> As an outsider, I thought v3.0 was released last year[0]. Can someone explain?

Scala 3 (commonly known as Dotty before Scala3 official release) has been available for a while so that users could try it, submit suggestions, etc. This was done mainly by library authors that started cross-compiling libraries to Scala 3.

> Also, would a 6% increase over 3 years for v3.x, vs a 56% increase for v2.13, indicate v3 is not favored?

Similarly, Scala3 is being adopted first by library authors, and, it is the suggested choice for new projects, the migration to Scala 3 is very simple if the libraries you depend on are published to Scala 3, still, existing projects are migrating slowly.

I have migrated some apps to Scala3, and, I rolled back one of those to Scala 2.13. Also, I work with multiple customers that use Scala, the main reason they haven't moved to Scala3 is because IntelliJ still requires more improvements while working on Scala3.
