 - `compareparameters.sh` is deprecated, use `getparameterlist.py` instead.
 - `replace_property_macros.sh` is removed.
 - `isOnWallAtPos` and `isOnWall` are no longer used in the RANS models to designate wall boundaries. These boundaries are now directly set in the RANSBoundaryTypes using the setWall() function.
+- the `temperature` and `extrusionFactor` interfaces in the problem class have been deprecated and have been moved to the spatial parameters.
+- Porous medium flow models should now inherit from the new base spatial parameters that can be found in the folder `dumux/porousmediumflow/`, which allow users to overload the new `temperature` and `extrusionFactor` interfaces.
+- Free flow and pore network models now also expect the user problems to expose spatial parameters, in which `gravity`, `temperature` and `extrusionFactor` are defined. The respective problem interfaces have been deprecated.
