We recently (February, 2026) developed a hyphenation dictionary for the Kazakh language.
After completing this project, the natural question arose of developing official support for the Kazakh language in TeX.
Kazakh language support has been implemented to work with XeLaTeX, LuaLaTeX, and pdfLaTeX macro packages, they all work with babel package. TeXLive 2025 on Linux was used for testing.
Hyphenation patterns support files were sent to maintainers.

XeLaTeX and LuaLaTeX support is also compatible with polyglossia.

These files should be located in the following locations
texmf-dist/tex/generic/babel/locale/kk/babel-kk.ini
texmf-dist/tex/generic/babel-kazakh/kazakh.ldf     
texmf-dist/tex/generic/babel/kazakh.sty            
texmf-dist/tex/latex/polyglossia/gloss-kazakh.ldf  
texmf-dist/tex/latex/polyglossia/gloss-latex.ldf   
texmf-dist/tex/latex/biblatex/lbx/kazakh.lbx       

We provide also sample files, to show the work of our package.
BibTeX database file is also included to demonstarte compatibility with BibLaTeX.
Notice that biblatex support is not complete yet in this initial version, 1.0, it will be completed soon.
