# changes
- kdenlive is now correctly installable
- kate plasmoid being broken and showing up by default issue resolved
- clipboard should be working as expected [1]
- adding default widgets shouldn't crash the shell anymore

# errata
- all issues affecting Kubuntu 15.04 also affect the ISO (which among
other things includes a slightly bugged out installer, best only
install using en_US)
- the ISO is rolled using the CI landing PPA due to stabilization
blockage from missing bluez5. this in turn means that upgrades
potentially won't work or break half way through as the underlying PPA
breaks ever so often.
- plasma wallpaper thumbnailing is broken; cause unknown

# virtual machines
virtual machines have a bit of trouble with the graphics. At least
with virtualbox you can workaround the problem by temporarily
switching to a different TTY (right-ctrl+f2 -> right-ctrl+f1)
