When Xshell starts, the following interface pops up, "To continue using this program, you must apply the latest update or use a new version."
This problem is that there is a problem with the version of xshell, which is not the latest version. You need to reinstall the version of xshell.
(Xftp ditto)
1. Uninstall the original Xshell version.
2. Visit the xshell and xftp official websites (the same official website) to download the new version
