📣📣📣 kotlinx-coroutines 1.10.0 is here, using Kotlin 2.1!
It introduces a number of small technical changes, fixing many long-standing annoyances. Check out the full list at https://github.com/Kotlin/kotlinx.coroutines/releases/tag/1.10.0 to see if you, too, can remove some workaround from your code or build scripts!

When updated from 1.9.0 to 1.10.0 for Js and WasmJs targets got at runtime:

IrLinkageError: Function 'Runnable' can not be called: No function found for symbol 'kotlinx.coroutines/Runnable|Runnable(kotlin.Function0<kotlin.Unit>){}[0]

Kotlin: 2.1.20-Beta1

[Dmitry Khalanskiy [JB]]

Does this also happen with a clean build? If so, please file an issue.

Ok, could you please provide some way to reproduce the issue on our side? You could send your project (in private to JetBrains if you want), or preferably, a minimal project where the problem still occurs.

[PHondogo]

Will try to make it but it will take time to shrink it and remove all private code.

I also encountered this problem on iOS target, I can reproduce it using Wizard，here is the issue link:https://github.com/Kotlin/kotlinx.coroutines/issues/4309

Seems like Runnable symbol is JVM only and somehow it was referenced in non JVM targets. Just thoughts.

I also see a strange behaviour with 1.10.0. See: https://kotlinlang.slack.com/archives/C01F2HV7868/p1734686938985659

[Dmitry Khalanskiy [JB]]

We will publish a hotfix restoring the binary compatibility with Runnable today. Hopefully, this will solve all the reported issues!

📣 kotlinx-coroutines 1.10.1, a hotfix release restoring Compose binary compatibility for non JVM-targets, was published!
