So stelle ich mir ein einfaches Update vor

einfach "Automatsich aktualisieren" klicken und schon wirds gemacht !

2.7.1, the first 2.7 maintenance release, is now available.  2.7.1 fixes 68 tickets.  You can automatically upgrade from 2.7 to 2.7.1 via the Tools->Upgrade menu, or you can download the package and upgrade manually.
