 ## Compatibility
 
 - `github-action@v6` is the current recommended version, uses `node20` and is compatible with Cypress `10` and above.
+- `github-action@v6.7.9` is the minimum version required to use GitHub Actions caching services. The legacy caching service used by lower versions of the action is no longer available.
 - `github-action` versions `v1` to `v5` are unsupported: they rely on Node.js `12` and `16` in End-of-life status.
