Full instructions to upgrade from 14.04 LTS

Choose Stable Plasma 4 or Tech Preview of Plasma 5

Plasma 4 is our recommended stable offering and what you get
from the default download, but is now in maintenance mode.
It runs the software you are familiar with and will be getting updates and bugfixes but not new
features from now on.
Plasma 5. The next generation of KDE Software is still a work in progress. You can test it and install
it from the Kubuntu Plasma 5 image but beware it will remove your stable software. We love testers but no support is offered. If there are problems you may need to reinstall to revert back to Plasma 4.
