+### Fixed
+- Blendshapes naming in FBX so that multiple blendshapes all import correctly in Maya.
+- Don't override transforms when creating FBX Linked Prefab, so that the prefab updates properly when the FBX transforms are modified.

 ## [3.0.1-preview.2] - 2020-01-22
 ### Added
 - Added option to export geometry when recording with the FBX recorder (in previous version geometry was always exported).
