4
5 * new balancing strategy that attempts to keep the temperature of BMS Logic devices below a set value by discharging cells with higher voltages first than others (see the "Control - Cell balancing" section)

7 == Fixes ==
8
9 * resolving the possible problem of saving device parameters
10 * resolving the problem of writing the device's working time to a non-volatile memory very often

16 * new algorithms in the Charging/Discharging controller that allow to control the Charging/Discharging contactor independently from the Charging and Discharging signals (see the "Control - Charge/Discharge" section). The new "Independent" algorithms are preferred in the battery systems with one contactor.
17 * selection of errors that cause reset of contactor control signals (see the "Control - Main contactor", "Control - Charge", "Control - Discharge", "Control - Charge/Discharge", "Control - Discharge (AUX)", "Control - Heater", "Control - Cooler", "Protections - General error", "Control - Charging status", "Control - Discharging status" sections)
18 * new "Current limit error" which is set if the battery current exceeds the charging or discharging current limits (see the "Protections - Charge current limit" and "Protections - Discharge current limit" sections)
19 * new parameter to select the method of calculating the battery voltage: sum the cell voltages or use the measured voltage before contactors (see the "Control - Common settings" section)
20 * clearing the Discharging (AUX) signal if the cell voltage is too low (see the "Control - Discharge (AUX)" section)
21 * new assignment "Close External 1" for the discrete inputs (see the "Signals - Input discrete signals - Assignments" section)
22 * new assignment "External 1" for the discrete outputs and power switches (see the "Signals - Output discrete signals - Assignments" and "Signals - Power switches - Assignments" sections). The "External 1" output is directly controlled by the "Close External 1" command.

26 * rearrangements in the settings sections, which are made to simplify the setup process
