∃ugene -Yokota 🥙@eed3si9n.com · 3w ago🧑🚒 released sbt 1.12.14 and 2.0.3, featuring - backport of CVE-2026-26032 fix for Ivy (while sbt might not be affected) - update to Jawn 1.7.0 for CVE-2026-59990 and CVE-2026-61814 fixes eed3si9n.com/sbt-1.12.14-... #Scala
Local/remote caching. This is probably the most interesting feature of sbt 2.x. sbt 1.x had cached compilation, but 2.x can generalize it to all tasks, including tests See Scala Days 2025 talk for more details (around 19:14) www.youtube.com/watch?v=GM2y... www.scala-sbt.org/2.x/docs/en/...
Towards the end of 2025, sbt 2 project got grant approval from the Sovereign Tech Fund (funded by German gov). This also accelerated the plugin migration effort: 1. Anatolii from Scala Center created the sbt2-compat plugin 2. @tanishiking.bsky.social from VirtusLab contributed Scala.JS cross build
Scala 3.x in the metabuild. sbt 2.x adopts Scala 3.x for its own codebase and the metabuild (currently 3.8.4), updating from Scala 2.12, which has maintenance implications for both the toolchain and plugins. Speaking of which, sbt 2 already has 108 plugins: index.scala-lang.org/search?platf...
Client-server by default. When the `sbt` runner detects an sbt 2.x build, it will now launch the native sbtn client by default. If you want, this allows you to use your system shell, instead of sbt's own shell, without reloading the build. sbtn launches a fresh JVM for run (client-side run)
