Hi, stoneage i have several aclarations and several questions:
First as for the qt bindings, did you create user-config.py and set this variable (WITH_YF_QT='true') in it?
that leads to clarificate that the qt gui you are using is the official one not the one in my branch (cos it wasn't built) so the middle mouse click panning and the <ctrl+mouse wheel> zooming wont be available neither the layout change the timming showing in hours, mins, or seconds (depending on rendering length) nor the black background for renders or the auto-resize feature fix.
Now, to use the ies feature you need to create a folder called iesFiles inside .blender/scripts/yafaray/ so the path will look like .blender/scripts/yafaray/iesFiles and put there some ies files, in the gui the ies lamp is available when you create a spot lamp, the distance and the angle of the spot are ignored, in the exporter gui you call one of the ies you previously put in the iesFiles folder, by its name without extension (remember this is in development stage so that is faster to test for me cos i have my ies files with names like 1.ies, 2.ies, etc, so i call them as 1,2,3,etc)
the blur strength slider is how wide the blur on the light should be and the resolution parameter is the number of samples for that blur, the soft shadows toggle sets the light in sampled mode (like area or sphere lights) and the samples parameter... well the samples for the sampled light (doh! hehe)
As for the automatic thread number detection, to activate it set threads to 0 (Zero

)
Also i wanted to tell you about the instant render is a test to use the cli script inside blender that was a lobo_nz idea but is not really ment for it to be used from the menu but from the console
And some extra details:
"use background" button is gone from the settings, instead now each background has its own IBL button or in sunsky's case the skylight button
I added a change in glass, now the photon caustics respond to the glass IOR
The fireflies on glossy and coated glossy should be reduced and the anisotropic mode on glossy doesn't need uv mapping anymore
The bump mapping is now less sensitive to the slider and won't be needing values below 0.001 anymore (hopefully

)
i'll be posting all of the changes as soon as i recall them

(is quite a bit)
As for the problems i think is ok to post them in this thread
Happy rendering...
