10 +== Improvements ==
11 +
12 +* new parameter setting a delay before measuring battery current during precharge (see the "Cells - Discharging control" section)
13 +* new counter of retry attempts showing the communication problems with BMS Logic devices (see the "Logic/Cell - Overview" section)
14 +* new flag to keep the precharging contactor closed until the precharging process is finished (in this case the "Precharge error" will not occur; see the "Cells - Discharging control" section)
15 +* 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
16 +
17 +== Fixes ==
18 +
19 +* resolving the issue of not being able to send log files to a remove FTP server due to a change in the file name format (v1.70.0)
20 +* increased number of retries when sending commands to BMS Logic devices, which reduces the number of false offline event detections

26 +== Improvements ==
27 +
28 +* new assignments "Low SOC" and "High charging current" for relays
29 +
30 +== Fixes ==
31 +
32 +* 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)

37 +
38 +== Features ==
39 +
40 +* new parameters allowing to set different delays for battery discharge mode to detect the overcurrent error (see the "Protections - Overcurrent protection" section)
41 +* new flag that sets whether the BMS should wait for confirmation messages from the Combilift truck to start charging or not (see the "External equipment - Combilift truck" section)
42 +
43 +== Fixes ==
44 +
45 +* optimization of the logging process, minimizing the time to open the next log file if the current one is full
