 ## 0.4.0
 
+### A new, hand-written parser
+
+This release replaces the generated parser with a hand-written recursive descent parser in Ruff.
+There's a lot to say about this exciting change, so check out the [blog post](TODO-LINK) 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 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 project configuration when you change it
+
+To setup `ruff server` with your editor, refer to the [README.md](http://README.mdhttps://github.com/astral-sh/ruff/blob/main/crates/ruff_server/README.md).
