+Feature: #92616 - Bootstrap v5
+==============================
+
+See :issue:`92616`
+
+Description
+===========
+
+TYPO3s Backend is powered with Bootstrap v5 (https://getbootstrap.com).
+
+Previous versions ran with Bootstrap v3. A lots of changes and
+improvements are included, especially regarding simplification
+of building Layouts and Containers.
+
+Backend modules which relied on Twitter Bootstrap v3 markup,
+or functionality in JavaScript, will have a slightly different
+and improved look & feel.
+
+
+Impact
+======
+
+It is important during updates of custom backend modules
+to study the Bootstrap Migration guidelines and adapt accordingly:
+
+* https://getbootstrap.com/docs/4.5/migration/
+* https://getbootstrap.com/docs/5.0/migration/
+
+TYPO3 Core still includes some legacy styling and functionality
+to provide compatibility, but backend markup and code will
+be adapted during further TYPO3 v11 development to simplify
+the HTML and CSS code shipped with TYPO3 Core.
