v2.3.0

The new path-finding is faster but it also does more. For most designs you'll see a speed-up and some milling with lots less retracting. Only for very large designs the processing might slow down. Either way, you'll more than make up for it in time saved while milling.

Version 2.1.0

Lots of new features and fixes since 2.0.0, which was over a year ago. Some highlights:

• Improved performance around the parsing of gerber files. #288
• Path finding to allow the mill to search for ways to connect milling paths without lifting the tool, when its faster. #285
• --invert-gerbers flag so that you can mill out traces instead of milling around them, like if you want to attach a marker and draw on a transparency. #292
• All options explained in the Wiki.
• Draw gerber lines as lines, so you can attach a pen and draw your silk layer on to your PCB. #303
• Remove the old, non-vectorial surface. #309
• Switch from TravisCI to Github actions because it's faster. #375
• Clean up lots of errors and warnings and now build with pedantic warnings. #364
• Improve support for milling thermals. #400
• Add backtracking to improve milling speed. #418 #427
• Make milling paths that try to have fewer turns so that paths are straighter. #433
• Add "spikes" to fill in gaps when extra passes are requested. #439
• GEOS support. If you have libgeos installed, pcb2gcode will use it and it may fix problems in some cases. #443
