Release Notes

pnpm/pnpm (pnpm)

v12.9.1: pnpm 12.9.1

Compare Source

This release moves the WebContainer build into a separate @pnpm/wasm package, shrinks the pnpm package back to about 4 MB, and fixes pnpm publish with provenance from GitLab CI.

Patch Changes

• The WebAssembly build for StackBlitz WebContainers now ships as a separate @pnpm/wasm package. The pnpm and @pnpm/exe packages no longer include it, which brings their unpacked size back from about 55 MB to about 4 MB. In a WebContainer, install @pnpm/wasm with npm to get the pnpm command.

• pnpm publish with provenance from GitLab CI is no longer rejected by the npm registry with a 422 error. The provenance statement now includes the GitLab CI variables in invocation.parameters, as npm does #​16551.

• pnpm audit signatures now uses the TLS settings of the redirect target when a registry redirects its signing-keys request, for example to registry.npmjs.org. A cafile scoped to a private registry no longer makes the redirected request fail #​16541.

• Fixed pnpm install --frozen-lockfile rejecting an up-to-date lockfile when an injected workspace package uses a catalog entry in peerDependencies #​16557.

• The [<since>] filter selector works again with Git 2.24 through 2.27 #​16561. With Git older than 2.24, the selector now fails with an error that names the required Git version.

  It also detects changes in projects whose directory names contain non-ASCII characters. Such a change used to be credited to the parent project. changedFilesIgnorePattern and testPattern now match changed files whose names contain non-ASCII characters.

• The pnpm executable is about 10% smaller. On macOS arm64 it went from 45.1 MB to 40.3 MB.

• Sped up trust downgrade checks for packages with long release histories.

• With optimisticRepeatInstall: false, pnpm install now runs the projects' own lifecycle scripts, such as prepare, even when node_modules is already up to date #​16545.

• pnpm self-update now fails for Homebrew-installed pnpm and prints the brew upgrade command for the installed formula, such as brew upgrade pnpm or brew upgrade pnpm@11. It used to install a second copy of pnpm that the Homebrew one kept shadowing #​16547.
