+'''Changed:'''
+
+* lpm_advec: turbulent velocity fluctuations can be used (use_sgs_for_particles), terminal velocity is computed from a parameterization by Rogers et al. (1993)
+* lpm_droplet_collision: a new collision algorithm is available (collision_algorithm='all_or_nothing', 'average_impact' turns on the original algorithm)
+* lpm_collision_kernel: the PALM kernel has been removed. Terminal velocities are also computed by the parameterization of Rogers et al. (1993) (analogously to lpm_advec)
+* microphysics: Kessler bulk microphysics are not integrated in microphyics (i.e., calc_precipitation and impact_of_latent_heat are deleted). Microphysics can be steered via cloud_scheme with the following options: 'saturation_adjust' is a simple saturation adjustment scheme without precipitation, 'kessler' turns on the (one-moment) precipitation parametrization by Kessler (1996), 'seifert_beheng' the (two-moment) precipitation parameterization by Seifert and Beheng (2006).
+* several routines of the LPM (Lagrangian particle model): Tails are now removed.
+
+'''Bugfixes:'''
+
+* Calculation of the turbulent enhancement factor of collection efficiency is corrected
