v0.17.0Compare Source
Released on 2026-10-09.
The executables in our macOS and Windows release archives and
ruffwheels are now code-signed.macOS executables are signed with an Apple Developer ID certificate and notarized by Apple. Windows
executables have timestamped Authenticode signatures from Azure Artifact Signing. This enables
verification of the release publisher and binary integrity, supports publisher-based allowlisting,
and should reduce security warnings and antivirus false positives.
Breaking changes
Update the default and latest Python versions for 3.15 (#28792)
Ruff now defaults to Python 3.11 instead of 3.10 when no Python version is configured through
target-versionorrequires-python. Whenchecking for syntax errors without a configured Python version, Ruff now defaults to Python 3.15
instead of 3.14.
Update the default rule set (#28786)
Several of the
flake8-datetimezrules(
DTZ001,DTZ005,DTZ006,DTZ007,DTZ011,DTZ012, andDTZ901) are no longer enabled by default,while
undefined-local-with-nested-import-star-usage(
F406), which corresponds to a syntax error, is now enabled by default.Update Rust crate quick-junit to 0.8.0 (#27295)
JUnit output now uses a
skippedattribute instead ofdisabledon<testsuite>elements andincludes a
skippedattribute on the root<testsuites>element.[
flake8-import-conventions] Adddatetime as dtas a conventional alias (ICN001) (#28790)Support Unicode dummy variable names (#28722)
The default
lint.dummy-variable-rgxnow recognizes underscore-prefixed Unicode names, such as
_次, as dummy variables.Update to Unicode 17 (#21229, #28784)
Ruff now uses Unicode 17 data for identifier normalization and named character escapes (
"\N{...}").Always show unsafe and display-only fixes in the CLI (#27810)
The default
fulloutput format now shows unsafe fixes and suggestions requiring manual review,regardless of the
unsafe-fixessetting.Actually applying unsafe fixes still requires explicit opt-in.
Remove the Python dependency from conda-forge builds (conda-forge/ruff-feedstock#361)
The conda-forge build no longer depends on Python, now supports linux-riscv64, win-arm64, and
linux-ppc64le platforms, and now includes shell completions. However, no longer depending on
Python means that
python -m ruffandimport ruffwill no longer work. Useruffdirectly fromPATHinstead. PyPI installations and those from the standalone installer are unaffected.Remove support for ruff-lsp (#28750)
Support for
ruff-lsp, the legacy Python language server deprecated in Ruffv0.9.5, has been removed. The Ruff VS Code
extension now always uses the native language server;
ruff.nativeServeris deprecated andignored. See the migration guide.
Stabilization
The following rules have been stabilized and are no longer in preview:
lazy-import-mismatch(TID254)lazy-import-immediately-resolved(
TID255)os-path-commonprefix(RUF071)The following behaviors have been stabilized:
unsorted-imports(I001),line-too-long(E501), anddoc-line-too-long(W505) nowconsistently ignore trailing pragma comments when computing line length. This resolved several
bugs involving interactions between these rules
(#27313) but may also cause existing imports to be
reformatted and was thus classified as a breaking change.

Release Notes
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:Fixes are now shown in
checkandformat --checkoutput:This example also shows off the Markdown formatting.
format --checknow supports the same output formats as the linter, including thegithubandgitlaboutputs for rendering annotations in CI:See 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.Preview features
