vpnpm 12.8.2 · today

pnpm 12.8.2 fixes a startup crash on Linux ppc64le and UnknownIssuer errors on systems without CA certificates. pnpm run no longer installs before every script on CI when autoDedupe is enabled, and resolution and hoisted installs on macOS are faster.

Patch Changes

Platforms and environments

Fixed pnpm crashing on startup on Linux ppc64le #16380.
Fixed installs failing with UnknownIssuer on Linux systems without CA certificates, such as node:24-slim, when NODE_EXTRA_CA_CERTS is set. The extra certificates now extend the bundled CA roots #16365.
pnpm now creates its store operation locks and other per-user lock files in $XDG_RUNTIME_DIR when it points to a directory only the user can write to. Otherwise, pnpm still uses /tmp on Linux and macOS. Sandboxes that block writes to /tmp can point XDG_RUNTIME_DIR at a writable directory #16390.
POSIX bin shims and the pnpm, pn, pnpx, and pnx launchers now run inside a Nix build, where the system default path holds none of the utilities they call. Installing again replaces the shims already in node_modules #16377.
In a project that pins another pnpm version, pnpm now passes a command with an option it does not know to the pinned version. Before, pnpm rejected the option before switching, so pnpm install --auto-dedupe failed with "Unknown option" even though the pinned pnpm supports it #16353.

Installing and resolving dependencies

pnpm install --frozen-lockfile now fails when Cargo.lock does not satisfy a dependency requirement in Cargo.toml. The error names the crate and the version the lockfile holds #16355.
pnpm install returns "Already up to date" again in a workspace with injected workspace dependencies and a shared lockfile. Since 12.7.0 every repeat install in such a workspace ran the full install and copied the injected projects again.
With injectWorkspacePackages: true, a fresh pnpm install now records a workspace dependency as link: when its injected copy differs from the project only by an optional peer that peer-dependent dedupe merges. It was recorded as a peer-suffixed file: copy #16354.
pnpm dedupe --check now passes right after pnpm dedupe when deduplication merges variants of a package that differ only in their peers. A lockfile key whose peer suffix named a merged variant now names the variant that replaced it #16356.
When minimumReleaseAge hides the version that latest points to, pnpm now falls back to a prerelease of the same major before a stable version of an older major. A stable version of the same major is still preferred. Before, while a new 1.0.0 was too new, latest fell back to an old 0.0.1 even though 1.0.0-beta.4 had been latest until then #16388.
Git-hosted dependencies now respect pmOnFail. If it is set to anything other than download, a git-hosted dependency that pins a pnpm version is prepared by the running pnpm, and pnpm does not download the pinned version #16376.
pnpmfile hooks such as readPackage now run once for a dependency that several packages request at the same time. They could run twice for it before.
childConcurrency now defaults to 5, the documented value. It used to be capped at 4 and to follow the host's CPU count.

Running scripts

pnpm run and pnpm exec no longer install dependencies before every script on CI when autoDedupe is enabled. pnpm install --frozen-lockfile now keeps the deduplication record left by an earlier install #16374.
On macOS and Linux, lifecycle scripts and pnpm run now always get PATH from the PATH variable. When the environment also held a Path variable, a script sometimes got Path's value, and failed with node: not found #16308.
pnpm run now exits after a SIGTERM in a container where pnpm is PID 1 and the script runs pnpm again, as "start": "pnpm serve" does. Since 12.6.0 it kept waiting after the script had shut down, until the container runtime killed it.

Other commands and settings

pnpm config get globalShims, pnpm shim list, and global installs no longer read globalShims from a project's pnpm-workspace.yaml. Only the global config file, the pnpm home's own pnpm-workspace.yaml, and PNPM_CONFIG_GLOBAL_SHIMS set it, so a repository cannot choose which globally installed packages get project-aware shims.
pnpm config set --location=project refuses a machine-level setting such as stateDir or scope with ERR_PNPM_CONFIG_SET_NOT_A_PROJECT_SETTING, which names where the setting belongs. pnpm config delete still clears such a key from a project's pnpm-workspace.yaml.
pnpm deploy no longer fails with ERR_PNPM_DEPLOY_AMBIGUOUS_PEER in a workspace with injectWorkspacePackages: true when a workspace package lists its peer dependency as a dev dependency too #16375.
pnpm deploy no longer copies the workspace root's packageManager and devEngines.packageManager fields into the deployed package.json #16403.
pnpm publish now includes bare README files and README files with Markdown extensions such as readme.markdown in registry metadata #12704.
pnpm store prune now removes the packages that only expired pnpm dlx cache entries used. They were left in the store until the next pnpm store prune #16383.

Performance

Sped up dependency resolution in large workspaces, and when many dependencies request different ranges of the same package. Resolution also uses less memory.
Sped up pnpm install with nodeLinker: hoisted on macOS when the lockfile is re-resolved, such as with autoDedupe enabled #16397.
Sped up extracting package tarballs.
pnpm install without --frozen-lockfile is faster on some machines in projects with a pnpm-workspace.yaml. Those installs linked with one worker thread per core, half of what a frozen install uses.
On Windows, warm pnpm install --frozen-lockfile runs are 4-5% faster on 4- and 8-core machines. pnpm now links with one worker thread per core on Windows, between 4 and 16. This changes frozen installs and installs in projects without a pnpm-workspace.yaml on machines with 3 to 15 cores.
