+##### Why is the new version of Arthas downloaded, but the old version is connected?
+
+For example, the started version of `as.sh/arthas-boot.jar` is 3.5.*, but after connecting, the printed arthas version is 3.4.*.
+
+It may be that the target process has been diagnosed with the old version of arthas before. You can execute `stop` to stop the old version of arthas, and then reuse the new version to attach.

+##### 为什么下载了新版本的Arthas，连接的却是旧版本？
+
+比如启动的 `as.sh/arthas-boot.jar` 版本是3.5.* 的，但是连接上之后，打印的arthas版本是 3.4.* 的。
+
+可能是之前使用旧版本的arthas诊断过目标进程。可以先执行`stop`停止掉旧版本的arthas，再重新使用新版本attach。
