10 +== Features ==
11 +
12 +* 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)
13 +* new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Cells - Cell balancing" section)
14 +* new assignment "Balancing request" for the discrete inputs (see the "Signals - Input signals" section)
15 +* new Max-Min algorithm for calculating the final battery SOC in the "Cells - SOC estimation" section
16 +* new algorithms "Automatic" and "On command" for the main contactor (see the "Cells - Main contactor" section)
17 +* new assignment "Close Main contactor" for the discrete inputs to close the main contactor by a command
18 +* new assignment "Close External 1" for the discrete inputs (see the "Signals - Input signals" section)
19 +* 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.
20 +* new "Precharge error" flag that is set when precharging cannot be completed
21 +* 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
22 +* 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)
23 +
24 +== Improvements ==
25 +
26 +* ignoring the "Need acknowledge" flag when generating Modbus input register 0x2128 ("Error")
27 +* 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)
28 +* improving resistance calculation
29 +
30 +== Fixes ==
31 +
32 +* resolving the issue where the "Need acknowledge" signal is not set if any of the device errors are not acknowledged in the error journal
33 +* using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals
