Pickle protocol version 4.0 was originally defined back in PEP 3154 and shipped as part of Python 3.4 back in 2011. Yet it's still not the default.
Because we want pickles produced with the default to be readable by earlier Python 3 versions. (the same reason protocol 0 stayed the default throughout the Python 2 lifetime) Regards Antoine.
