But \updateparagraphproperties (see Hans’ message) helps, it’s just inconvenient. depends ... if you're in some group before a \par is given you won't get looseness which is way harder to track down, and carrying that on eover an egroup is not something you want to do (let alone carrying over 20 groups)

In my magazine and book projects, I sometimes fix pagebreaking by stretching paragraphs with \looseness=1 Unfortunately this works _in my project_ only with MkIV, i.e. \looseness has no effect with LMTX. I tried different examples (e.g. the attached file) and can’t reproduce the problem, there MkIV and LMTX always behave the same. So it must be something in my settings. What could cause the difference? I tried English and German and different settings of alignment and tolerance. Might it be font dependent?

explained in manuals ...

\startlinenumbering \startparagraph Weit .. beirren. \stopparagraph \stoplinenumbering

\startlinenumbering \startparagraph\looseness=+2 Weit .. beirren. \stopparagraph \stoplinenumbering

\startlinenumbering \startparagraph Weit .. beirren. \looseness=+2\updateparagraphproperties\stopparagraph \stoplinenumbering

in lmxt we freeze the properties set when a paragraph starts (contrary to using the last set value which actually fails when you set it inside a group)

so, when you change some property mid paragraph you need to update the properties in order for them to be effective (can be done for looseness only if really needed); that works independent of grouping so it's more robust

Ok, but I thought I needed to use \looseness directly at the beginning of the paragraph, since it’s forgotten after the next \par? HR
