+## 已知问题
+
+1. (示例)版本号管理不规范
+   - 版本号直接写在环境变量中，容易出错
+   - 多处维护版本号，可能不一致
+
+## 解决方案
+
+1. (示例)将版本号管理从 `.env.local` 迁移到 `package.json`
+   - 统一从 `package.json` 读取版本号
+   - 使用 IIFE 优雅处理版本号获取逻辑
+   - 保持向后兼容，支持环境变量覆盖
+
+## 改动收益
+
+1. (示例)更规范的版本管理
+   - 统一从 `package.json` 读取
+   - 保持与 npm 生态一致
+   - 减少人为错误
+
+## 具体改动
+
+1. （示例）`blog.config.js`
+   - 移除原有的静态版本号配置
+   - 在文件末尾添加动态版本号获取逻辑
+   - 保持向后兼容，优先使用环境变量
+   - 添加错误处理和默认值
+
+## 测试确认

+- [x] 本地开发环境测试通过
+- [x] 生产环境构建测试通过

+## Environment Variables
+
+NotionNext uses environment variables for configuration. To set up your development environment:
+
+1. Copy `.env.example` to `.env.local`
+2. Fill in the required values in `.env.local`
+3. Never commit `.env.local` to version control
+
+The configuration priority is:
+1. Notion Config Table (highest)
+2. Environment Variables
+3. blog.config.js (lowest)
