To write blackboard math, the syntax was

$\blackboard{N}$

${\blackboard N}$

. Is this indented? (the old way is a bit easier to use)

Secondly, I want to address the blackboard font. Try out

\starttext ${\blackboard NR}$ \stoptext

This looks different then in the past. It doesn't have serifs. It looks like the wrong font, like sans. Is this a bug? To me it looks awful, honestly. It doesn't fit the rest of the math font at all. Basically we're talking alphabets here and in opentype math fonts these are complete alphabets. So, \blackboard is an alphabet switch. You can use \mathbb{X} as an argument variant.

About the shapes ... those are the ones that come with the font (and imo when blackboard is indeed that what gets drawn on blackboard serifs probaby make not that much sense, but that's personal).
