# changes
- this ISO uses the Plasma/5.2 branch for pre-release testing
- all new 5.2 bits are integrated

# errata
- kde4breeze is not run; fixed in git

# 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)
