Greasemonkey, the addon? I think that you get notices when a new version is available. You decide whether or not you want to update it.
Or do you mean Greasemonkey scripts? It depends on the script. In some cases, the scripts will notify you when there is a new version, but you will still have to do something things to install the new version.
