…nt64
doc/source/whatsnew/vX.X.X.rstfile if fixing a bug or adding a new feature.Only if dtypes are equal (e.g uint64 vs uint64, uint32 vs uint32...)
%timeit data["uints"].isin([np.uint64(1), np.uint64(2)]) # 17ms (!)
The last line, with older numpy==1.26.4 (last version <2.0), is even worse: ~200ms.
