Release Notes

Released on 2026-08-27.

Highlights

Choose where hook toolchains come from

language_version now accepts a source preference alongside the version
request, letting you control where prek looks for a compatible toolchain when
it creates a hook environment. Use managed (the default) or system to choose
which source prek tries first while still allowing fallback and downloads. Use
only-managed or only-system to require one source.

For example, this local Ruff hook requires a Python 3.12 toolchain managed by
prek:

repos:
  - repo: local
    hooks:
      - id: ruff
        name: ruff
        language: python
        entry: ruff check
        additional_dependencies: [ruff]
        language_version:
          request: "3.12"
          preference: only-managed

With only-managed, prek reuses a compatible toolchain from its managed store
or downloads one when needed. It never falls back to Python from PATH, an OS
package manager, or a version manager, so toolchain selection does not depend on
the developer or CI machine's external environment.

Existing scalar values such as language_version: "3.12" continue to work. See
toolchain management and language_version
for the full source-selection behavior. (#2613)

Breaking changes

The breaking changes in this release are mostly small cleanups, and most users should not be affected.

  • Group names can no longer start with @. This prefix is now reserved for special group selectors such as the new @​ungrouped selector. (#2617)
  • PREK_MAX_CONCURRENCY has been removed. Use PREK_CONCURRENT_HOOKS and PREK_CONCURRENT_BATCHES to control hook and per-hook batch concurrency separately. (#2620)
  • The top-level prek init-template-dir command… (truncated)

### v0.5.0

## Release Notes

Released on 2026-08-27.

### Highlights

#### Choose where hook toolchains come from

`language_version` now accepts a source `preference` alongside the version
`request`, letting you control where prek looks for a compatible toolchain when
it creates a hook environment. Use `managed` (the default) or `system` to choose
which source prek tries first while still allowing fallback and downloads. Use
`only-managed` or `only-system` to require one source.

For example, this local Ruff hook requires a Python 3.12 toolchain managed by
prek:

```yaml
repos:
  - repo: local
    hooks:
      - id: ruff
        name: ruff
        language: python
        entry: ruff check
        additional_dependencies: [ruff]
        language_version:
          request: "3.12"
          preference: only-managed
```

With `only-managed`, prek reuses a compatible toolchain from its managed store
or downloads one when needed. It never falls back to Python from `PATH`, an OS
package manager, or a version manager, so toolchain selection does not depend on
the developer or CI machine's external environment.

Existing scalar values such as `language_version: "3.12"` continue to work. See
[toolchain management and `language_version`](https://prek.j178.dev/0.5.0/languages/#toolchain-management-and-language_version)
for the full source-selection behavior. ([#2613](j178/prek#2613))

### Breaking changes

- Group names can no longer start with `@`. This prefix is now reserved for special group selectors such as the new `@​ungrouped` selector. ([#2617](j178/prek#2617))
- `PREK_MAX_CONCURRENCY` has been removed. Use `PREK_CONCURRENT_HOOKS` and `PREK_CONCURRENT_BATCHES` to control hook and per-hook batch concurrency separately. ([#2620](j178/prek#2620))
