10 +== Improvements ==
11 +
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.)
21 +
22 +== Fixes ==
23 +
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
27 +* small internal fixes

33 +
34 +== Features ==
35 +
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)
