Hi, here is the latest KSP bi-weekly release: Highlights • Multiplatform is back working again for JVM platform. • Corresponding Kotlin version is bumped to 1.4.31. This release still works with 1.4.30. To mute the version mismatch warning when using with Kotlin-1.4.30, use 

-Pksp.version.check=false

. • Supported Gradle 7.0-rc-1. API / behavior changes • Use-site annotations are now attached to use-sites consistently. Previously, they are attached to where they were declared if the source is available, and the use-sites if the source isn't available. As always, please give it a try and let us know what you think, especially on the API design!

Is it multiplatform yet? If no, any ETA for at least kotlin js support?

Kotlin JS depends on this upstream patch. There is no ETA but we'll support it as early as possible once the patch is available in stable Kotlin compiler release.

Since that pr got merged, do you guys have any ETA for mpp support?

We should be able to support it once Kotlin 1.5.20 is released. JS will be supported first. Native may take a couple of weeks longer.

Js is exactly what I'm after. Thanks for clarifying, can't wait for 1.5.20 now!

Why JS first? I had thought JS might come later since the PR only supported the legacy backend. (Not complaining. Just want to understand what to expect timeline-wise)

It's more complicated for K/N in kotlin-gradle-plugin; K/JS shares most of the logic with K/JVM, while we need to have a lot re-implemented (not much effort but still...) for K/N in KSP's gradle plugin.
