The serializer context controls the serialization and deserialization of
resources. This context is passed to all normalizers and can be used for example
to set the date/time format, how to represent empty objects and arrays, etc.

In Symfony you can define that context in multiple ways: as a PHP array passed to
serialize() and deserialize() methods, as a framework.serializer.default_context
global configuration option and via the #[Context] attribute on class properties.

In Symfony 6.4 we’re introducing a new way of setting the serializer context:
using the #[Context] attribute on the class itself:

The class-based #[Context] attribute is applied to all properties of the class,
which can override that configuration with their own #[Context] attributes.
This new feature will improve DX (developer experience) when working with the
Serializer component and will make you more productive by avoiding repetition.
