I think I have replied only to Gonçalo and not the entire list. Sorry if
the message is repeated,  but I do not know exactly how this is used.

I have noticed that in some of my photos profiled noise reduction is
applied much stronger than before (even in low isos), loosing details. I
mentioned this to the developers, but they have told me that there was no
change in the code of profiled noise reduction. So perhaps changes in
demosaicing code?. I don't know, it is somewhat confusing to me because
apparently in some photos I lose more details than others. First I thought
it could be related to having the OpenCL enabled, but I'm not sure and I
can not find patterns about  when this issue is more noticeable.
