As a reminder, Ubuntu 15.10 Wily Werewolf is scheduled for release on the 22nd of October 2015.
Despite the fact that Canonical has been working a lot at its Unity 8 DE to get it ready for desktop usage, Unity 7 will still be the default desktop environment of Ubuntu 15.10.
Recently, the Ubuntu developers have decided to replace the regular Unity 7 scrollbars with the ones from GNOME. Except the regular users, a lot of people will not notice the difference.
This is what Will Cooke announced on his Google+ account:
“The original Unity overlay scrollbars were designed to maximize the screen real estate available to applications and to minimize otherwise useless chrome. Upstream Gnome now have some nicely designed ones of their own, and so to minimize the maintenance effort of the Unity ones we’ve decided to adopt the Gnome ones for 15.10 onwards. This represents a considerable saving in engineering effort at each release, where we would normally have to spend time making sure the Unity ones work correctly with each new upstream release of Gnome,”
