Typelevel in 2016
summary
Typelevel reports concrete progress: Cats reaches ~2,000 commits and ~100 contributors and splits a stable Cats kernel for binary-stable reuse; projects (Shapeless, Spire, Algebra, Circe, scodec, doobie, Monix, FS2) show real integrations and Scala.js support. A long‑standing compiler bug SI-2712 gets fixed via a small patch (20–30 lines) after a compiler‑plugin proof‑of‑concept, and the fix is merged, proving compiler contributions are practical and compile‑time derivation and implicit issues can be materially improved.
