Exercism v3
summary
Exercism v3 (released 2021-09-01) adds an in-browser web editor and per-language test runners (run in Docker with read‑only filesystems and no network) so exercises can be solved without local setup, a track syllabus with 50+ concepts for Elixir plus 30+ learning exercises and matched practice problems, and automated feedback via analyzers and representers that normalize code, detect patterns, and attach reusable mentor comments; mentoring becomes optional, queued with 1–4 slots and reputation-based prioritization.
