Amp now lets a single runner provide Multiple Directory Serving instead of just the launch folder. You can point the runner at specific paths or enable Auto-Discover Git Repositories to automatically include every checkout within two levels. Directories can be added or removed while the runner is running, and the changes persist for the next start. Runners also feature a Self-Updating Runner that checks hourly and restarts with the new version, preserving its ID, flags, and served directories.
