 # @astrojs/starlight
 
+## 0.42.0
+
+### Minor Changes
+
+- [#3572](https://github.com/withastro/starlight/pull/3572) [`292fb17`](https://github.com/withastro/starlight/commit/292fb179cbf6e2cd970ced46359c520aa14a80b4) Thanks [@HiDeoo](https://github.com/HiDeoo)! - Distributes package as JavaScript files with dedicated type declaration files instead of TypeScript source files.
+
+- [#4121](https://github.com/withastro/starlight/pull/4121) [`2623ae6`](https://github.com/withastro/starlight/commit/2623ae60af0fdafc71938f96153b0427fcc2b5aa) Thanks [@delucis](https://github.com/delucis)! - Simplifies markup for Starlight’s mobile menu toggle
+
+  **⚠️ Potentially breaking change:** If you use a theme plugin, custom styles, or component overrides targeting the `MobileMenuToggle` button or `PageFrame` components, you may need to adjust these for the new markup. The button is no longer wrapped in a `<starlight-menu-button>` custom element and no longer uses the `aria-expanded` attribute. Instead, you can use the `.sl-menu-button` class name to target the button and the `:popover-open` pseudo-class to style the menu open state specifically.
+
+  In the following example, custom styles for the menu button are updated for the new approach:
+
+  ```diff
+  - starlight-menu-button button {
+  + .sl-menu-button {
+    color: var(--sl-color-text);
+  }
+
+  - starlight-menu-button[aria-expanded='true'] button {
+  + .sl-menu-button:has(~ :popover-open) {
+    color: var(--sl-color-text-accent-high);
+  }
+  ```
+
+  See [`MobileMenuToggle.astro`](https://github.com/withastro/starlight/blob/main/packages/starlight/components/MobileMenuToggle.astro) and [`PageFrame.astro`](https://github.com/withastro/starlight/blob/main/packages/starlight/components/PageFrame.astro) on GitHub for the full source code of the updated components.

+
+  If your configuration included a `tagline` option, you can safely remove it without any replacement.
+
+- [#4134](https://github.com/withastro/starlight/pull/4134) [`6135f01`](https://github.com/withastro/starlight/commit/6135f015b527453d7083ad01d2dc6c61d72fbefc) Thanks [@HiDeoo](https://github.com/HiDeoo)! - Updates internal `@astrojs/mdx`, `@astrojs/markdown-satteri`, and `satteri` dependencies.
+
+  ⚠️ **BREAKING CHANGE:** The following minimum versions are now required:
+
+  - `astro` v7.2.10 or later
+  - `@astrojs/markdown-satteri` 0.4.0 or later (if you use it)
+  - `@astrojs/markdown-remark` 7.3.0 or later (if you use it)
+
+  Please update Starlight and Astro together:
+
+  ```sh
+  npx @astrojs/upgrade
+  ```
+
+- [#4121](https://github.com/withastro/starlight/pull/4121) [`2623ae6`](https://github.com/withastro/starlight/commit/2623ae60af0fdafc71938f96153b0427fcc2b5aa) Thanks [@delucis](https://github.com/delucis)! - Refactors Starlight’s mobile menu toggle to work when JavaScript fails or is disabled
+
+  ⚠️ **BREAKING CHANGE:** This release drops official support for Chromium-based browsers prior to version 116 (released August 2023), Safari-based browsers prior to version 17.0 (released September 2023), and Firefox prior to version 125 (released April 2024). You can find a list of currently supported browsers and their versions using this [browserslist query](https://browsersl.ist/#q=%3E+0.5%25%2C+not+dead%2C+Chrome+%3E%3D+116%2C+Edge+%3E%3D+116%2C+Firefox+%3E%3D+125%2C+Safari+%3E%3D+17.0%2C+iOS+%3E%3D+17.0%2C+not+op_mini+all).
+
+  This change also removes the `data-mobile-menu-expanded` attribute, which was previously added to `<body>` while the mobile menu is open. If you have custom code that was depending on this attribute, you will need to update it to use a new selector to check if the mobile menu is open.
+
+  In the following example, a custom background colour for the site header while the menu is open is updated for the new approach:
+
+  ```diff
+  - [data-mobile-menu-expanded] header {
+  + body:has(sl-sidebar-pane:popover-open) header {
+    background-color: var(--sl-color-bg);
+  }
+  ```
