-#### Preact = Dropped webpack5 builder support
+#### Dropped webpack5 Builder Support in Favor of Vite

-The packages `@storybook/preact-webpack5` and `@storybook/preset-preact-webpack5` have been removed. For Preact projects, please use the Vite builder instead:
+Removed webpack5 builder support for Preact, Vue3, and Web Components frameworks in favor of Vite builder. This change streamlines our builder support and improves performance across these frameworks.
+
+Removed Packages
+- `@storybook/preact-webpack5`
+- `@storybook/preset-preact-webpack5`
+- `@storybook/vue3-webpack5`
+- `@storybook/preset-vue3-webpack`
+- `@storybook/web-components-webpack5`
+
+**For Preact Projects**

 ```bash
 npm remove @storybook/preact-webpack5 @storybook/preset-preact-webpack
 npm install @storybook/preact-vite --save-dev
 ```

-Then update your `.storybook/main.js|ts`:
-
-```js
-export default {
-  framework: {
-    name: '@storybook/preact-vite',
-    options: {},
-  },
-  // ... other configurations
-};
-```
-
-#### Vue3 = Dropped webpack5 builder support
-
-The `@storybook/vue3-webpack5` package has been removed. For Vue3 projects, please use the Vite builder instead:
+**For Vue3 Projects**

 ```bash
 npm remove @storybook/vue3-webpack5 @storybook/preset-vue3-webpack
 npm install @storybook/vue3-vite --save-dev
 ```

-Then update your `.storybook/main.js|ts`:
+**For Web Components Projects**

-```js
+```bash
+npm remove @storybook/web-components-webpack5
+npm install @storybook/web-components-vite --save-dev
+```
+
+**Update .storybook/main.js|ts**
+
+For all affected frameworks, update your configuration to use the Vite builder:
+
+
+```tsx
 export default {
  framework: {
-    name: '@storybook/vue3-vite',
+    name: '@storybook/[framework]-vite', // replace [framework] with preact, vue3, or web-components
    options: {},
  },
  // ... other configurations
 };
 ```

+This change consolidates our builder support around Vite, which offers better performance and a more streamlined development experience. The webpack5 builders for these frameworks have been deprecated in favor of the more modern Vite-based solution.
+
 #### Next.js = Require v14 and up

 Storybook has dropped support for Next.js versions below 14.1. The minimum supported version is now Next.js 14.1.

-        Render pages with mock data. This makes it easy to build and review page states without
-        needing to navigate to them in your app. Here are some handy patterns for managing page data
-        in Storybook:
-      </p>
-      <ul>
-        <li>
-          Use a higher-level connected component. Storybook helps you compose such data from the
-          "args" of child component stories
-        </li>
-        <li>
-          Assemble data in the page component from your services. You can mock these services out
-          using Storybook.
-        </li>
-      </ul>

-        Render pages with mock data. This makes it easy to build and review page states without
-        needing to navigate to them in your app. Here are some handy patterns for managing page data
-        in Storybook:
-      </p>
-      <ul>
-        <li>
-          Use a higher-level connected component. Storybook helps you compose such data from the
-          "args" of child component stories
-        </li>
-        <li>
-          Assemble data in the page component from your services. You can mock these services out
-          using Storybook.
-        </li>
-      </ul>
