10 +== Features ==
11 +
12 +* new flag that forces the "Ready to discharge" signal to clear when the "Low SOC" signal is generated (see the "Control - Discharging status" section)
13 +* new input signal "Close External 2" which generates the new internal signal "External 2" which can be assigned to a discrete output or a power switch (see the "Signals - Input discrete signals - Assignments", "Signals - Output discrete signals - Assignments", and "Signals - Power switches - Assignments" sections)
14 +* ability to configure the generation of "External 1" and "External 2" signals based on other internal signals as an alternative to the "Close External 1" and "Close External 2" commands (see the "Signals - External 1-2 signals" section)
15 +
16 +== Improvements ==
17 +
18 +* new flags for generating the "Ready to charge" and "Ready to discharge" signals using the actual cell voltage instead of the calculated open circuit voltage (see the "Control - Charging status" and "Control - Discharging status" sections)
19 +* new flag the forces the device to wait for the "Charge request" and "Discharge request" signals to clear before reconnecting power contactors if the connection to the BMS Main X device is temporarily lost (see the "External equipment - BMS - Main X" section)
20 +* new CAN bus speed is not applied until the device is rebooted
21 +* logging the following new parameters: "Keyrun", "ChargeOn"
22 +
23 +== Fixes ==
24 +
25 +* resolving the problem of charge, discharge, and charge/discharge contactors closing when the "Precharge request" signal is set
26 +* resolving the problem of completing the initialization process before the power switch voltage stabilizes
27 +* resolving the problem of resetting the SOC of some cells to zero when starting the device
