- Caching is now automatically enabled for npm projects when either the `devEngines.packageManager` field or the top-level `packageManager` field in `package.json` is set to `npm`. For other package managers, such as Yarn and pnpm, caching is disabled by default and must be configured manually using the `cache` input.

- Enabled caching by default with package manager detection if no cache input is provided.
-  > For workflows with elevated privileges or access to sensitive information, we recommend disabling automatic caching by setting `package-manager-cache: false` when caching is not needed for secure operation.
-
- Upgraded action from node20 to node24.

 The action will first check the local cache for a semver match. If unable to find a specific version in the cache, the action will attempt to download a version of Node.js.

 The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under the hood for caching global packages data but requires less configuration settings. Supported package managers are `npm`, `yarn`, `pnpm` (v6.10+). The `cache` input is optional.

+Caching is turned on by default when a `packageManager` field is detected in the `package.json` file. The `package-manager-cache` input provides control over this automatic caching behavior. By default, `package-manager-cache` is set to `true`, which enables caching when a valid package manager field is detected in the `package.json` file. To disable this automatic caching, set the `package-manager-cache` input to `false`.

+```yaml
+steps:
+- uses: actions/checkout@v4

+  with:
+    package-manager-cache: false
+- run: npm ci
+```
+> If no valid `packageManager` field is detected in the `package.json` file, caching will remain disabled unless explicitly configured.
+
 The action defaults to search for the dependency file (`package-lock.json`, `npm-shrinkwrap.json` or `yarn.lock`) in the repository root, and uses its hash as a part of the cache key. Use `cache-dependency-path` for cases when multiple dependency files are used, or they are located in different subdirectories.

 ## Caching packages data
 The action follows [actions/cache](https://github.com/actions/cache/blob/main/examples.md#node---npm) guidelines, and caches global cache on the machine instead of `node_modules`, so cache can be reused between different Node.js versions.

 **Caching yarn dependencies:**
-Yarn caching handles both Yarn Classic (v1) and Yarn Berry (v2, v3, v4+).
-
+Yarn caching handles both yarn versions: 1 or 2.
