I'm getting these deprecation notices about classes that will be removed in 3.0. They aren't listed in the UPGRADE-3.0.md yet.

DEPRECATED - The Symfony\Component\Form\Extension\Core\ChoiceList\SimpleChoiceList class is deprecated since version 2.7 and will be removed in 3.0. Use Symfony\Component\Form\ChoiceList\ArrayChoiceList instead.

It would be great if they were added.
