Important information about breaking changes and backward incompabilities

4.* to 5.0

`EndlessContainerAwareCommand` removed

Since ContainerAwareInterface has been deprecated in Symfony 6.4, programmers are encouraged to use dependency injection instead in the constructor.

Therefore, it makes no sense to keep EndlessContainerAwareCommand. If you need to call EntityManager::clear() on your doctrine instance inside EndlessCommand::finishIteration(), you have to handle this in your code now.

If you need to access any service, inject it in the constructor of your derived class.

Other behaviour changes

Shutting down during startup will NOT run any iteration of the loop, previous versions did always at least run one iteration.
Support for using setCode to provide an implementation is removed.
