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)

The new "Independent" algorithms are preferred in the battery systems with one contactor.
