@pllim It's still running! but RTD is still bringing up the warning.

The validCap attribute was deprecated in Matplotlib 3.4 and will be removed two minor releases later.
  return getattr(obj, attr, *defargs)

I don't know what the difference is between #11118 and this, but it looks like #11464 might still be necessary. 😰.

As long as RTD doesn't fail, I don't really care if the warnings are there or not anymore. I feel like we have wasted too much time on this... 😅

FWIW, I have been playing with different directives from Sphinx autodoc and our own sphinx-automodapi but these warnings are very hard to get rid of. I have a feeling that sphinx_automodapi/autodoc_enhancements.py#L71 happens before all the skipping stuff.

@pllim @eteq , RTD compiles 🥳

Manual backport for this is #11468 and hopefully we won't need anymore backports given this is a temporary solution.

@pllim, is this something I should do? how does one PR a backport?

@nstarman , don't worry about the backports. The release managers take care of that and we have helper scripts. 😄 Thanks again for your fix!

I think we need to backport this. I see the same warnings on RTD build for LTS, causing it to fail.
