@@ -11,6 +11,7 @@ Docs: https://docs.openclaw.ai
 - Voice Call/realtime: add opt-in OpenClaw agent voice context capsules and consult-cadence guidance so Gemini/OpenAI realtime calls can sound like the configured agent without consulting the full agent on every ordinary turn. Thanks @scoootscooob.
 - Docker/Gateway: harden the gateway container by dropping `NET_RAW` and `NET_ADMIN` capabilities and enabling `no-new-privileges` in the bundled `docker-compose.yml`. Thanks @VintageAyu.
 - Telegram: accept plugin-owned numeric forum-topic targets in the agent message tool and keep reply-dispatch provider chunks behind a real stable runtime alias during in-place package updates. Fixes #77137. Thanks @richardmqq.
+- Telegram/streaming: keep draft preview rotation from reusing a pre-tool assistant preview after visible tool or media output lands between compaction replay and the next assistant message. Thanks @vincentkoc.
 - Channels/WhatsApp: support explicit WhatsApp Channel/Newsletter `@newsletter` outbound message targets with channel session metadata instead of DM routing. Fixes #13417; carries forward the narrow outbound target idea from #13424. Thanks @vincentkoc and @agentz-manfred.
 - TTS/telephony: honor provider voice/model overrides in telephony synthesis providers so Google Meet agent speech logs match the backend that actually produced the audio. Thanks @vincentkoc.
 - Voice Call/realtime: bound the paced Twilio audio queue and close overloaded realtime streams before provider audio can pile up behind the websocket backpressure guard. Thanks @vincentkoc.
