10 -* support for the HYG Global CAN protocol version 2 (June 13, 2024)
11 -* calculation of regenerated energy
12 -* calculation of new lifetime parameters: average temperature, average charge/discharge currents, etc. See the counters in the "Service - Counters" section
13 -* new "Need acknowledge" warning signal that is set when a new record is created in the errors journal. The signal can be cleared in the "Service - Errors journal" section
14 -* 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)
15 -* new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Control - Cell balancing" section)
16 -* new Max-Min algorithm for calculating the final battery SOC in the "Control - SOC estimation" section
17 -* 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
18 -* 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)
19 -* 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)
20 -* ability to select errors that the device saves in the errors journal (see the "Service - Errors journal" section)

50 -* 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.
51 -* 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)
52 -* 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)
53 -* 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)
54 -* clearing the Discharging (AUX) signal if the cell voltage is too low (see the "Control - Discharge (AUX)" section)
55 -* new assignment "Close External 1" for the discrete inputs (see the "Signals - Input discrete signals - Assignments" section)
56 -* 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.
