# changes
- kio CI repaired
- kdeconnect CI repaired
- muon CI repaired
- kwin shouldn't crash anymore when entering the live session
- kde telepathy requires installation of signon-plugin-password so it
works as expected (your's truly forgot to push the fix for that, fixed
for next week)
- dolphin now correctly pulls in the konsole kpart4
- cantor is being integrated correctly (sudo apt install cantor)
- the previous graphics glitches in virtual machines should be gone entirely now

# errata
- screenlocker still starting after 1 minute, fix applied and should
be in next week's ISO
- mouse cursor still bugs out on parts of the desktop (under
investigation still)

# long standing errata
- all issues affecting Kubuntu 15.04, nothing major known right now
- 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.
