+This action sets up a go environment for use in actions by:

- Optionally downloading and caching a version of Go by version and adding it to the PATH
- Optionally caching Go modules and build outputs
- Registering problem matchers for error output
+- Optionally downloading and caching a version of Go by version and adding to `PATH`.
+- Registering problem matchers for error output.

+# V5

-## What's new in V7
+The V5 edition of the action offers:

-The V7 edition of the action includes:
- Migrated action internals to ESM for compatibility with latest `@actions/*` packages. 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](https://github.com/actions/runner/releases/tag/v2.327.1)
-
- **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.
+- Upgraded Node.js runtime from node16 to node20

 See full release notes on the [releases page](https://github.com/actions/setup-go/releases).

-## Usage
+# V4

-See [action.yml](action.yml).
+The V4 edition of the action offers:

-<!-- start usage -->
-```yaml
- uses: actions/setup-go@v6
-  with:
-    # Version or version range of Go to use
-    go-version: '1.23'
-    
-    # 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: 'go.mod'
-    
-    # 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: '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 -->
+ - Enabled caching by default

-**Basic:**
+The action will try to enable caching unless the `cache` input is explicitly set to false.
+
+Please see "[Caching dependency files and build outputs](https://github.com/actions/setup-go#caching-dependency-files-and-build-outputs)" for more information.
+
+# V3
+
+The V3 edition of the action offers:
+
+- Adds `GOBIN` to the `PATH`
+- Proxy support
+- Check latest version

+
+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).
+
+**Note:** The `setup-go` action uses executable binaries which are built by Golang side. The action does not build
+golang from source code.
+
+Matching by [semver spec](https://github.com/npm/node-semver):

 ```yaml
 steps:
-  - uses: actions/checkout@v6
+  - uses: actions/checkout@v5
  - uses: actions/setup-go@v6
    with:
-      go-version: '1.25' # The Go version to download (if necessary) and use.
-  - run: go run hello.go
+      go-version: '^1.13.1' # The Go version to download (if necessary) and use.
+  - run: go version
 ```

-**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: `1.25`, `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](https://github.com/npm/node-semver).

+Matching an unstable pre-release:
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: '1.18.0-rc.1' # The Go version to download (if necessary) and use.

+```
+
+```yaml
+steps:

+  - uses: actions/setup-go@v6
+    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@v5
+  - uses: actions/setup-go@v6
+    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@v5
+  - uses: actions/setup-go@v6
+    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@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: 'stable'
+  - run: go run hello.go
+```
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    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 [toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under the hood but requires less configuration settings.
+The `cache` input is optional, and caching is turned on 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. The input supports glob patterns.
+
+If some problem that prevents success caching happens then the action issues the warning in the log and continues the execution of the pipeline.
+
+**Caching in monorepos**
+
+```yaml
+steps:
+  - uses: actions/checkout@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version: '1.17'
+      check-latest: true
+      cache-dependency-path: |
+             subdir/go.sum
+             tools/go.sum
+    # cache-dependency-path: "**/*.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.
+
+The `go` directive in `go.mod` can specify a patch version or omit it altogether (e.g., `go 1.22.0` or `go 1.22`).  
+If a patch version is specified, that specific patch version will be used.  
+If no patch version is specified, it will search for the latest available patch version in the cache,
+[versions-manifest.json](https://github.com/actions/go-versions/blob/main/versions-manifest.json), and the
+[official Go language website](https://golang.org/dl/?mode=json&include=all), in that order.
+
+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@v5
+  - uses: actions/setup-go@v6
+    with:
+      go-version-file: 'path/to/go.mod'
+  - 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@v5
+      - name: Setup go
+        uses: actions/setup-go@v6
+        with:
+          go-version: ${{ matrix.go }}
+      - run: go run hello.go
+```
+
+### 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`
+- SemVer's version range syntax: `^1.13.1`, `>=1.18.0-rc.1`
+
+For more information about semantic versioning, please refer to [semver](https://github.com/npm/node-semver)
+documentation.
+
+## Using `setup-go` on GHES
+
+`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 the action leverages the `raw API` to retrieve the version-manifest. This approach does not impose a rate limit and hence facilitates unrestricted consumption. This is particularly beneficial for GHES runners, which often share the same IP, to avoid the quick exhaustion of the unauthenticated rate limit.
+If that fails as well the action will try to download versions directly from https://storage.googleapis.com/golang.
+
+If that fails as well you can get a higher rate limit with [generating a personal access token on github.com](https://github.com/settings/tokens/new) and passing it as the `token` input to the action:
+
+```yaml
+uses: actions/setup-go@v6
+with:
+  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)"
