Bundler 2
summary
Bundler 2 refactors compatibility and workflow: it drops unsupported Ruby versions (up through 2.3), removes built‑in Capistrano and old source shortcuts, and introduces concrete commands and APIs like bundle add, bundler doctor and a plugin API (command and hook plugins). Resolver and install speed improve, plus a global gem extension cache to avoid recompiling across Ruby versions and specific platforms support so the resolver picks platform‑matched gem variants. bundle show splits into bundle list and bundle info; behavior is not backwards compatible with Bundler 1.
