For performance reasons,
django-simple-history always creates an
Model.save() is called regardless of data having actually changed.
If you find yourself with a lot of history duplicates you can schedule the
$ python manage.py clean_duplicate_history --auto

--auto to clean up duplicates for every model
HistoricalRecords or enumerate specific models as args.
There is also
-m/--minutes to specify how many minutes to go
back in history while searching (default checks whole history),
so you can schedule, for instance, an hourly cronjob such as
$ python manage.py clean_duplicate_history -m 60 --auto
