 - __Compositional Staggered__: The staggered discretization method has been updated to fix inconsistencies in handling density when evaluating diffusive boundary fluxes. In addition, a total mass balance is now always considered, rather than a total mole balance.
 - __Parameters__: The template argument for `getParam` and `getParamFromGroup` now defaults to `std::string`, such that for string parameters one can simply write `const auto param = getParam("MyParam");`
 - __Compositional Freeflow FCSFV__: Compositional transport has been implemented for the overhauled face-centered staggered finite volume scheme (FCSFV) discretization method. Ported tests are available in the testing suite.
+- __GridGeometry__: No longer store the corners/geometry for scv/scvfs also for cc-mpfa and staggered discretizations. This improves the memory footprint a lot. Geometries can be obtained via the local view of the grid geometry.
