pnpm 11.28.12

pnpm 11.28.12 fixes many peer dependency, pnpm deploy, frozen-lockfile, and nodeLinker: hoisted bugs. It also includes a security fix. A ${VAR} placeholder in a repository's registry URL now fails the command, so pnpm no longer sends those requests to another registry. The bundled node-gyp no longer ships the undici version that security scanners flag, and remote resolution needs pnpr 0.1.0-alpha.20 or newer.

Patch Changes#

Upgrading and security#

  • A ${VAR} placeholder in a registry URL in pnpm-workspace.yaml or the project .npmrc now fails the command. pnpm does not expand environment variables in these files. Before, pnpm ignored such a URL and resolved packages from another registry, such as npmjs.org. pnpm now warns when it ignores a placeholder in a proxy, pnprServer, or userAgent setting in pnpm-workspace.yaml #17762.

  • The node-gyp bundled with pnpm no longer ships undici 6, which security scanners flag for CVE-2026-84947. On Node.js 26, node-gyp downloads through a proxy or with a custom CA file no longer crash with "invalid onError method" #17941.

  • Remote resolution and shared build caches no longer work with pnpr 0.1.0-alpha.19 or older. pnpm now reads the capabilities a pnpr server advertises under pnpr.protocols. Installs fail when the server does not confirm the requested resolution and verification policies. Upgrade the pnpr server before upgrading pnpm.

Installs that failed#

  • pnpm install --frozen-lockfile now succeeds when a workspace project recorded in pnpm-lock.yaml has an empty directory, such as a git submodule that was not checked out #17712.

  • pnpm install --frozen-lockfile now accepts a lockfile when an injected workspace package declares a file: or link: dependency with backslashes, such as file:..\vendor, or with a slash after the protocol, such as file:/./vendor. Before, the install reported the lockfile as out of date right after pnpm install had written it #17720.

  • pnpm install --frozen-lockfile and verifyDepsBeforeRun now accept a workspace: dependency on a project whose version is not valid semver, such as workspace:1 on a project at version 1. Before, they reported the lockfile that pnpm install had just written as out of date.

  • pnpm fetch no longer fails with ENOENT when nodeLinker is hoisted and the project configures patchedDependencies or allowBuilds. pnpm fetch also preserves an existing hoisted node_modules directory #18037.

  • Git dependencies now accept npm's :: separator between fragment parameters, such as github:owner/repo#v1.0.0::path:packages/foo. Before, pnpm read the whole fragment as a branch name and failed to resolve it #17827.

  • pnpm no longer fails to remove a dependency whose package.json is malformed. It removes the dependency and keeps its bins pnpm/tasks#295.

  • Fixed pnpm deprecate, pnpm undeprecate, and pnpm unpublish failing with revision conflicts when a registry cache serves stale package metadata.

  • When a package injected through a path, such as file:../lib or ../lib, gives one of its dependencies a catalog: specifier, pnpm install now fails the way a fresh resolution does, and pnpm install --frozen-lockfile reports the lockfile as outdated. Before, both could accept the existing lockfile #17722.

Peer dependencies#

  • Repeated installs no longer change the peer dependency providers that the previous install chose. This covers adding a dependency, removing a shared package from one workspace project, and projects that use different ranges of one dependency pnpm/tasks#221.

    An unchanged install keeps a valid locked peer provider even when a direct dependency provides another compatible version. Explicit pnpm add and pnpm update requests take precedence over it. Required dependencies no longer remain marked optional when another workspace project removes a shared package.

  • Workspace projects that select different versions of a peer provider no longer share one copy of the package that depends on it. This affected peers reached through an aliased dependency or a peer dependency cycle.

  • New workspace projects now prefer peer versions already pinned in the lockfile. Dependencies that are also optional peers no longer cause an unrelated project to select an older peer version.

  • With dedupePeerDependents: false, a missing optional peer is no longer resolved from a version that only another workspace project depends on. The workspace root's dependencies still count if resolvePeersFromWorkspaceRoot is true. Before, a tool in one project's devDependencies, such as webpack-cli, could become an optional peer of another project's production dependencies #16666.

  • pnpm install no longer gives a project an optional peer dependency that it skipped because a required peer would conflict with the project's dependencies. Before, dedupePeerDependents merged the project's copy of the package that declares the peer with another project's copy that resolves it #17781.

  • pnpm install no longer fills in a missing optional peer dependency if a required peer it brings in conflicts with a version the project depends on. Before, such a peer was installed along with it and reported as unmet #17718.

  • With autoInstallPeersFromHighestMatch, conflicting non-semver peer dependencies now remain missing, and identical non-semver peer specifiers are preserved. Preferred registry versions no longer replace local paths or protocol-prefixed specifiers when pnpm installs missing peers pnpm/tasks#272.

  • Fixed installation and peer dependency reporting for packages named constructor or toString. Optional peers with these names are also recognized when declared only in peerDependenciesMeta.

Resolving and linking dependencies#

  • A root overrides entry that points a package at a workspace: path, such as workspace:./packages/foo, now also applies when a registry package depends on that package pnpm/tasks#270.

  • Version-selector overrides entries such as "ms@^2.0.0": "2.1.1" now apply to dependencies declared with the catalog: protocol when the catalog entry's range matches the selector #17922.

  • An optional dependency that declares no os, cpu, or libc field is no longer skipped because its name contains only an operating system word, such as get-windows on macOS. pnpm now infers its platform from the name only when the name also has a cpu or libc token, such as -win32-x64 #17774.

  • pnpm dedupe now keeps a locked runtime version, from devEngines.runtime or from a dependency's engines.runtime, when the declared range still admits it. pnpm dedupe --check no longer fails each time a newer Node.js release in the range comes out #17984.

  • Resolving against a registry that sends Cache-Control: no-cache, such as Azure Artifacts, is fast again when the lockfile already decides the version. pnpm reads the cached metadata for a pinned version, or for a range the lockfile version is proven to win, without a registry request #17758.

  • Dependencies declared as workspace: entries in catalogs now remain in the lockfile when excludeLinksFromLockfile is enabled. Frozen installs can restore these links after node_modules is removed pnpm/tasks#260.

  • pnpm install --filter in a sparse checkout now counts the dependencies of workspace projects that are missing from disk when it resolves peer dependencies and marks packages as optional. The lockfile it writes no longer differs from a full checkout in those entries #17791.

  • With nodeLinker: hoisted, pnpm install --filter in a sparse checkout now drops previously installed workspace projects that are missing from disk from the hoisted node_modules tree. It no longer recreates node_modules inside a missing project's directory. Packages that only the missing project used are also removed from the root node_modules.

  • With nodeLinker: hoisted and a custom modulesDir, pnpm now installs a workspace project's dependencies that cannot be hoisted to the root into the project's modulesDir. The next install that relinks the project removes the copies that earlier installs left in its node_modules. A later install restores the project's modulesDir when it was removed. Package directories that pnpm did not install are now also moved to .ignored in a custom modulesDir.

  • With dedupeDirectDeps, pnpm install now compares link: dependencies by the directory they point at. A project's link: dependency is removed when the workspace root links the same directory under a different path. It is kept when the root's link: dependency has the same text but points at another directory. This also applies with nodeLinker: hoisted.

    pnpm install reports each removed link: dependency once pnpm/tasks#293.

  • A repeat pnpm install with nodeLinker: pnp now applies dependency and configuration changes. Before, it printed "Already up to date" and left the lockfile unchanged.

  • Config dependencies use the declared registry serverType when recording and installing packages pnpm/tasks#236.

pnpm deploy#

  • pnpm deploy no longer fails when the deployed project depends on a workspace package that sets publishConfig.directory. pnpm installs that package from its publish directory and runs its build scripts #17771.

  • pnpm deploy now runs the build scripts of a workspace project that it installs as a file: dependency, without a machine-specific allowBuilds key. An allowBuilds entry that denies the project still applies #17740.

  • pnpm deploy --offline --trust-lockfile now reuses dependencies pinned in the source lockfile from a populated store when registry metadata is unavailable. This works with per-project lockfiles, --legacy, and npm aliases #17888.

  • pnpm deploy preserves an injected workspace package's resolved dependencies when they differ from the workspace project's own dependencies. This also applies to packages with publishConfig.directory pnpm/tasks#221.

  • pnpm deploy now binds optional peers declared only in peerDependenciesMeta for linked workspace packages. The deployed manifest and lockfile also retain these peers when filtering dependency groups.

Builds, bins, and scripts#

  • Concurrent installs into a global virtual store no longer wait on each other. A package that needs a build is built in a private directory and moved into the store once its build has finished, so another project never links a half-built package. An install with --ignore-scripts links the packages it does not build from their own store directories, and pnpm store prune removes the build directories of installs that were interrupted #15568.

  • Packages that an older pnpm version added to the store now run their install scripts. Before, pnpm could skip those scripts and hardlink the package's files to the store. This includes git dependencies that an older pnpm marked in a shared store as not requiring a build pnpm/tasks#189.

  • Fixed pnpm store status reporting approved builds of git dependencies as modified when the store contains legacy build metadata.

  • pnpm store prune now stops if a dependency link cannot be read. This keeps installed packages from being removed after an incomplete scan.

  • When pnpm install adds placeholder entries to allowBuilds in pnpm-workspace.yaml, it no longer copies allowBuilds entries from other config sources into the file.

  • Bin shims in the global virtual store no longer include the hoisted modules directory of the project that installed them #18035.

  • POSIX bin shims and the pnpm, pn, pnpx, and pnx launchers now run inside a Nix build on macOS with the sandbox enabled. Installing again replaces the shims already in node_modules #17750.

  • Installing no longer replaces the POSIX bin shims that a newer pnpm wrote in node_modules/.bin.

  • Linking bins is faster for packages that ship large native executables as bins. pnpm now reads only the first 512 bytes of a bin file to find its shebang #17361.

  • pnpm run and pnpm setup no longer clear the visible terminal on Windows when a project path contains non-ASCII characters.

  • pnpm stops scripts and their descendants when it is killed during script startup pnpm/tasks#313.

Engines and runtimes#

  • pnpm install now fails on a workspace project's incompatible engines.pnpm, or on its incompatible engines.node with engineStrict enabled, even when the project's os, cpu, or libc excludes the current platform pnpm/tasks#281.

  • pnpm install now checks the project's engines field when the project is already up to date. A repeat install of a project outside a workspace warns about an incompatible Node.js version, or fails with engineStrict enabled #17751.

  • A workspace project that downloads its own Node.js through devEngines.runtime now has its engines.node checked against that Node.js. Before, pnpm checked it against the shared Node.js version, so engineStrict could reject a project whose scripts run on a compatible runtime pnpm/tasks#300.

  • A repeat pnpm install now runs a full install when the runtimeOnFail setting changes. Before, it printed "Already up to date" and did not install the runtime a project declares in devEngines.runtime pnpm/tasks#303.

  • Fixed missing warnings when a required dependency does not support the current Node.js version.

Other commands and settings#

  • pnpm dist-tag and pnpm unpublish now offer browser-based authentication when the account's two-factor authentication uses a security key. Before, they asked for a one-time password in that case #17832.

  • pnpm login now prints the registry's npm-notice message before the web login URL. Some registries use it to show a code that you type in the browser.

  • pnpm self-update now updates the project's engines.pnpm range along with its pnpm pin, keeping the ^ or ~ operator #17732.

  • pnpm setup and the install script now support PowerShell as the login shell on Linux and macOS. They add PNPM_HOME to PATH in profile.ps1 under $XDG_CONFIG_HOME/powershell or ~/.config/powershell #18026.

  • pnpm setup rejects a PNPM_HOME value that would split the saved PATH pnpm/tasks#315.

  • Relative directory selectors set on config.filter or config.filterProd by an updateConfig hook now resolve from the workspace root even when --dir is passed or pnpm runs from a subdirectory #17906.

  • pnpm now reads the boot document of pnpm-lock.yaml when it is written in lockfile format 13. pnpm then switches to the pnpm version such a project pins.

  • Programmatic install mutations that omit workspace project manifests now resolve locally when a pnpr server is configured pnpm/tasks#59.

  • pnpm now recognizes Capawesome Cloud and RWX as CI environments.

  • The warning about unrecognized settings now marks projectScopedOptionalPeers as a setting of a newer pnpm version.
