@@ -62,6 +62,7 @@ Docs: https://docs.openclaw.ai
 - TTS/SecretRef: resolve `messages.tts.providers.*.apiKey` from the active runtime snapshot so SecretRef-backed MiniMax and other TTS provider keys work in runtime reply/audio paths. Fixes #68690. Thanks @joshavant.
 - Gateway/install: surface systemd user-bus recovery hints during Linux service activation and retry via the target user scope when `systemctl --user` reports no-medium bus failures, without letting stale `SUDO_USER` override `sudo -u` installs. Fixes #39673; refs #44417 and #63561. Thanks @Arbor4, @myrsu, @mssteuer, and @boyuaner.
 - CLI/startup: read generated startup metadata from the bundled `dist` layout before falling back to live help rendering, so root/browser help and channel-option bootstrap stay on the fast path. Thanks @vincentkoc.
+- Feishu/Lark: stop treating broadcast-only `@all`/`@_all` messages as bot mentions while preserving direct bot mentions, including messages that also include `@all`. Fixes #37706. Thanks @JosepLee.
 - CLI/help: treat positional `help` invocations like `openclaw channels help` as help paths for startup gating, avoiding model/auth warmup while preserving positional arguments such as `openclaw docs help`. Thanks @gumadeiras.
 - Web search: route plugin-scoped web_search SecretRefs through the active runtime config snapshot so provider execution receives resolved credentials across app/runtime paths, including `plugins.entries.brave.config.webSearch.apiKey`. Fixes #68690. Thanks @VACInc.
 - Voice Call: allow SecretRef-backed Twilio auth tokens and call-specific OpenAI/ElevenLabs TTS API keys through the plugin config surface. Fixes #68690. Thanks @joshavant.
