Updates to GNOME and GNOME Software
Several major changes related to the GNOME desktop environment have been included in Fedora 21. These changes include updating GNOME to version 3.12, many improvements to the GNOME Software application installer, and support for the Wayland display server. See https://fedoraproject.org/wiki/Documentation_Desktop_Beat for details. (NOTE: xref)
Workstation Defaults
Fedora workstation by default enables a captive portal detection method that periodically requests known content from a trusted Fedora server.
Terminal Improvements
The default theme has been changed to improve visual integration with the rest of the desktop.
Users configuring their own profiles will welcome the return of background transparency.
Developers and administrators alike use a lot of terminal sessions. A new search provider for gnome-shell integrates with gnome-terminal to make finding the right session quick and easy. Just type into the overview to match running processes, ssh sessions, and more.
