10 -== Improvements ==
11 -
12 -* new flags that force the precharge process to finish if the battery current is negative (in case the battery will be charging) or positive (in case the battery will be discharging); see the "Cells - Charging control" and "Cells - Discharging control" sections
13 -* 30 second delay when remounting SD card after detecting mount error
14 -* new flag to prevent the "HYG offline" error from occurring if the "Charger connected" signal is set (see the "External equipment - HYG Class I-III truck" section)
15 -* 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 - HYG Class I-III truck" section)

21 -== Improvements ==
22 -
23 -* new parameter setting a delay before measuring battery current during precharge (see the "Cells - Discharging control" section)
24 -* new counter of retry attempts showing the communication problems with BMS Logic devices (see the "Logic/Cell - Overview" section)
25 -* 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)
26 -* 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
27 -
28 -== Fixes ==
29 -
30 -* 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)
31 -* increased number of retries when sending commands to BMS Logic devices, which reduces the number of false offline event detections

38 -
39 -* new assignments "Low SOC" and "High charging current" for relays
40 -
41 -== Fixes ==
42 -
43 -* 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)

50 -
51 -* new parameters allowing to set different delays for battery discharge mode to detect the overcurrent error (see the "Protections - Overcurrent protection" section)
52 -* 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)
53 -
54 -== Fixes ==
55 -
56 -* optimization of the logging process, minimizing the time to open the next log file if the current one is full
