Upgrading Wings is a painless process and should take less than a minute to complete.
First, download the updated wings binary into
curl -L -o /usr/local/bin/wings https://github.com/pterodactyl/wings/releases/download/v1.1.1/wings_linux_amd64 chmod u+x /usr/local/bin/wings
Finally, restart the wings process. Your running servers will not be affected and any open connections to the instance will re-connect automatically.
systemctl restart wings
