Manual Upgrades

There are some upgrades the Laravel 13.x Shift can not perform automatically. When Shift detects these it adds a detailed comment to the Pull Request to guide any additional steps you may need to do manually.

While Shift attempts to detect and automate the updates for popular packages, you may need to update some of your dependencies manually. Always review the changelog for your dependencies for any additional changes.
