21 -* new parameter for setting the condition for starting balancing: automatically (regardless of the command) or on the balancing request (see the "Cells - Cell balancing" section)
22 -* new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Cells - Cell balancing" section)
23 -* new assignment "Balancing request" for the discrete inputs (see the "Signals - Input signals" section)
24 -* new Max-Min algorithm for calculating the final battery SOC in the "Cells - SOC estimation" section
25 -* new algorithms "Automatic" and "On command" for the main contactor (see the "Cells - Main contactor" section)
26 -* new assignment "Close Main contactor" for the discrete inputs to close the main contactor by a command
27 -* new assignment "Close External 1" for the discrete inputs (see the "Signals - Input signals" section)
28 -* new assignment "External 1" for the discrete outputs and relays (see the "Signals - Output signals" section). The "External 1" output is directly controlled by the "Close External 1" command.
29 -* new "Precharge error" flag that is set when precharging cannot be completed
30 -* new flags in the "Protections - Undervoltage protection" and "Protections - Overvoltage protection" sections which allow using the calculated open circuit cell voltage instead of the actual voltage to detect the "Undervoltage" and "Overvoltage" errors, respectively
31 -* ability to check the "Ready to charge" and "Ready to discharge" signals to control the charging and discharging contactors (see the "Cells - Charging control" and "Cells - Discharging control" sections)
32 -
33 -== Improvements ==
34 -
35 -* ignoring the "Need acknowledge" flag when generating Modbus input register 0x2128 ("Error")
36 -* explicit flags to enable the use of the charging current limit for fast and/or normal charging when using the CCS Fast charge controller (see the "External equipment - CCS Fast charge controller" section)
37 -* improving resistance calculation
38 -
39 -== Fixes ==
40 -
41 -* resolving the issue where the "Need acknowledge" signal is not set if any of the device errors are not acknowledged in the error journal
42 -* using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals

58 -* new additional heater controller (see the "Protections - Heater (AUX) control" section), which generates the "Heater (AUX)" signal, which can be assigned to a discrete output or relay
59 -
60 -== Improvements ==
61 -
62 -* 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 "Cells - Cell balancing" section)
