these instead of calling via hal.port functions or accessing hal.port properties.
Improved the ioports API, updated core code to make use of it.
Flagged some calls and (part of) some stuctures as deprecated.
Added '$709' setting for second PWM spindle when available - PWM options.
Added properties to PWM spindles to allow "overdriving" PWM output when _RPM controls spindle enable signal is enabled with '$9' or '$709'.
Optimized Modbus CRC calculation, may fix issue with a compiler generating different code compared to most others. Ref. issue #723.
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.
Changed signature of vfs.on_mount() event.
Added grbl.on_cycle_start() event, fired on cycle start signal asserted or on cycle start real time command received.
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.
No longer copies spindle on delay from door setting ($392) to the new general setting ($340) on update from pre 20250103 builds.
Fixed missed code change when general spindle on delay was implemented causing the delay to be inserted on a simple RPM change with the S word.
Improved default serial port mapping when both MPG mode and keypad plugin are enabled to ensure the port is shared.
Delayed status report output on MPG mode change a few milliseconds to avoid awakening the ESP32 guru that sometimes reboots the controller.
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.
Added named parameters _probe_state and _toolsetter_state. Both return -1 if state is not available.
These may return incorrect values initially so use with care.
