17 -* resolving the issue of ill-considered reduction of the battery SOC level when the cell voltage is close to the level corresponding to SOC=0% (due to the flow of a large discharge current leading to the high voltage drop on the cells)

39 -* new parameter for setting the condition for starting balancing: automatically (regardless of the command) or on the balancing request (see the "Control - Cell balancing" section)
40 -* new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Control - Cell balancing" section)
41 -* new Max-Min algorithm for calculating the final battery SOC in the "Control - SOC estimation" section
42 -* new flags in the "Protections - Undervoltage" and "Protections - Overvoltage" sections which allow using the calculated open circuit cell voltage instead of the actual voltage to detect the "Undervoltage" and "Overvoltage" errors, respectively
43 -* ability to check the "Ready to charge" and "Ready to discharge" signals to control the charging and discharging contactors (see the "Control - Charge" and "Control - Discharge" sections)
44 -* improved control of the precharging contactor, which can precharge capacitive load using multiple attempts and detect high power dissipated in the precharge resistor (see the "Control - Precharge" section)
45 -* ability to select errors that the device saves in the errors journal (see the "Service - Errors journal" section)
46 -* new parameter that limits the number of battery cycles; when the number of battery cycles exceeds the limit, the BMS cannot close the charging and discharging contactors (see the "Service" section, log in under the service account)

48 -== Improvements ==

54 -* using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals
55 -* resolving the problem of incorrect software signal addresses in the Modbus holding register table
