 <h4 id="version-9x-card">Card</h4>
 
-- **ion-card**: The `border-radius` of the `ios` and `md` card now defaults to `14px` and `12px` instead of `8px` and `4px`, respectively, in accordance with the iOS and Material Design 3 guidelines. To revert to the previous appearance, set the `shape` to `"soft"`, or override the `--border-radius` CSS variable to specify a different value.
-
-- **ion-card-content**: The `ion-card-content` component has been updated to Shadow DOM. With this update, all card-related components now use Shadow DOM for style encapsulation. The default styles for heading elements inside `ion-card-content` have been removed. If you need custom styling for headings, you can add your own CSS targeting these elements. For example:
-
-  ```css
-  ion-card-content h1 {
-    margin-top: 0;
-    margin-bottom: 2px;
-
-    font-size: 1.5rem;
-  }
-
-  ion-card-content h2 {
-    margin-top: 2px;
-    margin-bottom: 2px;
-
-    font-size: 1rem;
-  }
-
-  ion-card-content h3,
-  ion-card-content h4,
-  ion-card-content h5,
-  ion-card-content h6 {
-    margin-top: 2px;
-    margin-bottom: 2px;

+- The `border-radius` of the `ios` and `md` card now defaults to `14px` and `12px` instead of `8px` and `4px`, respectively, in accordance with the iOS and Material Design 3 guidelines. To revert to the previous appearance, set the `shape` to `"soft"`, or override the `--border-radius` CSS variable to specify a different value.
 
 <h4 id="version-9x-chip">Chip</h4>
 
 - The `border-radius` of the `ios` and `md` chip now defaults to `10px` and `8px`, respectively, instead of `16px` in accordance with the iOS and Material Design 3 guidelines. To revert to the previous appearance, set the `shape` to `"round"`, or override the `--border-radius` CSS variable to specify a different value.
 
-<h4 id="version-9x-datetime">Datetime</h4>
-
-- The `ion-buttons` component has been removed from the internal implementation of `ion-datetime` and is no longer required when passing custom buttons to the `slot="buttons"`. When providing custom buttons, use a `div` element instead of `ion-buttons`. While existing code using `ion-buttons` may continue to work visually, future updates to the `ion-buttons` component may cause any styles you rely on to break.
-
 <h4 id="version-9x-grid">Grid</h4>
 
 - The properties `pull` and `push` have been deprecated and no longer work. A similar look can be achieved with the newly added property `order`.
 
+<h4 id="version-9x-radio-group">Radio Group</h4>

+- Converted `ion-radio-group` to use [Shadow DOM](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_shadow_DOM).<br/>
+If you were targeting the internals of `ion-radio-group` in your CSS, you will need to target the `supporting-text`, `helper-text` or `error-text` [Shadow Parts](https://ionicframework.com/docs/theming/css-shadow-parts) instead, or use the provided CSS Variables.<br/>
+Additionally, the `radio-group-wrapper` div element has been removed, causing slotted elements to be direct children of the `ion-radio-group`.
