DsPartTagColumn has been deprecated.Use AbsTagPartColumnn in cm.abstract.part.partColumn .
As of 16.0, preview image support has been implemented for core Parts and is no longer exclusive to DsParts.
As a result, the global constant dsPreviewColumn has been removed from cm.abstract.dataSymbol as well as the DsPreviewColumn itself.
The core version of this column is in cm/core/calc/init/partPreviewColumn.cm. A renamer has also been added to direct loaded DsPreviewColumn types to the new PartPreviewColumn type.
A new constant of the column (called partPreviewColumn) has been added and is registered in cm/core/init/corePartColumns.cm.
