Dear Mohammad Hossein,

The small modification I was talking about has nothing to do with the definition of fonts. In any case here is the file I used to typeset your example (I think you had \startttext instead of \starttext, and also you used \switchtobodyfont instead of \setupbodyfont: however I am not sure whether this is important or not) :

%%%% begin

\definefontfamily     [minionmath] [rm] [Minion Pro]
\definefallbackfamily [minionmath] [mm] [dejavusansmono] [range=digitsextendedarabicindic,offset=digitsnormal]
\definefallbackfamily [minionmath] [mm] [dejavusansmono] [range=digitsextendedarabicindic,offset=digitsbold,tf=style:bold]
\definefontfamily     [minionmath] [mm] [TeX Gyre Pagella Math]

%\switchtobodyfont[minionmath]
\setupbodyfont[minionmath]
\starttext

\startformula
{\tf xyz} xyz {\bf xyz} {\bi xyz}, 
\stopformula

\startformula
2+3+4+5+6+7+8+9+10 = {\bf 2+3+4+5+6+7+8+9+10}
\stopformula

\stoptext

%%%% end

Dear Otared, what is the small modification you mentioned?  Could you share the code you shared to get this output in the latest beta?

Hi Mohammad Hossein,

I don’t get what you expected to obtain in your message, but typesetting your example code (with a small modification) I get the attached PDF file, which seems correct to me.
I am using ConTeXt  version 2017.05.12 22:40 MKIV beta, with LuaTeX version 1.0.4 on MacOS 10.12.5.

Best regards: Otared K.
