Building against np 1.19 does leave a bit of a support gap where someone could have installed from source an older numpy and then pip installed our wheel, but they always have the fall-back of building mpl from source as well.

Any idea when you will release 3.9 wheels? I am hoping to release NetworkX 2.6 in December. We've recently made Matplotlib a default dependency (previously it was optional). We plan to support 3.9 with our 2.6 release. Matplotlib wheels for 3.9 is our last task before NetworkX officially support 3.9.

No rush, just want your rough estimate so I can have a better handle on our release plans.

It would indeed be great to know this so we can plan our releases.
Is there a roadmap somewhere that would indicate when Matplotlib will work with 3.9?

"Soon", definitely before December.

I do want to stress that Matplotlib works with py39, it is the packaging that is not done.

Excellent!

Yes what "works" depends on use case of course. My focus was on something that worked with the vast majority of package consumers (esp. consumers of packages for which Matplotlib is just a dependency), for whom "works" means pip install works.

It seems like this should be ready because all tests pass - looking forward to finally moving to Python 3.9! Big thanks for providing this great package 👍!

I don't know if the tests passing means anything. @QuLogic any hints for how we can tell if this is working?

These would only run on the main branches, not PRs; here is a (somewhat older) build on master and one on v3.3.x.
