• Default install of tortoise-orm now installs with no C-dependencies, if you want to use the C accelerators, please do a pip install tortoise-orm[accel] instead.
• Added <instance>.clone() method that will create a cloned instance in memory. To persist it you still need to call .save()
• .clone() will raise a ParamsError if tortoise can't generate a primary key. In that case do a .clone(pk=<newval>)
• If manually setting the primary key value to None and the primary key can be automatically generated, this will create a new record. We however still recommend the .clone() method instead.
• .save() can be forced to do a create by setting force_create=True
• .save() can be forced to do an update by setting force_update=True
• Setting update_fields for a .save() operation will strongly prefer to do an update if possible
