- pnpm 11 requires Node 22+, runs as pure ESM and the standalone binary now needs glibc ≥ 2.27, dropping support for Node 18‑21 (breaking).
- Supply‑chain protection defaults are enabled (minimumReleaseAge = 1 day, blockExoticSubdeps = true) and the new allowBuilds setting replaces old build‑script controls (security/feature).
- Adds a SQLite‑backed store index, isolated global installs via a virtual store, native publish/login/etc., and many new commands (pnpm ci, sbom, clean, …) while removing npm‑CLI passthrough commands (feature/breaking).
