* `System.WeakReference<T>` is now available in the sandbox.
* `IClydeViewport` now has an `Id` and `ClearCachedResources` event. Together, these allow you to properly cache rendering resources per viewport.
* Added a new entity yaml deserialization option (`SerializationOptions.EntityExceptionBehaviour`) that can optionally make deserialization more exception tolerant.
* `PointLightComponent` now has two fields, `falloff` and `curveFactor`, for controlling light falloff and the shape of the light attenuation curve.
### Bugfixes

* The client now logs an error when attempting to send a network message without server connection. Previously, it would be silently dropped.
* The function used for pointlight attenuation has been modified to be c1 continuous as opposed to simply c0 continuous, resulting in smoother boundary behavior.
