 - QgsCRSCache was removed. QgsCoordinateReferenceSystem now internally uses a cache for CRS creation,
 so there is no longer a need for the separate cache class. Code which previously called QgsCRSCache::updateCRSCache()
 should now call QgsCoordinateReferenceSystem::invalidateCache() and QgsCoordinateTransformCache::instance()->invalidateCrs( authid ).
+- QgsDataDefined was removed. Use the QgsProperty framework instead.
 - QgsDataDefinedButton was removed. Use QgsPropertyOverrideButton instead.
 - QgsFileNameWidgetWrapper was removed. Use QgsExternalResourceWidgetWrapper instead.
 - QgsFormAnnotationItem. Use QgsFormAnnotation instead.
