Breaking changes

Ruff now formats your code according to the 2025 style guide. As a result, your code might now get formatted differently. See the formatter section for a detailed list of changes.

This release doesn’t remove or remap any existing stable rules.

Stabilization

The following rules have been stabilized and are no longer in preview:

- [`stdlib-module-shadowing`](https://docs.astral.sh/ruff/rules/stdlib-module-shadowing/) (`A005`).
 This rule has also been renamed: previously, it was called `builtin-module-shadowing`.
- [`builtin-lambda-argument-shadowing`](https://docs.astral.sh/ruff/rules/builtin-lambda-argument-shadowing/) (`A006`)
- [`slice-to-remove-prefix-or-suffix`](https://docs.astral.sh/ruff/rules/slice-to-remove-prefix-or-suffix/) (`FURB188`)
- [`boolean-chained-comparison`](https://docs.astral.sh/ruff/rules/boolean-chained-comparison/) (`PLR1716`)
- [`decimal-from-float-literal`](https://docs.astral.sh/ruff/rules/decimal-from-float-literal/) (`RUF032`)
- [`post-init-default`](https://docs.astral.sh/ruff/rules/post-init-default/) (`RUF033`)
- [`useless-if-else`](https://docs.astral.sh/ruff/rules/useless-if-else/) (`RUF034`)

The following behaviors have been stabilized:

- [`pytest-parametrize-names-wrong-type`](https://docs.astral.sh/ruff/rules/pytest-parametrize-names-wrong-type/) (`PT006`): Detect [`pytest.parametrize`](https://docs.pytest.org/en/7.1.x/how-to/parametrize.html#parametrize) calls outside decorators and calls with keyword arguments.
- [`module-import-not-at-top-of-file`](https://docs.astral.sh/ruff/rules/module-import-not-at-top-of-file/) (`E402`): Ignore [`pytest.importorskip`](https://docs.pytest.org/en/7.1.x/reference/reference.html#pytest-importorskip) calls between import statements.
- [`mutable-dataclass-default`](https://docs.astral.sh/ruff/rules/mutable-dataclass-default/) (`RUF008`) and [`function-call-in-dataclass-default-argument`](https://docs.astral.sh/ruff/rules/function-call-in-dataclass-default-argument/) (`RUF009`): Add support for [`attrs`](https://www.attrs.org/en/stable/).
- [`bad-version-info-comparison`](https://docs.astral.sh/ruff/rules/bad-version-info-comparison/) (`PYI006`): Extend the rule to check non-stub files.

The following fixes or improvements to fixes have been stabilized:

- [`redundant-numeric-union`](https://docs.astral.sh/ruff/rules/redundant-numeric-union/) (`PYI041`)
- [`duplicate-union-members`](https://docs.astral.sh/ruff/rules/duplicate-union-member/) (`PYI016`)

Formatter

This release introduces the new 2025 stable style ([13371](https://github.com/astral-sh/ruff/issues/13371)), stabilizing the following changes:

- Format expressions in f-string elements ([7594](https://github.com/astral-sh/ruff/issues/7594))
- Alternate quotes for strings inside f-strings ([13860](https://github.com/astral-sh/ruff/pull/13860))
- Preserve the casing of hex codes in f-string debug expressions ([14766](https://github.com/astral-sh/ruff/issues/14766))
- Choose the quote style for each string literal in an implicitly concatenated f-string rather than for the entire string ([13539](https://github.com/astral-sh/ruff/pull/13539))
- Automatically join an implicitly concatenated string into a single string literal if it fits on a single line ([9457](https://github.com/astral-sh/ruff/issues/9457))
- Remove the [`ISC001`](https://docs.astral.sh/ruff/rules/single-line-implicit-string-concatenation/) incompatibility warning ([#15123](https://github.com/astral-sh/ruff/pull/15123))
- Prefer parenthesizing the `assert` message over breaking the assertion expression ([9457](https://github.com/astral-sh/ruff/issues/9457))
- Automatically parenthesize over-long `if` guards in `match` `case` clauses ([13513](https://github.com/astral-sh/ruff/pull/13513))
- More consistent formatting for `match` `case` patterns ([6933](https://github.com/astral-sh/ruff/issues/6933))
- Avoid unnecessary parentheses around return type annotations ([13381](https://github.com/astral-sh/ruff/pull/13381))
- Keep the opening parentheses on the same line as the `if` keyword for comprehensions where the condition has a leading comment ([12282](https://github.com/astral-sh/ruff/pull/12282))
- More consistent formatting for `with` statements with a single context manager for Python 3.8 or older ([10276](https://github.com/astral-sh/ruff/pull/10276))
- Correctly calculate the line-width for code blocks in docstrings when using `max-doc-code-line-length = "dynamic"` ([13523](https://github.com/astral-sh/ruff/pull/13523))

Preview features

- \[`flake8-bugbear`\] Implement `class-as-data-structure` (`B903`) ([9601](https://github.com/astral-sh/ruff/pull/9601))
- \[`flake8-type-checking`\] Apply `quoted-type-alias` more eagerly in `TYPE_CHECKING` blocks and ignore it in stubs (`TC008`) ([15180](https://github.com/astral-sh/ruff/pull/15180))
- \[`pylint`\] Ignore `eq-without-hash` in stub files (`PLW1641`) ([15310](https://github.com/astral-sh/ruff/pull/15310))
- \[`pyupgrade`\] Split `UP007` into two individual rules: `UP007` for `Union` and `UP045` for `Optional` (`UP007`, `UP045`) ([15313](https://github.com/astral-sh/ruff/pull/15313))
- \[`ruff`\] New rule that detects classes that are both an enum and a `dataclass` (`RUF049`) ([15299](https://github.com/astral-sh/ruff/pull/15299))
- \[`ruff`\] Recode `RUF025` to `RUF037` (`RUF037`) ([15258](https://github.com/astral-sh/ruff/pull/15258))

Rule changes

- \[`flake8-builtins`\] Ignore [`stdlib-module-shadowing`](https://docs.astral.sh/ruff/rules/stdlib-module-shadowing/) in stub files(`A005`) ([#15350](https://github.com/astral-sh/ruff/pull/15350))
- \[`flake8-return`\] Add support for functions returning `typing.Never` (`RET503`) ([15298](https://github.com/astral-sh/ruff/pull/15298))

Server

- Improve the observability by removing the need for the ["trace" value](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#traceValue) to turn on or off logging. The server logging is solely controlled using the [`logLevel` server setting](https://docs.astral.sh/ruff/editors/settings/#loglevel)
 which defaults to `info`. This addresses the issue where users were notified about an error and told to consult the log, but it didn’t contain any messages. ([15232](https://github.com/astral-sh/ruff/pull/15232))
- Ignore diagnostics from other sources for code action requests ([15373](https://github.com/astral-sh/ruff/pull/15373))

CLI

- Improve the error message for `--config key=value` when the `key` is for a table and it’s a simple `value`

Bug fixes

- \[`eradicate`\] Ignore metadata blocks directly followed by normal blocks (`ERA001`) ([15330](https://github.com/astral-sh/ruff/pull/15330))
- \[`flake8-django`\] Recognize other magic methods (`DJ012`) ([15365](https://github.com/astral-sh/ruff/pull/15365))
- \[`pycodestyle`\] Avoid false positives related to type aliases (`E252`) ([15356](https://github.com/astral-sh/ruff/pull/15356))
- \[`pydocstyle`\] Avoid treating newline-separated sections as sub-sections (`D405`) ([15311](https://github.com/astral-sh/ruff/pull/15311))
- \[`pyflakes`\] Remove call when removing final argument from `format` (`F523`) ([15309](https://github.com/astral-sh/ruff/pull/15309))

- \[`ruff`\] Treat `)` as a regex metacharacter (`RUF043`, `RUF055`) ([15318](https://github.com/astral-sh/ruff/pull/15318))
- \[`ruff`\] Parenthesize the `int`-call argument when removing the `int` call would change semantics (`RUF046`) ([15277](https://github.com/astral-sh/ruff/pull/15277))
