(important) problem of luatexja-fontspec

[Atsuhito Kohda <atsuhito_k@tokushima-u.ac.jp>]

Hi Norbert and all,

I recently noticed a problem of LuaTeX-ja in Debian/testing.
The problem is
* LaTeX2e 2017.01.01 is released and is in Debian/testing
* LuaLaTex uses TU encoding by default, and fontspec is updated
* luatexja-fontspec of LuaTeX-ja was not compatible with
  the new fontspec
* the author of LuaTeX-ja updated luatexja-fontspec at 2017.01.24
  to fix the problem

I guess he uploaded it to CTAN and so TeXLive but I don't
know when it comes into Debian package, and further,
Debian is in freeze state already.  So I write this e-mail.

The error is critical (for LuaLaTeX-ja users) and lualatex
fails to compile even very simple TeX file as follows:

(/usr/share/texlive/texmf-dist/tex/luatex/luatexja/addons/luatexja-fontspec-24.
sty
! Undefined control sequence.
l.352 \__fontspec_define_feature_option:nnnnn
                                           {CJKShape}{JIS2004}{20}{100}{+jp04}
?


I installed manually the new LuaTeX-ja in /usr/local and
the problem is certainly fixed.
So I believe Debian must update LuaTeX-ja (texlive-lang-japanese)
for stretch.
If you need any further information please let me know.

Thanks for your maintenance.
