[GenerateAuthoringComponent]+unsafe codegen 0.50

[GenerateAuthoringComponent] code-gen doesn't seem to cater for unsafe code.
Is there a setting somewhere for this? I couldn't find anything in the upgrade guide.

Component

Code (CSharp):

1. [GenerateAuthoringComponent]
2. public unsafe struct BuffComp : IComponentData
3. {
4.     public fixed float value[4];
5. }

Generated Component

Code (CSharp):

1. public class BuffCompAuthoring : UnityEngine.MonoBehaviour, Unity.Entities.IConvertGameObjectToEntity
2. {
3.     [Unity.Entities.RegisterBinding(typeof(BuffComp), "value")]
4.     public float *value;
5.     public void Convert(Unity.Entities.Entity __entity, Unity.Entities.EntityManager __dstManager, GameObjectConversionSystem __conversionSystem)
6.     {
7.         BuffComp component = default(BuffComp);
8.         component.value = value;
9.         __dstManager.AddComponentData(__entity, component);
10.     }
11. }

Error

Code (CSharp):

1. Temp/GeneratedCode/Assembly-CSharp/BuffComp__AuthoringComponent_837250236.g.cs(4,12): error CS0214: Pointers and fixed size buffers may only be used in an unsafe context
