0.8.0

Check out the [blog post](https://astral.sh/blog/ruff-v0.8.0) for a migration guide and overview of the changes!

Breaking changes

See also, the "Remapped rules" section which may result in disabled rules.

- **Default to Python 3.9**

 Ruff now defaults to Python 3.9 instead of 3.8 if no explicit Python version is configured using [`ruff.target-version`](https://docs.astral.sh/ruff/settings/#target-version) or [`project.requires-python`](https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#python-requires) ([13896](https://github.com/astral-sh/ruff/pull/13896))

- **Changed location of `pydoclint` diagnostics**

 [`pydoclint`](https://docs.astral.sh/ruff/rules/#pydoclint-doc) diagnostics now point to the first-line of the problematic docstring. Previously, this was not the case.

 If you've opted into these preview rules but have them suppressed using
 [`noqa`](https://docs.astral.sh/ruff/linter/#error-suppression) comments in
 some places, this change may mean that you need to move the `noqa` suppression
 comments. Most users should be unaffected by this change.

- **Use XDG (i.e. `~/.local/bin`) instead of the Cargo home directory in the standalone installer**

 Previously, Ruff's installer used `$CARGO_HOME` or `~/.cargo/bin` for its target install directory. Now, Ruff will be installed into `$XDG_BIN_HOME`, `$XDG_DATA_HOME/../bin`, or `~/.local/bin` (in that order).

 This change is only relevant to users of the standalone Ruff installer (using the shell or PowerShell script). If you installed Ruff using uv or pip, you should be unaffected.

- **Changes to the line width calculation**

 Ruff now uses a new version of the [unicode-width](https://github.com/unicode-rs/unicode-width) Rust crate to calculate the line width. In very rare cases, this may lead to lines containing Unicode characters being reformatted, or being considered too long when they were not before ([`E501`](https://docs.astral.sh/ruff/rules/line-too-long/)).

Removed Rules

The following deprecated rules have been removed:

- [`missing-type-self`](https://docs.astral.sh/ruff/rules/missing-type-self/) (`ANN101`)
- [`missing-type-cls`](https://docs.astral.sh/ruff/rules/missing-type-cls/) (`ANN102`)
- [`syntax-error`](https://docs.astral.sh/ruff/rules/syntax-error/) (`E999`)
- [`pytest-missing-fixture-name-underscore`](https://docs.astral.sh/ruff/rules/pytest-missing-fixture-name-underscore/) (`PT004`)
- [`pytest-incorrect-fixture-name-underscore`](https://docs.astral.sh/ruff/rules/pytest-incorrect-fixture-name-underscore/) (`PT005`)
- [`unpacked-list-comprehension`](https://docs.astral.sh/ruff/rules/unpacked-list-comprehension/) (`UP027`)

Remapped rules

The following rules have been remapped to new rule codes:

- [`flake8-type-checking`](https://docs.astral.sh/ruff/rules/#flake8-type-checking-tc): `TCH` to `TC`

- [`unnecessary-default-type-args`](https://docs.astral.sh/ruff/rules/unnecessary-default-type-args/) (`UP043`)

The following behaviors have been stabilized:

0.7.0

Check out the [blog post](https://astral.sh/blog/ruff-v0.7.0) for a migration guide and overview of the changes!

Breaking changes

- The pytest rules `PT001` and `PT023` now default to omitting the decorator parentheses when there are no arguments
 ([12838](https://github.com/astral-sh/ruff/pull/12838), [#13292](https://github.com/astral-sh/ruff/pull/13292)).
 This was a change that we attempted to make in Ruff v0.6.0, but only partially made due to an error on our part.
 See the [blog post](https://astral.sh/blog/ruff-v0.7.0) for more details.
- The `useless-try-except` rule (in our `tryceratops` category) has been recoded from `TRY302` to
 `TRY203` ([13502](https://github.com/astral-sh/ruff/pull/13502)). This ensures Ruff's code is consistent with
 the same rule in the [`tryceratops`](https://github.com/guilatrova/tryceratops) linter.
- The `lint.allow-unused-imports` setting has been removed ([13677](https://github.com/astral-sh/ruff/pull/13677)). Use
 [`lint.pyflakes.allow-unused-imports`](https://docs.astral.sh/ruff/settings/#lint_pyflakes_allowed-unused-imports)
 instead.

0.6.1

This is a hotfix release to address an issue with `ruff-pre-commit`. In v0.6,
Ruff changed its behavior to lint and format Jupyter notebooks by default;
however, due to an oversight, these files were still excluded by default if
Ruff was run via pre-commit, leading to inconsistent behavior.
This has [now been fixed](https://github.com/astral-sh/ruff-pre-commit/pull/96).

Server

- Fix crash when applying "fix-all" code-action to notebook cells ([12929](https://github.com/astral-sh/ruff/pull/12929))
