10 +== Fixes ==
11 +
12 +* Unibat: do not send the insulation error DTC if the IMD goes offline when the battery system is in the shutdown mode

18 +== Features ==
19 +
20 +* new profile section with global battery status, which includes total charge and energy counters, total operating time, contactor opening count, etc. (see the "Profile" tab in the Unified monitor)
21 +* new total charge counters (plus and minus)
22 +
23 +== Improvements ==
24 +
25 +* Unibat: new flag to set the custom value (=3) for the EESCD signal (see the "External equipment - Unibat vehicle - General parameters" section)
26 +* Unibat: new bit field to ignore internal errors that cause battery shutdown (see the "External equipment - Unibat vehicle - General parameters" section)
27 +* Unibat: sending a new packet containing the continuous charge current limit
28 +
29 +== Fixes ==
30 +
31 +* optimization of the logging process, minimizing the time to open the next log file if the current one is full
32 +* resolving the stability problem when the SD card is full
33 +* Unibat: prevent sending module online statuses if the power down condition is met
34 +* Unibat: small fixes

40 +== Improvements ==
41 +
42 +* turning on power switches with a delay of 1 second after reaching the supply voltage of 9V
43 +* Unibat: new flag that allows to hide the insulation testing status when repeating measurements (see the "External equipment - Unibat vehicle" section)
44 +* expansion of the list of parameters that are reset to default values when the device is powered on while holding the button on the board. The following parameters are affected: all CAN1 (ext) settings; all CAN2 (int) settings; all CAN3 (BMS) settings; all RS-485-1 (Modbus) settings; LAN settings: IP mode, IP address, Netmask, Gateway address
45 +
46 +== Fixes ==
47 +
48 +* resolving the issue of false warnings indicating that the battery current exceeds the current limits (affects Unibat vehicle)
49 +* Unibat: changes that make it so that the output period is responsible for only 4 messages, not for all messages (see the "External equipment - Unibat vehicle" section)
50 +* Unibat: resolving the issue of TP messages not being sent if the transport is already transmitting something at the time of the request
51 +* corrections of typos in parameter descriptions

58 +
59 +* new parameters for switching to the sum of battery modules' currents if the current sensor error is detected or the sensor is saturated (see the "Inputs - Current sensor" section)
60 +* new flag allowing to swap CAN2 (int) and CAN3 (BMS) interfaces (see the "Connectivity" section under the service account)

69 +
70 +== Improvements ==
71 +
72 +* new flag enabling fast current measurements (see the "Signals - Current sensor" section)
73 +* new parameters to ignore the specified errors when setting the critical error (see the "Protections - Critical error" section)
74 +* displaying HV calibration values for the service account (see the "Service - Calibration" section)
75 +* Unibat: structuring parameters into subgroups: "General parameters", "Battery parameters", "Diagnostic parameters", "Power limiting parameters", "Battery version" (see the "External equipment - Unibat vehicle" section)
