We've been hard at work behind the scenes to provide support for all our libraries so that upgrading to PHP 8 with Laravel is easy. First, make sure you're at the latest version of Laravel 6, 7 or 8 to get PHP 8 support. Then make sure you're on the very latest version of any first-party package from Laravel like Passport, Cashier, Dusk, etc. There are also a couple of commonly used dependencies you'll need to update in your composer.json file: Finally, run composer update to update other packages. Make sure to test your application before updating production.
