 # What's new
 
-- Updated to the node16 runtime by default
+- Improved performance
-  - This requires a minimum [Actions Runner](https://github.com/actions/runner/releases/tag/v2.285.0) version of v2.285.0 to run, which is by default available in GHES 3.4 or later.
+  - Fetches only a single commit by default
+- Script authenticated git commands
+  - Auth token persisted in the local git config
+- Supports SSH
+- Creates a local branch
+  - No longer detached HEAD when checking out a branch
+- Improved layout
+  - The input `path` is always relative to $GITHUB_WORKSPACE
+  - Aligns better with container actions, where $GITHUB_WORKSPACE gets mapped in
+- Fallback to REST API download
+  - When Git 2.18 or higher is not in the PATH, the REST API will be used to download the files
+  - When using a job container, the container's PATH is used
+
+Refer [here](https://github.com/actions/checkout/blob/v1/README.md) for previous versions.
