asy: The cylinder and triangles tests introduced in the 20160523
release gave various problems on systems running gcc-6.  I attempted
a workaround in the 20160624 release, but reverted the changes to
triangles in the 20160817 release and instead noted that the title
will be on a separate page if the 2016 binary is used on a gcc-6
system.

bibxelatex: test was broken if no korean font had been installed.
Applies to all releases starting from 20160523.  Fixed in the
20160905 release.

Testing for WenQuanYi Zen Hei to use as a possible font was broken.
Claimed to be fixed in the 20190227 release, but wasn't.  Hopefully,
fixed in the 20190318 release.  In fact it wasn't, I added a patch
to my files at www.linuxfromscratch.org/~ken/ : should be ok in the
20210421 release.

There were various font and layout issues for Cantonese, both
variants of Chinese, and Japanese. Fixed in the 20250109 release.

The 20250523 release had a lot of problems with the added lualatexbib
test, and created a 20250531 tarball because of a typo. That has now
been suppressed.
