Release v0.0.276 · astral-sh/ruff

See the release blog post for more, including detailed descriptions of any newly added rules.

What's Changed

Highlights include: experimental support for linting Jupyter Notebooks.

To opt-in to linting Jupyter Notebook files, add the *.ipynb pattern to your include
setting, like so:

[tool.ruff]
# Allow Ruff to discover `*.ipynb` files.
include = ["*.py", "*.pyi", "**/pyproject.toml", "*.ipynb"]

This will prompt Ruff to discover Jupyter Notebook files in any specified directories, and lint them
accordingly.

Jupyter Notebook support is currently opt-in and experimental. We'd love your help testing it out.
