# Supported buf CLI versions

## Minimum tested version

Use buf CLI v1.67.0 or later against protos.rip. The registry implements the bufbuild/registry-proto v1 services the buf CLI calls — module, label, commit, upload, download, and graph — so older CLIs that pre-date those services will not work. Confirm your local version with `buf --version`.

```bash
buf --version
```

## Last tested

v1.67.0 (April 2026) is the most recent version we’ve validated end-to-end. Newer minor versions are expected to work; report regressions you hit so the matrix can be refreshed.

## Posture on CLI changes

The buf CLI ships frequently, and we don’t test every release before it lands. When a CLI release adds a new RPC dependency that protos.rip hasn’t implemented yet, the affected command surfaces an `Unimplemented` error from protos.rip and the rest of the CLI continues to work. Planned-but-not-yet-implemented services land via dashboard or admin RPCs first, then surface to the CLI when client support is published — see [buf CLI command coverage](/docs/reference/buf-cli-command-coverage) for current status.
