50 -* new algorithm 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" algorithm is preferred in the battery systems with one contactor
51 -* 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
52 -* new Max-Min algorithm for calculating the final battery SOC in the "Control - Calculation" section
53 -* 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)
54 -* ability to exclude errors from being saved in the error journal (see the "Service - Errors journal" section)
55 -* ability to restart the device according to a specified schedule at the moment when the battery system is preparing to charge
56 -* new error "High contactor temperature" that can be used to open the specified contactor to prevent it from overheating (see the "Protections - High contactor temperature" section)
57 -* new internal signal "Coolant pump" that can be assigned to a relay or discrete output (for signal settings, see the "Control - Coolant pump" section)
58 -* new flags indicating the readiness of battery modules to join for charging and discharging (see the "Modules" section)
59 -* new flag to set the "Voltage unbalance" errors for battery modules that are not ready to charge or discharge (see the "Protections - Voltage unbalance (in any state)" section)
60 -* initial support for Pylontech inverters
61 -* extension of the CANopen dictionary to provide additional information for the BMS Display (device serial number, battery serial number, battery address, Wi-Fi and LAN addresses, SOH, capacity, etc.)
