Release Notes

Released on 2026-07-25.

Highlights

• This release adds two new builtin hooks, deny-pattern and require-pattern,
  as native alternatives for pygrep use cases. deny-pattern fails when a
  configured pattern is found, while require-pattern ensures every selected
  file contains a match. By matching natively without spawning a Python
  subprocess, they run over 4x faster than pygrep in benchmarks. Note that
  they use Rust regex syntax, which does
  not support look-around features such as negative lookbehind.

• prek run now supports --glob <PATTERN> to run hooks on tracked files
  matching a glob. It can be repeated or combined with --files and
  --directory.

• Hook priorities now support reusable aliases:

  [priorities]
  checks = 10
  
  [[repos]]
  repo = "builtin"
  hooks = [
    { id = "check-json", priority = "checks" },
    { id = "check-yaml", priority = "checks" },
  ]

  This makes parallel scheduling easier to read and maintain.
