[x265] Max TU Size

Quick question about the max TU size.
It used to be something like
tuQTMaxLog2Size = MIN(5, maxLog2CUSize)

Now it is simply maxLog2CUSize -1.
It makes no difference for 64x64 CTU but it tends to worsen quality (or increase bitrate) for smaller CTU sizes.

Is this a wanted behaviour and if so, why?
