+
+The Vite plugin now uses a newer, faster, Vite-based compiler by default.
+
+The new compiler uses [`vite-node`](https://github.com/vitest-dev/vitest/tree/main/packages/vite-node) to parse and extract CSS from `.css.ts` files. This comes with all the benefits of using Vite, faster builds and the ability to use Vite plugins.
+
+The new compiler has been used in Remix ever since support for Vanilla Extract was introduced.

+
+The behaviour previously known as `emitCssInSsr` has been turned on by default. The `emitCssInSsr` option has been removed.
+
+This means that the CSS emitted by the plugin is now processed by Vite, so the plugin no longer needs to resolve PostCSS plugins and process the CSS output itself.
