9 +
10 +== Improvements ==
11 +
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
18 +
19 +== Fixes ==
20 +
21 +* resolving the problem of completing the initialization process before the power switch voltage stabilizes

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
