is there a kotlin roadmap somewhere? I'd like to have at least a vague idea of where most effort is being spent right now and also what's coming (or might be coming) in the future

I sometimes browse YouTrack with filter for the next version and feature tag: https://youtrack.jetbrains.com/issues?q=Target%20versions:%201.3.60%20%23Feature%20

Android Backstage Ep 119 has interview with Andrew Breslav discusses some of the medium and longer term initiatives they are working on

Thanks, I'll check both out

hopefully we’ll hear more at kotlinconf
