The Tkinter module, in a freshly built copy of Python 3.9 built by Brew, using the latest Xcode 12.3 command line tools, crashes on Big Sur 11.1 beta. It emits the following error:

macOS 11 or later required !

I believe I recently read on macOS developer documentation, there is a special behavior in the system version reporting now, possibly only taking effect in 11.1 and newer. Basically, if you query the major version first, you'll get 11 or higher. If you query the minor version first, it will switch on compatibility mode and start reporting either 10.15 or 10.16, I'm not terribly sure which, but it does lie and say it's running version 10.
