June 2026: Stability improvements for workspace deduplication in pnpm. Fixed a bug where running pnpm rm inside a workspace package with dependencies could switch the lockfile protocol from link: to file:. In single-project mode, deduplication could be incorrectly applied to workspace dependencies with children, risking lockfile integrity. Implemented a defensive guard and updated resolution logic so dedupe is safe and preserves link: for valid cases; improved depPath resolution for peer-suffixed dependencies. This change reduces lockfile churn and prevents hidden breakages in monorepos. Co-authored by Claude Opus and Zoltan Kochan.

March 2026 focused on stabilizing workspace handling and dependency resolution in pnpm/pnpm, delivering a robust fix for workspace package identification across operations and tightening dependency resolution for consistent multi-project behavior. Implemented performance-oriented refactors and expanded tests to reflect real-world usage, including single-package removal paths. Result: higher reliability, fewer install/uninstall edge cases, and a cleaner codebase for monorepos.
