@@ -24,6 +24,10 @@ rakshasa是一个使用Go语言编写的强大多级代理工具，专为实现*
     - 增加node版本，去掉私钥，无法发起代理等关键操作，适合被控
     - 增加lite版本，在上面版本的基础上，精简cli交互与http代理池，体积缩小2mb
     - 优化节点连接逻辑，并且遍历网卡ip进行net.Dail，解决多网卡下，无法连接的问题
+-  **v0.2.2**  2023-04-08
+    - 增加http_proxy重连逻辑，节点掉线后重连http代理能够正常重连使用
+    - 优化节点重连逻辑
+    - 增加uuid选项，默认uuid使用网卡mac作为随机数种子，进行生成
 
 ## 编译与使用
