The export scripts in bin/ target KiCad 10 (kicad-cli). export.sh runs from a board repository root (reads revision.txt) and writes gerber/: gerbers with zones refilled in-memory, drill, position CSV, netlist + BOM CSV (via hellen-one-kicad-bom-plugin.py), schematic PDF and VRML. The board file itself is not modified.
