Server in 1.21.5 > Update 1.21.6

[Nathaan]

Hello, 

First this is my first post on the forum I'm French, so I might make mistakes when I write.

I recently bought a server to play with my friends today. I've seen that there is an update
        If I do it, should I have to restart the server or go into the server settings and do something?

Stop server, update, then start server
