These Release Notes provide information about added features and bug fixes that are included in the WebView2 Release SDK and the WebView2 Prerelease SDK, for older releases.


<!-- Nov 2024 Release SDK -->
<!-- ====================================================================== -->
## 1.0.2903.40

Release Date: November 18, 2024

[NuGet package for WebView2 SDK 1.0.2903.40](https://www.nuget.org/packages/Microsoft.Web.WebView2/1.0.2903.40)

For full API compatibility, this Release version of the WebView2 SDK requires WebView2 Runtime version 131.0.2903.40 or higher.


<!-- ------------------------------ -->
#### Promotions

The following APIs have been promoted to Stable and are now included in this Release SDK.


<!-- ---------- -->
###### Control whether the screen capture UI is shown (ScreenCaptureStarting event)

Added a new `ScreenCaptureStarting` event. This event is raised whenever the WebView2 and/or iframe that corresponds to the `CoreWebView2Frame` (or to any of its descendant iframes) requests permission to use the Screen Capture API before the UI is shown. The app can then block the UI from being displayed, or allow the UI to be displayed.
