Git branch or Tag for 12.9?

I want to patch the version, that is installed with the (fantastic!) debian apt-installer, which brings me 12.9. I can not find a suitable branch in git. Which one should I use?

Thx, Bob

Depends which module you exactly want to patch. You can look at for information about where to find the sources.

thx; I just found the branch in the platform moduleā€¦
