 - Feishu/reply delivery reliability: disable block streaming in Feishu reply options so plain-text auto-render replies are no longer silently dropped before final delivery. (#38258) Thanks @xinhuagu.
 - Agents/reply MEDIA delivery: normalize local assistant `MEDIA:` paths before block/final delivery, keep media dedupe aligned with message-tool sends, and contain malformed media normalization failures so generated files send reliably instead of falling back to empty responses. (#38572) Thanks @obviyus.
 - Sessions/bootstrap cache rollover invalidation: clear cached workspace bootstrap snapshots whenever an existing `sessionKey` rolls to a new `sessionId` across auto-reply, command, and isolated cron session resolvers, so `AGENTS.md`/`MEMORY.md`/`USER.md` updates are reloaded after daily, idle, or forced session resets instead of staying stale until gateway restart. (#38494) Thanks @LivingInDrm.
+- Gateway/Telegram polling health monitor: skip stale-socket restarts for Telegram long-polling channels and thread channel identity through shared health evaluation so polling connections are not restarted on the WebSocket stale-socket heuristic. (#38395) Thanks @ql-wade and @Takhoffman.
