 -General changes
+  - Add new lofting algorithm to create wing surfaces with rounded segments [#1284](https://github.com/DLR-SC/tigl/pull/1338)
   - TiGLCreator: Draw option menus are now updated when adding new wings or fuselages. 
   - TiGLCreator: Bi-directional selection of shapes via the GUI or the CPACSTree is supported now [#1275](https://github.com/DLR-SC/tigl/issues/1275).
   - TIGLCreator: Use NACA profiles and standard profiles in the TIGLCreator templates ([#1367](https://github.com/DLR-SC/tigl/issues/1367))
