9 +
10 +== Improvements ==
11 +
12 +* new parameter for setting the type of temperature sensors 1 and 2 connected to the device (sensors connected to BMS Logic devices and to BMS Main 3 device may differ; see the "Signals - Temperature sensors" section)
13 +* new flags that force only positive and negative currents to be used to determine open circuit voltages to control the "Ready to charge" and "Ready to discharge" signals respectively
14 +* new parameter setting a delay before measuring battery current during precharge (see the "Control - Precharge" section)
15 +* new flag to keep the precharging contactor closed until the precharging process is finished (in this case the "Precharge error" will not occur except for the one caused by high power; see the "Control - Precharge" section)
16 +* new flag to prevent the "HYG offline" error from occurring if the "Charger connected" signal is set (see the "External equipment - Trucks and Vehicles - HYG Class I-III truck" section)
17 +* new flag that controls whether to wait for confirmation from the HYG truck or not, to allow the battery to be charged (see the "External equipment - Trucks and Vehicles - HYG Class I-III truck" section)
18 +* new flag that controls whether to wait for confirmation from the Combilift truck or not, to allow the battery to be charged (see the "External equipment - Trucks and Vehicles - Combilift truck" section)
19 +* 30 second delay when remounting SD card after detecting mount error
20 +* new counter of retry attempts showing the communication problems with BMS Logic devices (see the "Battery" section)
21 +
22 +== Fixes ==
23 +
24 +* increased number of retries when sending commands to BMS Logic devices, which reduces the number of false offline event detections

30 +== Improvements ==
31 +
32 +* new parameter for setting the type of network to which the BMS GSM communication module connects (see the "Connectivity - Cellular" section)
33 +
34 +== Fixes ==
35 +
36 +* resolving the issue of ill-considered reduction of the battery SOC level when the cell voltage is close to the level corresponding to SOC=0% (due to the flow of a large discharge current leading to the high voltage drop on the cells)

42 +== Improvements ==
43 +
44 +* increasing the accuracy of resistance calculations
45 +* new parameters for battery manufacturers: manufacturer name, hardware ID, software ID, configuration description, production date (see the "Service - User settings" section)
