-geotiff,2026-05-11,1632,HIGH,1;5,extract_geo_info dropped user-defined CRS WKT: GeoKey *CSTypeGeoKey=32767 files emitted attrs[crs_name] only (no crs/crs_wkt) so to_geotiff silently lost the projection on read->write. Fixed by promoting WKT-looking citation to crs_wkt across all four read backends (#1632).
+geotiff,2026-05-11,1640,HIGH,1;2;4,"open_geotiff(overview_level>=1) silently dropped CRS, transform attr, and georeferenced y/x coords because GDAL-style COGs (including to_geotiff output) write GeoKeys only on the level-0 IFD. Fixed by inheriting and rescaling georef from the level-0 IFD across all four read backends (#1640)."
 reproject,2026-05-10,1572;1573,HIGH,1;3;4,geoid_height_raster dropped input attrs and used dims[-2:] for 3D inputs (#1572). reproject/merge ignored nodatavals (rasterio convention) when rioxarray absent (#1573). Fixed in same branch.
