No, this works perfectly fine with the open source version for up to 50
agents.

That feature allows you to update the HQ agent on your different servers
without having to touch all of them individually. With the open source
edition an agent update means you have to access all servers (via
ssh/remote desktop/whatever), stop the agent, update its installation
and start it again. With the enterprise edition you can do that
centralized via the server's user interface. Much easier, especially
with larger installations.
HTH.
