Last week, we announced the release of Scala 3.4.0 and 3.3.3. The announcement mentioned that we had to skip 3.3.2 due to a bug breaking our forward binary compatibility guarantees in a patch release. In this post, we take a closer look at what happened, why it slipped through our existing testing processes, and what steps we are taking so that it does not happen again in the future. Symptoms of the bug First, let us look at the scenario in which the bug surfaces: Compile a library A with Scala 3.3.2 Compile a project B, depending on A, with Scala 3.3.1 (or 3.3.0) The older compiler crashes w ..read more

We are thrilled to announce the release of two versions of Scala 3: the first version in the 3.4 minor line, and a patch version in the Long Term Support line. … so which version should I update to? Scala 3.4.0 code can use dependencies compiled with Scala 3.3.x, but not the other way around. That means that if you are a library author, you should stay on the LTS line. Moreover, you can safely bump the patch version of the LTS release and benefit from the bugfixes without forcing any updates on the consumers of your library, even in regard to the patch version. If you are working on a project ..read more

My name is Jay, I am a software engineer and developer advocate. We’ve recently migrated a major project from Scala 2 to Scala 3 at $WORK. In this article, I’d like to share the lessons we learned as well as some tips. Implicit context Before doing any actual personal work, based on Internet discussions, I had the impression that switching to Scala 3 would be quite painful. In practice, it was pretty straightforward. In retrospect, our experience was determined by the technology stack and tools that I (and my team) use: a microservice architecture, the Typelevel stack, VS Code with Metals, and ..read more
