All pointer based methods have been removed. Now we have only: void setGeometry( const QgsGeometry& geom ) and QgsGeometry geometry() const Benefits include avoiding a whole lot of tricky pointer lifetime issues, potential memory leaks, and finally closing #777, which has survived for over 9 years!... Impacts on PyQGIS code: - no more need for the messy g = QgsGeometry( feature.geometry() ) workaround, just use g = feature.geometry() instead - IMPORTANT: you can no longer test whether a feature has geometry using `if f.geometry():`, since QgsFeature::geometry() will *always* return an object. Instead, use `if not f.geometry().isEmpty():`, or preferably the new method `if not f.hasGeometry():` Fix #777
