+
+### Minor Changes
+
+- [#2551](https://github.com/withastro/starlight/pull/2551) [`154c8e3`](https://github.com/withastro/starlight/commit/154c8e337819c7d7ebf4ff4dd55db0d10607620b) Thanks [@hippotastic](https://github.com/hippotastic)! - Updates the `astro-expressive-code` dependency to the latest version (0.38).
+
+  The new version allows using `ec.config.mjs` to selectively override individual Expressive Code styles and settings provided by Starlight themes and plugins, speeds up Shiki language loading, and adds the config option `expressiveCode.shiki.injectLangsIntoNestedCodeBlocks`. See the [Expressive Code release notes](https://expressive-code.com/releases/#0380) for full details.

+- [#2252](https://github.com/withastro/starlight/pull/2252) [`6116db0`](https://github.com/withastro/starlight/commit/6116db03a4157c0f0caa210690ef0dcdd001a287) Thanks [@HiDeoo](https://github.com/HiDeoo)! - Improves build performance for sites with large sidebars
+
+  This release adds a caching layer to Starlight’s sidebar generation logic, reducing the number of times sidebars need to be regenerated while building a site. Some benchmarks for projects with a complex sidebar saw builds complete more than 35% faster with this change.
