🛠️ sbt 2.0.0 is released! sbt 2.0 is a new major series of sbt, based on Scala 3 constructs and Bazel-compatible cache system. many thanks to Scala Center, Anatolii Kmetiuk (new maintainer), Adrien Piquerez (alumni), and other volunteers like Kenji Yoshida eed3si9n.com/sbt-2.0.0 #Scala

The Scala Center is working on improving Scala's documentation and website. This blog post describes what we hope to achieve in 2026, based on community feedback: www.scala-lang.org/blog/2026/0...

I have forked and published sbt-revolver with experimental Scala Native support – running long-lived Scala Native processes in the background directly from your sbt build. Things like HTTP servers and UI (e.g. gtk) apps seem to work. Also ported sbt 2 support from upstream.

Recording of my talk from Scalar is up. In the talk, I invite you to a gentle waltz with a 50-year-old sabre-tooth behemoth called C and why Scala should care about learning to communicate with it.

Felt cute, thought I'd do some compile time numbers

Thought I'd see how sharp the bleeding edge is and converted my Scala Native CLI tool build from scala-cli to sbt2. And it works! Machine-wide caching works too, great for Github Actions

Time to meet again 🥰 🙌 Scala Days 2026 🗓️ Conference 12 - 13 October 🛠️ Workshops 14 - 15 October 📍Berlin, Germany Looking forward to welcoming you this autumn! scala-lang.org/blog/...

Finally got around to do a tool I desperately need – Scala Native-specific interactive binary size explorer. $ sn-sizer serve test-binary Starting server on localhost:52616

Thank you for attending last week's Scala Talks! Thanks go to Mercator for having us round for pizza, drinks and a beautiful venue. Special thanks go to our fantastic speakers @jatcwang.bsky.social and Jack Higgs. See you next time!

👩‍🔬 sbt 2.0.0-RC9 is released! sbt 2.0 is a new version of sbt, based on Scala 3 constructs and Bazel-compatible cache system RC9 is a big change, featuring - JDK 17 + Scala 3.8.1 in metabuild - Maven BOM (Bill of Materials) usage support eed3si9n.com/sbt-2.0.0-RC9 #Scala (1/n)

happy to announce that along with Scala library, compiler, sbt 2.0 project has been awarded Sovereign Tech Fund (German gov grant), recognized as a critical digital infrastructure, or an xkcd open source picture scala-lang.org/blog/2026/01... #Scala

By the way I am taking lead on the Scala standard library project and am open here for suggestions on what we should be working on - the sky is the limit! Or find the contributors forum post.

✨ Sometimes a bit of frustration leads to good questions. This talk looks at what Scala highlighting gets right, what it gets wrong, and why it still matters. Here’s "Tree Sitting will continue until Scala highlighting improves" by Anton Sviridov

Anton Sviridov: Tree Sitting will continue until Scala highlighting improves [Scala Days 2025]

In this talk we take a problem – accurate Scala syntax highlighting – and build a microcosm of tools around it, relying on industry-proven Tree Sitter grammars and parsers. Good tooling follows you across platforms, locations, and usecases, and so we will build a browser app with Scala.js, a CLI wit

Here's a live coding session I did for London Scala User Group about Scala Native and how it can interop with C, C++, and even Assembly. Super fun, by the end of it we had a blazing fast HTTP server built with a sprinkle of ARM64 assembly www.youtube.com/watch?v=rRPe...
