@jbrockmendel - not sure we can still change the 1.12.0 documentation, though if it is possible, I'd be all for it. In any case, only __array_ufunc__ actually exists, and the 1.13.0 documentation has more information [1]. If you want a more complete/complicated example of its use, see astropy/astropy#2583 for work I did for astropy's Quantity class.

Thanks, I'd been using an older version of astropy.units as a template for poking at __array_wrap__, hadn't seen the version in 2583. Using __array_ufunc__ tentatively seems to solve my use case quite cleanly.

I had seen the neps/ufunc-overrides.html page, but did not see anything saying "this is now implemented". Maybe that can go on the wish-list along with updating the 1.12.0 docs.

Yes, someone elsewhere mentioned that the release notes seem to be missing! (It was in the e-mail @charris sent, but someone not elsewhere)

I don't think we still want to amend the 1.12.0 docs at this point, however a There is a newer version banner for all new doc builds would be nice to have.

https://docs.scipy.org/doc/numpy/neps/index.html has two sections, Implemented NEPS and Other NEPS. https://docs.scipy.org/doc/numpy/neps/ufunc-overrides.html is under the former, and is up to date.
