+## Upgrading
+
+v0.2.10 is a one-time bridge release. It publishes both the complete Windows ZIP and the legacy `update` ZIP so v0.2.6–v0.2.9 can upgrade to v0.2.10 in the app. Starting with v0.2.11, only the complete ZIP is published; clients already on v0.2.10 can consume it and jump directly across intermediate releases.
+
+If you are running v0.2.5 or earlier, perform one manual migration: exit EasyCLIProxyAPI, download the latest complete Windows ZIP for your architecture, then copy the contents of its top-level directory over the existing installation directory. Do not delete the existing directory first; user data such as `config.toml`, `oauth`, and `cpa-core/config.yaml` will remain in place. After launching the new version, later releases can use in-app automatic updates.

+## 升级
+
+v0.2.10 是一次性桥接版本：它会同时发布完整 Windows ZIP 和兼容旧客户端的 `update` ZIP，使 v0.2.6–v0.2.9 可以通过应用内更新升级到 v0.2.10。v0.2.11 起只发布完整 ZIP；已升级到 v0.2.10 的客户端可以识别完整包并跨过多个中间版本直接升级。
+
+如果当前版本是 v0.2.5 或更早版本，请执行一次手动迁移：退出 EasyCLIProxyAPI，下载最新版对应架构的完整 Windows ZIP，将 ZIP 顶层目录内的内容复制到现有安装目录并覆盖同名文件。不要先删除现有安装目录；`config.toml`、`oauth` 和 `cpa-core/config.yaml` 等用户数据会被保留。启动新版后，后续版本即可继续使用应用内自动升级。
