+Version History
+---------------
+
+### gproshan 3.0.0
+- Upgraded version of the sparse mesh coding with feature aware sampling module and published paper reference.
+- Updated save mesh with options for file types, normals, and point-cloud.
+- Added render option using [Embree](https://www.embree.org/) ray tracing.
+- Implemented the loading and rendering of point-clouds.
+- Added heatmap viewer options and loading vertex color from a file.
+- New user interface implemented with [ImGui](https://github.com/ocornut/imgui).
+- Viewer upgraded using GLEW, GLFW, and GLM.
