astral-sh/ruff (ruff)
v0.16.0
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. 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, andF722. -
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: ignorecomments at the ends of lines, likenoqacomments, or on the line preceding a diagnostic. For example, these both suppress anunused-import(F401) diagnostic:import math # ruff: ignore[F401] # ruff: ignore[F401] import os -
Fixes are now shown in
checkandformat --checkoutput:❯ ruff format --check . unformatted: File would be reformatted --> try.md:1:1 | 1 | ```python - import math 2 + import math 3 | ``` | 1 file would be reformattedThis example also shows off the Markdown formatting.
-
format --checknow supports the same output formats as the linter, including thegithubandgitlaboutputs 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 reformattedSee the CLI help or documentation for the full list of supported formats.
-
The
filename,location,end_location,fix.edits[].location, andfix.edits[].end_locationfields in the JSON output format may now benullrather than defaulting to the empty string and row 1, column 1, respectively.
Stabilization
The following rules have been stabilized and are no longer in preview:
airflow3-incompatible-function-signature(AIR303)missing-copyright-notice(CPY001)unnecessary-from-float(FURB164)sorted-min-max(FURB192)implicit-string-concatenation-in-collection-literal(ISC004)log-exception-outside-except-handler(LOG004)invalid-bool-return-type(PLE0304)too-many-positional-arguments(PLR0917)stop-iteration-return(PLR1708)none-not-at-end-of-union(RUF036)access-annotations-from-class-dict(RUF063)duplicate-entry-in-dunder-all(RUF068)
The following behaviors have been stabilized:
blind-except(BLE001) is now suppressed when the exception is logged vialoggingmethods other thancritical,errorandexception.future-required-type-annotation(FA102) now checks for additional PEP 585-compatible APIs, such as those fromcollections.abc.f-string-in-get-text-func-call(INT001),format-in-get-text-func-call(INT002), andprintf-in-get-text-func-call(INT003) now check for additional common ways of using thegettextmodule, such as assigning it tobuiltins._.suspicious-url-open-usage(S310) now resolves local string literal bindings to avoid more false positives.snmp-insecure-version(S508) andsnmp-weak-cryptography(S509) now support the recommended API from newer versions of PySNMP.typing-text-str-alias(UP019) now recognizestyping_extensions.Textin addition totyping.Text.

Expand the default rule set (#23385)
In preview, Ruff now enables a significantly expanded default rule set of 412 rules, up from the stable default set of 59 rules. The new rules are mostly a superset of the stable defaults, with the exception of these rules, which are removed from the preview defaults:
multiple-imports-on-one-line(E401)module-import-not-at-top-of-file(E402)module-import-not-at-top-of-file(E701)multiple-statements-on-one-line-semicolon(E702)useless-semicolon(E703)none-comparison(E711)true-false-comparison(E712)not-in-test(E713)not-is-test(E714)type-comparison(E721)lambda-assignment(E731)ambiguous-variable-name(E741)ambiguous-class-name(E742)ambiguous-function-name(E743)undefined-local-with-import-star(F403)undefined-local-with-import-star-usage(F405)undefined-local-with-nested-import-star-usage(F406)forward-annotation-syntax-error(F722)
If you use preview and prefer the old defaults, you can restore them with configuration like:
# ruff.toml [lint] select = ["E4", "E7", "E9", "F"] # pyproject.toml [tool.ruff.lint] select = ["E4", "E7", "E9", "F"]If you do give them a try, feel free to share your feedback in the GitHub discussion!
