To retrieve your server version, in your server's terminal, run:
cat $(npm root -g)/lamassu-server/package.json | grep "lamassu-server@"
You'll see an output similar to that below:
root@lamassu-cryptomat:~# cat $(npm root -g)/lamassu-server/package.json | grep "lamassu-server@"
In this case, your present server/admin version is 7.4.10.
You may view the latest server version on our Github: https://github.com/lamassu/lamassu-server/releases
