[bug#67813] [PATCH 00/12] Update python-pandas to version 2.1.1.

[Ricardo Wurmus]

Good work!

I only just noticed this patch set.  I started work on the
wip-python-science branch, which includes an upgrade to Pandas 1.5.

I think it’s worth keeping Pandas 1.x around, which is still used by
many packages.

Your changes to matplotlib look good; I had updated to 3.8.2 already,
but the changes to the test flags look very useful.

I’ll try to port your patch set to wip-python-science.
