 = Summary of relevant code changes, new features =
+* The basic equations in PALM have been changed to an anelastic approximation. This allows for an air-density change with height and enables PALM to simulate deep convection. The new functionality can be steered with the initialization parameter {{{approximation}}}. A Boussinesq approximation of the basic equations can still be used and is in fact the models default configuration. Note that all internal flux quantities are now quantities per unit volume instead of per unit mass (not kinematic anymore). The input and output of flux quantities with regard to their physical interpretation (e.g. units) can be steered by the initialization parameters {{{flux_input_mode}}} and {{{flux_output_mode}}}.
+* The bulk cloud microphysics model code has been modularized and its capabilities can now be controlled within a new namelist called {{{bulk_cloud_parameters}}}. 
+ - It is now allowed to enable the bulk cloud model and use complex topography at the same time.
 * ocean code has been modularized and put into new file {{{ocean_mod.f90}}}. Turbulence generation by wave breaking, as well as the Stokes drift have been implemented in the default code. New namelist {{{ocean_parameters}}}
 * introduced changes to {{{date_and_time_mod.f90}}} for calculations of time indices such as hour of the day or month of the year, according to the running time of the simulation
