gamut - reduce artefacts from blue sky

Hi there,
i used to work on RT 5.8 and found this button “gamut - reduce artefacts from blue sky” under Wavelet very helpful. With this function i often could skip the noise reduction.
Now under dev-2711, i cannot find it anymore… has it been moved or just removed?

And, if i am allowed, a second question:
all the settings and profiles i put under 5.8 were gone, when i opened dev2711. I manually had to copy them from the “old” version to the new one. Is this the intended way to handle this?

thanks for a short explanation
