Change Log
==========
### 3.0.0 ????-??-??
* Breaking changes
* The `--materialsCommon` flag has been removed. Use `--unlit` instead which uses the `KHR_materials_unlit` extension. [#152](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/152)
### 2.3.2 2018-11-02
* Improved handling of primitives with different attributes using the same material. Materials are now duplicated. [#162](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/162)
