For example,
in the old part editor, I can selected the component'SN65HVD232'in the schematic diagram,then right-clicked edit part, and selected Package properties under options. The name 'SN65HVD232_0' in it can berenamed to any other one.
But , in the new version of the Part Editor, the Package properties option under options is not optional gray. Although there are Package properties settings on the right side of the main window, the name SN65HVD232_0 is also not set and can not be renamed.
