 - **The `defaultBlockType` of the `Html` serializer is now called `defaultBlock`.** This is just to make it more clear that it supports not only setting the default `type` but also `data` and `isVoid`.

+- **Slate models now have `Model.fromJSON(object)` and `model.toJSON()` methods.** These methods operate with the canonical JSON form (which used to be called "raw"). This way you don't need to `import` a serializer to retrieve JSON, if you have the model you can serialize/deserialize.

+- **The `state.activeMarks` returns the intersection of marks in the selection.** Previously there was only `state.marks` which returns marks that appeared on _any_ character in the selection. But `state.activeMarks` returns marks that appear on _every_ character in the selection, which is often more useful for implementing standard rich-text editor behaviors.
