+'''Most important changes:''' atmosphere-ocean coupling has been improved and steering of dvr-software is more user-friendly now. Beside that, the release contains a lot of optimizations, changes, and bugfixes which have accumulated over the last months.
+
+The atmosphere-ocean coupling allows to use independent precursor runs in order to account for different spin-up times. The time when coupling has to be started is given by new inipar parameter {{{coupling_start_time}}}. The precursor ocean run has to be started using new '''mrun''' option "{{{-y}}}" in order to add the appendix "{{{_O}}}" to all output files. (check_for_restart, check_parameters, data_output_2d, data_output_3d, data_output_profiles, data_output_ptseries, data_output_spectra, data_output_tseries, header, init_coupling, modules, mrun, parin, read_var_list, surface_coupler, time_integration, write_var_list)
+
+Clipping of dvrp output implemented. Default colourtable for particles implemented, particle attributes (color, dvrp_size) can be set with new parameters {{{particle_color}}}, {{{particle_dvrpsize}}}, {{{color_interval}}}, {{{dvrpsize_interval}}}. Slicer attributes (dvrp) are set with new routine {{{set_slicer_attributes_dvrp}}} and are controlled with existing parameter {{{slicer_range_limits}}}. (init_dvrp, data_output_dvrp, modules, set_slicer_attributes_dvrp,  user_data_output_dvrp)
+
+Polygon reduction for topography and ground plate isosurface. Reduction level for buildings can be chosen with parameter {{{cluster_size}}}. (init_dvrp)
+
+Variables {{{bc_lr}}} and {{{bc_ns}}}  in most subroutines replaced by {{{LOGICAL}}} variables {{{bc_lr_cyc}}} and
+{{{bc_ns_cyc}}} for speed optimization. This gives a significant speedup of more than 10%. (check_parameters, diffusion_u, diffusion_v, diffusion_w, modules)
+
+Scripts have been adapted for machine lck (Yonsei Univ.). (mrun, mbuild, subjob)
+
+Additional timestep criterion in case of simulations with plant canopy. (timestep)
+
+Check for illegal entries in {{{section_xy}}}|{{{xz}}}|{{{yz}}} that exceed {{{nz+1}}}|{{{ny+1}}}|{{{nx+1}}}. (check_parameters)
+
+External pressure gradient can be used as driving force. (check_parameters, header, init_3d_model, modules, parin, prognostic_equations, read_var_list, write_var_list)
+
+New topography case ''\'single_street_canyon\'''. (header, init_grid, modules, parin, read_var_list, user_check_parameters, user_header, user_init_grid, write_var_list)
+
+Option to predefine a target bulk velocity for {{{conserve_volume_flow}}}. (check_parameters, header, init_3d_model, modules, parin, read_var_list, write_var_list)
+
+Option for user defined 2D data output in xy cross sections at z=nzb+1. (data_output_2d, user_data_output_2d)
+
+xy cross section output of surface heatfluxes (sensible and latent). (average_3d_data, check_parameters, data_output_2d, modules, read_3d_binary, sum_up_3d_data, write_3d_binary)
