Hi Hans,
I noticed that recently a discrepancy in the way the prime is positioned in the presence of an index as in $f'_n$ or $f_n'$ (please see the attached PDF). However the positioning is correct in expressions such as $u^k_n$.
The problem shows up only in mkiv, and as far as I can say the differnece between the results in mkii and mkiv appeared recently (unfortunately I can't say when…).
%%%% begin minimal-example.tex
\starttext
\startbuffer[math]
If for $n \geq 1$ we consider $f_{n} : {\Bbb R} \longrightarrow {\Bbb R}$ a real valued function, and $u_{n} : {\Bbb Z} \longrightarrow {\Bbb Z}$ then we denote
\startformula
f'_{n}(x) := \lim_{h\to 0}{f_{n}(x + h) - f_{n}(x) \over h}\qquad\mbox{and}\quad u^k_{n} := u_{n}(k)
\stopformula
\stopbuffer
\getbuffer[math]
\switchtobodyfont[times]
\getbuffer[math]
\switchtobodyfont[palatino]
\getbuffer[math]
\stoptext
%%%% end minimal-example.tex

something got lost when cleaning up the code ... fixed (but we have
smaller primes .. i'll make a large option one day but rather wait till
there is a trivial extension to luatex (that i need to discuss with taco)

Thanks Hans: I did some testing with several fonts and situations, and everything is perfect.
Best regards: OK
