As the config changes we actively cherry picked away in 5.0.6 it didn't get a mention. As it fixes the main bug that people report, I thought it deserved a mention. I've added it to the features.

So I've made a couple more small changes, but overall I think these Release Notes are good to go.

However, I'm rather confused by the entry

One new model has been added to SasView since v5.0.6 was released:

[spin_structure_ferromagnets_3D](https://marketplace.sasview.org/models/140/) SANS in bulk ferromagnets by @stellhorn in https://github.com/SasView/sasmodels/pull/592

I've added the Marketplace link, but I don't see this model in RC2. Was RC2 built with sasmodels 1.0.8?

Is the spin_structure_ferromagnets_3D model supposed to be a new 'library' model in 6.0.0 or does the text 'One new model has been added to SasView since v5.0.6 was released:' need to be removed?

I'll update this - it's called micromagnetic_FF_3D in sasmodels, not spin_structure_ferromagnets_3D.
