Support and Display of EPSG Area of Use Polygon data
Area of Use polygons allow developers to create a method for guiding users with the most appropriate coordinate system or transformation for an area based geopolitical bounding polygons that follow the borders of countries and similar areas around the world. These objects can be viewed in the QT dialogues for selecting coordinate system.

Integration in the transformation picker dialog to display these polygons while selecting transformations
Supports loading of EPSG polygons into viewers
Can also be used to filter results for transformation

Completely reworked Vertical Coordinate system handling
This allows more flexible transformation options when working with high accuracy elevation based data.

Enhanced PDC interface to calculate bounds of loaded data and filter coordinate systems and transformations
