 ### Added
 
+- Updated MAPL_CapGridComp to mark fields going to ExtData to not be checkpointed by components
 - Add debug loggers for start/stop during stages in MAPL_Generic
 - Handling for double precision input when retrieving single precision attributes
 - Enable GCM run test in CircleCI (1-hour, no ExtData)
