While reading the https://docs.unity3d.com/Manual/UpgradeGuide56.html I jumped to the Unity Blog reference.
In the final example, the line public class SerializationAPICallBehaviour : MonoBehaviour
should be moved inside the example block
Kind regards.
On the same page,[ https://docs.unity3d.com/Manual/UpgradeGuide56.html](http:// https://docs.unity3d.com/Manual/UpgradeGuide56.html) there is the “Mixed mode lighting has evolved” paragraph. It introduces some new lighting modes and links to the Unity - Manual: Lighting where there is no direct reference link.
Right now, these modes are covered only in a draft doc google document, [5.6 BETA] Light Modes - Google Docs
e.g. Subtractive mode: [DRAFT 5.6: VERSION 2] Subtractive Mode - Google Docs
Perhaps a link to the google document could prove useful until the google doc data are incorporated in the online documentation.
