 ### Features
 
+- On Windows, and with screenshot capture enabled, the SDK will now also capture and attach a screenshot to native crashes ([#2434](https://github.com/getsentry/sentry-unity/pull/2434))
 - Added `SetBeforeSendScreenshot(Func<Texture2D, SentryEvent, Texture2D?>)` callback that provides the captured screenshot as a
