w.r.t. https://my.thomsonreuters.com/MTRFDNDetailNotification?dnid=DN088704
does it mean that in future the RDMFieldDictionary will change all UINT32 to UNIT64
Here is the list of fields that will be changed to 64 bit.

The DN said the change was to standardize types in the RDMFieldDictionary. So I believe all future fields will be 64 bit too.
