Closing panel
summary
Panel lists concrete tooling and migration plans: a time-based six-week release cadence for Dotty previews, commitment to keep the standard library identical between 2.14 and 3.0, and using TASTy binary artifacts to solve accidental JVM binary breakage. Work is underway on SemanticDB/scalafix recipes, a Language Server Protocol working group, Apache Arrow bindings and multi-language notebooks, and efforts to help Spark reach Scala 2.12. The roadmap aims to avoid runtime breaks (about 90% of changes) and relies on funded contributions via the Scala Center.
