area for open-source contributors — it’s valuable work that doesn’t require deep knowledge of compiler internals.)

Maybe worth to know: Debian Testing has OpenJDK 22-ea builds available since some time already.
Maybe this could be incorporated into some automatic tests?
Yes, good suggestion. For Scala 2, I have opened these two tickets to track it:
- https://github.com/scala/scala-dev/issues/852
- Add JDK 22-ea to build matrix · Issue #1698 · scala/community-build · GitHub
and assigned myself to both tickets.
For Scala 3, I ask that someone else open tickets and/or take responsibility.
