Pandas version checks
Location of the documentation
Any page
Documentation problem
When I try to see the docs for a different pandas version and chose any version in the top right version select widget I get redirected to https://pandas.pydata.org/docs/dev/undefined and get 404 error
Might have something to do with the error I see in the browser console:

Suggested fix for documentation
Fix the version select widget so it redirects to the documentation for the chosen version
