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)

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

57 -== Features ==
58 -
59 -* new protection checking that the sum of cell voltages is equal to the voltage before contactors (the "High voltage 1" value). If this is not the case, the error "Battery voltage mismatch" is generated (see the "Protections - Battery voltage" section)
60 -* new protection checking that the number of cell temperature sensors is equal to the specified value. If this is not the case, the "T-sensor count error" is generated (see the "Protections - Temperature sensor count" section)
61 -
62 -== Improvements ==
63 -
64 -* new parameters that configure delays before and after the "Logic offline" error is generated (see the "Protections - Logic offline" section)
65 -* new CLI command "find-log" which finds a log file containing a specified timestamp
66 -
67 -== Fixes ==
68 -
69 -* resolving the issue of rebooting the device if formatting the SD card is activated
