Fix for parking motion using `$32` laser mode setting when it should use the current spindle mode.
For developers: changed signature of `hal.stream.on_linestate_changed()` to include stream properties.
Added P-word option to G38.x probe commands, use to temporarily switch the probe input when multiple probes are available.
Fixed PWM spindle ramping, did not hit the target RPM.
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.
Added experimental support for G66 (modal macro call) and G67 (end modal macro call).
Made axis letter to axis/motor assignment for axes ABCUVW freely changeable at compile time.
Fix for some G65 arguments being incorrectly validated for normal use (sign, range).
Added repeat support to G65 macro call via the optional L parameter word.
Changed default setting for ABC-axes to rotary.
Changed defaults for jerk settings to 10x acceleration settings.
Disabled jerk for jog, probe and spindle synchronized motion.
Added _active_probe system parameter, returns -1 if no probe inputs available.
Minor bug fix, G5.1 and G33.1 motion commands were not coverted to the correct string equivalent in $G output.
Added tool name, pocket number and some lathe specific data fields to the $# tool output when available from the tool table.
If name is available it will be output as a push message on M6 if there is no message in the same block.
Added support for directory up, .., to VFS.
Added new option to $650 - File systems options to enable hierarchical listing of files and directories via $F and $F+ commands.
Moved probe signal handling from drivers to the core, improved handling of probe disconnected signal.
NOTE: The changes above are quite large, please verify probe operation after installation.
Added system parameter _tool_table_size, 0 if a tool table is not enabled.
Removed dependency on safety door input for parking settings: $41, $42, $56-$59, $392 and $393.
Removed strict dependency on spindle encoder input for spindle synced motion,
allows the use of the stepper spindle which has an implicit encoder.
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.
Named system parameters _current_pocket and _selected_pocket updated to return the correct values.
Moved handling of keeping last tool number over reboot from template plugin to the core.
Added named system parameters _homed_state and _homed_axes.
Fix for failure to claim auxiliary ports in some configurations.
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.
Added HAL parameter for minimum step pulse length set by driver, used for validation of $0 setting.
Changed HAL API signature for outputting step pulses, optimized to allow drivers to only change direction outputs when there is an actual direction change.
Improved handling of overrides at end of program when all motion is buffered. Possible fix for issue #714.
Some optimizations to allow higher step rates.
Added setting $676 with flags to control soft reset actions. See the changelog for details.
Workaround for Microsoft C adding a non-standard reserved keyword...
Improved handling of stop realtime command (0x19) for faster motion halt without losing position.
Optimized RAM usage. Fixed regression related to losing current coordinate system and tool offset over a stop.
new HAL entry point for querying/resetting driver status.
Added driver capability flags and settings, $742 - $745, for enabling and inverting motor warning and fault input signals (per axis).
Improved jerk acceleration. Ref. PR #660.
Sub name matches filename with extension .macro.
Added core event for handling special gcode comments used by expressions and flow control: DEBUG, PRINT and ABORT.
Added overrideable default $-setting values for second PWM spindle to grbl/config.c.
(probe input pullup disable) settings from boolean to bitfield when driver support is available.
Added a few default values for settings in config.h, overridable from the compiler command line.
Added core support for per axis pulloff distance, needs plugin for configuring them.
Added HAL flags for disabling settings for MCU input pins pullup disable, may be set by
drivers/boards that has buffered (optocoupled) inputs that is not possible to change.
Added named parameters for getting absolute (G53) position: _abs_x, abs_y, ...
Available when expression support is enabled.
Changed stepper enable HAL signature to allow current reduction when idle.
Added reference id to spindle registration in order to allow configuring default spindle, and possibly additional spindles, at compile time.
Added setting $358 to enable experimental functionality for fast rotary 'rewind' to stored G28 position.
Return move should complete in half a rotation or less.
For developers: added option to redirect debug via driver provided function when DEBUGOUT is set to -1 in config.h. Ref. issue #545.
Added definitions for up to four additional digital aux I/O ports.
Added real time report of selected spindle in multi spindle configurations. Reported on changes only.
Removed limits override input invert config, for safety reasons it is always active low.
Added HAL entry points for second RGB channel, renamed first from hal.rgb to hal.rgb0.
Added option to setting $22 to force use of limit switches for homing when homing inputs are available in the driver/board combo.
Improved handling of aux I/O pins when claimed for core functions.
Added flag to $9 for disabling laser mode capability for primary PWM spindle. Allows leaving laser mode enabled when a secondary PWM spindle is available and this is used to control a laser.
Added some generic setting definitions for stepper drivers, currently used by the motors plugin.
Implemented handling of single block, block delete and optional stop disable control signal events.
Added help for $S (single block), $B (block delete) and $O (optional stop disable) commands.
Added optional HAL entry point for outputting WRGB values to lights such as neopixels.
Improved $-commands registration to make it easier to add help text.
