The pnpm v12 CLI is implemented in Rust. pacquet is its in-repository package name; the published CLI and executable are named pnpm.

pnpm v12 is the target for new feature development. The TypeScript pnpm v11 CLI under ../pnpm11/ is maintained for bug fixes. Bugs present in both versions are fixed in both implementations. Bugs present in only one version are fixed in that version. New features are not backported to v11.

See CONTRIBUTING.md for development setup, debugging, testing, and benchmarking.
