" summary

Exercism v3 (released 1 Sep 2021) replaces forced local setup with a web editor plus per-language test runners that run inside Docker (read-only FS, no network), adds a syllabus of 50+ Elixir concepts with 30+ learning exercises, and deploys automated feedback via an analyzer and a representer that normalizes code and reuses mentor comments. Mentoring becomes optional, uses 1–4 reputation-based slots, and queues show student history; platform backend is Ruby on Rails with a React frontend and an old CLI in Go.
