6 += v3.10.1 =
7 +
8 +[[BMS_Main_3X_v3.10.1.bin>>FileManager.BMS_Main_3X_v3\.10\.1\.bin]]
9 +
10 +== Improvements ==
11 +
12 +* support for multiple clients expecting compressed CLI responses
13 +* deleting old log files when the SD card is full (see the corresponding flag in the "Service - SD card" section)

16 +
17 +[[BMS_Main_3X_v3.10.0.bin>>FileManager.BMS_Main_3X_v3\.10\.0\.bin]]
18 +
19 +== Features ==
20 +
21 +* compressing CLI responses for some commands to speed up data exchange over slow interfaces
22 +* ability to reset a device password using a signed token
23 +
24 +== Improvements ==
25 +
26 +* maintaining continuous current limits below peak current limits
27 +* ability to clear the "Precharge error" based on the clock (calendar) time (see the "Control - Precharge" section)
28 +* Unibat: new parameter that determines the duration of the reduction in current limits after the insulation fault is detected
29 +
30 +== Fixes ==
31 +
32 +* resolving the issue of incorrect SD card handling when the filesystem is corrupted

37 +
38 +== Fixes ==
39 +
40 +* resolving the problem of device rebooting when sending data via FTP and MQTT protocols using the BMS GSM v2 cellular module
41 +
42 += v3.9.0 =
43 +
44 +== Improvements ==
45 +
46 +* support for the second bootloader v3
47 +* ability to complete device initialization without waiting for voltage stabilization on the power switches (see the "Control - Initialization" section)
48 +* MQTT optimization
49 +* optimization of BMS WiFi v2, BMS GSM v1, and BMS GSM v2 drivers
50 +* new assignment "Close External 1" and "Close External 1" for the discrete inputs (see the "Signals - Input discrete signals - Assignments" section)
51 +* 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.
52 +* 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)
53 +* Unibat: ability to halve current limits when the insulation warning is detected (see the "External equipment - Unibat vehicle - General parameters" section)
54 +* 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)
55 +* Unibat: ability to delay emergency battery disconnection when the isolation alarm is detected (see the "External equipment - Unibat vehicle - General parameters" section)
56 +* Unibat: ability to linearly reduce current limits to zero when the isolation alarm is detected (see the "External equipment - Unibat vehicle - General parameters" section)
57 +* Unibat: use of Ohm/Volt units to define insulation warning and alarm thresholds (see the "External equipment - Unibat vehicle - Diagnostic parameters" section)
58 +
59 +== Fixes ==
60 +
61 +* corrected values ​​of the "Internal signals that cause events to be sent" parameter in the "Service - MQTT" section
