 ## 变更日志
+- v1.2.14  更新检测修复：Release 检查优先走 GitHub latest 页面跳转并回退 API，避开匿名 API 403 限流；同时把更新时间与可用版本写回本地缓存，减少重复请求
 - v1.2.13  粘贴根因修复：移除对 ink-text-input 的关键依赖路径，改用本地稳定输入组件；多段 paste 不再因 React 受控输入闭包滞后而丢失前缀
 - v1.2.12  密钥完整性修复：表单为长密钥显示首尾摘要与长度，拦截空格/换行损坏，并要求二次确认后再保存，避免 WSL/终端粘贴异常时把截断密钥静默写盘
 - v1.2.11  更新体验修复：更新确认页展示准备/下载/替换阶段与下载进度，完成后短暂停留再退出；Linux/macOS 前台下载后原地替换，避免“确认后直接弹出”却看不见过程
