12 -* new parameter that sets the delay before measuring the current to determine that precharge is finished (see the "Control - Precharge" section)
13 -* ability to exclude errors from being saved in the error journal (see the "Service - Errors journal" section)
14 -* new flags indicating the readiness of battery modules to join for charging and discharging (see the "Modules" section)
15 -* 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)
16 -* Unibat: new parameters setting the BMS and VCU addresses (see the "External equipment - Unibat vehicle" section)
17 -* Unibat: new flag to invert the discharge current limit sent to the vehicle (see the "External equipment - Unibat vehicle" section)
18 -* Unibat: using the difference between the maximum and minimum temperatures among all cells as an input for the coolant pump controller
19 -* Unibat: automatically switch from discharging to charging mode if the CHARGE_ON signal or the charging station command is set (without rejoining the battery)
20 -* 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.)

24 -* resolving the issue of ignoring the minimum number of battery modules allowed to join located in the "Control - Discharge" section
25 -* resolving the issue of joining battery modules the number of which must be greater than or equal to the minimum value specified in the settings
26 -* making the service reset function work properly

36 -* 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
37 -* 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
38 -* new Max-Min algorithm for calculating the final battery SOC in the "Control - Calculation" section
39 -* 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)
40 -* ability to select errors that the device saves in the errors journal (see the "Service - Errors journal" section)
41 -
42 -== Improvements ==
43 -
44 -* ability to finish device initialization even if the number of battery modules found is less than the number of modules enabled
45 -* ability to configure and monitor the device via the CAN1 (ext) bus
46 -* placing the device input signals to the "Battery" section and adding raw discrete inputs to the "Signals" section
47 -* Unibat: support for functional description v3.5 (protocol v1.5)
