I am aware that ConTeXt betas might use experimental luaTeX changes (I use both stable and latest and run both), just wanted to report a change in prevgraf result. Apparently with latest beta it reports the number of lines in last page of paragraph (only tested with pars on 2 pages maximum, haven’t tried longer ones). Simple MWE reproduces the case:





A\\ B\\ C\\ D\\ E\\ F\\ G\\ H\\ I\\ J\\ K\\ L \\M\\ N.








Using ConTeXt online always reports « 14 » after the letters, latest ConTeXt reports different numbers if the par before it has been split in 2 pages.
