 - ACP/plugins: add an explicit default-off ACPX plugin-tools MCP bridge config, document the trust boundary, and harden the built-in bridge packaging/logging path so global installs and stdio MCP sessions work reliably. (#56867) Thanks @joe2643.
 - Docs/zh-CN: add a Chinese Diffs tool page so Chinese readers can access the full Diffs viewer, file-rendering, security, and troubleshooting docs. (#40773) Thanks @elliotllliu.
 - Docs/zh-CN: align the Chinese Diffs tool page with the current English source and generated translation metadata. Thanks @gumadeiras.
+- Agents/LLM: add a configurable idle-stream timeout for embedded runner requests so stalled model streams abort cleanly instead of hanging until the broader run timeout fires. (#55072) Thanks @liuy.
