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.
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.

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 via logging methods other than critical, error and exception.
future-required-type-annotation
(FA102) now checks for additional PEP 585-compatible
APIs, such as those from collections.abc.
f-string-in-get-text-func-call
(INT001),
format-in-get-text-func-call
(INT002), and
printf-in-get-text-func-call
(INT003) now check for additional common ways of using the gettext module, such as assigning
it to builtins._.
suspicious-url-open-usage
(S310) now resolves local string literal bindings to avoid more false positives.
snmp-insecure-version (S508) and
snmp-weak-cryptography (S509) now
support the recommended API from newer versions of PySNMP.
typing-text-str-alias (UP019) now
recognizes typing_extensions.Text in addition to typing.Text.

Verifying GitHub Artifact Attestations

The artifacts in this release have attestations generated with GitHub Artifact Attestations. These can be verified by using the GitHub CLI:

gh attestation verify <file-path of downloaded artifact> --repo astral-sh/ruff

You can also download the attestation from GitHub and verify against that directly:

gh attestation verify <file-path of downloaded artifact> --bundle <file-path of downloaded attestation>

`v0.0.69`

Compare Source

Released on 2026-08-06.

Core type checking

isinstance narrowing for generic classes is now more gradual by default (#27308)

This new behavior is more similar to what other major type checkers do. For example:
```
def f(xs: object):
    if isinstance(xs, list):
        reveal_type(xs)  # now: `list[Unknown]`, before: `Top[list[Unknown]]`
```
Note: you might consider enabling analysis.strict-generic-narrowing
if you prefer the strictly correct behavior.
