<title>Deprecation of Node 20 on GitHub Actions runners - GitHub Changelog</title> https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/ Deprecation of Node 20 on GitHub Actions runners - GitHub Changelog September 19, 2025 • 1 minute read # Deprecation of Node 20 on GitHub Actions runners Editor’s note (August 25, 2026): Updated the Node20 removal date to September 23rd, 2026. Editor’s note (February 25, 2026): Updated the migration date to June of 2026. Editor’s note (May 19, 2026): Updated the migration date to June 16th, 2026. Node20 will reach end-of-life (EOL) in April of 2026. As a result we have started the deprecation process of Node20 for GitHub Actions. We plan to migrate all actions to run on Node24 in the fall of 2025. The newest GitHub runner (v2.328.0) now supports both Node20 and Node24 and uses Node20 as the default version. If you’d like to test Node24 ahead of time, set `FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true` as an `env` in your workflow or as an environment variable on your runner machine to force the use of Node24. Beginning on June 16th, 2026, runners will begin using Node24 by default. To opt out of this and continue using Node20 after this date, set `ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true` as an `env` in your workflow or as an environment variable on your runner machine. This will only work until we upgrade the runner and remove Node20 on September 23rd, 2026. ### Removal of operating system support with Node24 Node24 is incompatible with macOS 13.4 and lower versions. Node 24 does not have official support for ARM32, so self-hosted runners on ARM32 will no longer be supported after Node 20 deprecation. To find out more about the OS versions we support and self-hosted runner architectures, please read our documentation. ### What you need to do For Actions maintainers: Update your actions to run on Node24 instead of Node20 (Actions configuration settings) For Actions users: Update your workflows with latest versions of the actions that run on Node24 (Using versions for Actions) Join the discussion within GitHub Community. <title>[All OS] Default Node.js version will be changed from 20 to 22 and Node.js 20 will be removed from runner images</title> GitHub issue 14029 in actions/runner-images (link omitted to avoid creating a cross-reference) # [All OS] Default Node.js version will be changed from 20 to 22 and Node.js 20 will be removed from runner images - State: closed - Author: v-GeorgyPuzakov - Created: 2026-05-11T19:30:47Z - Updated: 2026-06-01T16:33:09Z - Repository: actions/runner-images - Number: `#14029` - Assignees: v-GeorgyPuzakov ## Labels - Area: Node.js - OS: macOS - OS: Ubuntu - OS: Windows - Announcement --- ### Breaking changes Node.js 20 has reached end-of-life on April 30, 2026. Starting with the next image releases, Node.js 20 will be removed from the toolcache on all runner images. The default Node.js version will be updated to Node.js 22 (Maintenance LTS) on images where Node.js 20 was the default. Node.js 20 reached end-of-life on April 30, 2026. Starting with the next image releases: 1. Node.js 20 will be removed from the toolcache on all runner images. It will no longer be pre-installed. The default Node.js version will be updated to 22 (Maintenance LTS) on images where Node.js 20 was previously the default. 2. After this change, only Node.js 22 and Node.js 24 will remain pre-installed in the toolcache. ### Target date This change will be rolled out beginning May 19, 2026 and will complete by May 26, 2026. ### The motivation for the changes Node.js 20 transitioned to end-of-life on 2026-04-30. Keeping an EOL runtime as the default version on runner images poses security risks and causes confusion for users. Node.js 22 (Maintenance LTS) is the next supported version and is already the default on macos-15, windows-2025, and windows-2025-vs2026 images. This change aligns the remaining images with the same supported baseline. ### Possible impact **Node.js 20 will no longer be available in the toolcache.** Workflows that rely on `node` or `npm` commands without explicitly specifying a version via actions/setup-node will now use Node.js 22 instead of Node.js 20 on affected images. **If your project requires Node.js 20, you must use `actions/setup-node` to install it.** Since Node.js 20 will no longer be pre-installed, `actions/setup-node` will download it on demand, which may add some time to your workflow. ### Platforms affected - [x] Azure DevOps - [x] GitHub Actions ### Runner images affected - [x] Ubuntu 22.04 - [x] Ubuntu 24.04 - [x] Ubuntu 26.04 - [x] Ubuntu Slim - [x] macOS 14 - [x] macOS 14 Arm64 - [x] macOS 15 - [x] macOS 15 Arm64 - [x] macOS 26 - [x] macOS 26 Arm64 - [x] Windows Server 2022 - [x] Windows Server 2025 - [x] Windows Server 2025 with Visual Studio 2026 ### Mitigation ways Use NodeJS 22 or 24 instead NodeJS 20 ## Timeline - v-GeorgyPuzakov added label "Area: Node.js" - v-GeorgyPuzakov added label "OS: macOS" - v-GeorgyPuzakov added label "OS: Ubuntu" - v-GeorgyPuzakov added label "OS: Windows" - v-GeorgyPuzakov added label "Announcement" - someone unsubscribed - Referenced by issue `#13833`: ubuntu-latest default Node.js 20.20.2 unsupported **MikeMcC399** commented on 2026-05-12T07:33:06Z: > - https://github.com/actions/runner-images/issues/13833 previously referred to this issue for Ubuntu only - MikeMcC399 marked_as_duplicate - daxpedda subscribed - MasterZydra subscribed - jjspace subscribed - v-GeorgyPuzakov was assigned - Referenced by PR `#8997`: [GITHUB] build.yml: Update GitHub dependencies - Referenced by PR `#14046`: [All OS] Default Node.js version changed from 20 to 22.

The file versions-manifest.json contains the list of available and released versions. > Caution: this is prepared for and only permitted for use by actions `runner-images` and `setup-node` action. **Status**: Currently under development and in use for beta and preview actions. This repo is undergoing rapid changes. Latest of LTS versions will be installed on the runner-images images. Other versions will be pulled JIT using the `setup-node` action. ## Adding new versions We are trying to prepare packages for new versions of Node.js as soon as they are released. Please open an issue in actions/runner-images if any versions are missing. ## Support Notification Policy Beginning **approximately six months prior** to the removal of a Node.js version from the versions-manifest.json file, a pinned issue will be created in the setup-node repository. This pinned issue will provide important details about the upcoming end of support, including the specific date, as well as any other notes, relevant updates or alternatives. We encourage users to regularly check pinned issues for updates on tool versions they are using for maximum transparency, security, performance and overall compatibility with their projects. ## Contribution Contributions are welcome!

The approach uses feature flags for a phased rollout, similar to the previous Node 16 to Node 20 migration. ## Key Features - Phased migration with clear transition points - User controls via environment variables - Feature flags for controlled rollout - Compatibility handling for Linux ARM32 - Informative messaging to guide users through the transition ## Migration Phases ### Phase 1: Node 20 Default Initially Node 20 remains the default: - Default: Node 20 - Opt-in to Node 24: Set `FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true` ### Phase 2: Node 24 Default When the `actions.runner.usenode24bydefault` flag is enabled: - Default: Node 24 - Temporary fallback to Node 20: Set `ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true` - Informational message appears explaining Node 20 deprecation and opt-out options ### Phase 3: Node 24 Required When the `actions.runner.requirenode24` flag is enabled: - All actions use Node 24 - No opt-out options available ## Environment Variables The migration uses two environment variables: - `FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true`: Opt into Node 24 during Phase 1 - `ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true`: Fall back to Node 20 during Phase 2 These can be set at either the workflow level (in YAML) or runner level (system environment). Workflow settings override runner settings to ensure job-specific control. ## Implementation Details ### Core Components The migration strategy includes: 1. **Centralized Constants** - Version identifiers: `Node20` and `Node24` - Environment variable definitions - Feature flag definitions 2. **Version Selection Logic** - Logic that factors in: - Current migration phase - Environment variables (workflow and runner) - Action metadata - Platform compatibility 3. **User Feedback** - Warning when conflicting settings are detected - Helpful messages during Phase 2 explaining the Node version change - Clear instructions for temporarily using Node 20 when needed 4. **Platform Compatibility** - Special handling for Linux ARM32 where Node 24 isn&`#39`;t supported - Automatic fallback to Node 20 with explanatory message - Multiple safeguards to ensure consistent behavior ## Testing & Compatibility Tests cover: - ... feature flag and environment variable ... - All migration phases - Environment variable precedence scenarios - Platform-specific behavior (including ARM32) - Conflict detection Backward compatibility is maintained through: - Zero-change workflow execution during migration - Clear warning messages for configuration issues - Automatic fallbacks on unsupported platforms - Feature-flagged rollout for controlled deployment ## Node ... ### ... | true | - | - | true | Node 20 | Important edge case: AllowUnsecure=true always takes precedence in Phase 2 | | - | true | true | - | Node 20 | Important edge case: AllowUnsecure=true always takes precedence in Phase 2 | ### Phase 3: Node 24 Required (requireNode24=true) In Phase 3, the environment variables are ignored and Node 24 is always used. ### Notable Edge Cases #### 1. Mixed-Source Variables (Workflow vs System) When variables come from different sources, each is evaluated independently: **Example:** ForceNode24=false (Workflow), AllowUnsecure=true (System) - The workflow explicitly opts out of Node 24 by setting ForceNode24=false - The system has AllowUnsecure=true - Result: Node 20 is used (workflow&`#39`;s opt-out from Node 24 is respected) **Example:** AllowUnsecure=false (Workflow), ForceNode24=true (System) - The workflow explicitly disallows Node 20 by setting AllowUnsecure=false - The system has ForceNode24=true - Result: Node 24 is used (system&`#39`;s ForceNode24 is respected since workflow doesn&`#39`;t override it) **Key E…[truncated]

No changes to action inputs, outputs, or behavior. ## Breaking changes in V6 The V6 edition of the action includes: - **Upgraded Node.js runtime from node20 to node24** > Make sure your runner is on version v2.327.1 or later to ensure compatibility with this release. See Release Notes - **Go toolchain** - Supports both `go` and `toolchain` directives in `go.mod`. If the `toolchain` directive is present, its version is used; otherwise, the action falls back to the `go` directive. - **Cache key update** - By default, the cache key for Go modules is based on `go.mod`. To use `go.sum`, configure the `cache-dependency-path` input. See full release notes on the releases page. ## Usage See action.yml. ```yaml - uses: actions/setup-go@v7 with: # Version or version range of Go to use go-version: &`#39`;1.23&`#39`; # Path to go.mod, go.work, .go-version, or .tool-versions file # Note: if both go-version and go-version-file are provided, go-version takes precedence. go-version-file: &`#39`;go.mod&`#39`; # Set this option if you want the action to check for the latest available version # Default: false check-latest: false # GitHub token for authentication token: ${{ github.token }} # Used to specify whether caching is needed. # Default: true cache: true # Path to dependency files for caching cache-dependency-path: &`#39`;go.sum&`#39`; # Architecture to install (auto-detected if not specified) architecture: &`#39`;x64&`#39`; # Custom base URL for Go downloads (e.g., for mirrors) go-download-base-url: &`#39`;&`#39`; ``` **Basic:** ```yaml steps: - uses: actions/checkout@v7 - uses: actions/setup-go@v7 with: go-version: &`#39`;1.25&`#39`; # The Go version to download (if necessary) and use. - run: go run hello.go ``` **Version resolution behavior:** The action resolves the requested version in the following order: 1. **Local cache** - Checks the local tool cache for a matching semver version. 2. **go-versions repository** - If the requested version isn’t available in the tool cache, it pulls the version manifest from the `main` branch of the go-versions repository. 3. **Direct download** - If that lookup misses or fails, it will fall back to downloading directly from the official Go distribution site. To change the default behavior, please use the check-latest input. > **Note**: The `setup-go` action uses executable binaries built by the Go team and does not build Go binaries from source code. ## Supported version syntax The `go-version` input supports the following syntax: - Specific versions: `1.25`, `1.24.11`, `1.24.0-rc.1`, `1.23.0-beta.1` - SemVer version range syntax: `^1.25.1`, `~1.24.1`, `>=1.25.0-rc.1`, `<1.25.0`, `>=1.22.0 <1.24.0` - Aliases: `stable`, `oldstable` - Wildcards: `1.25.x`, `1.x` For details on Semantic Versioning, see the semver package documentation. > **Note**: Due to the peculiarities of YAML parsing, it is recommended to wrap the version in single quotation marks: > > ```yaml > go-version: &`#39`;1.20&`#39`; > ``` > > The recommendation is based on the YAML parser&`#39`;s behavior, which interprets non-wrapped values as numbers and, in the case of version `1.20`, trims it down to `1.2`, which may not be very obvious.

See full release notes on the releases page. ## Usage See action.yml. ```yaml - uses: actions/setup-go@v7 with: # Version or version range of Go to use go-version: &`#39`;1.23&`#39`; # Path to go.mod, go.work, .go-version, or .tool-versions file # Note: if both go-version and go-version-file are provided, go-version takes precedence. go-version-file: &`#39`;go.mod&`#39`; # Set this option if you want the action to check for the latest available version # Default: false check-latest: false # GitHub token for authentication token: ${{ github.token }} # Used to specify whether caching is needed. # Default: true cache: true # Path to dependency files for caching cache-dependency-path: &`#39`;go.sum&`#39`; # Architecture to install (auto-detected if not specified) architecture: &`#39`;x64&`#39`; # Custom base URL for Go downloads (e.g., for mirrors) go-download-base-url: &`#39`;&`#39`; ``` **Basic:** ```yaml steps: - uses: actions/checkout@v7 - uses: actions/setup-go@v7 with: go-version: &`#39`;1.25&`#39`; # The Go version to download (if necessary) and use. - run: go run hello.go ``` **Version resolution behavior:** The action resolves the requested version in the following order: 1. **Local cache** - Checks the local tool cache for a matching semver version. 2. **go-versions repository** - If the requested version isn’t available in the tool cache, it pulls the version manifest from the `main` branch of the go-versions repository. 3. **Direct download** - If that lookup misses or fails, it will fall back to downloading directly from the official Go distribution site. To change the default behavior, please use the check-latest input. > **Note**: The `setup-go` action uses executable binaries built by the Go team and does not build Go binaries from source code. ## Supported version syntax The `go-version` input supports the following syntax: - Specific versions: `1.25`, `1.24.11`, `1.24.0-rc.1`, `1.23.0-beta.1` - SemVer version range syntax: `^1.25.1`, `~1.24.1`, `>=1.25.0-rc.1`, `<1.25.0`, `>=1.22.0 <1.24.0` - Aliases: `stable`, `oldstable` - Wildcards: `1.25.x`, `1.x` For details on Semantic Versioning, see the semver package documentation. > **Note**: Due to the peculiarities of YAML parsing, it is recommended to wrap…[truncated] <title>Fix Node.js version in action.yml · Pull Request `#691` · actions/setup-go</title> GitHub pull request 691 in actions/setup-go (link omitted to avoid creating a cross-reference) # Pull Request: actions/setup-go `#691` - Repository: actions/setup-go | Set up your GitHub Actions workflow with a specific version of Go | 2K stars | TypeScript ## Fix Node.js version in action.yml - Author: [`@ccoVeille`](https://github.com/ccoVeille) - Association: CONTRIBUTOR - State: merged - Source branch: node24-action - Target branch: main - Mergeable: unknown - Commits: 1 - Additions: 1 - Deletions: 1 - Changed files: 1 - Created: 2025-12-07T15:24:31Z - Updated: 2026-01-08T20:00:12Z - Closed: 2026-01-07T15:26:13Z - Merged: 2026-01-07T15:26:13Z - Merged by: [`@HarithaVattikuti`](https://github.com/HarithaVattikuti) **Description:** It looks like the Node.js version specified in action.yml was left behind when we upgraded the project to Node.js 24.

<title>Deprecation of Node 20 on GitHub Actions runners - GitHub Changelog</title> https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/ Deprecation of Node 20 on GitHub Actions runners - GitHub Changelog September 19, 2025 • 1 minute read # Deprecation of Node 20 on GitHub Actions runners Editor’s note (August 25, 2026): Updated the Node20 removal date to September 23rd, 2026. Editor’s note (February 25, 2026): Updated the migration date to June of 2026. Editor’s note (May 19, 2026): Updated the migration date to June 16th, 2026. Node20 will reach end-of-life (EOL) in April of 2026. As a result we have started the deprecation process of Node20 for GitHub Actions. We plan to migrate all actions to run on Node24 in the fall of 2025. The newest GitHub runner (v2.328.0) now supports both Node20 and Node24 and uses Node20 as the default version. If you’d like to test Node24 ahead of time, set `FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true` as an `env` in your workflow or as an environment variable on your runner machine to force the use of Node24. Beginning on June 16th, 2026, runners will begin using Node24 by default. To opt out of this and continue using Node20 after this date, set `ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true` as an `env` in your workflow or as an environment variable on your runner machine. This will only work until we upgrade the runner and remove Node20 on September 23rd, 2026. ### Removal of operating system support with Node24 Node24 is incompatible with macOS 13.4 and lower versions. Node 24 does not have official support for ARM32, so self-hosted runners on ARM32 will no longer be supported after Node 20 deprecation. To find out more about the OS versions we support and self-hosted runner architectures, please read our documentation. ### What you need to do For Actions maintainers: Update your actions to run on Node24 instead of Node20 (Actions configuration settings) For Actions users: Update your workflows with latest versions of the actions that run on Node24 (Using versions for Actions) Join the discussion within GitHub Community. <title>09/2025 - GitHub Changelog</title> https://github.blog/changelog/month/09-2025/page/3/ 09/2025 - GitHub Changelog # 09/2025 ### GitHub Copilot app modernization is now generally available for Java and .NET GitHub Copilot app modernization is now generally available for Java and .NET projects.

On June 30th 2024, we will change the default from Node16 to Node20. To opt out of this and continue using Node16 while it is still available in the runner, you can choose to set `ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true` We will then continue to monitor Node16 usage and will communicate a timeline for the removal of Node16 at the start of October, based on the volume of continued use. This means that customers who use the environment variable to continue to use Node16 now have until October to complete their migrations.

Our plan is to transition all actions to run on Node 20 by Spring 2024. We will actively monitor the migration&`#39`;s progress and gather community feedback before finalizing the transition date. Starting October 23rd, workflows containing actions running on Node 16 will display a warning to alert users about the upcoming migration. ### For Actions maintainers Modify your actions to run on Node 20 instead of Node 16. For guidance, refer to the Actions configuration settings. ### For Actions users Ensure your workflows use the latest versions of actions that are running on Node 20. For more information, see Using Versions for Actions. ### For self-hosted runner administrators: Update your self-hosted runners to runner version v2.308.0 or later to ensure compatibility with Node 20 actions. <title>End of life for Actions Node16 - GitHub Changelog</title> https://github.blog/changelog/2024-09-25-end-of-life-for-actions-node16/ End of life for Actions Node16 - GitHub Changelog September 25, 2024 • 1 minute read # End of life for Actions Node16 Following our change to default customers to use Node20, Node16 will reach end of life in the Actions runner on November 12, 2024. From November 12 onward, we will no longer include Node16 in the Actions runner and customers will no longer be able to use Node16 Actions or operating systems that do not support Node20. To prevent disruption to your Actions workflows, if you’re an Actions maintainer, update your actions to run on Node20 instead of Node16. If you’re an Actions user, update your workflows with latest versions of the actions, which run on Node20. Learn more about Actions configuration settings or using versions for Actions.

The approach uses ... flags for a ... rollout, similar to the previous Node 16 to Node 2 ... . ## Key Features - Phased migration with clear transition points - User controls via environment variables - Feature flags for controlled rollout - Compatibility handling for Linux ARM32 - Informative messaging to guide users through the transition ## Migration Phases ### Phase 1: Node 20 Default Initially Node 20 remains the default: - Default: Node 20 - Opt-in to Node 24: Set `FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true` ### Phase 2: Node 24 Default When the `actions.runner.usenode24bydefault` flag is enabled: - Default: Node 24 - Temporary fallback to Node 20: Set `ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true` - Informational message appears explaining Node 20 deprecation and opt-out options ### Phase 3: Node 24 Required When the `actions.runner.requirenode24` flag is enabled: - All actions use Node 24 - No opt-out options available ## Environment Variables The migration uses two environment variables: - `FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true`: Opt into Node 24 during Phase 1 - `ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true`: Fall back to Node 20 during Phase 2 These can be set at either the workflow level (in YAML) or runner level (system environment). Workflow settings override runner settings to ensure job-specific control. ## Implementation Details ### Core Components The migration strategy includes: 1. **Centralized Constants** - Version identifiers: `Node20` and `Node24` - Environment variable definitions - Feature flag definitions 2. **Version Selection Logic** - Logic that factors in: - Current migration phase - Environment variables (workflow and runner) - Action metadata - Platform compatibility 3. **User Feedback** - Warning when conflicting settings are detected - Helpful messages during Phase 2 explaining the Node version change - Clear instructions for temporarily using Node 20 when needed 4. **Platform Compatibility** - Special handling for Linux ARM32 where Node 24 isn&`#39`;t supported - Automatic fallback to Node 20 with explanatory message - Multiple safeguards to ensure consistent behavior ## Testing & Compatibility Tests cover: - Various feature flag and environment variable ... - All migration phases - Environment variable precedence scenarios - Platform-specific behavior (including ARM32) - Conflict detection Backward compatibility is maintained through: - Zero-change workflow execution during migration - ... - Feature-flagged rollout for ... deployment ## ... ### ... | true | - | - | true | Node 20 | Important edge case: ...

Mixed-Source Variables (Workflow vs System) When variables come from different sources, each is evaluated independently: **Example:** ForceNode24=false (Workflow), AllowUnsecure=true (System) - The workflow explicitly opts out of Node 24 by setting ForceNode24=false - The system has AllowUnsecure=true - Result: Node 20 is used (workflow&`#39`;s opt-out from Node 24 is respected) **Example:** AllowUnsecure=false (Workflow), ForceNode24=true (System) - The workflow explicitly disallows Node 20 by setting AllowUnsecure=false - The system has ForceNode24=true - Result: Node 24 is used (system&`#39`;s ForceNode24 is respected since workflow doesn&`#39`;t override it) **Key Edge Case in Phase 2:** When both variables are true (from any sources) - If ForceNode24=true (Workflow) and AllowUnsecure=true (System) - Or ForceNode24=true (System) and…[truncated] <title>Add Node.js 20 deprecation warning annotation (Phase 1) · Pull Request `#4242` · actions/runner</title> GitHub pull request 4242 in actions/runner (link omitted to avoid creating a cross-reference) Adds a deprecation warning annotation for Node.js 20 actions as part of the Node 20 → Node 24 migration Phase 1 (see `#3948`). ...

On linux-arm32 we can&`#39`;t do that since there&`#39`;s no node24 binary, so instead we show a deprecation warning and keep them on node20 for now. Added two new feature flags for the arm32 side: - `actions_runner_deprecate_linux_arm32` - warns that arm32 is going away, keeps running on node20 - `actions_runner_kill_linux_arm32` - for when we actually want to stop supporting it, fails the step Also split the tracking so upgraded-to-node24 actions and still-on-node20 actions get separate annotations instead of lumping them together.

Upgrade the active setup-go step to Node 24.

actions/setup-go@v5 targets Node 20. GitHub’s Node 24 enforcement forces Node 20 actions to run on Node 24 and emits a deprecation annotation, so this step will not fail to start. Upgrade to actions/setup-go@v6 to use Node 24 directly and remove the warning.
