@doncherry Thanks, fixed. (It's called l3kernel now instead of expl3.)

comment using Hoefler Text font under lualatex and MacOSX
This was already discussed and fixed in github.com/khaledhosny/luaotfload/issues/37, but nobody has released the modified blacklist since then.

comment Normal \relax vs. frozen \relax
Generally speaking, \ifx only looks one level deep: it checks whether all tokens have the same indices into the equivalence table, but does not check whether they have the same meaning. The same works with \let\foo=\relax: Now \foo is a token with the meaning of \relax but a different name.

comment Normal \relax vs. frozen \relax
On the other hand, \expandafter\ifx\x\relax is true. This works for all primitives that have a frozen version and therefore appear twice in the equivalence table. With LuaTeX, you can create additional copies of primitives using tex.enableprimitives, and they show the same behavior.
