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.

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.
NOTE: this is a relatively large change and may have introduced bugs and/or unintended side-effects. Please report any issues!
Added setting $519 for binding spindle encoder to given spindle in multi spindle configurations.
Added machine readable spindle enumeration report, $SPINDLESH.
Increased default value for setting $398 (number of planner blocs) from 35 to 100 for faster laser engraving.
NOTE: the $398 setting value will not change on an upgrade!
NOTE: STM32F103 builds for the 128K flash variants does not have enough free RAM and will keep 35 as the default value.
Increased allowed number of decimal places from 3 to 5 for $10x stepper step/mm settings. Ref. ioSender issue 346.
Added setting $650 for filing system options. Ref. issue 397.
Currently the following bits are available (depending on the configuration):
0 - Auto mount SD card on startup (1).
1 - Do not add littlefs files when listing the root directory (2).
Added build option for lathe UVW mode.
When enabled UVW words can be used to command relative moves for XYZ without switching to relative mode with G91.
NOTE: This permanently sets lathe mode and disables the $32 mode setting.
There are signature changes to some spindle, ioports enumeration and VFS filing system mount functions.
Added events to allow plugin code to handle tool table data, possibly stored on a SD card.
Some drivers will now only disable hard limits (if enabled) for axes that are homing, this includes max/min limit switches.
HAL entry points and core handlers/events has been added and some have changed signatures in order to better support kinematics implementations.
More work on delta kinematics: new and changed settings, some improved functionality. Still in progress.
