wheel version 0.38.0 is incompatible with python < 3.7

[smistad]

The line "from __future__ import annotations" was added to the file src/wheel/__init__.py in version 0.38.0.
This makes the wheel package incompatible with python versions < 3.7 as __future__ annotations was not added until python 3.7 (https://peps.python.org/pep-0563/#enabling-the-future-behavior-in-python-3-7).

I think a lot of people are still using version 3.6 of python, including myself, and wheel 0.38.0 broke my build setup with the error message "SyntaxError: future feature annotations is not defined".

First of all, the 0.38.0 release was yanked from PyPI, so it won't be downloaded unless you explicitly specify the version. Second, it was packaged with a specifier that prevents installation on Pythons earlier than 3.7. If your tools are so ancient they will not honor any of these restrictions, I suggest you upgrade.
