I'll also summarize again: 1. The default build settings increase the hardware requirements to x86-64-v2, dropping support for pre-2009 hardware and a few specific Intel Atom CPUs produced in the 2009-2013 timeframe. 2. This will affect <0.22% of machines based on the best data we have 3. A previous such bump to SSE3 caused no problems. We set the threshold for allowing to drop support at <0.5% at that time 4. If anyone with ancient hardware is affected, they can still build NumPy from source with the `-Ddisable-optimizations=true` flag, that will still work and use the scalar implementations. Or pin to <2.4.0 if they want to use wheels from PyPI. Cheers, Ralf
