+- [FIXED] runopp(init="results") now preserves the warm-start vector in the PIPS-backed AC OPF solver
+- [ADDED] added more functions to diagnostic
+- [ADDED] check to check if vkr_percent values are reasonable (see issue #786).
+- [FIXED] cim2pp shift_lv_degree was translated from wrong entry
+- [FIXED] UnboundLocalError in _from_ppc_branch when creating impedance elements
+- [ADDED] LTDS support
+- [FIXED] ucte2pp: voltage setpoints from gens connected to the same busbar are now averaged
+- [FIXED] ucte2pp: small X values are clipped to 0.05 Ohm (according to UCTE-DEF) to increase convergence
+- [FIXED] ucte2pp: symmetrical tap changers are now handled as symmetrical tap changers in pandapower (not ideal phase shifters)
+- [FIXED] ucte2pp: prevent nan values for impedances and transformers for B/G/P_fe/i0
+- [FIXED] cim2pp: CimConverter backwards-compatible (default value for cin_version)
+- [FIXED] jao converter: calculation of trafo parameters is based on primary side (hv) now
+- [ADDED] toolbox: :code:`get_all_elements` returns all elements of a pp.pandapowerNet as a DataFrame
