You can check todays upload. We also switched to a new spacing model for 
cjk, using penalized glue so a bit more efficient. It should behave the 
same but made solving thsi space issue a bit easier.

There is also some experimental stuff. We already have xmath (more math 
functions), xcomplex (complex numbers), xdecimal (high precision) and 
posit (floats that fit into so called halfwords). Out of curiosity, to 
this repertoire we added xinterval:

\starttext

\startluacode
     local a = xinterval.new(123)
     local b = xinterval.new(456)
     context(a)
     context.par()
     context(b)
     context.par()
     context(a + b)
     context.par()
     context(a / b)
     context.par()
     context(xinterval.mid(xinterval.sqrt(a+b^2)))
     context.par()
\stopluacode

\stoptext

but ... Mikael and I wonder about applications and useability and can't 
come up with real examples.
