Changes between Initial Version and Version 1 of Ticket #27340, comment 4

-              initial
+              v1
 With the proposed change we'd be able to avoid doing two database queries for every Model.save by doing this:
+ {{{
 @signals.pre_init.connect
 def _track_changes(instance, args, kwargs, **kwargs):
     instance._original_args = args, kwargs
+}}}
 There's no other way as far as I can find, as we don't want to monkeypatch Model, and in any case it's very strange that the pre_init signal omits the instance being created.
