 ### 1.0.47
 
 * The `name` of a feature from a CSV file is now taken from a `name` or `title` column, if it exists.  Previously the name was always "Site Data".
+* Underscores are now replaced with spaces in the feature info panel for `GeoJsonCatalogItem`.
 * Updated to [Cesium](http://cesiumjs.org) 1.15.  Significant changes relevant to TerriaJS users include:
   * Added support for the [glTF 1.0](https://github.com/KhronosGroup/glTF/blob/master/specification/README.md) draft specification.
   * Added support for the glTF extensions [KHR_binary_glTF](https://github.com/KhronosGroup/glTF/tree/master/extensions/Khronos/KHR_binary_glTF) and [KHR_materials_common](https://github.com/KhronosGroup/glTF/tree/KHR_materials_common/extensions/Khronos/KHR_materials_common).
