What's the status of kotlinx-io?

I’ve been playing with coroutines and was looking if there was a way to asynchronously block when reading an InputStream. I came across GitHub - Kotlin/kotlinx-io: Kotlin multiplatform I/O library which looks like it has some really useful stuff but it seems like it hasn’t been updated in a while, is it still being worked on?

Oops, guess I totally missed that. Thanks, I’ll follow that branch.

Wish there was a bit of a roadmap or just some more information about this project. I’ve been watching keenly for a while now with no response when I ask for more info.
