Release Notes

This is a follow-up to release 0.10.0. The requires-python inference changes were unintentionally omitted from 0.10.0, and have been included here. This release also includes stabilization of the preview behavior for PGH004.

Breaking changes

• Changes to how the Python version is inferred when a target-version is not specified (#16319)

  In previous versions of Ruff, you could specify your Python version with:

  • The target-version option in a ruff.toml file or the [tool.ruff] section of a pyproject.toml file.
  • The project.requires-python field in a pyproject.toml file with a [tool.ruff] section.

  These options worked well in most cases, and are still recommended for fine control of the Python version. However, because of the way Ruff discovers config files, pyproject.toml files without a [tool.ruff] section would be ignored, including the requires-python setting. Ruff would then use the default Python version (3.9 as of this writing) instead, which is surprising when you've attempted to request another version.

  In v0.10, config discovery has been updated to address this issue:

  • If Ruff finds a ruff.toml file without a target-version, it will check
    for a pyproject.toml file in the same directory and respect its
    requires-python version, even if it does not contain a [tool.ruff]
    section.
  • If Ruff finds a user-level configuration, the requires-python field of the closest pyproject.toml in a parent directory will take precedence.
  • If there is no config file (ruff.tomlor pyproject.toml with a
    [tool.ruff] section) in the directory of the file being checked, Ruff will
    search for the closest pyproject.toml in the parent directories and use its
    requires-python setting.

Stabilization

The following behaviors have been stabilized:

• blanket-noqa (PGH004): Also detect blanked file-level noqa comments (and not just line level comments).

Preview features

• [syntax-errors] Tuple unpacking in for statement iterator clause before Python 3.9 (#16558)
