	10	+== Features ==
	11	+
	12	+* new flags that allow to interrupt (shorten) the module balancing stage if all battery modules are already joined (see the "Control - Charge", "Control - Discharge", "Control - Charge/Discharge" sections)

	14	+* new parameter for setting the type of network to which the BMS GSM communication module connects (see the "Connectivity - Cellular" section)
	15	+* new flag that controls whether to use open circuit voltage or actual voltage when determining the voltage unbalance error (see the "Protections - Voltage unbalance (in any state)" section)
	16	+* new regulator that maintains battery current limiting to ensure that actual module currents do not exceed their current limits (see the "Control - Charge", "Control - Discharge", "Control - Charge/Discharge" sections)
	17	+* ability to select the battery module errors that cause the battery critical error (see the "Protections - Critical error" section)

	21	+
	22	+* dynamic calculation of data transfer schedule for optimal communication with a large number of battery modules
	23	+* ability to complete device initialization after the set timeout has expired and the minimum number of modules has been detected (see the "Control - Initialization" section)
	24	+* 30 second delay when remounting SD card after detecting mount error
	25	+* saving the number of joined modules in log files

	35	+== Features ==
	36	+
	37	+* new algorithm in the Charging/Discharging controller that allow to control the Charging/Discharging contactor independently from the Charging and Discharging signals (see the "Control - Charge/Discharge" section). The new "Independent" algorithm is preferred in the battery systems with one contactor
	38	+* new "Need acknowledge" warning signal that is set when a new record is created in the errors journal. The signal can be cleared in the "Service - Errors journal" section
	39	+* new Max-Min algorithm for calculating the final battery SOC in the "Control - Calculation" section
	40	+* improved control of the precharging contactor, which can precharge capacitive load using multiple attempts and detect high power dissipated in the precharge resistor (see the "Control - Precharge" section)
	41	+* ability to exclude errors from being saved in the error journal (see the "Service - Errors journal" section)
	42	+* ability to restart the device according to a specified schedule at the moment when the battery system is preparing to charge
	43	+* new error "High contactor temperature" that can be used to open the specified contactor to prevent it from overheating (see the "Protections - High contactor temperature" section)
	44	+* new internal signal "Coolant pump" that can be assigned to a relay or discrete output (for signal settings, see the "Control - Coolant pump" section)
	45	+* new flags indicating the readiness of battery modules to join for charging and discharging (see the "Modules" section)
	46	+* new flag to set the "Voltage unbalance" errors for battery modules that are not ready to charge or discharge (see the "Protections - Voltage unbalance (in any state)" section)
	47	+* initial support for Pylontech inverters
	48	+* extension of the CANopen dictionary to provide additional information for the BMS Display (device serial number, battery serial number, battery address, Wi-Fi and LAN addresses, SOH, capacity, etc.)
	49	+
	50	+== Improvements ==
	51	+
	52	+* ability to finish device initialization even if the number of battery modules found is less than the number of modules enabled (see the "Control - Modules" section)
	53	+* placing the device input signals to the "Battery" section and adding raw discrete inputs to the "Signals" section
	54	+
	55	+== Fixes ==
	56	+
	57	+* resolving the issue of ignoring the minimum number of battery modules allowed to join located in the "Control - Discharge" section
	58	+* resolving the issue of joining battery modules the number of which must be greater than or equal to the minimum value specified in the settings
	59	+* small internal fixes
