[New-bugs-announce] [issue46208] os.path.normpath change between 3.11.0a2 and 3.11.0a3+

[Hugo van Kemenade]

New submission from Hugo van Kemenade <hugovk+python at gmail.com>:

The behaviour of os.path.normpath appears to have changed between Python 3.10/Python 3.11.0a2 and 3.11.0a3+.

I don't see anything mentioned in https://docs.python.org/3.11/whatsnew/3.11.html

Is this intentional?
