27 * new parameter for setting the type of network to which the BMS GSM communication module connects (see the "Connectivity - Cellular" section)
28 * new flag that controls whether to use open circuit voltage or actual voltage when determining the voltage unbalance error (see the "Protections - Voltage unbalance (in any state)" section)

32
33 == Improvements ==
34
35 * dynamic calculation of data transfer schedule for optimal communication with a large number of battery modules
36 * ability to complete device initialization after the set timeout has expired and the minimum number of modules has been detected (see the "Control - Initialization" section)

47
48 == Features ==
49
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.)
62
63 == Improvements ==
64
65 * ability to finish device initialization even if the number of battery modules found is less than the number of modules enabled (see the "Control - Modules" section)
66 * placing the device input signals to the "Battery" section and adding raw discrete inputs to the "Signals" section
67
68 == Fixes ==
69
70 * resolving the issue of ignoring the minimum number of battery modules allowed to join located in the "Control - Discharge" section
71 * 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
72 * small internal fixes
