Hi,
I uploaded a new version. Apart from a few fixes / extensions already
mentioned here (or known to those who wanted it) the main changes are in
the math goodie files (work in progress, we will clean them up later) as
part of improving the rendering of math.
Something is wrong with the placement of limits around an integral with
NeoEuler:
...
\usetypescriptfile[euler]
\definetypeface[mainfont][rm][specserif][CharisSil][default]
\definetypeface[mainfont][mm][math] [eulernova][default]
\definetypeface[mainfont][tt][mono] [dejavu][default] [rscale=0.8,
features=none]
...
\setupbodyfont[mainfont,10pt]
\starttext
\startTEXpage[offset=1mm]
   $\displaystyle \int_{0}^{1} f(x) dx$
\stopTEXpage
\stoptext
gives the attached result.
This is because the integral "sits wrong" in its boundingbox. Almost
all fonts have the glyph centered around the math axis, but there are
a few that doesn't. In euler-math.lfg, add the tweak
{
tweak = "fixoldschool",
},
This fixes the issue with eulernova, but not with pagellaovereuler.

pagellaovereuler uses euler-with-pagella-math as a goodie file, but that is
missing from the distribution. (I simply copied euler-math.lfg for my use
case).

With tweak=fixoldschool, \startcases doesn't work correctly (see attached):
\usetypescriptfile[euler]
\definetypeface[mainfont][rm][specserif][CharisSil][default]
\definetypeface[mainfont][mm][math] [eulernova][default]
\definetypeface[mainfont][tt][mono] [dejavu][default] [rscale=0.8,
features=none]
...
\setupbodyfont[mainfont,10pt]
\starttext
\startTEXpage[offset=1mm]
   \startformula
     \startcases
       \NC A \NC B \NR
       \NC C \NC D \NR
     \stopcases
   \stopformula
\stopTEXpage
\stoptext
Looks like some older experimental value is wrong:
parameters = {
--             DelimiterPercent    =  901,
             DelimiterShortfall  =  500,
         },
(that whole lfg is a todo)
Thanks. This fixes the delimiters.
