-# V3
+## Breaking changes in V6
 
-The V3 edition of the action offers:
+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](https://github.com/actions/runner/releases/tag/v2.327.1)
 
-- Adds `GOBIN` to the `PATH`
+- **Go toolchain**
-- Proxy support
+  - 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.
-- Check latest version
-- Caching packages dependencies
-- stable and oldstable aliases
-- Bug Fixes (including issues around version matching and semver)
 
-The action will first check the local cache for a version match. If a version is not found locally, it will pull it from the `main` branch of the [go-versions](https://github.com/actions/go-versions/blob/main/versions-manifest.json) repository. On miss or failure, it will fall back to downloading directly from [go dist](https://storage.googleapis.com/golang). To change the default behavior, please use the [check-latest input](#check-latest-version).
+- **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.
 
-**Note:** The `setup-go` action uses executable binaries which are built by Golang side. The action does not build golang from source code.
+See full release notes on the [releases page](https://github.com/actions/setup-go/releases).

-  - uses: actions/checkout@v3
-  - uses: actions/setup-go@v3
-    with:
-      go-version: '1.18.0-rc.1' # The Go version to download (if necessary) and use.

-  - uses: actions/checkout@v3
-  - uses: actions/setup-go@v3
-    with:
-      go-version: '1.16.0-beta.1' # The Go version to download (if necessary) and use.
-  - run: go version
-```
-
-# Usage
-
-See [action.yml](action.yml)
-
-## Basic
-
-```yaml
-steps:
-  - uses: actions/checkout@v3
-  - uses: actions/setup-go@v3
-    with:
-      go-version: '1.16.1' # The Go version to download (if necessary) and use.
-  - run: go run hello.go
-```
-
-
-## Check latest version
-
-The `check-latest` flag defaults to `false`. Use the default or set `check-latest` to `false` if you prefer stability and if you want to ensure a specific Go version is always used.
-
-If `check-latest` is set to `true`, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, a Go version will then be downloaded. Set `check-latest` to `true` if you want the most up-to-date Go version to always be used.
-
-> Setting `check-latest` to `true` has performance implications as downloading Go versions is slower than using cached versions.
-
-```yaml
-steps:
-  - uses: actions/checkout@v3
-  - uses: actions/setup-go@v3
-    with:
-      go-version: '1.14'
-      check-latest: true
-  - run: go run hello.go
-```
-
-## Using stable/oldstable aliases
-
-If `stable` is provided, action will get the latest stable version from the [`go-versions`](https://github.com/actions/go-versions/blob/main/versions-manifest.json) repository manifest. 
-
-If `oldstable` is provided, when current release is 1.19.x, action will resolve version as 1.18.x, where x is the latest patch release.
-
-**Note:** using these aliases will result in same version as using corresponding minor release with `check-latest` input set to `true`
-
-```yaml
-steps:
-  - uses: actions/checkout@v3
-  - uses: actions/setup-go@v3
-    with:
-      go-version: 'stable'
-  - run: go run hello.go
-```
-
-```yaml
-steps:
-  - uses: actions/checkout@v3
-  - uses: actions/setup-go@v3
-    with:
-      go-version: 'oldstable'
-  - run: go run hello.go
-```
-
-## Caching dependency files and build outputs:
-
-The action has a built-in functionality for caching and restoring go modules and build outputs. It uses [actions/cache](https://github.com/actions/cache) under the hood but requires less configuration settings. The `cache` input is optional, and caching is turned off by default.
-
-The action defaults to search for the dependency file - go.sum in the repository root, and uses its hash as a part of the cache key. Use `cache-dependency-path` input for cases when multiple dependency files are used, or they are located in different subdirectories.
-
-**Caching without specifying dependency file path**
-```yaml
-steps:
-  - uses: actions/checkout@v3
-  - uses: actions/setup-go@v3
-    with:
-      go-version: '1.17'
-      check-latest: true
     cache: true
-  - run: go run hello.go
+    
+    # Path to dependency files for caching
+    cache-dependency-path: 'go.sum'
+    
+    # Architecture to install (auto-detected if not specified)
+    architecture: 'x64'
+    
+    # Custom base URL for Go downloads (e.g., for mirrors)
+    go-download-base-url: ''
 ```
+<!-- end usage -->
 
-**Caching in monorepos**
+**Basic:**
-```yaml
-steps:
-  - uses: actions/checkout@v3
-  - uses: actions/setup-go@v3
-    with:
-      go-version: '1.17'
-      check-latest: true
-      cache: true
-      cache-dependency-path: subdir/go.sum
-  - run: go run hello.go
-  ```
-## Getting go version from the go.mod file
-
-The `go-version-file` input accepts a path to a `go.mod` file or a `go.work` file that contains the version of Go to be used by a project. As the `go.mod` file contains only major and minor (e.g. 1.18) tags, the action will search for the latest available patch version sequentially in the runner's directory with the cached tools, in the [version-manifest.json](https://github.com/actions/go-versions/blob/main/versions-manifest.json) file or at the go servers.
-
-If both the `go-version` and the `go-version-file` inputs are provided then the `go-version` input is used.
-> The action will search for the `go.mod` file relative to the repository root
 
 ```yaml
 steps:
-- uses: actions/checkout@v3
+  - uses: actions/checkout@v6
-- uses: actions/setup-go@v3
+  - uses: actions/setup-go@v6
     with:
-    go-version-file: 'path/to/go.mod'
+      go-version: '1.25' # The Go version to download (if necessary) and use.
-- run: go version
-```
-
-## Matrix testing
-
-```yaml
-jobs:
-  build:
-    runs-on: ubuntu-latest
-    strategy:
-      matrix:
-        go: [ '1.14', '1.13' ]
-    name: Go ${{ matrix.go }} sample
-    steps:
-      - uses: actions/checkout@v3
-      - name: Setup go
-        uses: actions/setup-go@v3
-        with:
-          go-version: ${{ matrix.go }}
   - run: go run hello.go
 ```
 
-### Supported version syntax
+**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](https://github.com/npm/node-semver#versions) 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](https://github.com/actions/go-versions/blob/main/versions-manifest.json).
+3. **Direct download** - If that lookup misses or fails, it will fall back to downloading directly from the [official Go distribution site](https://go.dev/dl).
+
+To change the default behavior, please use
+the [check-latest input](docs/advanced-usage.md#check-latest-version).
+
+> **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: `1.15`, `1.16.1`, `1.17.0-rc.2`, `1.16.0-beta.1`
+- Specific versions: `1.25`, `1.24.11`, `1.24.0-rc.1`, `1.23.0-beta.1`
-- SemVer's version range syntax: `^1.13.1`, `>=1.18.0-rc.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 more information about semantic versioning, please refer to [semver](https://github.com/npm/node-semver) documentation.
+For details on Semantic Versioning, see [the semver package documentation](https://github.com/npm/node-semver).
 
-## Using `setup-go` on GHES
+> **Note**: Due to the peculiarities of YAML parsing, it is recommended to wrap the version in single quotation marks:
+>
+> ```yaml
+>   go-version: '1.20'

-`setup-go` comes pre-installed on the appliance with GHES if Actions is enabled. When dynamically downloading Go distributions, `setup-go` downloads distributions from [`actions/go-versions`](https://github.com/actions/go-versions) on github.com (outside of the appliance). These calls to `actions/go-versions` are made via unauthenticated requests, which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting). If more requests are made within the time frame, then you will start to see rate-limit errors during downloading that looks like: `##[error]API rate limit exceeded for...`. After that error the action will try to download versions directly from https://storage.googleapis.com/golang, but it also can have rate limit so it's better to put token.
+For more usage examples, please refer to the section: [Using go-version input](docs/advanced-usage.md#using-the-go-version-input) of the [Advanced usage](docs/advanced-usage.md) guide.
 
-To get a higher rate limit, you can [generate a personal access token on github.com](https://github.com/settings/tokens/new) and pass it as the `token` input for the action:
+## Recommended permissions
+
+When using the `setup-go` action in your GitHub Actions workflow, it is recommended to set the following permissions to ensure proper functionality:
 
 ```yaml
-uses: actions/setup-go@v3
+permissions:
-with:
+  contents: read # access to check out code and install dependencies
-  token: ${{ secrets.GH_DOTCOM_TOKEN }}
-  go-version: 1.18
 ```
 
-If the runner is not able to access github.com, any Go versions requested during a workflow run must come from the runner's tool cache. See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server@3.2/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)" for more information.
+## Caching dependency files and build outputs
 
-# License
+The action includes built-in caching and restoration for Go modules and build outputs. It uses
+[toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under the hood, but requires less configuration.
+The `cache` input is optional, and caching is enabled by default. To disable caching, set `cache: false`.
 
-The scripts and documentation in this project are released under the [MIT License](LICENSE)
+By default, the action looks for `go.mod` in the repository root and uses its hash as part of the cache key. Use the `cache-dependency-path` input when you have multiple dependency files, or when they’re located in different subdirectories. This input supports glob patterns.
 
-# Contributions
+If caching cannot be performed for any reason, the action logs a warning and continues workflow execution.
 
-Contributions are welcome! See [Contributor's Guide](docs/contributors.md)
+For examples of using `cache-dependency-path`, see the [Caching](docs/advanced-usage.md#caching) section of the [Advanced usage](docs/advanced-usage.md) guide.
