Do you let your diesel idle, before killing it

[Bluegill]

After driving a while or even after just driving to the grocery store, Do you let your diesel idle a while before you shut it off? I have heard different opinions. The diesels of yester-year needed to idle a while but today's deisel doesnt.
I'm going to try to find something in my owners manual.
