Release Notes

Released on 2026-08-10.

Highlights

Manage hook tools with mise

The new language: mise support lets hooks install tools using
mise in an isolated environment:

repos:
  - repo: local
    hooks:
      - id: golangci-lint
        name: golangci-lint
        language: mise
        additional_dependencies: ["aqua:golangci/golangci-lint@2"]
        entry: golangci-lint run --fast-only ./...
        pass_filenames: false

Run commands in hook environments

The new prek exec subcommand can run an explicit command in a configured
hook's prepared environment. For example, the hook above makes its managed
binary available to this command:

$ prek exec golangci-lint -- golangci-lint --version
