9 +
10 +== Fixes ==
11 +
12 +* resolving the problem of device rebooting when sending data via FTP and MQTT protocols using the BMS GSM v2 cellular module
13 +
14 += v3.9.0 =
15 +
16 +== Improvements ==
17 +
18 +* support for the second bootloader v3
19 +* ability to complete device initialization without waiting for voltage stabilization on the power switches (see the "Control - Initialization" section)
20 +* MQTT optimization
21 +* optimization of BMS WiFi v2, BMS GSM v1, and BMS GSM v2 drivers
22 +* new assignment "Close External 1" and "Close External 1" for the discrete inputs (see the "Signals - Input discrete signals - Assignments" section)
23 +* new assignment "External 1" and "External 2" for the discrete outputs and power switches (see the "Signals - Output discrete signals - Assignments" and "Signals - Power switches - Assignments" sections). The "External 1" and "External 2" output is directly controlled by the "Close External 1" and "Close External 2" command.
24 +* 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)
25 +* Unibat: ability to halve current limits when the insulation warning is detected (see the "External equipment - Unibat vehicle - General parameters" section)
26 +* Unibat: ability to emergency disconnect the battery when the isolation alarm is detected in any operating mode (charge and discharge) (see the "External equipment - Unibat vehicle - General parameters" section)
27 +* Unibat: ability to delay emergency battery disconnection when the isolation alarm is detected (see the "External equipment - Unibat vehicle - General parameters" section)
28 +* Unibat: ability to linearly reduce current limits to zero when the isolation alarm is detected (see the "External equipment - Unibat vehicle - General parameters" section)
29 +* Unibat: use of Ohm/Volt units to define insulation warning and alarm thresholds (see the "External equipment - Unibat vehicle - Diagnostic parameters" section)
30 +
31 +== Fixes ==
32 +
33 +* corrected values ​​of the "Internal signals that cause events to be sent" parameter in the "Service - MQTT" section

38 +
39 +== Improvements ==
40 +
41 +* Unibat: preventing the reset of the HVBPITS and HVBPITR signals if the device shutdown was caused by the insulation fault
42 +
43 +== Fixes ==
44 +
45 +* Unibat: charge current limit protection is disabled in charge mode only when the "Use continuous charge current limit" flag is set
46 +* Unibat: discharge current limit protection is enabled regardless of whether the battery is in discharge or charge mode
