This thread is for updates and discussions about the eventual Scala 2.13.16 release.
As of yet, we don’t know much about the release’s likely contents or timing. If no followup to 2.13.15 needs to be rushed out, then a typical timeframe might be 3–6 months.
Let’s use this thread to ask, propose, discuss.
We’ll need to build Scala 2.13.16 to support Scala 3.6 in the TASTy reader, but I think it can wait until after Scala 3.6.2 is out.
Reasoning:
So I think it’s fine for us to wait, especially since it hasn’t been very long since 2.13.15.
We are actively winding down the scala/scala PR queue for 2.13.16. If there’s anything you’re hoping will get in, the window of opportunity is starting to close.
(How long you have depends on the nature of the change, how long it might take to review, etc.)
We’re now in the final stages of dealing with the last few remaining PRs: Pull requests · scala/scala · GitHub
Other issues and PRs have been moved to the 2.13.17 milestone. I expect to have a release notes draft next week.
PRs merged, milestones closed… now waiting for community build results.
In the meantime, please review these draft release notes: Scala 2.13.16 release notes (DRAFT) by SethTisue · Pull Request #892 · scala/scala-dev · GitHub
Community build green — we have a release candidate! It is 2.13.16-bin-1f34012
(to use, see How do I use a nightly build of Scala? - Stack Overflow)
Please test!
We would be especially grateful if Windows users would make sure the REPL isn’t broken in your environment because of the JLine changes.
Because of the holidays, we’ll extend the usual testing periods. We will publish the final release to Maven Central no sooner than Fri Jan 3, and then fully announce no sooner than Wed Jan 8.
Seems the Scala team needs to buy a Windows PC 
Compiled the Scala Plugin for IntelliJ IDEA using the 2.13.16-bin-1f34012 RC. All tests passed. Thank you for preparing the release. 
When trying to build Scala Native I get java.lang.NoClassDefFoundError: xsbti/AnalysisCallback3 is it a known issue?
I’m using sbt 1.10.2, full stacktrace below

a bit more detail on this. even just verifying that it doesn’t blow up has value, but I would also hope that:
not a complete list of course, but those are usual points of failure
Probably sbt 1.10.6 works.
I guess the new Scala 2.13.16 compiler bridge is compiled against the latest Zinc.
Thanks, it helps. Probably it should be mentioned in release notes.
Can confirm Scala Native works fine with new RC
Perhaps we can ameliorate this somehow so that people aren’t forced onto newer sbt. We’ll look into it before release.
Let’s discuss the gory details on Fix `MatchError` when using `-sourcepath` by Friendseeker · Pull Request #10905 · scala/scala · GitHub rather than here.
I had to disable -Xfatal-warnings because of the AnyRefMap deprecation, but otherwise Scala.js 1.17.0 worked fine with the RC.
As you can see from my screenshot above, I have no colors.
However, I recall also checking the stable Scala 2.13 and having no colors on windows so… I don’t know… (I do see colors on my Linux machine)
Maybe someone else can confirm if this is expected.
Glad to hear it’s otherwise working; thanks for the report.
But as long as there’s no regression since 2.13.15 that’s good enough for me
But regardless, perhaps someone has some ideas for you about how to get the colors to show up. Mind moving that to a separate thread on the users forum? (Feel free to link to that thread from here.)
