9 -
10 -== Features ==
11 -
12 -* compressing CLI responses for some commands to speed up data exchange over slow interfaces
13 -* ability to reset a device password using a signed token
14 -
15 -== Improvements ==
16 -
17 -* maintaining continuous current limits below peak current limits
18 -* ability to clear the "Precharge error" based on the clock (calendar) time (see the "Control - Precharge" section)
19 -* Unibat: new parameter that determines the duration of the reduction in current limits after the insulation fault is detected
20 -
21 -== Fixes ==
22 -
23 -* resolving the issue of incorrect SD card handling when the filesystem is corrupted

33 -= v3.9.0 =
34 -
35 -== Improvements ==
36 -
37 -* support for the second bootloader v3
38 -* ability to complete device initialization without waiting for voltage stabilization on the power switches (see the "Control - Initialization" section)
39 -* MQTT optimization
40 -* optimization of BMS WiFi v2, BMS GSM v1, and BMS GSM v2 drivers
41 -* new assignment "Close External 1" and "Close External 1" for the discrete inputs (see the "Signals - Input discrete signals - Assignments" section)
42 -* 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.
43 -* 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)
44 -* Unibat: ability to halve current limits when the insulation warning is detected (see the "External equipment - Unibat vehicle - General parameters" section)
45 -* 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)
46 -* Unibat: ability to delay emergency battery disconnection when the isolation alarm is detected (see the "External equipment - Unibat vehicle - General parameters" section)
47 -* Unibat: ability to linearly reduce current limits to zero when the isolation alarm is detected (see the "External equipment - Unibat vehicle - General parameters" section)
48 -* Unibat: use of Ohm/Volt units to define insulation warning and alarm thresholds (see the "External equipment - Unibat vehicle - Diagnostic parameters" section)

63 -
64 -* Unibat: charge current limit protection is disabled in charge mode only when the "Use continuous charge current limit" flag is set
65 -* Unibat: discharge current limit protection is enabled regardless of whether the battery is in discharge or charge mode
