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
