+        <ul><h4>Compatibility and requirements</h4>
             <li>Vaadin now requires Java 8 or later and Servlet 3.0 or later</li>
             <li>Support for older browsers (including Microsoft IE 8-10) and Windows Phone has been dropped</li>
-            <li>A new data binding API replaces the old API (including Container, Item, Property, FieldGroup, Validator, Converter and components using those).</li>
-            <li>The default width of Label is now undefined, matching other components</li>
-            <li>Immediate mode is the default for all components except Upload</li>
-            <li>Some deprecated/obsolete parts of API (including the Form component) have been removed</li>
-            <li>Most addListener/removeListener methods have been removed - use the Java 8 friendly addClickListener(), addValueChangeListener() etc. instead</li>
-            <li>Many new listeners are unregistered using a Registration object returned by addXyzListener() rather than with a separate removeXyzListener()</li>
-            <li>Old input prompts have been replaced with placeholders utilizing the related browser functionality</li>
