The headline feature for this year's Scala release is a reworked collections library, with a focus on simplicity and performance. As we look forward to Scala 3, Adriaan is really excited to deliver the first significant part of his team's vision for the next decade of functional programming in Scala.

The collections library, being at the core of the Scala experience really exemplifies the functional programming philosophy behind the design of Scala. Adriaan will talk a bit about the design, implementation and migration story of the new library, which was lead by Stefan Zeiger from the Lightbend side, Julien Richard-Foy at the Scala Center and many outstanding contributors from the community. He'll also explore a few key changes to the type checker that enabled the simplifications in the design. Of course, Scala 2.13 comes with more goodies, such as better Java 11 support, an improved inliner, literal types, partial unification enabled by default.

For the "beyond" part of the talk, Adriaan will share his team's plans for 2.14, which will take a big step towards 3.0 for the compiler and core language, with support for TASTY, trait parameters, opaque types, and top-level definitions (assuming SIP approval). We care deeply about a smooth migration path as he evolves the language, and will go into some detail on his team's plans for that, as well as the highlights of the once-a-decade upcoming major release of Scala: 3.0!
