pnpm/action-setup v6 v5 v4 changelog breaking changes

💡 Result:

Key breaking changes when moving between major versions of pnpm/action-setup (v4 → v5 → v6): 1) GitHub Actions runtime Node.js version changed to Node 24 - The action’s “runs” environment changed from using Node 20 to using Node 24 between v4 and v5 (and therefore affects v5+). [1] - There are discussions/issues explicitly describing this as breaking for older/self-hosted runners and recommending using v5 (or pinning an older v4 tag) as a workaround. [2] - In the v4...v6 compare view, the “runs” section shows node20 → node24. [3] 2) pnpm v11 support and updated pnpm bootstrap behavior (v6 line) - v6 releases include updates to pnpm (for example, “update pnpm to 11.1.1”). [4] - The main releases page shows v6-era notes like “Added support for pnpm v11” and “Updated the action to use Node.js 24.” [5] 3) Input/README contract adjustments that can break workflows relying on older defaults - cache_dependency_path input type/default documentation changed (v4...v6 compare shows a doc/contract change from “string|string[]” to “string” and notes multiple paths are accepted delimited by newlines). [3] - v4...v6 compare also shows example workflow snippets updated to use actions/checkout@v6 and pnpm/action-setup@v6 (if you had workflow parsing or strict linting around these snippets, that would matter, though it’s more guidance than runtime behavior). [3] 4) v5 → v6 behavior regarding package.json packageManager pinning (reported as a bug) - There’s an open issue stating that “action-setup@v6 does not take the requested pnpm version into account” (i.e., it is not honoring the version specified in the packageManager field in package.json). [6] - This is not described as an intentional breaking change in the official release notes we found, but it is a workflow-relevant behavioral regression/issue when upgrading to v6. [6] Practical upgrade guidance (based on the above): - If you run on older/self-hosted GitHub Actions runners that can’t handle Node 24, expect breakage when moving from v4 → v5 or v6; pin to an earlier v4 sub-version as suggested in the issue thread, or test with a runner that supports Node 24. [2] - Re-validate pnpm version selection logic after upgrading to v6, especially if you rely on package.json “packageManager”: the v6 behavior is reported as not honoring that value. [6] - If you use pnpm/action-setup caching, re-check your cache_dependency_path formatting: it’s documented differently in the v4...v6 compare view (string with multiple paths via newline delimiting). [3] If you want, tell me your current pin (e.g., pnpm/action-setup@v4.x or @v5.x) and how you set pnpm version (version input vs package.json packageManager) and whether you use caching; I can map the above into an exact “what to change” checklist.

Node.js 24 required for pnpm/action-setup@v6, but action defaults to Node 20.

The upgrade to v6 requires Node.js 24 (its runs environment uses node24), but the custom action defaults to node-version: 20.16.0. This causes the action to fail on Node 20 runners. The checking-dependencies.yml workflow already uses Node 24.15.0 with v6; the custom action's default must match. Additionally, v6 has a reported bug where it does not honor the packageManager field in package.json (currently set to pnpm@11.1.2), which may cause unexpected pnpm version selection. Update the default node-version to 24 or higher, and verify pnpm version behavior after upgrading.

In @.github/actions/setup/action.yml at line 13, The action uses
pnpm/action-setup@v6 but the custom action default still sets node-version:
20.16.0 which is incompatible; update the default node-version in action.yml to
Node 24 (>=24.0.0, e.g., 24.15.0 to match checking-dependencies.yml) so the
action runs on the required runtime, and after changing the default verify pnpm
selection behavior (packageManager in package.json / pnpm@11.1.2) because v6 has
a bug that may ignore packageManager—if necessary pin the pnpm version
explicitly or add configuration to enforce packageManager to ensure the expected
pnpm version is used.

pnpm/action-setup v6 release notes

💡 Result:

pnpm/action-setup v6 release notes (from the repo’s official GitHub Releases pages) are available as a series of versioned release entries under the v6 tags. The most recent v6 entry visible in the official releases feed is v6.0.8 (published 2026-05-12), with the following changes: 1) v6.0.8 (2026-05-12) - docs(README): fix cache_dependency_path type (PR #257) [1] - fix: drop patchPnpmEnv so standalone+self-update works on Windows (PR #258) [1] - fix: update pnpm to 11.1.1 (PR #248) [1] 2) v6.0.4 (2026-04-30) - fix: use npm co-located with the action node binary (PR #239) [2] Additional v6 changes are also reflected in the v4...v6 comparison page (including updates to README/examples and caching-related input typing/behavior), which indicates that v6 introduces/updates inputs like cache_dependency_path handling. In that compare view, cache_dependency_path is described as accepting multiple paths delimited by newlines, and the example workflows are updated to use pnpm/action-setup@v6 instead of v4. [3] Notes / where to read the full set of v6 release notes: - Start at the official Releases index for pnpm/action-setup and select the v6.x.y tags. The Releases index is the source of truth for the complete v6 changelog history. [4] If you want, tell me the exact v6 range you care about (e.g., “v6.0.0 through v6.0.8” or “just v6.0.8”), and I’ll summarize only those entries.

pnpm 11.1.2 release date and availability

💡 Result:

No evidence found of a pnpm 11.1.2 release as of 2026-05-14. The latest releases are v11.1.1 (published around 2026-05-12 [1]) and v11.1.0 (published 2026-05-11 [2][3][4]). Official GitHub releases page lists recent tags up to May 12 but no 11.1.2 [3]. npm registry tracks these releases [4], and no sources mention 11.1.2. It is not yet released or available.[2][3][1]

pnpm/action-setup configure pnpm version 11.1.2

💡 Result:

To configure pnpm/action-setup to install pnpm 11.1.2, use the action’s with.version input: steps: - uses: pnpm/action-setup@v6 with: version: 11.1.2 The version input is “Version of pnpm to install” and supports exact versions like 11.1.2 (or version ranges/tags). If you omit version, the action can use the packageManager field from your package.json instead.[1] You may optionally specify run_install if you also want the action to run pnpm install for you; otherwise run pnpm install in a later step.[1]

Configure pnpm version in pnpm/action-setup to match project requirement.

The workflow uses pnpm/action-setup@v6 which installs pnpm 11.1.1 by default, but the project specifies packageManager: pnpm@11.1.2 in package.json. Since pnpm 11.1.2 does not yet exist, the pnpm install --frozen-lockfile step (line 21) will fail due to version mismatch. Either update package.json to use pnpm 11.1.1, or configure the action with with.version: 11.1.2 once that version is released. Alternatively, the action can auto-detect the version from package.json if no version input is specified (allowing proper error messaging when unavailable).

pnpm 11 release notes breaking changes from pnpm 10

💡 Result:

pnpm 11 introduces several breaking changes from v10, primarily documented in the official migration guide [1] and v11.0.0 release notes [2][3]. Key breaking changes include: Node.js requirement: Now requires Node.js 22 or newer; support for v18-21 dropped. pnpm is pure ESM, and standalone exe needs glibc 2.27+ [3][2][4]. Configuration changes [1]: - No longer reads config from package.json#pnpm; move to pnpm-workspace.yaml. -.npmrc limited to auth/registry; other settings (hoist-pattern, node-linker, etc.) to pnpm-workspace.yaml (camelCase keys). - npm_config_* env vars ignored; use pnpm_config_*. - Deprecated build settings (onlyBuiltDependencies, etc.) removed; use allowBuilds [3][2]. - Package manager settings consolidated to pmOnFail: 'download'|'ignore'|'warn'|'error'. - Renames: allowNonAppliedPatches -> allowUnusedPatches; auditConfig.ignoreCves -> auditConfig.ignoreGhsas. Store upgraded to v11: SQLite index.db replaces JSON files; incompatible with v10 stores (clear or migrate) [3][2][5]. Global installs: Isolated in {pnpmHomeDir}/global/v11/{hash}/ with own package.json/node_modules/pnpm-lock.yaml. pnpm install -g (no args) removed; use pnpm add -g [3][2]. pnpm link changes: No global store resolution; only relative/absolute paths. --global removed (use pnpm add -g.); no-arg pnpm link removed [1][6]. Removed commands: pnpm server; npm passthrough (publish, login, etc.) now native, some like access, edit removed [3][2]. Lockfile: patchedDependencies simplified to selector -> hash; auto-migrated [5]. Script shadowing: Scripts named clean/setup/deploy/rebuild run script, not built-in; use pnpm pm [1]. Security defaults: minimumReleaseAge=1440 (1 day), blockExoticSubdeps=true, strictDepBuilds=true [3][2]. A codemod assists migration: pnpx codemod run pnpm-v10-to-v11 [1]. Full details: https://pnpm.io/migration [1], https://github.com/pnpm/pnpm/releases/tag/v11.0.0 [2], https://pnpm.io/blog/releases/11.0 [3].

Migrate deprecated pnpm configuration to pnpm 11 format.

The pnpm-lock.yaml has been regenerated to v9.0 (pnpm 11 format), but package.json still contains deprecated configuration that is no longer supported in pnpm 11:

  • ignoredBuiltDependencies and onlyBuiltDependencies must be migrated to the new allowBuilds configuration
  • Node.js requirement must be explicitly set to 22+ in the engines field (pnpm 11 no longer supports Node.js v18-21)

These deprecated options will cause failures when running pnpm commands. Use the pnpm v10→v11 migration codemod (pnpx codemod run pnpm-v10-to-v11) to complete the migration.

In `@package.json` at line 6, Update package.json to remove deprecated pnpm v10
fields and adopt pnpm v11 format: replace any ignoredBuiltDependencies and
onlyBuiltDependencies entries with the new allowBuilds configuration (mapping
allowed package patterns or booleans accordingly) and set the engines.node field
to ">=22" (or "22.x" per project policy) so Node.js requirement is explicit for
pnpm 11; also keep packageManager set to "pnpm@11.1.2" and run the pnpm v10→v11

ESLint 10.0 release notes breaking changes migration guide

💡 Result:

ESLint 10.0 release notes / breaking changes and the official migration guide are here: 1) Official migration guide (v9.x → v10.x) https://eslint.org/docs/latest/use/migrate-to-10.0.0 [1] 2) Official release notes for v10.0.0 https://eslint.org/blog/2026/02/eslint-v10.0.0-released/ [2] Key breaking changes called out in the migration guide (high-signal items) A) Node.js version support dropped ESLint v10.0.0 no longer supports Node.js versions < v20.19.0 (and also drops v21.x and v23.x); the migration guide says to upgrade to Node.js v20.19.0 or later [1][3]. B) “Old config format” no longer supported; flat config required The v10 migration guide states the legacy config system is removed (i.e., old eslintrc format is no longer supported) and points you to use flat config (eslint.config.) [1]. The migration guide summary also calls out removing the eslintrc format [1][3]. C) New configuration file lookup algorithm In ESLint v9 there was an alternate behavior guarded by a feature flag; in v10.0.0, the behavior is the default. The migration guide describes that config lookup now starts from the directory of each linted file and searches upward to the filesystem root (instead of starting from the current working directory) and that the v10_config_lookup_from_file flag was removed [1]. D) Removed feature for eslintrc config lookup behavior flag Attempting to use v10_config_lookup_from_file now results in an error (because the flag was removed) [1]. E) Rule/behavior & API breaking changes (examples listed in the migration guide) The migration guide lists multiple other breaking/API changes, including (among others) removal of the nodeType property in LintMessage objects [1], JSX references now being tracked [1], and changes around fixer APIs requiring string text arguments [1]. How to migrate (practical steps to follow) - Upgrade Node.js to a supported version (>= v20.19.0) before running ESLint 10 [1]. - Ensure you are using flat config (eslint.config.) and remove any legacy eslintrc configuration usage [1]. - If you previously relied on the v9 config lookup behavior / feature flag, update to the new lookup algorithm (start from each linted file’s directory) [1]. - Then run the official migration guide’s checklist/sections to address any remaining listed breaking changes in your specific setup [1].

Add engines field to enforce Node.js >= v20.19.0 for ESLint 10.3.0 compatibility.

The repository has already properly migrated to ESLint's flat config format (eslint.config.mts) and uses @eslint/compat correctly for plugin compatibility. However, ESLint 10.3.0 requires Node.js >= v20.19.0, and this constraint should be explicitly documented in package.json via an engines field. Without it, developers using older Node.js versions may encounter runtime errors. Add to packages/app/package.json:

"engines": {
  "node": ">=20.19.0"
}

In `@packages/app/package.json` at line 71, Add an "engines" entry to
packages/app/package.json to require Node.js >=20.19.0 so ESLint 10.3.0 runs
correctly; locate the existing "eslint": "^10.3.0" dependency in package.json
and add an "engines" object with "node": ">=20.19.0" to enforce the minimum Node
version for contributors and CI.
