🚀 Scala Days 2026 CfP is now open! https://lnkd.in/d-m9GPNb If you’ve been building with Scala, experimenting, shipping, learning - this is your opportunity to share it with the community! We’re looking for talks, interactive labs, and workshops that reflect how Scala is used in practice today - from real-world systems and tooling to data and AI work. 🛠 We’re especially interested in: • practical insights and experience reports • lessons learned from real systems • forward-looking ideas grounded in real use 📅 Submission deadline: May 31, 2026 🎟 Also, today, April 30th, is your last chance to grab the Early Bird ticket! Details and submission: https://lnkd.in/d-m9GPNb

The sbt 2 project has started the last mile process to lock down the 2.0.x branch. Depending on the bugs we discover, we are hopeful that a release candidate (currently 2.0.0-RC12) can graduate in a few weeks to a few months. https://lnkd.in/gSPYShyf

We’ve discovered and fixed a long-standing security vulnerability in sbt. The advisory addresses a remote code execution vulnerability (CVE-2026-32948) affecting sbt on Windows. The issue allows an attacker to mask a malicious command under a VCS dependency (e.g. a dependency on a git repository). This work is part of a broader effort to strengthen sbt as critical open-source infrastructure. Build tools like sbt sit deep in the software supply chain, which makes this kind of hardening work necessary to make the entire ecosystem more secure. If you are using sbt, especially on Windows, make sure to review the advisory: https://lnkd.in/ePyXJmvc

Hi all, The Scala Roadmap is now officially published at https://roadmap.sh/scala. It is a learning roadmap designed to help beginners decide what to learn and in what order, and to discover relevant resources. It is one of the largest roadmaps on roadmap.sh, featuring over 150 nodes, each accompanied by descriptions and links to articles, videos, and code examples. This project took several months of gathering information, brainstorming sessions, iterating over different designs, soliciting feedback, and more. While I believe a project of this size can never be perfect, I am confident in its quality. During my time as a Scala educator, I often received questions about where to start and what to do after learning the basics. I hope that people like me will now be able to point to this roadmap to answer such questions, as well as use it as a visual aid in their educational projects. Of course, Scala is evolving, and at some point we will need to update the Scala Roadmap. That is expected. However, many nodes cover concepts fundamental to both functional and object-oriented programming, as well as tools unlikely to become outdated in the near future. Maintenance should not be a significant burden. Finally, a word about the design: The purpose of a learning roadmap is to present resources in a linear or near-linear fashion, relieving students of the burden of making too many decisions. That said, this does not mean you must follow the path strictly. Rather, feel free to jump ahead, revisit earlier topics, explore related areas, and move in any direction you prefer. The path is meant to help you, not to restrict you. I hope it will be valuable to you. Cheers, Maciej #scala #learning #roadmap

Check out Scala 3's bytecode optimizer: https://lnkd.in/ehskwuC5 You can now write simple high-level code even in scenarios where performance is critical, and rely on the optimizer to make it as fast as if you had spent the time and energy writing low-level code! And of course, you get the maintainability benefits of high-level Scala code.

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. 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: https://lnkd.in/d2azpxGw

🧪 Measuring how much of your Scala code is covered by tests is a standard approach to quality assurance across the industry. In Scala 3, code coverage tooling is built into the compiler, ready to use out-of-the box. We've recently made progress on making Scoverage, Scala's default code coverage tool, more robust, expanding the way we test it, discovering and fixing new issues.
