Yes. It appears the command line option has changed in the latest version off the tool that I downloaded yesterday. It was a surprise to me too because the change seems arbitrary and unnecessarily breaks compatibility. And I guess whoever made the change also didn't update the documentation.
This is what you get when you run the latest version of the tool with the --help option. Note the change in the option.
ovr-platform-util.exe --help upload-rift-build
Parameters
<snip>
--windowsx-min-version, --windowsx_min_version, -w Minimum required Windows version
[choices: "10", "7SP1", "8.1"] [default: "7SP1"]
I also tried using the -w option, since that has not changed, and get the same result.
