+'''New:'''\\
+openACC porting of timestep calculation. (modules, timestep, time_integration)
+
+'''Changed:'''\\
+openACC {{{loop}}} directives and {{{vector}}} clauses removed where they do not give performance improvements (concerning PGI compiler versions >= 13.6). (advec_ws, buoyancy, coriolis, diffusion_e, diffusion_s, diffusion_u, diffusion_v, diffusion_w, diffusivities, exchange_horiz, fft_xy, pres, production_e, transpose, tridia_solver, wall_fluxes)
+
+openACC {{{loop independent}}} clauses added. (boundary_conds, prandtl_fluxes, pres)
+
+openACC {{{declare create}}} statements moved after FORTRAN declaration statement. (diffusion_u, diffusion_v, diffusion_w, fft_xy, poisfft, production_e, tridia_solver)
+
+openACC {{{end parallel}}} replaced by {{{end parallel loop}}}. (flow_statistics, pres)
+
+openACC {{{kernels do}}} replaced by {{{kernels loop}}}. (prandtl_fluxes)
+
+output format for theta* changed to avoid output of ***** in the run-control file. \\
+'''Attention:''' Due to this modification, the format of the default run-control file has changed. (run_control, example_cbl_rc)
+
+'''Bugfix:'''\\
+Calculation of the advective timestep in case of vertically stretched grids has been corrected. \\
+'''Attention:''' Due to this modification, the contents of the default run-control output has changed. (timestep, example_cbl_rc)
