	9	+
	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

	25	+
	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

	50	+
	51	+== Fixes ==
	52	+
	53	+* check the HYG and Combilift confirmation flags only if the truck offline error is not set
	54	+* small internal fixes

	57	+
	58	+[[BMS_Main_2.1_v1.69.0.srec>>FileManager.BMS_Main_2\.1_v1\.69\.0\.srec]]
	59	+
	60	+== Features ==
	61	+
	62	+* new parameter for setting the condition for starting balancing: automatically (regardless of the command) or on the balancing request (see the "Cells - Cell balancing" section)
	63	+* new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Cells - Cell balancing" section)
	64	+* new assignment "Balancing request" for the discrete inputs (see the "Signals - Input signals" section)
	65	+* new Max-Min algorithm for calculating the final battery SOC in the "Cells - SOC estimation" section
	66	+* new algorithms "Automatic" and "On command" for the main contactor (see the "Cells - Main contactor" section)
	67	+* new assignment "Close Main contactor" for the discrete inputs to close the main contactor by a command
	68	+* new assignment "Close External 1" for the discrete inputs (see the "Signals - Input signals" section)
	69	+* new assignment "External 1" for the discrete outputs and relays (see the "Signals - Output signals" section). The "External 1" output is directly controlled by the "Close External 1" command.
	70	+* new "Precharge error" flag that is set when precharging cannot be completed
	71	+* new flags in the "Protections - Undervoltage protection" and "Protections - Overvoltage protection" sections which allow using the calculated open circuit cell voltage instead of the actual voltage to detect the "Undervoltage" and "Overvoltage" errors, respectively
	72	+* ability to check the "Ready to charge" and "Ready to discharge" signals to control the charging and discharging contactors (see the "Cells - Charging control" and "Cells - Discharging control" sections)
	73	+
	74	+== Improvements ==
	75	+
	76	+* ignoring the "Need acknowledge" flag when generating Modbus input register 0x2128 ("Error")
	77	+* explicit flags to enable the use of the charging current limit for fast and/or normal charging when using the CCS Fast charge controller (see the "External equipment - CCS Fast charge controller" section)
	78	+* improving resistance calculation
	79	+
	80	+== Fixes ==
	81	+
	82	+* resolving the issue where the "Need acknowledge" signal is not set if any of the device errors are not acknowledged in the error journal
	83	+* using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals
