# changes
- the ISO is now using the upcoming Kubuntu 15.04 as a base
- the ISO is only available as 64bit moving forward. the 32bit latest
link was removed.
- kdenlive available for manual installation (sudo apt install
kdenlive) - currently segfaulting, should be fixed tomorrow

# 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. hopefully the next ISO fixes this.
- kate plasmoid continues to be busted. apol said he'll re-poke.
- plasma wallpaper thumbnailing is broken; cause unknown
- clipboard is malfunctioning with various applications pending qtbase patching
- widgets crash plasmashell upon plugin loading; cause unknown (e.g.
calculator when drag'n'dropped to desktop)
- lock screen is using the 5.1 wallpaper; 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)
