Important: #87427 - ClassSchema constants marked as private 

See forge#87427

Description 

The constants

  • ClassSchema::MODELTYPE_ENTITY and
  • ClassSchema::MODELTYPE_VALUEOBJECT

have been marked as private, as they are used in \TYPO3\CMS\Extbase\Reflection\ClassSchema only.

Since this class is marked as internal explicitly, nobody should be affected by this change.
