I'm wondering if there has been a regression in the rendering of 
CJK recently? I'm attaching two screenshots from the same code:
one with lmtx-20210509 (correct); and the other lmtx-20210613
(incomplete).

This is what I have in the setups:

% Support for Japanese

\setscript[hanzi]

\starttypescript[serif][sourcehanserifregular]

\definefontsynonym[Serif][name:sourcehanserifregular][features={aalt,h
ist,kern,liga}]

\stoptypescript

\definetypeface[sourcehanserifregular][rm][serif][sourcehanserifregula
r]

\define[1]\JA{\language[ja]{{\setscript[hanzi]\sourcehanserifregular
#1}}}


And this is the code behind the screenshots:

{\tfx

\everypar{\hangafter=1\hangindent=3em\relax}
