12 +setting and clearing the "Voltage unbalance" errors without delays
13 +{new CAN bus speed is not applied until the device is rebooted
14 +- logging the following new parameters: "UnibatState", "UnibatOperationalModeState", "Keyrun", "ChargeOn"
15 +- Unibat: ability to shutdown the battery if its SOC is too low (see the "External equipment - Unibat vehicle - Diagnostic parameters" section)
16 +- Unibat: change the resolution of parameters CC and DC from 0.01 to 0.1 Ah/bit
17 +- Unibat: do not turn on the amber lamp if the actual battery SOC is equal to the configured maximum operational SOC

27 +== Features ==
28 +
29 +* support for the Trolleybat vehicle (see the "External equipment - Trolleybat vehicle" section)
30 +
31 +== Improvements ==
32 +
33 +* checking the continuous charge current limit only if the "Use continuous charge current limit" flag is set in the "External equipment - Unibat vehicle - General parameters" section
34 +* Unibat: transition to charging mode according to the condition EESCD=7
35 +
36 +== Fixes ==
37 +
38 +* resolving the problem of completing the initialization process before the power switch voltage stabilizes
39 +* Unibat: prevent the "Charge request" and "Discharge request" signals from being reset if the Unibat vehicle goes offline (the signals are controlled in the Unibat state machine)

53 +== Features ==
54 +
55 +* 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)
56 +* new total charge counters (plus and minus)
57 +
58 +== Improvements ==
59 +
60 +* Unibat: new flag to set the custom value (=3) for the EESCD signal (see the "External equipment - Unibat vehicle - General parameters" section)
61 +* Unibat: new bit field to ignore internal errors that cause battery shutdown (see the "External equipment - Unibat vehicle - General parameters" section)
62 +* Unibat: sending a new packet containing the continuous charge current limit
63 +
64 +== Fixes ==
65 +
66 +* optimization of the logging process, minimizing the time to open the next log file if the current one is full
67 +* resolving the stability problem when the SD card is full
68 +* Unibat: prevent sending module online statuses if the power down condition is met
69 +* Unibat: small fixes

75 +== Improvements ==
76 +
77 +* turning on power switches with a delay of 1 second after reaching the supply voltage of 9V
78 +* Unibat: new flag that allows to hide the insulation testing status when repeating measurements (see the "External equipment - Unibat vehicle" section)
79 +* 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
80 +
81 +== Fixes ==
82 +
83 +* resolving the issue of false warnings indicating that the battery current exceeds the current limits (affects Unibat vehicle)
84 +* 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)
85 +* Unibat: resolving the issue of TP messages not being sent if the transport is already transmitting something at the time of the request
86 +* corrections of typos in parameter descriptions
