9 +
10 +== Improvements ==
11 +
12 +* turning on power switches with a delay of 1 second after reaching the supply voltage of 9V
13 +* ability to generate the "Logic count error" also during BMS initialization (scanning of BMS Logic devices); new parameters for setting delays before/after generating/clearing the error (see the "Protections - Logic count" section)
14 +* 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 RS-485-1 (Modbus) settings; LAN settings: IP mode, IP address, Netmask, Gateway address

23 +
24 +== Features ==
25 +
26 +* new algorithm for detecting loss of wire connection to battery cells
27 +* new protection for detecting battery cell imbalance (see the "Protections - Cell imbalance" section)
28 +* new "Main X offline" error indicating loss of connection with the BMS Main X device
29 +
30 +== Improvements ==
31 +
32 +* new flag enabling fast current measurements (see the "Signals - Current sensor" section)
33 +* new parameters that control setting/clearing the "Ready to charge" and "Ready to discharge" signals based on the charge and/or discharge current limits (see the "Control - Charging status" and "Control - Discharging status" sections)
34 +* new parameters to ignore the specified errors when setting the critical error (see the "Protections - Critical error" section)
35 +* displaying HV calibration values for the service account (see the "Service - Calibration" section)

43 +* support for sending battery state and events via MQTT protocol via Wi-Fi or cellular network (see the "Service - MQTT" section)
44 +
45 +== Improvements ==
46 +
47 +* support for secure (TLS) connections in BMS GSM v1 and v2 drivers
48 +
49 +== Fixes ==
50 +
51 +* synchronization of the precharge procedure with the charge/discharge algorithms, so that precharge is stopped if charging and discharging are prohibited
