Summary

  • Removes 32-bit Windows and x86-64 macOS from CI and the wheel-builder.
  • macOS wheels are now built arm64-only with MACOSX_DEPLOYMENT_TARGET=11.0 and _PYTHON_HOST_PLATFORM=macosx-11.0-arm64 (instead of universal2).
  • Adds Python 3.9 to the macOS CI matrix as the minimum testable Python on arm64 macOS (3.8 had no arm64 binary).
  • Removes the obsolete PROCESSOR_ARCHITEW6432 runtime warning for 32-bit Python on 64-bit Windows, along with its now-unused imports.
  • Updates CHANGELOG.rst and docs/installation.rst.

Closes #13519
Closes #13520

Test plan

  • CI passes on the remaining macos-15 (arm64) and win64 runners.
  • Wheel builder produces only arm64 macOS wheels and only win_amd64 Windows wheels.

This probably needs to come after dropping 3.8
