 - [x] 支持对```CN2GT```和```CN2GIA```线路的判断，原版[backtrace](https://github.com/zhanghanyun/backtrace)不支持
 - [x] 支持对```CMIN2```和```CMI```线路的判断，原版[backtrace](https://github.com/zhanghanyun/backtrace)不支持
 - [x] 支持对整个回程路由进行线路分析，与原版[backtrace](https://github.com/zhanghanyun/backtrace)仅进行一次判断不同
-- [x] 修复原版[backtrace](https://github.com/zhanghanyun/backtrace)对IPV4地址信息获取时json解析失败依然打印信息的问题
+- [x] 修复原版[backtrace](https://github.com/zhanghanyun/backtrace)对IPV4地址信息获取时json解析失败依然打印信息的问题，本项目忽略错误继续执行路由线路查询
 - [x] 增加对全平台的编译支持，原版[backtrace](https://github.com/zhanghanyun/backtrace)仅支持linux平台的amd64和arm64架构
