+UPGRADE FROM 7.3 to 7.4
+=======================
+
+Symfony 7.4 is a minor release. According to the Symfony release process, there should be no significant
+backward compatibility breaks. Minor backward compatibility breaks are prefixed in this document with
+`[BC BREAK]`, make sure your code is compatible with these entries before upgrading.
+Read more about this in the [Symfony documentation](https://symfony.com/doc/7.4/setup/upgrade_minor.html).
+
+If you're upgrading from a version below 7.3, follow the [7.3 upgrade guide](UPGRADE-7.3.md) first.
