Naturally, GNOME is getting an upgrade, with Fedora 23 containing a preview of the upcoming GNOME 3.18 release, which is easier to use than ever. There are also many enhancements on the way, such as:
Improvements to next-generation graphics stack Wayland, preparing it to be the default graphical server in a future release. This includes mixed HiDPI support, to provide a better experience when moving apps between HiDPI and non-HiDPI monitors
Support for ambient backlight drivers, so brightness responds to the environment on laptops with the required hardware
The Software application is smarter about metered Internet connections, and can now update system firmware
Refreshed support for Google APIs to provide access to user data through GNOME apps (including Google Drive integration)
