 - Feishu/Inbound rich-text parsing: preserve `share_chat` payload summaries when available and add explicit parsing for rich-text `code`/`code_block`/`pre` tags so forwarded and code-heavy messages keep useful context in agent input. (#28591) Thanks @kevinWangSheng.
 - 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.
 - Feishu/Group sender allowlist fallback: add global `channels.feishu.groupSenderAllowFrom` sender authorization for group chats, with per-group `groups.<id>.allowFrom` precedence and regression coverage for allow/block/precedence behavior. (#29174) Thanks @1MoreBuild.
+- Feishu/Docx append/write ordering: insert converted Docx blocks sequentially (single-block creates) so Feishu append/write preserves markdown block order instead of returning shuffled sections in asynchronous batch inserts. (#26172, #26022) Thanks @echoVic.
 - 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.
 - Security/Compaction audit: remove the post-compaction audit injection message. (#28507) Thanks @fuller-stack-dev and @vincentkoc.
 - 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.
