Don't be or let me clear this a bit. The KIO restructuring and moving has 
nothing to do with the KDE Platform (kdelibs) 4 and Qt4 stuff. It's all about 
KDE Frameworks 5 and Qt5 so don't be confused or worry as long as you don't 
use Qt5 and KF5 based software.

And here I'd like to bring up another topic. Not _that_ important but as I 
think KDE software on Mac might become more popular in the future (due to your 
great work) and the above email shows it quite cleary as well we should start 
to think about it in here as well. It's about "what is KDE?". You might 
probably know that we did a rebranding years ago and "KDE" is now just the 
community, not the software.

And the above email of Ian shows it quite good. There you talk (but not just 
you!) about "KDE 4.12" and "KDE 4.13" and "apps" and co. Ironically most 
people who still use the term "KDE" for our software think about it as the 
"desktop environment" or just "desktop" which is Plasma (by KDE) and doesn't 
make much sense on Mac.

So what do we have:
- There is the KDE Platform (monolithic kdelibs) based on Qt4 which is 
features frozen since around 4.9 (but still, the version number goes up 
together with the KDE Apps and we're now at 4.13.1 although the Platform 
doesn't get new features). The future of the Platform are the KDE Frameworks 5 
based on Qt5 and modularized so that developer can just take e.g. Karchive or 
KConfig and don't need to use all of kdelibs if they want to use our great 
- Then we have the workspaces which are known as Plasma. The feature 
development of Plasma based on KDE Platform 4 and Qt4 was stopped at 4.11 and 
is since then in LTS.
- And then we have the KDE Applications (or better "some KDE apps") that are 
or were released together with the Platform and workspaces. They still get new 
features and there will probably be another 4.14 or even 4.15 release which is 
not yet decided.
- And beneath this we (KDE) has even more software like e.g. Kdenlive, 
KMyMoney, Digikam, Amarok, Rkward, Konversation, etc. which is releases 
completely independent.

So of the above for the Mac everyhing is interesting expect of the workspace 
aka Plasma.

Hope this makes is a bit more clear and probably gives some hints why we 
decided to change the meaning of "KDE". And take a look at the dot.kde.org to 
see the releases of the last years. There was never a "KDE 4.x.y" ;-). But 
people need to understand that they can use parts of the great KDE Frameworks 
and that most of the KDE Applications work great even in the Gnome shell, xfce 
and Co and even on Windows, Android and Mac but who am I telling this ;-).
