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. latex-test-20220207: this did NOT contain the intended fixes for use with recent versions of asy, and the ABOUT PDF had not been updated.
