 # Changes
 
+20191003: The move_to_previous option in [safe_z_homing] now defaults
+to False.  (It was effectively False prior to 20190918.)
+
 20190918: The zhop option in [safe_z_homing] is always re-applied
 after Z axis homing completed. This might need users to update custom
 scripts based on this module.
