0.3.2

Release Notes

Released on 2026-02-06.

Highlights

prek.toml is here!

You can now use prek.toml as an alternative to .pre-commit-config.yaml for configuring prek. prek.toml mirrors the structure of .pre-commit-config.yaml, but TOML is less error-prone. Your existing .pre-commit-config.yaml will continue to work, but for new users and new projects, prek.toml may make more sense. If you want to switch, run prek util yaml-to-toml to convert YAML configs to prek.toml. See configuration docs for details.

For example, this config:
```
repos:
  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v6.0.0
    hooks:
      - id: check-yaml
```
Can be written as like this:

prek.toml

[[repos]]
repo = "https://github.com/pre-commit/pre-commit-hooks"
rev = "v6.0.0"
hooks = [ { id = "check-yaml" } ]

serde-yaml has been replaced with serde-saphyr

We replaced the long-deprecated serde-yaml crate with serde-saphyr for YAML parsing. It is written in safe Rust and has better error messages, performance, and security. This lets us provide precise location information for configuration parsing errors, which should make it easier to fix config issues.

For example, this invalid config:

repos:
  - repo: https://github.com/crate-ci/typos
    hooks:
      - id: typos

Before:

$ prek run
error: Failed to parse `.pre-commit-config.yaml`
  caused by: Invalid remote repo: missing field `rev`

Now:

$ prek run
error: Failed to parse `.pre-commit-config.yaml`
  caused by: error: line 2 column 5: missing field `rev` at line 2, column 5
  --> <input>:2:5
