I really like to see things updated as well.

From what I gathered the situation is still blocked by Qt 5.6.1 being 
finalized and entering unstable.

unormal on #debian-qt-kde gathered as much as:

"lisandro told me yesterday that 5.6.1 is planned 6 to 8 weeks after 5.6 
(we're now in week 4 or so) and then IIRC they plan to first upload to 
experimental and then to unstable."

"Target to get Qt 5.6.1 out at the beginning of May"

Thing is while Qt 5 has hefty regressions already that break multiscreen via 
randr completely, such as:

[kwin] [Bug 361704] New: window on external screen disappears when hibernating 
with external screen connected and resuming when it is not connected

which are summarized into

[kwin] [Bug 341497] Segfault in Qt since the (at least) the xcb screen backend 
cannot deal with "no screen" conditions


Qt GUI application disappear or crash when no screens are available

I already read that while Qt 5.6 hopefully fixes these (still not sure), it 
also contains *new* regressions:


So it appears to me right now there are at least some severe issues with the 
foundation Plasma / KF 5 is based on: Qt.

I didn´t read about why Qt/KDE debian team waits for Qt 5.6.1 instead of going 
with Qt 5.6 for unstable, but that may be part of the reason.

If you want to find out in more detail, I suggest you ask on #debian-qt-kde on 

Of course I think the Debian Qt/KDE team can benefit from more helping hands. 
For packaging I think Maxy´s mass-uploading new packages with his scripts and 
other people helping with packaging is working out quite good already. But any 
new packages need user testing then, especially those batch uploaded ones, and 
the Debian bugtracker in regards to Plasma 5 is in a sorry state. On DebConf I 
gathered from Maxy that the Qt/KDE team really appreciate any help with bug 

So or so, nothing of what I write is an official statement of the team. Thats 
just as much as I gathered here and there.

So hopefully beginning of May Qt 5.6.1 will enter experimental, then unstable 
and… then it might go quite quick. I saw Maxy uploading 50+ or even 100+ 
packages a day often enough already :).
