Congratulations to the team!!
Scala has been critiqued a lot online, from what I've seen atleast, and the Scala team took that feedback and are actively trying to solve it. From bettter tooling to simplifying language features, I want to thank everybody that has been part of the incremental improvements for Scala!
Libraries that don't rely on macros have been fast to get compatibility with Scala 3.0.0, so I'm glad to see it's not an entire Python 2 -> Python 3 situation all over again.
Hoping for many more years of Scala fun.
