Highlights include:

• Fixes incorrect polygon culling in 2D scene mode. https://github.com/CesiumGS/cesium/issues/1552
• Fixes material flashing when changing properties. https://github.com/CesiumGS/cesium/issues/1640, https://github.com/CesiumGS/cesium/issues/12716

• Fixes an exception when removing a Gaussian splat tileset from the scene primitives when it has more than one tile. https://github.com/CesiumGS/cesium/pull/12726
• Fixes rendering of Gaussian splats when they are scaled by the glTF transform, tileset transform, or model matrix. https://github.com/CesiumGS/cesium/issues/12721, https://github.com/CesiumGS/cesium/issues/12718
• Fixes Gaussian splats orientation with respect to glTF up-axis by updating spz-loader to version 0.3.0. https://github.com/CesiumGS/cesium/issues/12737, https://github.com/CesiumGS/cesium/issues/12749
• Fixes label background translucency issue. https://github.com/CesiumGS/cesium/issues/12673
• Add wrapR property to Sampler and Texture3D, to support the newly added third dimension wrap.https://github.com/CesiumGS/cesium/pull/12701
• Added the ability to load a specific changeset for iTwin Mesh Exports using ITwinData.createTilesetFromIModelId https://github.com/CesiumGS/cesium/issues/12778
• Updated all of the ITwinData.* functions to accept an options parameter instead of individual arguments to avoid confusion with multiple optional arguments. There is a fallback to the old signature that will be removed in 1.133 https://github.com/CesiumGS/cesium/issues/12778
