Comment (by iandw.au@…):

 Just for information and not wishing to put on pressure, the KDE
 developers have started to ship KDE Frameworks 5, the new KDE libraries,
 which depend on Qt 5 (https://techbase.kde.org/Schedules/Frameworks).  In
 December they are planning to release a mixed batch of KDE apps (i.e. no
 libraries), which has been dubbed KDE 14.12 (yes, year.month).  Some of
 these apps will have been ported to use Frameworks and Qt 5 and some
 (perhaps most) will still be using KDE 4 libraries and Qt 4.  The releases
 of KDE apps will be named by year and month from then on.

 No doubt the proportion of ported apps will grow over time, as it did with
 the KDE 3 to KDE 4 transition.  Whatever happens, MacPorts will need to
 provide a mix of KDE 4, Qt 4, Frameworks 5 and Qt 5 for some time to come,
 with KDE apps building onto one dependency path or the other.  The good
 news is that this change does not seem to be as "radical" as the KDE 3/4
 change was, from the point of view of applications and API, but it will be
 quite a lot different in its build characteristics - hopefully a lot
 simpler once the changeover has been made.
