The awesome Xfce DE had a stable release yesterday. Version 4.12.
Xfce 4.12 is now available in Fedora Rawhide. All the core packages and most of the plugins are now built and ready to be tested. Ideally, they should land in tonight's rawhide live images.
If there are no show stoppers, we will build the packages for Fedora 22 the coming week and see if we can get the change approved in time.One bug we are already aware of is with respect to mousepad (https://bugzilla.redhat.com/show_bug.cgi?id=1197504). Other than this, nothing seems broken (at least as far as I can tell).
Give Xfce 4.12 a spin on Rawhide. The more testing we get, the better it would be for stable releases.
