The beauty pass is not affected, but as far as I know, the MaterialID, ObjectID and ambient occlusion are
Here are some examples of the same scene rendered in 3.05 (left) and 3.06 (right) :

Yes, there was a bug in the tone mapping of some info passes, which we fixed in 3.06:
We were applying the gamma value of the imager settings for various info passes (like the ID passes, wireframe or AO). The problem with that is that the gamma in the imager settings is applied
on top of the gamma of the camera response curves, i.e. it's usually set to a gamma of around 1. But when you choose the response curve "
Linear/off", you usually have to set the gamma to 2.2 or something similar to compensate the gamma of the display (or to bring it into sRGB colour space).
In other words, depending on the camera response curve, info passes would be tone mapped differently, which of course shouldn't be the case, because the camera response curve isn't applied to info passes. To fix this problem we now
always apply a gamma of 2.2 for the affected info passes and ignore the gamma setting in the imager.
