+### Widgets Updates
+
+Three new interfaces have been added for Widget Providers to implement: `IWidgetProvider2`, `IWidgetProviderAnalytics`, and `IWidgetProviderErrors`. `IWidgetProvider2` allows providers to respond to the *Customize* action invoked by the user, which is identical to what is available for 1st party Widgets. The `IWidgetProviderAnalytics` and `IWidgetProviderErrors` interfaces are used by providers to gather telemetry for their widgets; analytics and failure events about widgets are communicated to the respective widget providers. The `WidgetCustomizationRequestedArgs`, `WidgetAnalyticsInfoReportedArgs`, and `WidgetErrorInfoReportedArgs` classes are used to communicate relevant information to support new functionalities.

+### New features from across the WinAppSDK
+
+- A new `ThemeSettings` class that allows Win32 WinRT apps to detect when the system's High Contrast setting has changed, similar to UWP's [AccessibilitySettings](/uwp/api/windows.ui.viewmanagement.accessibilitysettings) class. See the [ThemeSettings API spec](https://github.com/microsoft/WindowsAppSDK/blob/main/specs/themes/ThemeSettings.md) on GitHub for more information.
+- - `Popup/FlyoutBase.ShouldConstrainToRootBounds` is now supported to allow tooltips, menus, and other popups to extend outside the bounds of the main window. Preview 1 does not yet fully support having Acrylic or other SystemBackdrops on a popup/flyout; additional APIs and implementation for this will be included in the next 1.4 release.
+- `AccessKeyManager.EnterDisplayMode` is a new method to display access keys for the current focused element of a provided root. Access keys are in "display mode" when showing a key tip to invoke a command, such as pressing the Alt key in Paint to show what keys correspond to what controls. This method allows for programmatically entering display mode.
+- `Application.ResourceManagerRequested` provides a mechanism to provide a different `IResourceManager` to resolve resource URIs for scenarios when the default `ResourceManager` won't work. For more information, see the [Application.ResourceManagerRequested API spec](https://github.com/microsoft/microsoft-ui-xaml/blob/main/specs/custom-iresourcemanager-spec.md) on GitHub.
+- We're introducing a new list control called the `ItemsView` and a corresponding concrete `ItemContainer` class. `ItemContainer` is a lightweight container with built-in selection states and visuals, which can easily wrap desired content and be used with `ItemsView` for a collection control scenario. `ItemsView` is still marked experimental in Preview 1 but will be included in the next 1.4 release.
+- The version of the WebView2 SDK was updated from 1661.34 to [1823.32](/microsoft-edge/webview2/release-notes?tabs=winrtcsharp#10182332).
