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. Note that this is primarily an expansion, but 18 of the more opinionated pycodestyle (E) and pyflakes (F) rules have been removed from the default set: E401, E402, E701, E702, E703, E711, E712, E713, E714, E721, E731, E741, E742, E743, F403, F405, F406, and F722.

• 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.

🔁 AI review rerun (requested by @igerber)

Head SHA: 400b6153e7a2dfc3e3e34d217a086fd1e78e4fb1

---

Overall Assessment: ✅ Looks good

Executive Summary

• No estimator, statistical, or methodology behavior changed.
• Ruff pins are synchronized between CI and development dependencies.
• Explicit Ruff rule selection avoids the 0.16 default-rule expansion.
• No P0–P3 findings identified.

Methodology

No findings. The PR changes development tooling only; no registry method or paper requires cross-checking.

Code Quality

No findings. Pins match at .github/workflows/lint.yml:L42 and pyproject.toml:L68.

Performance

No findings. Runtime performance is unaffected.

Maintainability

No findings. Explicit rules at pyproject.toml:L131-L137 preserve lint behavior across the upgrade.

Tech Debt

No findings. No new limitation or deferred work is introduced.

Security

No findings. Ruff remains an exact development-only pin.

Documentation/Tests

No findings. CHANGELOG.md:L59-L64 documents the upgrade and compatibility rationale. Existing lint CI directly exercises the updated version. Ruff was unavailable in the review environment, so the clean-lint claim was not independently rerun.

Overall Assessment: ✅ Looks good

Executive Summary

• No estimator, inference, variance, weighting, assumptions, or defaults changed.
• Ruff 0.16.0 pins match across CI and development dependencies.
• Explicit rule selection preserves the prior lint scope despite Ruff’s expanded defaults.
• No P0–P3 findings; the previous clean review remains valid.
• Ruff, Black, and pytest were unavailable locally, so checks could not be independently rerun.

Methodology

No findings.

• Severity: None
• Impact: The PR only changes development tooling; no Methodology Registry entry or cited estimator paper is affected.
• Concrete fix: None.

Code Quality

No findings.

• Severity: None
• Impact: CI and development pins agree at .github/workflows/lint.yml:L41-L44 and pyproject.toml:L63-L69.
• Concrete fix: None.

Performance

No findings.

• Severity: None
• Impact: Runtime library performance is unaffected.
• Concrete fix: None.

Maintainability

No findings.

• Severity: None
• Impact: The explicit selector at pyproject.toml:L135-L137 protects the repository from Ruff’s expanded defaults, with rationale documented at CONTRIBUTING.md:L22-L27.
• Concrete fix: None.

Tech Debt

No findings.

• Severity: None
• Impact: No limitation or deferred work is introduced.
• Concrete fix: None.

Security

No findings.

• Severity: None
• Impact: Ruff remains an exact, development-only dependency.
• Concrete fix: None.

Documentation/Tests

No findings.

• Severity: None
• Impact: CHANGELOG.md:L59-L69 documents the upgrade and compatibility rationale. Existing pin-sync coverage verifies the CI/dev dependency contract.
• Concrete fix: None.
