NumPy 1.21 support tracker

[gmarkall]

List of known items needed to support NumPy 1.21:

• Ufunc method incompatibility with Numpy 1.21 #7175
• numpy 1.21 ufunc reduce segfault #7423

Fixed by the now merged #7483, which includes the C code changes from #7449. Closing.

Potentially stupid question: This issue is closed, but the numpy 1.20 issue (#6182) is still open. What does this mean for numba and support of numpy 1.20? Should we skip numpy 1.20 when using numba or should we pin numpy<1.20?

It's a good question - NumPy 1.20 and 1.21 are supported, but the final bug on the checklist for #6182 is still open and unresolved: #6864 - this is a bug affecting Numba with both NumPy 1.20 and 1.21, so the support for them is equal - but we do need to fix #6864 still.
