 ### Fixes
 
 - Feishu/Probe status caching: cache successful `probeFeishu()` bot-info results for 10 minutes (bounded cache with per-account keying) to reduce repeated status/onboarding probe API calls, while bypassing cache for failures and exceptions. (#28907) Thanks @Glucksberg.
+- Feishu/Opus media send type: send `.opus` attachments with `msg_type: "audio"` (instead of `"media"`) so Feishu voice messages deliver correctly while `.mp4` remains `msg_type: "media"` and documents remain `msg_type: "file"`. (#28269) Thanks @Glucksberg.
 - Feishu/Local media sends: propagate `mediaLocalRoots` through Feishu outbound media sending into `loadWebMedia` so local path attachments work with post-CVE local-root enforcement. (#27884) Thanks @joelnishanth.
 - Security/Feishu webhook ingress: bound unauthenticated webhook rate-limit state with stale-window pruning and a hard key cap to prevent unbounded pre-auth memory growth from rotating source keys. (#26050) Thanks @bmendonca3.
 - Telegram/Reply media context: include replied media files in inbound context when replying to media, defer reply-media downloads to debounce flush, gate reply-media fetch behind DM authorization, and preserve replied media when non-vision sticker fallback runs (including cached-sticker paths). (#28488) Thanks @obviyus.
