Samba tells you what the latest stable version is here (at the moment):

https://download.samba.org/pub/samba/LATEST-IS-SAMBA-4.8.3

So you could write a script something like this to check it:

#!/bin/bash

# Get present Samba version
version=$(smbd -V | awk '{print $2}' | awk -F '-' '{print $1}')

url="https://download.samba.org/pub/samba/LATEST-IS-$version"

if curl -f ${url} >/dev/null 2>&1; then
  echo "Using latest version"
else
  echo "New version available"
fi

exit 0
