# Technician tool v0.9 - changes

- Two files per system for technicians: `update_windows.bat` / `update_macos.command` (update) and
  `run_windows.bat` / `run_macos.command` (start).
- Update: checks Gitea for the newest release tag `vX.Y`, downloads only what changed (git), shows the list of
  changes, protects files edited by hand (asks first), connects a folder unpacked from a release zip on first
  run, installs git / uv when missing (asks first) and brings the Python libraries up to date.
- One shared Python environment for all versions: `KotaTechnicianTool/venv` (was `venv-0.x` per version).
- A developer copy on a branch is left alone by the update script (use `git pull`).
