@@ -50,6 +50,7 @@ Docs: https://docs.openclaw.ai
 - Doctor/config: restore legacy group chat config migrations for `routing.allowFrom`, `routing.groupChat.*`, and `channels.telegram.requireMention` so upgrades keep WhatsApp, Telegram, and iMessage group mention gates and history settings instead of leaving configs invalid or silently blocked. Thanks @scoootscooob.
 - fix(gateway): clamp unbound websocket auth scopes [AI]. (#77413) Thanks @pgondhi987.
 - Gate zalouser startup name matching [AI]. (#77411) Thanks @pgondhi987.
+- Active Memory: send a bounded latest-message search query to the recall worker so channel/runtime metadata does not become the memory search string. Fixes #65309. Thanks @joeykrug, @westley3601, @pimenov, and @tasi333.
 - fix(device-pair): require pairing scope for pair command [AI]. (#76377) Thanks @pgondhi987.
 - fix(qqbot): keep private commands off framework surface [AI]. (#77212) Thanks @pgondhi987.
 - Claude CLI: honor non-off `/think` levels by passing Claude Code's session-scoped `--effort` flag through the CLI backend seam, so chat bridges no longer show an inert thinking control. Fixes #77303. Thanks @Petr1t.
