11 -
12 -* new parameters allowing to set different delays for battery discharge mode to detect the overcurrent error (see the "Protections - Overcurrent protection" section)
13 -* new flag that sets whether the BMS should wait for confirmation messages from the Combilift truck to start charging or not (see the "External equipment - Combilift truck" section)

32 -== Features ==
33 -
34 -* 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)
35 -* new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Cells - Cell balancing" section)
36 -* new assignment "Balancing request" for the discrete inputs (see the "Signals - Input signals" section)
37 -* new Max-Min algorithm for calculating the final battery SOC in the "Cells - SOC estimation" section
38 -* new algorithms "Automatic" and "On command" for the main contactor (see the "Cells - Main contactor" section)
39 -* new assignment "Close Main contactor" for the discrete inputs to close the main contactor by a command
40 -* new assignment "Close External 1" for the discrete inputs (see the "Signals - Input signals" section)
41 -* 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.
42 -* new "Precharge error" flag that is set when precharging cannot be completed
43 -* 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
44 -* 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)
45 -
46 -== Improvements ==
47 -
48 -* ignoring the "Need acknowledge" flag when generating Modbus input register 0x2128 ("Error")
49 -* 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)
50 -* improving resistance calculation
51 -
52 -== Fixes ==
53 -
54 -* resolving the issue where the "Need acknowledge" signal is not set if any of the device errors are not acknowledged in the error journal
55 -* using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals
