第29章 MCP团队协作与管理
29.1 MCP服务器版本管理
29.1.1 版本策略
MCP服务器的版本管理遵循语义版本化（Semantic Versioning）：MAJOR.MINOR.PATCH
- MAJOR: 不兼容的API变更（需要客户端更新）
- MINOR: 新增功能（向后兼容）
- PATCH: 错误修复（向后兼容）

29.1.3 版本发布流程
1. 开发阶段（Development）
├─ 在 develop 分支上开发新功能
├─ 代码审查和测试
└─ 准备发布
2. 发布准备（Release Preparation）
├─ 创建 release 分支
├─ 更新版本号
├─ 更新 CHANGELOG
└─ 最后测试
3. 发布（Release）
├─ 合并到 main 分支
├─ 创建 git tag
├─ 发布到 package manager
└─ 发送通知
4. 后期支持（Post-Release）
├─ 监控问题
├─ 紧急修复
└─ 准备下一个版本
