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 (A005).
    This rule has also been renamed: previously, it was called \ 
builtin-module-shadowing.
    builtin-lambda-argument-shadowing (A006)
    slice-to-remove-prefix-or-suffix (FURB188)
    boolean-chained-comparison (PLR1716)
    decimal-from-float-literal (RUF032)
    post-init-default (RUF033)
    useless-if-else (RUF034)

The following behaviors have been stabilized:

    pytest-parametrize-names-wrong-type (PT006): Detect pytest.parametrize calls \ 
outside decorators and calls with keyword arguments.
    module-import-not-at-top-of-file (E402): Ignore pytest.importorskip calls \ 
between import statements.
    mutable-dataclass-default (RUF008) and \ 
function-call-in-dataclass-default-argument (RUF009): Add support for attrs.
    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 (PYI041)
    duplicate-union-members (PYI016)

Formatter

This release introduces the new 2025 stable style (#13371), stabilizing the \ 
following changes:

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

Preview features

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

    [flake8-return] Add support for functions returning typing.Never (RET503) \ 
(#15298)

Server

    Improve the observability by removing the need for the "trace" \ 
value to turn on or off logging. The server logging is solely controlled using \ 
the logLevel server setting
    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)
    Ignore diagnostics from other sources for code action requests (#15373)

CLI

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