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 or project.requires-python (#​13896)

  • Changed location of pydoclint diagnostics

    pydoclint 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 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 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).

Removed Rules

The following deprecated rules have been removed:

Check out the blog post 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, #​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 for more details.
  • The useless-try-except rule (in our tryceratops category) has been recoded from TRY302 to
    TRY203 (#​13502). This ensures Ruff's code is consistent with
    the same rule in the tryceratops linter.
  • The lint.allow-unused-imports setting has been removed (#​13677). Use
    lint.pyflakes.allow-unused-imports
    instead.

v0.6.1

Compare Source

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.

A new, hand-written parser

Ruff's new parser is >2x faster, which translates to a 20-40% speedup for all linting and formatting invocations.
There's a lot to say about this exciting change, so check out the blog post for more details!

See #​10036 for implementation details.

A new language server in Rust

With this release, we also want to highlight our new language server. ruff server is a Rust-powered language
server that comes built-in with Ruff. It can be used with any editor that supports the Language Server Protocol (LSP).
It uses a multi-threaded, lock-free architecture inspired by rust-analyzer and it will open the door for a lot
of exciting features. It’s also faster than our previous Python-based language server
-- but you probably guessed that already.

ruff server is only in alpha, but it has a lot of features that you can try out today:

  • Lints Python files automatically and shows quick-fixes when available
  • Formats Python files, with support for range formatting
  • Comes with commands for quickly performing actions: ruff.applyAutofix, ruff.applyFormat, and ruff.applyOrganizeImports
  • Supports source.fixAll and source.organizeImports source actions
  • Automatically reloads your project configuration when you change it

To setup ruff server with your editor, refer to the README.md.

**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) ([#&#8203;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` ##### Stabilization The following rules have been stabilized and are no longer in preview: - [`builtin-import-shadowing`](https://docs.astral.sh/ruff/rules/builtin-import-shadowing/) (`A004`) - [`mutable-contextvar-default`](https://docs.astral.sh/ruff/rules/mutable-contextvar-default/) (`B039`) - [`fast-api-redundant-response-model`](https://docs.astral.sh/ruff/rules/fast-api-redundant-response-model/) (`FAST001`) - [`fast-api-non-annotated-dependency`](https://docs.astral.sh/ruff/rules/fast-api-non-annotated-dependency/) (`FAST002`) - [`dict-index-missing-items`](https://docs.astral.sh/ruff/rules/dict-index-missing-items/) (`PLC0206`) - [`pep484-style-positional-only-parameter`](https://docs.astral.sh/ruff/rules/pep484-style-positional-only-parameter/) (`PYI063`) - [`redundant-final-literal`](https://docs.astral.sh/ruff/rules/redundant-final-literal/) (`PYI064`) - [`bad-version-info-order`](https://docs.astral.sh/ruff/rules/bad-version-info-order/) (`PYI066`) - [`parenthesize-chained-operators`](https://docs.astral.sh/ruff/rules/parenthesize-chained-operators/) (`RUF021`) - [`unsorted-dunder-all`](https://docs.astral.sh/ruff/rules/unsorted-dunder-all/) (`RUF022`) - [`unsorted-dunder-slots`](https://docs.astral.sh/ruff/rules/unsorted-dunder-slots/) (`RUF023`) - [`assert-with-print-message`](https://docs.astral.sh/ruff/rules/assert-with-print-message/) (`RUF030`) - [`unnecessary-default-type-args`](https://docs.astral.sh/ruff/rules/unnecessary-default-type-args/) (`UP043`) The following behaviors have been stabilized: - [`ambiguous-variable-name`](https://docs.astral.sh/ruff/rules/ambiguous-variable-name/) (`E741`): Violations in stub files are now ignored. Stub authors typically don't control variable names. - [`printf-string-formatting`](https://docs.astral.sh/ruff/rules/printf-string-formatting/) (`UP031`): Report all `printf`-like usages even if no autofix is available The following fixes have been stabilized: -

The pytest rules `PT001` and `PT023` now default to omitting the decorator parentheses when there are no arguments ([#&#8203;12838](https://github.com/astral-sh/ruff/pull/12838), [#&#8203;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` ([#&#8203;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 ([#&#8203;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. ##### Formatter preview style - Normalize implicit concatenated f-string quotes per part ([#&#8203;13539](https://github.com/astral-sh/ruff/pull/13539)) ##### Preview linter features -

There's a lot to say about this exciting change, so check out the [blog post](https://astral.sh/blog/ruff-v0.4.0) for more details! See [#&#8203;10036](https://github.com/astral-sh/ruff/pull/10036) for implementation details. ##### A new language server in Rust With this release, we also want to highlight our new language server. `ruff server` is a Rust-powered language server that comes built-in with Ruff. It can be used with any editor that supports the [Language Server Protocol](https://microsoft.github.io/language-server-protocol/) (LSP). It uses a multi-threaded, lock-free architecture inspired by `rust-analyzer` and it will open the door for a lot of exciting features. It’s also faster than our previous [Python-based language server](https://github.com/astral-sh/ruff-lsp) \-- but you probably guessed that already. `ruff server` is only in alpha, but it has a lot of features that you can try out today: - Lints Python files automatically and shows quick-fixes when available - Formats Python files, with support for range formatting - Comes with commands for quickly performing actions: `ruff.applyAutofix`, `ruff.applyFormat`, and `ruff.applyOrganizeImports` - Supports `source.fixAll` and `source.organizeImports` source actions - Automatically reloads your project configuration when you change it To setup `ruff server` with your editor, refer to the [README.md](https://github.com/astral-sh/ruff/blob/main/crates/ruff_server/README.md). ##### Preview features -
