From the pickle.Pickler docstring:

> The optional *protocol* argument tells the pickler to use the given
> protocol; supported protocols are 0, 1, 2, 3 and 4.  The default
> protocol is 3; a backward-incompatible protocol designed for Python 3.

That's out of date since Python 3.8, where the default protocol is 4 and the highest available is 5. For future-proofing, it may be worth rewording the docstring to refer directly to the DEFAULT_PROTOCOL and HIGHEST_PROTOCOL constants.
