+# 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.
