Cesium upgrade from 1.92.0 to 1.113.0. You can see the full list of changes here

https://github.com/CesiumGS/cesium/blob/main/CHANGES.md#1113---2024-01-02

High-level changes that may be of interest:

Breaking changes

Firefox 114 is now the minimum Firefox version required to run CesiumJS. #11400

Additions

Vertical exaggeration can now be applied to a Cesium3DTileset. Exaggeration of Terrain and Cesium3DTileset can be controlled simultaneously via the new Scene properties Scene.verticalExaggeration and Scene.verticalExaggerationRelativeHeight. #11655
Added createGooglePhotorealistic3DTileset to create a 3D tileset streaming Google Photorealistic 3D Tiles.
Added smooth zoom with mouse wheel. #11062
CesiumJS now defaults to using a WebGL2 context for rendering. WebGL2 is widely supported on all platforms and this results in better feature support across devices, especially mobile.
- WebGL1 is supported. If WebGL2 is not available, CesiumJS will automatically fall back to WebGL1.
- In order to work in a WebGL2 context, any custom materials, custom primitives or custom shaders will need to be upgraded to use GLSL 300.
- Otherwise to request a WebGL 1 context, set requestWebgl1 to true when providing ContextOptions as shown below:
```
const viewer = new Viewer("cesiumContainer", {
contextOptions: {
requestWebgl1: true,
},
});
```
Added experimental support for 3D Tiles voxels with the 3DTILES_content_voxels extension. The current implementation is intended for development use, as the voxel format has not yet been finalized and is subject to breaking changes without deprecation.
Added support for I3S 3D Object and IntegratedMesh Layers. #9634
CesiumJS has switched to a new architecture for loading glTF models and tilesets to enable:
- User-defined GLSL shaders via CustomShader
- Support for 3D Tiles Next metadata extensions: EXT_structural_metadata, EXT_mesh_features and EXT_instance_features
- Support for EXT_mesh_gpu_instancing
- Support for EXT_meshopt_compression
- Texture caching across different tiles
- Numerous bug fixes
Usage notes for the new glTF architecture:
- Those using ModelExperimental.fromGltf() should now use Model.fromGltf().
- The enableModelExperimental flag was removed, as tilesets and entities always use the new architecture.
- The new implementation of Model uses the same public API as before, so no other changes are necessary.
Models and tilesets that use the CESIUM_primitive_outline extension can now toggle outlines at runtime with the showOutline property. Furthermore, the color of the outlines can now be controlled by the outlineColor property. #10506
Improved rendering of ground and sky atmosphere. #10063

Fixes

Changes the default RequestScheduler.maximumRequestsPerServer from 6 to 18. This should improve performance on HTTP/2 servers and above. #11627
Fixed Repeated URI parsing slows 3D Tiles performance #11197. Together with #11211, this can reduce tile parsing time by as much as 25% on large tilesets
Fixed atmosphere rendering performance issue. 10510

@nf-s There is no main branch in terriajs-cesium repo https://github.com/TerriaJS/cesium/. I can see two major branches

terriajs
terriajs-new

terriajs currently uses v6.2.0 of terriajs-cesium. What is the procedure of releasing new version of terriajs-cesium?

Since we are testing the new releases, should we make them alpha versions?
