I found the RSS- and Atom-feeds of the Github-repository in the source of the releases page. There are special feeds for the last commits, the tags and for the releases. I think, this overture is worth to think about an overhauled update notification. The update process in itself should stay untouched.
Actually the admin can detect the installed version in the admin area and has to check a website (that can change from time to time) for the presence of a newer version. My idea is, to list the atom-feed of the releases (header and date) in the admin area. Maybe only newer versions than the installed because the version string is detectable in the feed, so we can determine it.
<id>tag:…,2008:Repository/60085679/v2.3.7beta2</id> <link rel="alternate" type="text/html" href="/ilosuna/mylittleforum/releases/tag/v2.3.7beta2"/>
That said, I wish to show the up-to-date version anywhere in the admin area or, only for admins at the top of the side- or bottombar.
