+'''New'''
+
+Added {{{diagnostic_quantities_mod}}} which allows an unified calculation of magnus formula and saturation mixing ratio. 
+The explicit calculation in the model parts is replaced by a function/subroutine call. 
+'''Change'''
+
+The model now calculates the saturation mixing ratio instead of saturation specific humidity. So the factor 1 - R_d/R_v vanishes.
+This change can have a (significant!) impact of results considering liquid phase. The difference of saturation mixing ratio and saturation specific humidity is less than 1-3% (depending on temperature and moisture). However, relative changes in liquid water are greater and can intensified by interactions with dynamics.
