- Main: Support DXF output (using ezdxf)
- Main: Better board outline detection. Currently a pile of messy heuristics
- Gcode: Remove eurorack assumptions by default (make it a flag)
- Gcode: Support different drilling cycles (e.g. simple feed, G83)
- GCode: support work coordinate offsets other than G53
- GCode: better inter-component toolpaths (approx travelling salesman solver)
- Gcode: relax (too conservative) entry drill size requirements for slotted holes
- Fix all the bugs
