What's new in 3.11 doesn’t mention enum improvements

Documentation

There's a number of improvements (e.g. StrEnum) in module enum in version 3.11.0b4 (see https://docs.python.org/3.11/library/enum.html#module-contents).
However, module enum isn’t mentioned in 3.11's What's new documentation https://docs.python.org/3.11/whatsnew/3.11.html#improved-modules.
I suggest adding there to announce. Now I only stumbled upon these new enum features by python/mypy#12841 of @AlexWaygood

It looks like @ethanfurman added this in #95455 and its there now, so closing this.
