Hironori Kitagawa submitted an update to the

            luatexja

package.

Version: 20260107.0 License: bsd

Summary description: Typeset Japanese with Lua(La)TeX

Announcement text:

• lltjext.sty: adapt to LaTeX 2025-11-01 (gh/#36)

• luatexja-adjust.sty: fix incorrect spacing between \ltjghostafterjachar\ltjghostbeforejachar (gh/#39)

• Fix the incorrect behavior of shifting baseline in math mode. (gh/#40)

• New implementation for vertical writing. (experimental, gh/#38)

  • NOT enabled by default. To test with new implementation, one has to set "\directlua{luatexja_cmapidv = true}" before loading of LuaTeX-ja.
  • extraction the text from PDF now works better because of using Identity-V Cmap.
  • this implementation uses an "undocumented" feature of LuaTeX, and clashes with some packages.
