10 +== Improvements ==
11 +
12 +* Unibat: preventing the reset of the HVBPITS and HVBPITR signals if the device shutdown was caused by the insulation fault
13 +
14 +== Fixes ==
15 +
16 +* Unibat: charge current limit protection is disabled in charge mode only when the "Use continuous charge current limit" flag is set
17 +* Unibat: discharge current limit protection is enabled regardless of whether the battery is in discharge or charge mode

23 +== Improvements ==
24 +
25 +* setting and clearing the "Voltage unbalance" errors without delays
26 +* new CAN bus speed is not applied until the device is rebooted
27 +* logging the following new parameters: "UnibatState", "UnibatOperationalModeState", "Keyrun", "ChargeOn"
28 +* Unibat: ability to shutdown the battery if its SOC is too low (see the "External equipment - Unibat vehicle - Diagnostic parameters" section)
29 +* Unibat: change the resolution of parameters CC and DC from 0.01 to 0.1 Ah/bit
30 +* Unibat: do not turn on the amber lamp if the actual battery SOC is equal to the configured maximum operational SOC
31 +
32 +== Fixes ==
33 +
34 +* resolving the problem of completing the initialization process before the power switch voltage stabilizes

48 +
49 +== Fixes ==
50 +
51 +* resolving the problem of completing the initialization process before the power switch voltage stabilizes
52 +* 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)
