Since Python 3.9.5, `urllib.parse.urljoin` now strips newlines from the destination URL.

I think this should be at least mentioned in the `/Misc/NEWS.d`.

Python 3.8.10:

>>> urllib.parse.urljoin('http://a.ru', '\nsome/location')
'http://a.ru/\nsome/location'


Python 3.9.5:

>>> urllib.parse.urljoin('http://a.ru', '\nsome/location')
'http://a.ru/some/location'


We had an extra check for newlines in our Python codebase and our test started to fail.

Sorry, I found the commit that mentions this https://github.com/python/cpython/commit/0593ae84af9e0e8332644e7ed13d7fd8306c4e1a

It's not live on Python.org though.
