SSH3 version 0.1.1, with the client available to many platforms.
Note that SSH3 is still experimental. You can SSH3 server using the -url-path command-line argument.
If you run Linux, you can download both the server and client contained in the _linux release archive.
If you don't run Linux, you can still use the SSH3 client by downloading the _clientonly archive corresponding to your OS and architecture and use it to connect to your Linux-based SSH3 server.
It compiles on Windows but arrows and unix-specific terminal characters do not work on classical windows terminal and Powershell.
