1.121 - 2024-09-03

Highlights include:

- Enable MSAA by default with 4 samples. This smooths jagged edges for increased visual realism. [#12158](https://github.com/CesiumGS/cesium/pull/12158)
- Switched the default (non-HDR) tonemapping for models, atmosphere, and globe from ACES to [PBR Neutral Tonemap from Khronos](https://github.com/KhronosGroup/ToneMapping/tree/main/PBR_Neutral). The widens the gamut of possible colors, and provides more consistent color appearances across renderers. [#12160](https://github.com/CesiumGS/cesium/pull/12160)
- Expose the `tonemapper` and `exposure` properties of `PostProcessStageCollection` to allow changing the tonemap used when HDR is turned on. This defaults to the [PBR Neutral Tonemap from Khronos](https://github.com/KhronosGroup/ToneMapping/tree/main/PBR_Neutral) [#12160](https://github.com/CesiumGS/cesium/pull/12160)
- Added `WaterMask` globe material, which visualizes areas of water or land based on the terrain's water mask. [#12149](https://github.com/CesiumGS/cesium/pull/12149)
- Fixed several bugs with PBR lighting for more realistic rendering. [#12100](https://github.com/CesiumGS/cesium/pull/12100), [#12116](https://github.com/CesiumGS/cesium/pull/12116), and [#12118](https://github.com/CesiumGS/cesium/pull/12118)
