UPGRADE FROM 6.4 to 7.0

Symfony 6.4 and Symfony 7.0 are released simultaneously at the end of November 2023. According to the Symfony release process, both versions have the same features, but Symfony 7.0 doesn't include any deprecated features. To upgrade, make sure to resolve all deprecation notices. Read more about this in the Symfony documentation.

Symfony 7.0 introduced many native return and property types. Read the announcement blogpost on how to quickly make your code compatible.
