Updates prek from 0.4.11 to 0.5.0

Release notes

Sourced from prek's releases.

0.5.0

Release Notes

Released on 2026-08-27.

Highlights

Choose where hook toolchains come from

language_version now accepts a source preference alongside the version request, letting you control where prek looks for a compatible toolchain when it creates a hook environment. Use managed (the default) or system to choose which source prek tries first while still allowing fallback and downloads. Use only-managed or only-system to require one source.

For example, this local Ruff hook requires a Python 3.12 toolchain managed by prek:

repos:
  - repo: local
    hooks:
      - id: ruff
        name: ruff
        language: python
        entry: ruff check
        additional_dependencies: [ruff]
        language_version:
          request: "3.12"
          preference: only-managed

With only-managed, prek reuses a compatible toolchain from its managed store or downloads one when needed. It never falls back to Python from PATH, an OS package manager, or a version manager, so toolchain selection does not depend on the developer or CI machine's external environment.

Existing scalar values such as language_version: "3.12" continue to work. See toolchain management and language_version for the full source-selection behavior. (#2613)

Breaking changes

The breaking changes in this release are mostly small cleanups, and most users should not be affected.

• Group names can no longer start with @. This prefix is now reserved for special group selectors such as the new @ungrouped selector. (#2617)
• PREK_MAX_CONCURRENCY has been removed. Use PREK_CONCURRENT_HOOKS and PREK_CONCURRENT_BATCHES to control hook and per-hook batch concurrency separately. (#2620)
• The top-level prek init-template-dir command has been removed. Use prek util init-template-dir, or prek init-templatedir for drop-in compatibility with pre-commit. (#2623)
• prek auto-update has been removed. Use prek update, or prek autoupdate for drop-in compatibility with pre-commit. (#2619)
