Hello all, I've used ConTeXt MkIV for years to make technical reports. For a new computer I looked for updates of the software and discovered LMTX. I ran it on my latest report and found an error on \completelistofabbreviations, both on win-64 and linux. Context --luatex worked fine. A minimal file based on the wiki examples produced the same error on \completelistoftests: \definesynonyms[test][tests][\infull] \setupsynonyms[test][criterium=all] \test{ITU}{International Telecommunication Union} \test{MID}{Maritime Identification Digit} \test{Ch}{Switzerland} \starttext The \ITU\ is an organisation in \infull{Ch} % \subject{Short is nice} % \placelistoftests \completelistoftests \stoptext Did something change, or did I find a bug?
