 ### Changes
 
+- Plugin SDK: mark remaining legacy alias exports and diffs tool/config aliases with deprecation metadata, and add a guard so future legacy alias comments require `@deprecated` tags. Thanks @vincentkoc.
 - Channels: add Yuanbao channel docs entrance so the Tencent Yuanbao bot appears in the channel listing and sidebar navigation. (#73443) Thanks @loongfay.
 - Active Memory: add optional per-conversation `allowedChatIds` and `deniedChatIds` filters so operators can enable recall only for selected direct, group, or channel conversations while keeping broad sessions skipped. (#67977) Thanks @quengh.
 - Active Memory: return bounded partial recall summaries when the hidden memory sub-agent times out, including the default temporary-transcript path, so useful recovered context is not discarded. (#73219) Thanks @joeykrug.

 ### Fixes
 
+- MCP/plugins: stringify non-array plugin tool results with chat-content coercion instead of default object stringification, so MCP callers receive useful JSON/text content from plugin tools. Thanks @vincentkoc.
 - Channels/Discord: remove Discord-owned queued-run timeout replies through the shared channel lifecycle queue while preserving message ordering and compatibility timeout constants, so long Discord turns stay governed by session/tool/runtime lifecycle instead of channel fallback errors. Thanks @codexGW.
 - Agents/tools: clamp `process.poll` waits to 30 seconds, advertise that cap in the tool schema, and honor abort signals while waiting, so long command polls cannot pin agent responsiveness after cancellation. Thanks @vincentkoc.
 - Plugin SDK: add tracked Discord component-message helpers and a Telegram account-resolution compatibility facade, so existing plugins using those subpaths resolve while new plugins stay on generic channel SDK contracts. Thanks @vincentkoc.
