* Mon May 25 2026 Morgan Hough <morgan.hough@gmail.com> - 1.12.1-1
- Initial COPR build (mhough/neurofedora), adapted from Fedora f41's
  python-dipy.spec (last live before retirement for orphan). Bumped
  from 1.11.0 → 1.12.1, switched to mesonpy build-system (was setuptools
  in 1.11), explicit Release/changelog instead of autorelease/autochangelog
  to match the COPR's house style. Tests disabled in first build.
