I am testing now this cupdater script and i think there is one small thing what i like that is available in this cupdater.
now i test on one site but what if i have 10 sites. Not all the sites have the same third party components modules and plugins.
i like it if there is in the notification mail an extra line where i can see that there is an update available for the name of the website.
Than it is easier to look which sites have updates.
