I re-processed a previous issue of a journal and found that it no longer compiled. It worked fine in versions up to and including 2021.07.23 but fails by version 2021.08.19 19:48. It may have failed a little earlier than this - I don't always refresh every release. The error in the console log is: [...] open source > level 2, order 9, name 'covers/inside-front-cover.tex' tex error > tex error on line 24 in file covers/inside-front-cover.tex: lua error: registered function call [396]: ...-64/tex/texmf-context/tex/context/base/mkxl/anch-pos.lmt:1286: attempt to call a nil value (upvalue 'texgetparstate') stack traceback: ...-64/tex/texmf-context/tex/context/base/mkxl/anch-pos.lmt:1286: in function <...-64/tex/texmf-context/tex/context/base/mkxl/anch-pos.lmt:1262> (...tail calls...) [...] Unfortunately I can't create an MWE any smaller than a project with about 3 sub-directories and half a dozen files. I don't really want to post it all here but happy to send a zip to Hans. (When it works it only creates a two page PDF so 'minimal' in that sense.) Secondly, something a bit specific to Macos also broke for the latest version. Previously I had: \definefont [RPN] [Menlo*bold at 12pt] but had to change that to \definefont [RPN][file:Menlo.ttc at 12pt] to get it compile. I thought it was something odd about Menlo (which is a Macos system font) at first which is why I changed to using the name: syntax but when this other problem came up I realised it too had worked previously. — Bruce Horrocks Hampshire, UK
