The LuaTeX-ja project submitted an update to the
luatexja
package.
Version number: 20160131.0 License type: bsd
Summary description: Typeset Japanese with Lua(La)TeX
Announcement text: ---------------------------------------------------------------------- * luatexja-preset.sty: support Scale=<fp> and match options when nfssonly option is specified. * Japanese font family inside verb and verbatim environment can be customized by jttdefault. If luatexja-{preset,fontspec} with match option or ltjsclasses are used, tfamily changes current Japanese font fmaily to this jttdefault. * Fixed several bugs.
Note that IVS support (to enable it, load luatexja-otf.sty and execute directlua{luatexja.otf.enable_ivs()}) breaks vertical writing mode with current LuaTeX. (This IVS support works fine with LuaJITTeX, strangely.) ----------------------------------------------------------------------
