This release also includes LibreOffice 4.4, which has seen a lot of user-interface love and tweaks. LibreOffice 4.4 offers a far more streamlined interface than its predecessors.

Canonical's official announcement also notes that Ubuntu 15.04 forms the base for the software running on the currently available BQ Aquarius E4.5 "and in due course on the Meizu MX4." Ubuntu 15.04 software will be delivered to those BQ Aquarius phones in the next few weeks.
For the developers out there
Canonical is clearly focusing on developers and cloud servers with Vivid Vervet, just as the Fedora project did with its Fedora.next initiative. Its Ubuntu 15.04 announcement touts just how Ubuntu is beloved by developers and available on laptops like the Dell XPS 13 Developer Edition and M3800 Developer Edition.
Vervet sees the Ubuntu Developer Tools Centre becoming "Ubuntu Make." It's a system for easily installing isolated development environments — like the Android NDK and SDK, Firefox Developer Edition, and many other platforms — with a single command. Like Fedora's Developer Assistant, it's designed to help developers get up and running quickly and easily.
Ubuntu 15.04 also brings the Snappy Ubuntu Core, a small-and-secure build of Ubuntu optimized for Internet of Things devices and cloud images.
But little of that matters to everyday Linux users. If you're on the desktop version of Ubuntu, feel free to stick with the current long-term support release of the operating system if the new applications menus and other tweaks fail to tickle your fancy. That's what LTS releases are for, after all.
