> * lltjext.sty: adapt to LaTeX 2025-11-01 (gh/#36)
> * luatexja-adjust.sty: fix incorrect spacing between

> * 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.
