 ## Unreleased
 
+**Features**
+
+ Add user feedback capability to the Native SDK ([#966](https://github.com/getsentry/sentry-native/pull/966))
+
 **Internal**:
 
 - Remove the `CRASHPAD_WER_ENABLED` build flag. The WER module is now built for all supported Windows targets, and registration is conditional on runtime Windows version checks. ([#950](https://github.com/getsentry/sentry-native/pull/950), [crashpad#96](https://github.com/getsentry/crashpad/pull/96))
