+==============================================================
+Important: #76166 - X-UA-Compatible not set in backend anymore
+==============================================================
+
+See :issue:`76166`
+
+Description
+===========
+
+As the official recommendation of Microsoft regarding the X-UA-Compatible tag is to not set this in the HTML code but instead via server configuration, the tag is not rendered by default in the backend anymore.
+
+The TYPO3 default `.htaccess` and `web.config` files already contain the corresponding settings. If you are using Internet Explorer configured to use compat mode by default, you may need to set these settings to ensure `edge` mode.
