Every change to Python requires a NEWS entry.

Please, add it using the blurb_it Web app or the blurb command-line tool.

This looks great, thanks!

In addition to my other comments, two other things:

As I believe you are a first-time contributor, you should probably add your name to Misc/ACKS.
Maybe add a very simple test to TestModule, like this:

deftest_utc_alias(self):
self.assertIs(UTC, timezone.utc)

Thanks for your contribution!

I had to move the definition of datetime.UTC to the end so that modifications to datetime.timezone.utc doesn't make it a different object.

…t is an alias

1. Add UTC definition into C implementation as well (just for consistency, there's no particular reason not to simply assign the alias in the Python code later). 2. Move `..versionadded` tag into the right place

Thanks @Kab1r!

Resolves an issue Ken reported running tests in the QA farm, which is due to use of an interface from more-recent-python: python/cpython#91973
