 ### IRootObjectProvider
 
-Not supported as of Uno 4.3
+With access to IRootObjectProvider becomes possible for a Markup extension to browse the visual tree, starting from the root of the XAML file.
+
+This following example [from the WinUI specifications](https://github.com/microsoft/microsoft-ui-xaml-specs/blob/34b14114af141ceb843413bedb85705c9a2e9204/active/XamlServiceProvider/XamlServiceProviderApi.md#irootobjectprovider) give a glimpse of this feature.
+
+Using the following XAML:
+
+```csharp
+public class DynamicBindExtension : MarkupExtension
+{
+    public DynamicBindExtension(string propertyName)
+    {
+        _propertyName = propertyName;
+    }
+    string _propertyName;
+
+    public override object ProvideValue(IXamlServiceProvider serviceProvider)
+    {
+        var root = ((IRootObjectProvider)serviceProvider.GetService(typeof(IRootObjectProvider))).RootObject;
+        var info = root.GetType().GetProperty(_propertyName);
+        return info.GetValue(root);
+    }
+}
+```
+
+The following XAML will display “Page Tag”:
+
+```xml
+<Page Tag='Page tag' 
+      x:Class="App1.MainPage"
+      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
+      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
+      xmlns:local="using:App52"
+      Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">

+        <TextBlock Text="{local:DynamicBind Tag}" />

 This article details the migration steps required to migrate from one version to the next when breaking changes are being introduced.
 
+## Uno Platform 5.4
+
+Uno Platform 5.4 contains breaking changes for Uno.Extensions.
+
+## WinAppSDK 1.6 considerations
+
+Uno Platform 5.4 updates to WinAppSDK 1.6 if you using the [`Uno.SDK`](xref:Uno.Features.Uno.Sdk), which requires a temporary version adjustment until newer versions of the .NET 8 SDKs are released.
+
+In your project, you may need to add the following lines (or uncomment them if you kept them from our templates) to get the `net8.0-windowsXX` target to build:
+
+```xml
+<PropertyGroup>
+    <!-- Remove when the .NET SDK 8.0.403 or later has been released -->
+    <WindowsSdkPackageVersion>10.0.19041.38</WindowsSdkPackageVersion>
+</PropertyGroup>
+```
+
+### UWP Support for Uno.Extensions
+
+The [`Uno.Extensions`](https://aka.platform.uno/uno-extensions) compatibility with legacy UWP apps has been removed. If your app is UWP-based and uses Uno.Extensions, in order to migrate to Uno Platform 5.4, you can keep using [previous releases of Uno.Extensions](https://github.com/unoplatform/uno.extensions/releases), or [migrate your app to WinUI](https://platform.uno/docs/articles/updating-to-winui3.html).
+
+All the other features of Uno Platform 5.4 continue to be compatible with both UWP and WinUI apps.
+
+### Updates in Uno.Extensions.Reactive
+
+The generated code has changed. Make sure to [review our docs to upgrade](xuid:Uno.Extensions.Reactive.Upgrading) to Uno Platform 5.4.
+
 ## Uno Platform 5.3
 
 Uno Platform 5.3 contains an improved template and Uno.SDK versioning, new default text font, and Rider support.
