Improved alarm handling, if a critical alarm is active when a non-critical alarm is raised the non-critical alarm will be delayed until after reset for the critical alarm.
Improved Modbus exception handling and added high level API call for creating and sending Modbus messages.
Added G65P7 inbuilt macro for interacting with Modbus devices from gcode. See the Wiki for details.
Parking mode improvements.
Removed requirement for external encoder for spindle sync if stepper spindle is enabled.
Improved handling of $680 stepper enable delay.
Added ADC/DAC resolution to $pinstate command, changed reported values to integer for ADC/DAC devices and float formatted for PWM devices.
Numeric settings can now be set via G65P1Q<n>S<value>, <n> is the setting number, <value> is the new value.
Changed alarm code for Modbus exceptions (communication errors) from 14 to 19.
Refactored MPG stream code to allow plugins to hook into MPG streams (via event handler).
Added _free memory system parameter, returns value in KBytes or -1 if not available from driver.
Changed basic stream data type from char to uint8_t, added HAL function and core API for releasing/closing UART streams.
Some minor bug fixes such as incorrect error code returned for unknown $-commands and temporary incorrect position reporting on in-flight G92 offset changes.
Added HAL support for setting serial stream format.
Added setting $681 for configuring Modbus RTU stream parity, available when the underlying driver supports format setting.
Added $MODBUSSTATS and $MODBUSSTATS=R commands, outputs communication statistics such as number of sent commands, retries etc.
$MODBUSSTATS=R clears the statistics after outputting it.
Ref. issue #753.
Added G30 as optional position for tool change.
Moved new tool change mode from PR#673 to $346 - Tool change options.
Moved Modbus RTU code from spindle plugin to the core.
Fixed bug in delayed task handler, might occasionally hang the controller.
