 This option allows users to override CSS minification specifically instead of defaulting to `build.minify`, so you can configure minification for JS and CSS separately. Vite uses `esbuild` by default to minify CSS. Set the option to `'lightningcss'` to use [Lightning CSS](https://lightningcss.dev/minification.html) instead. If selected, it can be configured using [`css.lightningcss`](./shared-options.md#css-lightningcss).

 The experimental Vite Runtime API evolved into the Module Runner API, released in Vite 6 as part of the new experimental [Environment API](/guide/api-environment). Given that the feature was experimental the removal of the previous API introduced in Vite 5.1 isn't a breaking change, but users will need to update their use to the Module Runner equivalent as part of migrating to Vite 6.
 
+## General Changes
+
+### JSON stringify
+
+In Vite 5, when [`json.stringify: true`](/config/shared-options#json-stringify) is set, [`json.namedExports`](/config/shared-options#json-namedexports) was disabled.
+
+From Vite 6, even when `json.stringify: true` is set, `json.namedExports` is not disabled and the value is respected. If you wish to achieve the previous behavior, you can set `json.namedExports: false`.
+
+Vite 6 also introduces a new default value for `json.stringify` which is `'auto'`, which will only stringify large JSON files. To disable this behavior, set `json.stringify: false`.
+
+## Advanced
+
+There are other breaking changes which only affect few users.
+
+- [[#15637] fix!: default `build.cssMinify` to `'esbuild'` for SSR](https://github.com/vitejs/vite/pull/15637)
+  - [`build.cssMinify`](/config/build-options#build-cssminify) is now enabled by default even for SSR builds.
+- [[#18209] refactor!: bump minimal terser version to 5.16.0](https://github.com/vitejs/vite/pull/18209)
+  - Minimal supported terser version for [`build.minify: 'terser'`](/config/build-options#build-minify) was bumped to 5.16.0 from 5.4.0.
+- [[#18243] chore(deps)!: migrate `fast-glob` to `tinyglobby`](https://github.com/vitejs/vite/pull/18243)
+  - Range braces (`{01..03}` ⇒ `['01', '02', '03']`) and incremental braces (`{2..8..2}` ⇒ `['2', '4', '6', '8']`) are no longer supported in globs.
