Note that the new Bluetooth support is being held back.

Kubuntu 15.04, aka Vivid Vervet, was released last week. With this release it has become the first major distro to ship Plasma 5 as the default desktop environment.
Fast forward to 2014 and Kubuntu turned out to be a totally different OS. I have been running it on one of my production systems since 14.04. It’s extremely stable, polished and offers a great experience.
Kubuntu features one of the best notification systems in the Linux world.
Kubuntu 15.04 is undoubtedly the best Plasma 5 desktop so far, for the simple fact that this is the first distro to ship with it. Since Kubuntu offers a vanilla Plasma experience, you can enjoy what KDE developers originally developed without it being heavily patched or modified. Well, modification can be good in some cases where a particular may not gel very well with the distro.
In a nutshell, I found Kubuntu 15.04 to move consistently on the path of improvement, getting better with each release. If you are hesitant about Kubuntu due to a previous release, let me tell you that a lot of water has flowed under the bridge since. It’s a totally different Kubuntu.
Try it out and you will be surprised with what you have been missing until now.
And that is even before Plasma 5.3
Softpedia was one of the first to break the news, with the headline, “Kubuntu 15.04 Officially Released, Based on Beautiful Plasma 5 Desktop”. They write:
Kubuntu developers don’t usually integrate a custom KDE experience, so Kubuntu is the perfect opportunity to test and see what the developers want to achieve with latest and best of KDE. This is close to what the makers of this great desktop environment are really trying to achieve, so you can easily use Kubuntu as a standard by which any other KDE-powered OS can be judged.
