Confused with Index of /repositories/home:/wolfi323:/branches:/KDE:/Frameworks5/openSUSE_Factory rep

I am using the latest tumbleweed iso (10th May) and kde5 from the above repo (so as to keep kd4).

Confused today when I did an update as there are now a number of kde4 application rpms included in this repo?

Yes.
I moved all KDE4 applications that got replaced by their KF5 releases upstream in the 15.04 release (and will therefore be replaced with the next Tumbleweed snapshot) to my repo.
I did this so you can keep the KDE4 based version as well, if you want to.
All of them are available as KF5 versions in my repo too, but with a ‘5’ in the name as before.

Btw, I branched them from KDE:Current, so those are the latest openSUSE KDE4 packages.

Thanks very much for explaining.
