# changes
- all builds current again

# errata
- kdepim builds even more out of date as people refuse to bump soversions -.-
- kdeconnect not loading with qt 5.4 (fixed in git) [1]
- there is a mysterious google-contacts-import.log in the home after
first login. apparently created by kaccounts [2]
- discover update feature is broken as it requires qt 5.5, discussed
with Aleix and concluded that it's gonna stay like that since Plasma
5.5 will need Qt 5.5 anyway and we should land that soonishy for the
ISO
