pnpm 12.5 expands Python support with editable project packages, shared workspace environments, automatic interpreter downloads, and lockfiles for multiple platforms and Python versions. It also accepts Package URLs in pnpm add, adds machine-wide task concurrency groups, and cleans up obsolete registry metadata with pnpm cache prune.

pnpm 12.4 installs crates and Python packages next to npm packages in the same workspace, adds pnpm pipeline to run a workspace's tasks the way a CI job would, and ships binaries for six more platforms. pnpr 0.1.0-alpha.11, released alongside 12.4.1, serves Cargo, Python, and container registries beside npm, publishes across all of them in one transaction, and signs users in through OIDC.

pnpm 11.26 brings the JavaScript CLI level with what pnpm 12 gained over the past two weeks: workspace: ranges in catalogs, the supply-chain flags on remove and update, pnpm change check for CI, and pnpm deploy without injected dependencies.

pnpm 12.2 and 12.3 are largely a catch-up pair: a long list of things pnpm 11 did that the Rust CLI did not, put back. Catalogs learned the workspace: protocol, pnpm remove and pnpm update gained the supply-chain flags, every project-aware global command became a real executable, and hostname resolution went back to the system resolver on Linux and Windows. Large workspaces install noticeably faster.

pnpm 11.25 replaces topological batches with a task scheduler, adds configurable workspace task dependencies and per-task concurrency, and makes interrupted recursive runs resumable from the work that actually passed. It also introduces registry revisions, signed build artifacts shared through pnpr, batch approval for staged packages, automatic pruning of stale audit exceptions, and a pnpm init pin that follows the latest released pnpm.

pnpm 12.1 brings the new workspace task scheduler to the Rust CLI, persists successful recursive tasks for precise retries, expands shared build artifacts to macOS and Windows, and moves login credentials into pnpm's structured global configuration. pnpr 0.1.0-alpha.9, released with it, makes the artifact tier independent and horizontally scalable through S3-compatible storage.

pnpm 12 is stable. It is a rewrite of pnpm in Rust. Upgrading should not feel like a migration. The commands, flags, settings, and lockfile format of pnpm 11 all carry over. The documentation now defaults to pnpm 12, with the pnpm 11 documentation available from the version selector.

The few things that behave differently are listed in What's different in pnpm 12. This post covers what is new.

pnpm 11.24 brings back pnpm approve-builds --global, which isolated global installs took away in v11.0, and makes recursive batch publishing group its packages by registry so a credential mismatch is caught before anything is published. It also stops --frozen-lockfile from failing over the pnpm version the lockfile pins.

pnpm 11.23 gives the registries setting a shape that describes each registry once — its tarball layout, the scopes routed to it, the prefix it answers to — so an Artifactory or GitLab registry can finally keep its tarball URLs out of pnpm-lock.yaml. It adds virtualStoreType, makes undeclared imports resolve under ESM with the global virtual store without a plugin, teaches pnpm config get to report the settings pnpm actually acts on, and warns about settings no pnpm version recognizes.

pnpm 11.21 and 11.22 teach pnpm install to update the lockfile in place for most everyday changes instead of re-resolving the whole dependency graph, stop recording SSH URLs that break installs on CI, make global installs switch over atomically and global interactive updates select whole install groups, add pnpm cache path, and take away a project's ability to relocate pnpm's machine-level state through pnpm-workspace.yaml.
