wouterj, 
Almost missed the day Symfony 7 was released!
Check out the huge effort the past 2 years by the Symfony community at https://symfony.com/7
Also, we've spent more time on the UPGRADE guide. If you're removing deprecations from your 6.4 app, make sure to take a look at https://github.com/symfony/symfony/blob/7.0/UPGRADE-7.0.md
