Hello Luigi,
> > \hsize1in > \input mcnish.tex > \bye > > shows no diffs among 1.07.0 and 1.09.3 experimental lot's of my test files don't have any changes. But some have quite visible changes. I have played with the experimental branch. The offending commit ID is 6844. "w -> c (HH)" Since then all versions show the changed behaviour. I currently can't prepare a test file (plain/LaTeX), since I don't have a LuaTeX 1.0.9 compatible luaotfload here. Will try to prepare one in the next days. Patrick
