GitHub Actions Node.js 24 runner migration Node.js 20 removal fall 2026 actions/stale v10 v11 compatibility

💡 Result:

GitHub Actions has undergone a mandatory migration from Node.js 20 to Node.js 24 during 2026 [1][2]. Key Migration Details: - Node.js 24 became the default runtime for GitHub Actions runners on June 16, 2026 [1][3]. - Node.js 20 removal is scheduled for the fall of 2026 [1][2]. After this removal, actions still configured to use Node.js 20 will fail [1][4]. - While temporary opt-out mechanisms (e.g., ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true) were available following the June 16 default-switch, these are strictly limited and will cease to function once Node.js 20 support is entirely removed from the runners [1]. Compatibility with actions/stale: - actions/stale v10.0.0 was the first release to upgrade the runtime from Node.js 20 to Node.js 24 [5][6]. - Compatibility with this version requires runners to be version v2.327.1 or later [5][6]. - actions/stale v11.0.0, released on July 28, 2026, further migrated the action to ESM (ECMAScript modules) and updated dependencies [7][8]. Users are advised to use the latest v11.x versions to ensure full compatibility with the Node.js 24 runtime environment [7][9]. Recommendation: Users should audit their workflows to ensure all actions are updated to versions that support Node.js 24 [1]. For actions/stale specifically, upgrading to v11.0.0 or later is recommended to maintain support and benefit from updated dependencies and ESM implementation [7].

Update actions/stale to v11.0.0.

actions/stale@v9 uses Node.js 20. Node.js 20 support will be removed from GitHub-hosted runners in fall 2026. actions/stale@v11.0.0 uses Node.js 24 and requires runner v2.327.1 or later.

Proposed fix 
-      - uses: actions/stale@v9
+      - uses: actions/stale@v11.0.0
