# tuna-cli v0.40.0

November 6, 2026

> **Check your inspector settings.** In the Docker image, the inspector of `tuna http`, `tuna 1c`, and `tuna kubernetes` is now off; turn it on with `TUNA_INSPECT=true`. The `inspectAddr` key in `tuna.yml` is no longer read, and a busy `--inspect-port` stops the tunnel. See the [inspector](https://tuna.am/en/docs/tunnels/inspect.md#port) page.
