I'm not quite sure how to answer your question, BluEcho. All releases are in a sense official. I think the more important distinction is between stable - or finished - and unstable. That's why I wrote this bit in the Wiki which says which parts of Antonia are considered finished at this point and won't change anymore.

I was planning to have both the hands and feet finished by the next release, which will have the version number 0.9.124, but as it looks now, it will just be the hands. By 0.9.125, I should have everything but the head finished.

There will be no changes in the UVs that you need to worry about. When I reshaped the feet, I decided to make some changes to the toecaps that might introduce some stretch. I will try to adjust the UVs for the toecaps - and just the toecaps - appropriately so that the stretch disappears. As far as I know, there are no texture maps for the toecaps yet, so that shouldn't concern anyone. Even if there were, I'd try to do it in a way that wouldn't break existing textures.

That's generally true: if I were to do any further changes on the UVs at this point - and I am not really planning to do that anyway - it would just be small adjustments after reshaping things so that existing textures will still work the way they were supposed to.

-- I'm not mad at you, just Westphalian.
