During January 2025, this developer focused on stability-driven maintenance for the guardian/scala-steward repository, upgrading core dependencies and build tools to align with the evolving Scala ecosystem. They applied their expertise in Scala, dependency management, and build tool configuration to update libraries such as bcprov-jdk15to18 and scala-library, while also enhancing code formatting consistency using scalafmt. By automating formatting and refining .git-blame-ignore-revs, they improved blame traceability and commit hygiene. Their work also included updating CI tooling with sbt-scoverage and merge rules, resulting in reduced maintenance overhead, improved build stability, and a codebase better prepared for future Scala updates.
