We should add a dedicated page with links to docs of older PyMongo versions that no longer show up in the version picker.

ORIGINAL DESCRIPTION

I am currently working on removing the API documentation version list from https://api.mongodb.com/python/. For PyMongo I was unable to find any other way to navigate to the version list from the API documentation or elsewhere.
 
Could you create a page in the API documentation somewhere that directly links to each version of the docs instead of relying on the api.mongodb.com/python page? Thanks.
