 ## Unreleased:
 
+**Features**:
+
+- Add `addAttachment` and `clearAttachments` to the NDK `NativeScope` API for managing file and byte attachments via JNI. ([#1584](https://github.com/getsentry/sentry-native/pull/1584))
+
 **Fixes**:
 
 - inproc: only the handling thread cleans up after the crash. ([#1579](https://github.com/getsentry/sentry-native/pull/1579))

 - Add logs flush on `sentry_flush()`. ([#1434](https://github.com/getsentry/sentry-native/pull/1434))
 - Add global attributes API. These are added to all `sentry_log_X` calls. ([#1450](https://github.com/getsentry/sentry-native/pull/1450))
