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.
Fixed handling of NVS buffer allocation, size was not increased as expected when physical NVS is capable of holding more than 2 Kbytes.
This could lead to POS failure or plugins not initializing when a large tool table is configured.
Added lightweight JSON serializer outputting directly to file.
Fix for event handler sometimes called too early. Ref. issue #818.
For developers: added optional device filing system that can redirect file read/write to serial streams.
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.
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.
(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.
Fixed incorrect handling of G65 call parameters, axis words had offsets added. Ref. issue #594.
Refactored handling of multiple spindles. There are still some limitations but should work better now. Disabled override delays for now, needs investigation. Ref. issue #598.
NOTE: Please report any erratic behaviour after installing this version since it is a rather major change.
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 experimental support of LinuxCNC style subroutines.
Available for gcode run from local filesystem such as on a SD card or in littlefs.
Improved handling of G92 when G92 offset is changed while motion is ongoing. Ref. issue #241.
Fix for issue #521, crash when running G65 macro on ESP32.
"Hardened" stream switching code, likely fix for discussion #456.
Fixed incorrect reporting of feed rate modes in $G response.
Added some ioPorts call wrappers, full support for reconfiguring output auxillary pins for PWM output.
New/modified core entry points for soft limit checking.
More delta robot tuning, added setting warning in $DELTA output if some settings are inconsistent such as steps/rad, acceleration etc.
Fix for issue #361, HOME status is not reported or reported late when auto reporting is enabled with setting $481.
