-# Checkout V5
+# Checkout v7
+
+## What's new
+
+- Safer fork pull request handling: checkout now refuses to check out fork pull request code by default when the workflow is triggered by `pull_request_target` or `workflow_run`. These triggers run with the base repository's `GITHUB_TOKEN`, secrets, and runner access, where executing a fork's code commonly leads to "pwn request" vulnerabilities.
+  - To opt in after [reviewing the risks](https://gh.io/securely-using-pull_request_target), set the new `allow-unsafe-pr-checkout: true` input.
+- Migrated `actions/checkout` to ESM to support new versions of the `@actions/*` packages.
+- Updated direct and transitive dependencies, including security fixes for known vulnerabilities.
+
+# Checkout v6
+
+## What's new
+
+- Improved credential security: `persist-credentials` now stores credentials in a separate file under `$RUNNER_TEMP` instead of directly in `.git/config`
+- No workflow changes required — `git fetch`, `git push`, etc. continue to work automatically
+- Running authenticated git commands from a [Docker container action](https://docs.github.com/actions/sharing-automations/creating-actions/creating-a-docker-container-action) requires Actions Runner [v2.329.0](https://github.com/actions/runner/releases/tag/v2.329.0) or later
+
+# Checkout v5
 
 ## What's new
 
 - Updated to the node24 runtime
   - This requires a minimum Actions Runner version of [v2.327.1](https://github.com/actions/runner/releases/tag/v2.327.1) to run.
