@@ -51,6 +51,7 @@ Docs: https://docs.openclaw.ai
 - Gateway/startup: bound local discovery advertisement during startup, so a stuck discovery plugin can no longer keep the Gateway from reaching ready. Fixes #73865; refs #74630 and #74633. Thanks @lpendeavors, @moltar-bot, and @Saboor711.
 - Gateway/models: serve the last successful model catalog while stale reloads refresh in the background, so Gateway control-plane and OpenAI-compatible requests no longer block behind model-provider rediscovery after model config changes. Refs #74135, #74630, and #74633. Thanks @DerFlash, @moltar-bot, and @Saboor711.
 - CLI/status: resolve read-only channel setup runtime fallback from the packaged OpenClaw dist root, so `status --all`, `status --deep`, channel, and doctor paths do not crash when an external channel plugin needs setup metadata. Fixes #74693. Thanks @giangthb.
+- SDK/events: keep per-run SDK event streams from surfacing duplicate raw chat projection frames, while normalizing chat-only projection frames and preserving raw access through `rawEvents`. Refs #74704. Thanks @BunsDev.
 - Google Meet: block managed Chrome intro/test speech until browser health proves the participant is in-call, and expose `speechReady` diagnostics so login, admission, permission, and audio-bridge blockers no longer look like successful speech. Refs #72478. Thanks @DougButdorf.
 - Slack/commands: keep native command argument menus on select controls for encoded choice values up to Slack's option limit and truncate fallback button labels to Slack's button-text limit, so long valid choices no longer render invalid Slack blocks. Thanks @slackapi.
 - Agents/Codex: flush accepted debounced steering messages before normal app-server turn cleanup, so inbound follow-ups acknowledged as queued are not dropped when the turn completes before the debounce fires. Thanks @vincentkoc.
