0.4.2

Release Notes

Released on 2026-05-26.

Highlights

0.4.2 is mainly about making prek run faster in large repos.

prek now does less git diff work. After hooks run, prek uses diff checks to detect files changed by hooks. If a hook modifies files, prek marks that hook as failed. That is important, but full diff snapshots can be slow in big repos, especially when they happen after every hook group.

We skip the expensive diff path in two common cases: built-in hooks that prek knows are read-only, and clean worktrees where a cheap dirty check is enough unless a hook actually changes files. In the right large-repo workload, skipping that work can make runs up to 10x faster.

Workspace mode is faster too. Hooks have historically been too serial. Priority-based concurrency helped, but it required users to choose good priority values. Now sibling projects at the same workspace depth run in parallel automatically. Their files do not overlap, so this is safe and needs no extra config. For multi-project workspaces, this can dramatically reduce total hook time.

Sponsorship

If prek saves time for you or your team, please consider sponsoring the project on GitHub Sponsors. It helps keep new features, performance work, and maintenance moving.
