Cesium Releases in January 2025

CesiumJS 1.125 Release

CesiumJS 1.125 is now available. Highlights of the release include:

• Expanded the integration with the iTwin Platform to load GeoJSON and KML data from the Reality Management API. Use ITwinData.createDataSourceForRealityDataId(iTwinId, realityDataId) to load data as the corresponding Data Source. #12344
• Added environmentMapOptions to ModelGraphics. For performance reasons, the environment map will not update if the entity position changes by default. If environment map updates based on entity position are desired, ensure to provide an appropriate environmentMapOptions.maximumPositionEpsilon value. #12358
• Reduced memory usage and performance bottlenecks when using environment maps with models. #12356
• Fixed JulianDate to always generate valid ISO strings for fractional milliseconds. #12345
• Fixed intermittent z-fighting issue. #12337

Cesium for Unity 1.14.1 Release

Cesium for Unity v1.14.1 is now available. This is the last release of Cesium for Unity that will support Unity 2021 LTS (2021.3). Future versions will require Unity 2022 LTS (2022.3) or Unity 6.

Highlights of this release include:

• Fixed a bug that could cause a crash on AppDomain reloads.
• Fixed a bug that could cause a crash or incorrect textures when multiple Cesium3DTileset tiles referenced the same image by URL.
• Fixed a bug that could cause incorrect colors in a model that did have vertex colors but did not have normals.
• Fixed a bug that could cause a hang when attempting to load a model with UINT16 indices where generating flat normals required more than 2^16 vertices.
• Fixed a bug in the Abseil vcpkg overlay port that could cause linker errors on some systems.

This release updates cesium-native from v0.42.0 to v0.43.0. See the changelog for a complete list of changes in cesium-native.
