Take note: the heading structure in the Adminadmin (and super admin) screens will change in WordPress 4.3.

From H2 to H1

If your theme or plugin still uses <h2> for admin screens, don’t worry; styles for <h2> are still supported in the admin CSS so that, visually, nothing changes during the update to 4.3.

<h1>Posts <a href="[..]/wp-admin/post-new.php" class="page-title-action">Add New</a></h1>

Does your plugin, theme, or framework have admin screens? Check the heading structure. Change the main heading from an <h2> into an <h1>. If you’re feeling generous, check the rest of your heading structure to ensure it’s semantic.

Making these semantic changes will ensure your plugin or theme is in sync with WordPress and that people using a screen reader can understand your admin screens better.
