While the first Beta of Ubuntu GNOME 15.04 brought the GNOME Shell 3.14.3 user interface, an experimental Wayland session, and updated Ubiquity slideshow and desktop wallpaper, the second Beta includes no new features, only bug fixes. It is still based on the GNOME 3.14 desktop environment, and various core components have been updated to version 3.14.1 or 3.14.2.
