### Highlights

🚀 This release introduces priority-based parallel hook execution: prek can run multiple hooks in parallel when they share the same `priority`, which can be a huge speed-up for many configs. See configuration docs for [`priority`](https://prek.j178.dev/configuration/#priority).

- Implement `priority` based parallel execution ([#1232](https://github.com/j178/prek/pull/1232))

### Bug fixes

- Fix `check-executable-have-shebangs` "command line too long" error on Windows ([#1236](https://github.com/j178/prek/pull/1236))

### Documentation

- Add FastAPI to the list of projects using prek ([#1241](https://github.com/j178/prek/pull/1241))
- Document hook_types flag and default_install_hook_types behavior ([#1225](https://github.com/j178/prek/pull/1225))
- Improve documentation for `priority` ([#1245](https://github.com/j178/prek/pull/1245))
