State of the Scala 2 Union

About this Session

Get the latest on Scala 2.13, 2.14 and beyond!

After the massive rework of the collections in 2.13,we're turning our attention to language simplification in the 2.14 release,

and the language takes another step towards Scala 3.0.

For 2.14, we're working on removing some of the sharper edges of the language, such as:

  • package object (top-level definitions instead)
  • trait parameters instead of early initializers
  • simpler extension methods (implicit classes extending AnyVal are hard to get right)
  • opaque types
  • a more narrow implicit scope

Finally, on to 3.0!
