0.4.4

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:

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]

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.
