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.
