Happy New Year ;)

There is a "2016" in cpython/PC/python_ver_rc.h, it could be changed to 2021.

Last year, @benjaminp did the commit: commit 946b29e.

[vstinner]

LGTM.

You modified the same files than last year commit, but you also updated PC/python_ver_rc.h which is a good thing.

This change should not be backported to 3.6 and 3.7, it's not a security fix: https://devguide.python.org/#status-of-python-branches

Could we stop making these constant changes to the license texts just for a new year? These really do not matter much. Constant changes (as in at least once per year) in the license texts make the downstream identification more complex and brings zero benefits IMHO.
