In January 2025, two targeted documentation updates were delivered across scala/scala and dotty-staging/dotty to align with Scala 3 and remove outdated 2.10 references. These changes improve onboarding, reduce ambiguity for users migrating to Scala 3, and establish a clearer documentation baseline for future releases.
