hmm runs ok here ... but as i removed some old iwona stuff from type-otf 
after our mail exchange i'll make a new beta; also math is not defined 
in the typescript but in a lfg file

subtle difference:

\setupcaptions[numberstopper={:}]
\starttext
\placefigure{title}{\framed{bla}}
\stoptext

all stopper, separator etc things are now more explicit as we have more 
control

as i never used citations i don't know what you expect ... best ask 
Thomas what you should expect ... anyway, i'll make a template for the 
xml approach which is more fun

hm, i get a pdf file with

čšž čšž

so what happens at your end?

weird indeed, must be something basis as

$$111111111111111111111111111111111111111111111111111111111111111111111111111111\normalreqno{!!}$$

also has it .. taco just confirmed that it must be something in luatex 
itself

probably because \type has no strut in mkiv ... maybe it should have

hey, it's spec, no bug (as left is short for raggedleft)

just omit the align=left (was not handled in mkii)

also, commands starting with \latex behave unpredictable in mkiv due to 
luigis compatibility mode

sure, boldmath is now done differently: we have either unicode bold or 
full bold and full bold has never been checked (keep in mind that in 
unicode not all symbols have a bold variant

interesting, i need to look into that

hm, probably not the only difference as we do math differently

magic to me, but we can look into bib mess stuff later

you may make a tracker of this

looks like a mkii problem

to warn me of a slower run and some potentially big extra file

well, now *i* need fresh air -)
