The following example gave with the generic fontloader from 2018-12-19 and luatex 1.07 two identical lines. With a fontloader from 2019-01-07 and luatex 1.09 the first line is wrong at the left side, the "j" is squashed into the next glyph:
\font\test = {name:FreeSerif:mode=node;script=arab;language=DFLT;+tlig;+ccmp;+locl;+isol; +fina; +fin2;+fin3;+medi;+med2;+init;+rlig;+calt;+liga;+cswh;+mset;+curs;+kern;+mark;+mkmk;} \test \textdir TRT \pardir TRT \bodydir TRT \pagedir TRT
