• Many small fixes and improvements!
Details <https://github.com/Kotlin/kotlinx.coroutines/releases/tag/1.9.0-RC.2>

Seems it's not on maven or sonatype yet <https://central.sonatype.com/artifact/org.jetbrains.kotlinx/kotlinx-coroutines-core-js/1.9.0-RC.2> returns 404

It sometimes takes half an hour for the system to recognize that there's a new version. The link is no longer 404.

Thanks yes it works now, since it was published yesterday on Github I thought it could have been a push issue as the build there is still waiting.

I'm curious, why are breaking changes being made in a minor release? Does the coroutines lib not follow semver?

Nope. Coroutines are versioned as `1.X.Y`, and breaking changes are allowed to occur in `X`.
