+      --zero_xy, -zxy       On completion, move straight up to
+                            rapid_safety_height, then across to X0 Y0.
+      --zero_z, -zz         On completion, move down to Z0 (done after zero_xy, if
+                            set).
+      --rapid_safety_height RAPID_SAFETY_HEIGHT, -rsh RAPID_SAFETY_HEIGHT
+                            Z value to move to before traversing workpiece (if not
+                            set, max value will be attempted).
+      --spindle_off, -so    On completion, turn spindle off.
+
+
+Added ability to remove all codes & parameters that cannot be parsed.
+
+      --rm_invalid_modal, -rmim
+                            Simply remove everything that isn't understood. Use
+                            with caution.
+
+**Library Improvements**
+
+* `Machine.abs2work(<Position>)` and `Machine.work2abs(<Position>)` position
+  converters, apply machine's offset to the given position without effecting
+  machine's current position.
+* `Machine.clean_block(<Block>)` removes content from a block that's not parsable (use with caution)
+* `Machine.ignore_invalid_modal` bool class parameter, if set, will continue on merrily while ignoring
+  anything not parsable (similarly to `clean_block`)
