Some of the changes should be reported to Hans (of general interest) but I didn't get around doing this, but was planning to do that in the next few weeks.
Ok, please let us know when you'll have it done (or if you cannot).
but the stable is unlikely to get synced since ConTeXt beta require luatex 0.65.x at least.
Sure, I think the code is OK as it is anyway, people playing with fancy font requiring a cutting-edge code will update to a cutting-edge luatex...
Thank you, -- Elie
