v0.6.1
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.

Breaking changes
See also, the "Remapped rules" section which may result in disabled rules.
- Follow the XDG specification to discover user-level configurations on macOS (same as on other Unix platforms)
- Selecting
ALL
now excludes deprecated rules - The released archives now include an extra level of nesting, which can be removed with
--strip-components=1
when untarring. - The release artifact's file name no longer includes the version tag. This enables users to install via
/latest
URLs on GitHub. - The diagnostic ranges for some
flake8-bandit
rules were modified (#10667).
Deprecations
The following rules are now deprecated:
-
syntax-error
(E999
): Syntax errors are now always shown

v0.4.5
Ruff's language server is now in Beta
v0.4.5
marks the official Beta release of ruff server
, an integrated language server built into Ruff.
ruff server
supports the same feature set as ruff-lsp
, powering linting, formatting, and
code fixes in Ruff's editor integrations -- but with superior performance and
no installation required. We'd love your feedback!
You can enable ruff server
in the VS Code extension today.

v0.4.0
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
, andruff.applyOrganizeImports
- Supports
source.fixAll
andsource.organizeImports
source actions - Automatically reloads your project configuration when you change it
To setup ruff server
with your editor, refer to the README.md.
