@DavidCarlisle The main things that broke are imho all the redefinitions of internal pgfkeys commands so some public tikz/pgf developer is needed here ...
@daleif every document compiled with lualatex is fine, as it shows the version of luaotfload-main. But the update is really missing, it should now say 2019-05-18 2.97.
I don't know why, but I wrote a parser that translates \romaji{niku} into にく the last night. Does anybody know whether such thing already exists in LaTeX? (I know there is kanaparser for LuaTeX, but only found out by chance when I entered texdoc kana)
Oh, and \romaji{TABERU} translates to タベル (guess what that means in English)
