Description: 

The code that deals with extra fields was moved from the field API to the entity API. This means that:

  • hook_field_extra_fields() was renamed to hook_entity_extra_field_info().
  • field_info_extra_fields and Field::fieldInfo()->getBundleExtraFields() were replaced by \Drupal::entityManager()->getExtraFields()
