In this talk, I will introduce the highlights of what to look forward to in Scala 3.9 LTS, as well as how to think about the upcoming new release.
The new Scala 3.9 LTS is planned to arrive in Q2 2026. With it, a wave of significant changes will soon flood the Scala ecosystem. Numerous language features, a new runner, a revamped REPL, bumped JDK, the list runs long.
In this talk, I will introduce the highlights of what to look forward to in Scala 3.9 LTS, as well as how to think about the upcoming new release. I will summarise the changes since 3.3 LTS, unpacking some of the development history. I will also talk about 3.3 LTS ongoing support, JDK compatibility and other things you might wonder about, thinking about Scala going forward.
In this talk, we will walk through a concrete example of a boilerplate-heavy domain. By replacing common Scala 2 workarounds with Opaque Types, Extension Methods, Enums, and Union Types, we will demonstrate how to achieve a strictly typed, decoupled architecture without the noise.
For nearly a decade, Scala's concurrency has been driven by Akka, Cats Effect and ZIO, each with its own vision for purity, safety, and pragmatism. Kyo enters this incredible ecosystem with a fresh perspective.This talk provides a critical, technical comparison of these systems through a unified framework.
This talk presents McCCT, a new concurrency testing tool developed at KTH by the speakers in the context of an ongoing research project.

We'll explore type classes in Scala 3, using its new rules for givens, extension methods, and mechanisms for automatic derivation via mirrors or macros.
