Release Notes

astral-sh/ruff (ruff)

v0.16.0

Compare Source

Released on 2026-07-23.

Check out the blog post for a migration
guide and overview of the changes!

Breaking changes

  • Ruff now enables a much larger set of rules by default (413, up from 59). See the blog post for
    more details and the new Default Rules page for a
    full listing of the enabled rules.

  • Ruff can now format Python code blocks in Markdown files and will do this by default. See the
    documentation for more details.

  • Ruff now supports ruff: ignore comments at the ends of lines, like noqa comments, or on the line preceding a diagnostic. For example, these both suppress an unused-import (F401) diagnostic:

    import math  # ruff: ignore[F401]

# ruff: ignore[F401]
import os

  • Fixes are now shown in check and format --check output:

    ❯ ruff format --check .
unformatted: File would be reformatted
 --> try.md:1:1
  |
1 | ```python
  - import   math
2 + import math
3 | ```
  |

1 file would be reformatted

    This example also shows off the Markdown formatting.

  • format --check now supports the same output formats as the linter, including the github and
    gitlab outputs for rendering annotations in CI:

    ❯ ruff format --check --output-format github .
::error title=ruff (unformatted),file=try.md,line=2,col=8,endLine=2,endColumn=10::try.md:2:8: unformatted: File would be reformatted

    See the CLI help or documentation for the
    full list of supported formats.

  • The filename, location, end_location, fix.edits[].location, and fix.edits[].end_location
    fields in the JSON output format may now be null rather than defaulting to the empty string and
    row 1, column 1, respectively.

Verifying GitHub Artifact Attestations

The artifacts in this release have attestations generated with GitHub Artifact Attestations. These can be verified by using the GitHub CLI:

gh attestation verify <file-path of downloaded artifact> --repo astral-sh/ruff

You can also download the attestation from GitHub and verify against that directly:

gh attestation verify <file-path of downloaded artifact> --bundle <file-path of downloaded attestation>
