9 +
10 +== Features ==
11 +
12 +* compatibility with the BMS Main 2R device; from this release onwards, the BMS Main 2R firmware version will be the same as the BMS Main 3 firmware version
13 +* compressing CLI responses for some commands to speed up data exchange over slow interfaces
14 +* ability to reset a device password using a signed token
15 +
16 +== Improvements ==
17 +
18 +* calculating the remaining time until the battery is completely discharged or fully charged
19 +* detection of missing cells not only by number but also by their position (see the "Protection - Cell count" section)
20 +* detection of missing temperature sensors not only by number but also by their position (see the "Protection - Temperature sensor count" section)
21 +* optimization in the MQTT library
22 +
23 +== Fixes ==
24 +
25 +* resolving the issue of incorrect SD card handling when the filesystem is corrupted

10 -new flag that forces the "Ready to discharge" signal to clear when the "Low SOC" signal is generated (see the "Control - Discharging status" section)
11 -new input signal "Close External 2" which generates the new internal signal "External 2" which can be assigned to a discrete output or a power switch (see the "Signals - Input discrete signals - Assignments", "Signals - Output discrete signals - Assignments", and "Signals - Power switches - Assignments" sections)
12 -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)

16 -new flags for generating the "Ready to charge" and "Ready to discharge" signals using the actual cell voltage instead of the calculated open circuit voltage (see the "Control - Charging status" and "Control - Discharging status" sections)
17 -new flag the forces the device to wait for the "Charge request" and "Discharge request" signals to clear before reconnecting power contactors if the connection to the BMS Main X device is temporarily lost (see the "External equipment - BMS - Main X" section)
18 -new CAN bus speed is not applied until the device is rebooted
19 -logging the following new parameters: "Keyrun", "ChargeOn"
