📣 📣 📣 kotlinx.coroutines 1.6.0-RC is here!
Major highligths:

• Completely reworked and now multiplatform kotlinx-coroutines-test module.
• New API to manage dispatchers: limitedParallelism along with <http://Dispatchers.IO|Dispatchers.IO> being unbound for limited parallelism views.
• K/N new memory model is now part of the release and all the coroutine primitives can be shared across multiple threads if the new memory model is enabled.
• A lot of improvements and bug fixes.
Full changelog: https://github.com/Kotlin/kotlinx.coroutines/releases/tag/1.6.0-RC

[Joffrey]

Awesome, I was looking forward to seeing the kotlinx-coroutines-test lib become multiplatform. THANK YOU 🙏

[Big Chungus]

+1 to that. I can finally remove my hacky workarounds in jsMain(s) 😄

macOS, iOS and so on are missing

[Javier]

@Vsevolod Tolstopyatov [JB] are they being deployed or there was an issue?

[Vsevolod Tolstopyatov [JB]]

@Javier it seems to be in order: https://repo1.maven.org/maven2/org/jetbrains/kotlinx/kotlinx-coroutines-core-macosx64/1.6.0-RC/
https://repo1.maven.org/maven2/org/jetbrains/kotlinx/kotlinx-coroutines-core-macosarm64/1.6.0-RC/
https://repo1.maven.org/maven2/org/jetbrains/kotlinx/kotlinx-coroutines-core-iosarm64/1.6.0-RC/
https://repo1.maven.org/maven2/org/jetbrains/kotlinx/kotlinx-coroutines-core-iosarm32/1.6.0-RC/

[Joffrey]

@Vsevolod Tolstopyatov [JB] his point was about kotlinx-coroutines-test, not kotlinx-coroutines-core

[Joffrey]

And indeed I don't see iOS stuff either:

[Vsevolod Tolstopyatov [JB]]

Oh, thanks for pointing it out! It seems to be either build or sonatype issue, I’m investigating it right now

[Trevor Stone]

Will there be a native-mt for 1.6.0-RC?

[Big Chungus]

No, release notes state that -native-mt is no longer needed and main artefacts will pick up new memory model if enabled.

[Trevor Stone]

But the new memory model isn't production ready yet

[Trevor Stone]

From the release notes if you are opted in it will use, which is great, but if you aren't opted in I assumed it defaults to the old single threaded implementation

[Big Chungus]

Oh you mean frozen mt. Yeah, might be worth sticking with -native-mt until new mm stabilises. No idea then.

[Javier]

@Vsevolod Tolstopyatov [JB] still missing apple artifacts 😞

[Javier]

@Vsevolod Tolstopyatov [JB]] I know I am disturbing, but is there any ETA about this one? maybe 1.6.0 final?

[Vsevolod Tolstopyatov [JB]]

I’ve located the problem and the proper artifcats will either be released along with 1.6.0 final or 1.6.0-RC2

[louiscad]

What was the problem exactly?

[Javier]

milestones are on github?

[Joffrey]

Do you have any ETA for the 1.6.0-RC2 or 1.6.0 release with iOS artifacts?
