[NTG-context] unwanted page at end

Using the latest beta, the workaround from the wiki, \setuppagenumbering[alternative=doublesided] \setupsectionblock[frontpart][page=no] \setupsectionblock[bodypart][page=no] \setupsectionblock[appendix][page=no] \setupsectionblock[backpart][page=no] \starttext \startbodymatter% or backmatter etc. After this page, there is another empty one. \stopbodymatter \stoptext ​ fails to prevent a blank page at the end. Is there a new way to do this now? I used to rely on \installpagebreakhandler{last}{}, but this does not seem to work either: it now permits a final page with a page number. Alan
