On the older version docs pages such as this one: https://circuitpython.readthedocs.io/en/4.x/shared-bindings/displayio/Group.html

There is a warning at the top and center but I find it somewhat easy to overlook when I arrive on a docs page from a google search or other link.

The two ideas for improvement I had were to make the warning a bolder color and/or make it scroll with the page so it's always visible.
