1. 新增排序
|
||||
2. 新增网卡自定义掩码
|
||||
3. 新增网卡端口转发
|
||||
4. 新增托盘置顶
|
||||
5. 移除linker.service，将windows service内置
|
||||
6. windows下，需要重新卸载安装服务
|
||||
7. 先更新所有客户端，再更新服务端(先更新服务端会获取不到客户端列表)
|
||||
1. UDP端口映射连接(无ssl加密)
|
||||
2. UDP打洞，纯净版(无ssl加密)
|
||||
3. 如果当前版本小于v1.2.0.4，则windows下需要重新卸载安装服务
|
||||
4. 先更新所有客户端，再更新服务端(先更新服务端会获取不到客户端列表)
|
||||
5. 用不上无加密UDP打洞的可以不更新
