Our Commentary ​

The dedupePeers feature in pnpm 10.33 is a really smart optimization. Anyone who's wrestled with node_modules bloat or deeply nested peer dependency structures knows the pain. Reducing package instances can have a tangible impact on disk space, install times, and even build performance. It's these kinds of incremental improvements in tooling that make a real difference in developer experience over time. pnpm continues to innovate in package management, and this release is another step in making dependency graphs more manageable.
