    🛠 Fixes :wrench:
    • 🛠 Fixed a regression where older tilesets without a top-level geometricError would fail to load. #9618
    • 🛠 Fixed an issue in WebMapTileServiceImageryProvider where using URL subdomains caused query parameters to be dropped from requests. #9606
    • 🛠 Fixed an issue in ScreenSpaceCameraController.tilt3DOnTerrain that caused unexpected camera behavior when tilting terrain diagonally along the screen. #9562
    • 🛠 Fixed error handling in GlobeSurfaceTile to print terrain tile request errors to console. #9570
    • 🛠 Fixed broken image URL in the KML Sandcastle. #9579
    • 🛠 Fixed an error where the positionToEyeEC and tangentToEyeMatrix properties for custom materials were not set in GlobeFS. #9597
    • 🛠 Fixed misleading documentation in Matrix4.inverse and Matrix4.inverseTransformation that used "affine transformation" instead of "rotation and translation" specifically. #9608
    • 🛠 Fixed a regression where external images in glTF models were not being loaded with preferImageBitmap, which caused them to decode on the main thread and cause frame rate stuttering. #9627
    • 🛠 Fixed misleading "else" case condition for color and show in Cesium3DTileStyle. A default color value is used if no color conditions are given. The default value for show, true, is used if no show conditions are given. #9633
    • 🛠 Fixed a crash that occurred after disabling and re-enabling a post-processing stage. This also prevents the screen from randomly flashing when enabling stages for the first time. #9649
    Deprecated :hourglass_flowing_sand:
    • 🚚 Scene.terrainExaggeration and options.terrainExaggeration for CesiumWidget, Viewer, and Scene have been deprecated and will be removed in CesiumJS 1.85. They will be replaced with Globe.terrainExaggeration.
    • 👌 Support for Internet Explorer has been deprecated and will end in CesiumJS 1.84.
