⏳ The Scala Survey 2026 closes tomorrow, 26th March 2026, 23:59 CET! This is your last chance to shape the future of the ecosystem. Attending Scalar this Friday? Stop by our booth for an exclusive sneak peek at the early results! 🚀 Vote here: virtuslab.typeform.com/ScalaSurvey2026

Hey, the Scala 2 bytecode optimizer just got ported to Scala 3! While writing nice, high level code, let the optimizer then make it faster. Try it out today on Scala 3.8.3-RC3 with -opt. Read more at scala-lang.org/blog/2026/03/2…

Martin's whitepaper is available at Arxiv - "Tracking Capabilities for Safer Agents" by Odersky, Zhao, Xu, Bračevac and Pham. Links to papers below: arxiv.org/pdf/2603.00991 anthropic.com/engineering/ad…

Should your agent get prompt-injected and generate code that tries to, for example, send classified data to an external server, it would be a compile error as classified data simply can't flow into network calls. 7/8

Anthropic says JSON tool calls aren't the best thing since sliced bread and that if your agent glues tool calls together using code, it becomes 37% more token-efficient with less inference and better accuracy. Should you just let it write Python in a docker sandbox though? 1/8

It's your last chance to be an important part of the Scala community. Take a quick 5‑minute survey that directly impacts Scala’s roadmap, libraries, and tooling. We'll evaluate the outcome soon. Stop by the Scalar Conference on the 26th and 27th of March to be among the first to see the data! This short survey evaluates Scala adoption and usage among developers. Click the link virtuslab.typeform.com/ScalaSurvey2026 and complete the survey now to help shape the future of Scala. Scala Survey 2026 is brought to you by VirtusLab and Scala Center.

This wasn’t an easy change to make, due to how Homebrew requires packages to be built. If you’re interested in the specifics, take a look at the PR itself: github.com/Homebrew/homeb…

If you're using macOS and Homebrew, we have some great news for you! Thanks to the great work by Piotr Chabelski, installing Scala via Homebrew now includes native-image binaries. This means the CLI starts faster and doesn’t require Java to be installed on your machine.

If you're in London today, join us on the London Scala meetup. We'll be talking about how Metals can help you will large Scala and Java codebases. There will also be a great presentation on real life crashes in production. See you there! meetup.com/london-scala/e…

New Metals 1.6.6 is out! - Allow users to view the output of `-explain` - Standalone MCP server - Option to automatically shut down Bloop - Support for Play Twirl templates - Improvements to new file creation Learn more at scalameta.org/metals/blog/20…

If you're interested in Scala 2 and Scala 3 compatibility, what TASTy is, and how it fits into the whole story, take a look at this blog post by Wojciech Mazur. scala-lang.org/blog/state-of-…

sttp-ai now supports #Scala Native! You can use: OpenAI, Claude, Grok, Ollama, ... With different flavours of Scala: direct, functional, Future-based On various platforms: JVM & Native (not all combinations are supported, though) Enjoy :)

If you don’t specify a port, a random one will be used—unless the server has already run in the workspace. In that case, it will try to reuse the same port (if available). We still don’t support the stdio option, but if anyone is interested in having it implemented, let us know!

Next, you can run the generated executable JAR from within your workspace, or specify the full path using the `--workspace` argument. You can also use the `--client` option. For all known MCP clients, it will try to automatically create the required configuration entries.

In the upcoming Metals version, you’ll be able to start it standalone as an MCP server! You can already try it out in two steps: First, bootstrap your executable JAR using Coursier.
