A short while ago, I released mdut, and even wrote about it.
Amidst all the excitement of a new shiny, I somehow managed to use the wrong CalVer implementation—YYYY.minor.micro instead of my preferred YY.minor.micro.
Since I’m reasonably sure I’m literally the only user, I’ve yanked deleted the five current versions from PyPI and releasing a new version, which is all documented on the package's history page.
If you somehow have any of the 2022.x.y versions, please uninstall them before reinstalling 22.x.y.
Oopsies.
