I've just upgraded to the latest and greatest version and found that my previous fixes for a bibliography quirk no longer work.
Taco, do you have any ideas on why this is failing again?
Probably that fix was patching an internal macro the handling of which has changed in the context core. Just a guess, though.
I have no time today to delve into this, sorry. As I wrote to Aditya last week, you will probably have to wait until January.
Best wishes, Taco
