 ### 1.91 - 2022-03-01
 
+##### Breaking Changes :mega:
+
+- Fixed an inconsistently handled exception in `camera.getPickRay` that arises when the scene is not rendered. `camera.getPickRay` can now return undefined. [#10139](https://github.com/CesiumGS/cesium/pull/10139)
+
 ##### Additions :tada:
 
 - Added MSAA support for WebGL2. Enabled on viewer creation with the multisampling rate as the `msaaSamples` option and can be controlled through `Scene.msaaSamples`.
