 - 默认 PPTX 导出统一走本地 patched WASM（单一真源 `editor/neo-ppt/assets/pptd_wasm_bg-DPPWdROu.wasm`）
 - 本地编辑器关闭分享 / 云盘 / Google Drive 入口；拦截相关云端与 Google API 请求
 - 移除旧 iframe 壳（`app.js` / `styles.css`）、废弃的 `export_host.html` 与未接线的浏览器顶栏导出胶水
+- **务必升级**：本版本已彻底本地化，编辑与导出均走本地 neo-ppt 镜像 + patched WASM，不再经过官方云端导出链路，也不会再触发「官方导出需要签名」问题；请运行 `npx open-kimi-ppt-skill@latest install -y`（或交互选择目标目录）重新安装，将完全本地化的资源同步到已安装目录。
 
 ### 修复
 

CHANGELOG_EN.md

@@ -17,6 +17,7 @@ This project follows [Semantic Versioning](https://semver.org/).
 - Default PPTX export uses the local patched WASM (single source: `editor/neo-ppt/assets/pptd_wasm_bg-DPPWdROu.wasm`)
 - Local editor hides share / cloud / Google Drive entry points and blocks related cloud/Google API calls
 - Removed the old iframe shell (`app.js` / `styles.css`), deprecated `export_host.html`, and unused browser top-bar export glue
+- **Be sure to upgrade**: this release is fully localized — editing and export now run entirely on the local neo-ppt mirror + patched WASM instead of the official cloud export pipeline, so the "official export requires signature" issue no longer occurs. Run `npx open-kimi-ppt-skill@latest install -y` (or pick a target directory interactively) to reinstall and sync the fully localized resources into your installed directory.
