## 0.4.5

### 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](https://github.com/astral-sh/ruff-vscode?tab=readme-ov-file#enabling-the-rust-based-language-server) today.

## 0.4.0

### 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](https://astral.sh/blog/ruff-v0.4.0) for more details!

See [#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).
