%changelog
* Tue Oct 06 2026 Morgan Hough <morgan.hough@gmail.com> - 5.3.1-7
- Pin the ITK layout state: Requires: itk(abi) = %%{itk_abi}, from InsightToolkit5-devel's macros.itk,
  plus a %%build guard. ITK -23 flipped ITK_LEGACY_REMOVE back off, which changes class layouts at
  unchanged sonames; this package was built against -10..-21 (legacy removed) and the itk_ver floor let it
  install over -23, giving silent wrong results or crashes. Rebuild against ITK >= 5.4.7-24.

* Sat Sep 19 2026 Morgan Hough <morgan.hough@gmail.com> - 5.3.1-6
- Rebuild against InsightToolkit5 5.4.7-8, which unbundles Eigen3, VXL and
  double-conversion. No source or spec change; the Release bump is what makes
  the rebuild reach anyone. COPR adds a sibling at an already-published NVR
  rather than replacing it, and dnf then serves the older copy -- so a rebuild
  at the same NVR would leave this package linked against the bundled ITK while
  appearing to succeed.
- Validated against -8 in mhough/neurofedora-itk5-test before this bump.
* Mon May 18 2026 Morgan Hough <morgan.hough@gmail.com> - 5.3.1-4
- Rebuild against InsightToolkit5 5.4.6 (GDCM CVE-2026-3650, F44 target)
- Bump BuildRequires: InsightToolkit5-devel >= 5.4.6

* Thu Apr 23 2026 Morgan Hough <morgan.hough@gmail.com> - 5.3.1-1
- Update to 5.3.1

* Wed Feb 25 2026 Morgan Hough <morgan.hough@gmail.com> - 5.3.0-2
- Make libminc-devel BuildRequires conditional on Fedora (not available on EPEL 9;
  elastix gets MINC support transitively through ITK which is also built without MINC on EPEL)
- Remove git-core BuildRequires (not needed in network-isolated mock/COPR builds)

* Mon Feb 09 2026 Morgan Hough <morgan.hough@gmail.com> - 5.3.0-1
- Initial package for elastix 5.3.0 built against InsightToolkit 5.4
