%description
MRIcron is a cross-platform NIfTI format image viewer. It allows viewing
multiple layers of images, generating volume renderings, and drawing volumes
of interest (VOI). This is the native compiled version built with Lazarus
and Qt5.

%changelog
* Tue Sep 29 2026 Morgan Hough <morgan.hough@gmail.com> - 1.2.20250101-4
- Ship AppStream metadata (mricron.metainfo.xml). A desktop entry makes an application
  launchable; a metainfo file makes it DISCOVERABLE, because GNOME Software
  and KDE Discover list only applications that ship one. Twenty of the
  twenty-six applications in this repo had a desktop entry and no metainfo,
  so they were invisible in the software centre even once installed.
  Validated at build time with appstream-util validate-relax --nonet, in
  %install rather than %check, so a malformed file fails the build.
- Added Requires: hicolor-icon-theme, which the icons need.

* Tue Sep 29 2026 Morgan Hough <morgan.hough@gmail.com> - 1.2.20250101-3
- Exec takes %%F so the entry can open the file it is given, and MimeType
  is declared for NIfTI and DICOM; without the declaration any default
  pointing here is silently ignored by the desktop.
- Deliberately NOT claiming *.hdr/*.img for Analyze: f3d owns *.hdr as
  Radiance HDR and *.img collides with raw disk images.

* Sun Jan 04 2026 Morgan Hough <morgan.hough@gmail.com> - 1.2.20250101-2
- Fix permissions on templates and LUTs
- Fix line endings (dos2unix) for docs and config files
- Use relative symlink for dcm2niix to satisfy rpmlint

* Sun Jan 04 2026 Morgan Hough <morgan.hough@gmail.com> - 1.2.20250101-1
- Initial RPM release built with Lazarus and Qt5
