 # Change Log
 
+### v1.1.1
+    新特征:
+        1. 扫描进度信息中追加了估算剩余时间信息
+
+    增强：
+        1. 增加默认端口: 1024,6868,8182,9080,9999
+
+    修复:
+        1. 修复使用 `-p xx` 时，不会覆盖默认端口的逻辑问题
+
 ### v1.1.0
     概述:
         主要为自动消除 TCP 无意义的扫描，提升扫描速度

         3. 对位置的错误情况，添加了更详细的错误输出，便于调试
         4. 增强扫描结束后统计的数据显示
         5. 降低了耗时统计的时间单位精确度

+        6. 对端口列表进行去重处理
         7. 对端口随机后还是会优先探测常用端口列表 (Targets:Ports 则常用端口交集),
            从而提高自动放弃扫描机制可靠性
