## Release Notes

Released on 2026-06-04.

### ✨  Highlights

0.4.4 makes `prek run` easier to watch and easier to slice.

Hook stream output now shows a small live preview under the running hook in the
progress UI. Long-running hooks no longer look stuck while they are producing
logs, and failed hooks are easier to diagnose because recent output is already
visible before the final result.

The new group selector lets a single config support different workflows. Tag
hooks with `groups`, then select or exclude those groups at run time:

```yaml
repos:
  - repo: local
    hooks:
      - id: format
        name: Format Python
        language: system
        entry: ruff format
        groups: [format, ci]

      - id: lint
        name: Lint Python
        language: system
        entry: ruff check
        groups: [lint, ci]
```

```bash
prek run --all-files --group ci
prek run --all-files --no-group format
```

This is useful when local development, CI, slow validation, or project-specific
checks need different hook sets without splitting the config.
