Hello,
About the refracted background, I found the change here: https://github.com/YafaRay/Core/commit/0451d94
The reason for the change was that, when using refracted background, volumes were still rendering it because it was still used for the raytracing process. The only way I found to solve that problem was to remove the background from the raytracing when transparent refracted background was used.
If needed we can add this to the feature requests, for further study (would not be easy to do). However, I have a question: in what situation(s) you would want a transparent refraction of the background but still keep the background reflection?
About the dispersion, I don't remember having changed that. However there were some reports in the bugtracker in the past about it being "too strong". Probably another developer changed it a long time ago to make it more "physically correct"?
More info here:

Please will you let me know what is the last version where the effect is as you had before? Maybe I could double check...
