Several new warnings need to be addressed:

Observation examples (may not be a full list):

All observations should have a subject

All observations should have a performer{}

All observations should have an effectiveDateTime or an effectivePeriod{}

Several best practice warnings: (may not be a full list)

Rule dom-6: 'A resource should have narrative for robust management' Failed (Best Practice Recommendation)

UCUM Codes that contain human readable annotations like {reads} can be misleading. Best Practice is not to use annotations in the UCUM code, and rather to make sure that Quantity.unit is correctly human readable

This should also include reviewing the 'ignoreWarnings.txt' for warning that no longer apply and can be removed.
