Are you sure these are the same settings that you used with beta.36?

To be frank, I can't imagine you used PNG output when working with 
beta.36 - because with PNG files, it doesn't matter what encoding gamma 
(derived from File_Gamma) is used: They will only seem to match the 
render preview if you set the proper Display_Gamma for your system 
(provided the image viewer does a proper job).


Anyway, a beta.37a is just about to be released that will restore 
beta.36 gamma behavior.
