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

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.
