READING

Proceedings of the 12th ACM SIGPLAN International Symposium on Scala

A set of great papers collected for the Symposium.
On the future of Play Framework

We are working to form a community-led organization that would take responsibility for the future development of Play Framework outside of Lightbend.

Scala 3 and Spark?

Scala 3 projects can depend on Scala 2.13 libraries, so can we finally write Spark jobs using Scala 3? The answer is yes, in theory

RELEASES

Scala 3.1.0

Backward binary compatible, new experimental feature: safer exceptions, efficient bytecode for matching over strings, configurable compilation warnings, mirrors for Hierarchical Sealed Types, and a lot of other changes!
Scala contributors
Grackle

A GraphQL server implementation for Scala, powered by cats, cats-effect, and circe.
Grackle contributors
scalajs-dom 2.0.0

scala-js-dom v2.0.0 is the first release in the 2.x series. It is published for Scala 2.11, 2.12, 2.13, and 3.0+ with Scala.js 1.5+. Note that it breaks binary-compatibility with the 1.x series.
scala-js-dom contributors
Scala CLI

Scala CLI is an experimental tool to run/compile/test Scala that aims at being a better scala command. It shares some similarities with build tools, but doesn't aim at supporting multi-module projects, nor to be extended via a task system.
