Release 3.0.0

Scala 3.0.0 FINAL is here! After years of development, the project that was once known as Dotty, is now available. The ecosystem is pushing full steam ahead as we speak, releasing all the libraries that we know and love from Scala 2, so that you could start experimenting and developing using all of the goodies that come with the new release.

We're taking this occasion to release a special issue, with some Scala-3-related links from previous ScalaTimes issues, introducing new features or detailing out migration paths. Keep in mind this is only the tip of the iceberg, you can find much more in ScalaTimes archives!

Congratulations to Martin Odersky, Nicolas Stucki, Guillaume Martres and the rest of the EPFL & ScalaCenter teams!
