Hi All, This is to propose dropping Python 3.7 for NumPy 1.22. Doing so will allow merging the array API standard <https://github.com/numpy/numpy/pull/18585> (keyword only arguments), simplify removing import time compiles <https://github.com/numpy/numpy/pull/19638>, allow making 64 bit pickles the default, and bring annotations closer to current. NEP 29 <https://numpy.org/neps/nep-0029-deprecation_policy.html> suggests Dec 26, 2021 for the drop date, which is close to the likely 1.22 release date, but given the advantages of dropping 3.7 I think there are good reasons to cheat by a week or two if needed. Downstream projects releasing after 1.22 will probably want to drop Python 3.7 anyway, as they will be past the deadline. Thoughts? Chuck
