### 2.3.0 ???
* Fixed normalization on Windows paths running the converter on Linux. [#150](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/150)
* Added ability to use the first material in the mtl file when the obj is missing `usemtl`. [#133](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/133)
* Fixed handling of unnormalized input normals. [#136](https://github.com/AnalyticalGraphicsInc/obj2gltf/pull/136)
