 ### Changes
 
+- Gateway/Container probes: add built-in HTTP liveness/readiness endpoints (`/health`, `/healthz`, `/ready`, `/readyz`) for Docker/Kubernetes health checks, with fallback routing so existing handlers on those paths are not shadowed. (#31272) Thanks @vincentkoc.
 - Android/Nodes: add `camera.list`, `device.permissions`, `device.health`, and `notifications.actions` (`open`/`dismiss`/`reply`) on Android nodes, plus first-class node-tool actions for the new device/notification commands. (#28260) Thanks @obviyus.
 - Discord/Thread bindings: replace fixed TTL lifecycle with inactivity (`idleHours`, default 24h) plus optional hard `maxAgeHours` lifecycle controls, and add `/session idle` + `/session max-age` commands for focused thread-bound sessions. (#27845) Thanks @osolmaz.
 - Telegram/DM topics: add per-DM `direct` + topic config (allowlists, `dmPolicy`, `skills`, `systemPrompt`, `requireTopic`), route DM topics as distinct inbound/outbound sessions, and enforce topic-aware authorization/debounce for messages, callbacks, commands, and reactions. Landed from contributor PR #30579 by @kesor. Thanks @kesor.
