I did executed "make htmldocs" on sphinx-build 1.8.5 and sphinx_2.4.4, which throws the warning but on executing the same on sphinx_7.1.0 - one 
can't see the warning

I skip the patch.

Yeah, your are right. 
On executing the make htmldocs, it clearly throws the warning
"WARNING: support for Sphinx < 2.4 will be removed soon"

My ignorance.

Thanks for pointing it.
