      "COMMAND... (required): Command to run in the image; here `echo \"works with unknown flavors\"`.",
      "Prerequisite: The machine must be logged in. Jobs require a positive credit balance.",
      "`JobHardware` is now its own enum, independent of `SpaceHardware`.",
      "The former `JobHardware` dataclass return type of `list_jobs_hardware()` is renamed `JobHardwareInfo`.",
      "A daily CI workflow syncs both enums from the live Hub API and opens a bot PR when something changes.",
      "Docs conflict: The CLI reference page lists `--flavor` as a fixed set of choices, while the v1.17.0 release note says the flag accepts any string. The release note describes the v1.17.0 behavior; the CLI reference page does not document that change."
