DotNetBrowser 3.3.2

Chromium 139.0.7258.67

We upgraded Chromium to a newer version, which introduces 12 security fixes. Among them:

You can read more about it in the Chromium blog post.

End of support for macOS 11

Chromium 139 no longer supports macOS 11, so we also dropped support for this version in DotNetBrowser 3.3.2. The latest DotNetBrowser version that supports macOS 11 is 3.3.1.

Quality enhancements

  • The PropertyUpdateException exception type is added for better handling of the JavaScript object errors that occur on working with properties.
  • The NullReferenceException is no longer thrown from WinUI 3 BrowserView in the hardware-accelerated rendering mode when the browser is disposed.
  • The WinUI 3 BrowserView positioning issues were fixed for the hardware-accelerated rendering mode.
  • The issue with selecting the predefined media device from JavaScript was fixed. Before this fix, when the web page called getUserMedia({ audio: {deviceId: 'foo-bar'} }), the result of the callback was ignored. To make this scenario work properly, we modified the behavior of the SelectMediaDeviceResponse.Select(MediaDevice) method. It now selects only the given media device, and only this device will be visible to JavaScript.

Changed behavior

  • Since Chromium now always blocks third-party cookies in Incognito mode, they can no longer be enabled at the profile level.
