# warning
Due to the partial rollout of Qt 5.4 packages depending on Qt5 that
are not covered by the daily builds might be not-installable if they
require a part of Qt that has not yet been made available or they link
against private API. Former will eventually be resolved once a full
5.4 stack is used.

# changes
- Qt 5.4 is used for all builds
- ISO now uses a different repository with some auto-QA applied to
prevent ever so terrible breakage on updates
- SDDM now runs on tty1 apparently
- kde4breeze once more establishes proper theme convergence between
qt4 and qt5 on first login (やった!)

# errata
- plasmashell-kwin startup continues to cause trouble
- sometimes plasmashell doesn't start on login (or rather it doesn't
display anything) due to kscreen changes
  -- to work around this use krunner (alt+space) and run
     killall plasmashell
     plasmashell

# 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)
