I've just released this at [
github.com] (as usual, follow the link and press the Raw button to download it). Here is the change list:
* Bug fix: in version 1.09i (not earlier versions), the pause function sometimes used to hang while running the pause macro file.
* Don't wait for all moves to complete when executing a G92 command that just resets extruder positions. This affected the quality of prints that use absolute extruder moves, although relative extruder moves are recommended with RepRapFirmware.
* M574 endstop configuration now overrides M558 when determining whether or not to use the Z probe instead of a homing switch.
* Added XYZ parameters to M667 command to support CoreXZ etc. machines with paired axis ratios that are not 1:1.
* Minor change to step ISR to improve timings and service drives in round-robin order.
