Hi Hans,
Thanks for having fixed the behavior of the prime in the latest beta release (ConTeXt version 2017.05.15 21:48).
However, as you may see in the two attached PDF files, the result is still incorrect when one types for example $f_2’’(x)$, which should give the same result as $f’’_2(x)$.
The correct behaviour is that obtained with mkii. Indeed one can circumvent the behaviour of the latest beta release of mkiv by using tricks such as the ones in the example code below, but this should be avoided in my opinion.
The following PDF have been obtained with mkii and mkiv with the following example code.
Best regards: OK
%%% begin derivatives-prime.tex
\starttext
\startformula
f''_{2}(x) = f_{2}''(x) = f^{''}_{2}(x) = f_{2}^{''}(x) % = f^{{}^{''}}_{2}(x)
\stopformula
As one may see the result of \type{f_{2}''(x) = } $f_{2}''(x)$ is not correct in \type{mkiv}.
The following positions of the superscripts \type{(3)} are correct both in \type{mkii} and in \type{mkiv}.
\startformula
f^{(3)}_{2}(x) = f_{2}^{(3)}(x)
\stopformula
\stoptext
%%% end derivatives-prime.tex

If you are using the STIX 2 fonts (http://www.stixfonts.org <http://www.stixfonts.org/>) and my example below you get a somewhat strange behaviour of primes that is pretty obvious. I think the issues should be fixed. By the way the issue seems to depend to some extend on the fonts. Using Lucida by \setupbodyfont[lucidaot] it is not that obvious but still present. Using Latin Modern it seems that the spacing between the primes changes between f'' and f^{''}. Cambria seems to show that behaviour (like Latin Modern), too, but less obvious.

Now, the bad is that when we use a superscript with a smashed virtual characters we end up in script choice mess with primes being one step too small. So, I decided to follow a different route and extend luatex with a sizeless super/subscript feature so that we can handle such weird cases (there might be more). This also means that the primes get larger. I only use the text size prime and scale that down for the other sizes i.e. no stty for primes as they are such a mess) but we can live with that. The good news is that it gets better but the bad news is that you have to wait till we release luatex 1.0.5 (planned for the ctx meeting but we might do an intermediate garden release anyway). btw, with \frac you get cramped styles and these have different positioning. Such is life.

I haven't followed the thread carefully, but there is nothing special in \frac. The likely cause is prime is misplaced in cramped style or similar and similar misplacement will happen whenever that style is used. I would be weary of using {... \over ...}.
