@@ -5,6 +5,43 @@ All notable changes to this project will be documented in this file.

+## Upcoming - [3.16.0]
+
+CityDoctor now supports the import, export and validation of CityGML 3.0 files.
+
+#### CityGML Object parsing
+
+- CityDoctor is now capable of parsing and validating the following CityGML objects:
+
+    - Tunnel, TunnelParts, TunnelHollows and TunnelInstallations
+    - BuildingRooms, BuildingFurniture, BuildingStoreys and BuildingUnits
+    - BridgeRooms and BridgeFurniture
+    - CityFurniture
+    - GenericCityObjects
+
+- CityDoctor now supports ImplicitGeometries and CompositeSurfaces.
+
+- Data from CityDoctor's internal model will now be exported to the same CityGML version as
+the input file, rather than always exporting it to CityGML 2.0.
+
+
+#### CityDoctorGUI
+
+- Featuretabs for Tunnel, CityFurniture and other CityObjects were added.
+
+- QoL improvements:
+  - Added a north arrow to the mesh view.
+  - The camera of the mesh view can now be dragged by holding the right mouse button.
+  - Added a button which resets the camera view back to the initial state.
+  - Added a button to toggle hiding of roof BoundarySurfaces in the mesh view.
+  - Feature-tabs will now be greyed out if they contain no objects.
+  - Added a view-tab for GenericAttributes
+
+
+### Fixed
+
+- Fixed a TreeNode text color bug, which showed unchecked objects as being already validated.
+- Fixed an oversight in the CityGML version number parsing
