Improvements

  • Load the mapper database lazily instead of at GUI startup, avoiding a redundant database read when opening the GUI or a project.
  • Tint UI icons to the palette for improved dark theme legibility.
  • Show image/point viewer metadata when the source images are missing on disk.
  • Fail the Caspar build early with a clear error on CUDA architectures below 7.0.

Bug Fixes

  • Fix feature matching slowdown (~4-6x) caused by a process-global OpenMP critical section in RANSAC/LORANSAC.
  • Fix rescaling of already-undistorted images when max_image_size is provided.
  • Fix missing SVG icons in the distributed Windows binaries.
  • Fix Caspar CUDA build with MSVC forced includes.
  • Fix glog color support version detection.
  • Fix typos in a user-facing help string and the FAQ.

Breaking Changes

  • Renamed the misspelled pycolmap enum GPSTransfromEllipsoid to GPSTransformEllipsoid. The old name has been removed without a backwards-compatible alias; update any references accordingly.
