Released on 2026-02-19.
##### Preview features
- Expand the default rule set
([#​23385](https://redirect.github.com/astral-sh/ruff/pull/23385))

mostly a
superset of the stable defaults, with the exception of these rules,

with
configuration like:
```toml
# ruff.toml
[lint]
select = ["E4", "E7", "E9", "F"]
# pyproject.toml
[tool.ruff.lint]
select = ["E4", "E7", "E9", "F"]
```

[`v0.15.0`](https://redirect.github.com/astral-sh/ruff/blob/HEAD/CHANGELOG.md#0150)
[Compare
Source](https://redirect.github.com/astral-sh/ruff/compare/0.14.14...0.15.0)
Released on 2026-02-03.
Check out the [blog post](https://astral.sh/blog/ruff-v0.15.0) for a
migration
guide and overview of the changes!
##### Breaking changes
- Ruff now formats your code according to the 2026 style guide. See the
formatter section below or in the blog post for a detailed list of
changes.
- The linter now supports block suppression comments. For example, to
suppress `N803` for all parameters in this function:
```python
# ruff: disable[N803]
def foo(
legacyArg1,
legacyArg2,
legacyArg3,
legacyArg4,
): ...
# ruff: enable[N803]
```
See the [documentation](https://docs.astral.sh/ruff/linter/#block-level)
for more details.
- The `ruff:alpine` Docker image is now based on Alpine 3.23 (up from
3.21).
- The `ruff:debian` and `ruff:debian-slim` Docker images are now based
on Debian 13 "Trixie" instead of Debian 12 "Bookworm."
- Binaries for the `ppc64` (64-bit big-endian PowerPC) architecture are
no longer included in our releases. It should still be possible to build
Ruff manually for this platform, if needed.
- Ruff now resolves all `extend`ed configuration files before falling
back on a default Python version.
##### Stabilization

(`UP043`) now applies to stub (`.pyi`) files on Python versions before
3.13.
##### Formatter
This release introduces the new 2026 style guide, with the following
changes:
- Lambda parameters are now kept on the same line and lambda bodies will
be parenthesized to let
them break across multiple lines
([#​21385](https://redirect.github.com/astral-sh/ruff/pull/21385))
- Parentheses around tuples of exceptions in `except` clauses will now
be removed on Python 3.14 and
later

- A single empty line is now permitted at the beginning of function
bodies
([#​21110](https://redirect.github.com/astral-sh/ruff/pull/21110))
- Parentheses are avoided for long `as` captures in `match` statements

be omitted

files
