May I ask you to include a PR to update scastie, in the release procedure? see scalacenter/scastie#660

[Kordyjan]

@julienrf this was what I meant by "Wait for confirmation from [...] Scastie". As we agreed with @rochala to just notify him when the new version should start being available.
Of course I can make creating the PR as a part of the release scripts.

[julienrf]

Oh sorry I missed that “scastie” item in the list, nevermind! Thank you!

Here is the release of scala-expresion-compiler_3.2.2 needed by the scala-debug-adapter

[tgodzik]

3.2.2 support is added for the latest metals and merged in main 🎉

Let us know when the next RC is on maven

[WojciechMazur]

Scala Native compiler plugins for 3.2.2 are released for versions 0.4.6 .. 0.4.9 (latest)

[lwronski]

I confirm that the scala-cli works with Scala 3.2.2 and it will be the default version in the upcoming release - 0.1.20.

[Kordyjan]

The whole release procedure has been on hold for a few days because we need to get #16612 right to release 3.3.0-RC1.

[Kordyjan]

Unfortunately, we have a problem with 3.3.0-RC1. It generates output with the wrong TASTy version. There will be RC2 later today.

Regarding Wikipedia and 3.2.2 etc.: the data in wikidata at https://www.wikidata.org/wiki/Q460584 (scroll down to the respective section) which backs the Wikipedia page https://en.wikipedia.org/wiki/Scala_(programming_language) is somewhat outdated and should be updated.

(I tried to update this myself, but seems I have no permission editing without a user account over there. Also, I have no information whether or not someone at the Scala Center keeps that information up to date.)

[SethTisue]

I'll assume it's inadvertent this ticket wasn't already closed.

3.2.2, 3.3.0-RC2, and 3.3.0-RC3 are already out, and my understanding is that 3.3.0-RC4 is imminent (next week, perhaps?).

(Re: Wikidata, updating it certainly isn't part of the Scala 2 release steps. I'd be surprised if it were in the Scala 3 release steps, but I've been surprised before.)
