- Doctrine DBAL 3 → 4 : suppression use_savepoints, replace prepare/executeQuery
- Doctrine ORM 2.x → 3.x : ClassMetadataInfo → ClassMetadata, setParameters → setParameter
- Doctrine Bundle 2.x → 3.x, Fixtures Bundle 3.x → 4.x
- zenstruck/foundry 1.x → 2.x : ModelFactory → PersistentObjectFactory, getDefaults → defaults
- phpmd/phpmd 2.x → 3.x-dev (seule version supportant Symfony 8)
- phparkitect 0.3 → 0.8 : NotDependsOnTheseNamespaces prend un array
- symfony/mercure-bundle 0.3 → 0.4, symfony/monolog-bundle 3 → 4
- Suppression de runtime/frankenphp-symfony (intégré nativement dans symfony/runtime 8)
