	The sql_flush() positional argument sequences is replaced by the boolean keyword-only argument reset_sequences. This ensures that the old function signature can't be used by mistake when upgrading Django. When the new argument is True, the sequences of the truncated tables will reset. Using a single boolean value, rather than a list, allows making a binary yes/no choice as to whether to reset all sequences rather than a working on a completely different set.
