 - Discard envelopes on `4xx` and `5xx` response ([#4950](https://github.com/getsentry/sentry-java/pull/4950))
   - This aims to not overwhelm Sentry after an outage or load shedding (including HTTP 429) where too many events are sent at once
 
+### Feature
+
+- Add a Tombstone integration that detects native crashes without relying on the NDK integration, but instead using `ApplicationExitInfo.REASON_CRASH_NATIVE` on Android 12+. ([#4933](https://github.com/getsentry/sentry-java/pull/4933))
+  - Currently exposed via options as an _internal_ API only.
+  - If enabled alongside the NDK integration, crashes will be reported as two separate events. Users should enable only one; deduplication between both integrations will be added in a future release.
