Can you also reflect your changes in composer.json? It looks like php version 5 is not supported anymore and twig v 3 is supported

@mente Not sure what you mean, it should be covered by symfony/twig-bundle v5, not sure if it invalidates twig v2 use.
And PHP is already at ^7.2

edit: Oh, guess it was pretty weird not having twig as a requirement, updated, that's what you mean?
edit: Works in PHP 8, so updated to >=7.2
