[Koha] question about git install

Hi! I've made a git install of koha. I've followed these instructions git clonehttp://git.koha-community.org/koha.git kohaclone cd kohaclone git checkout 3.10.04 So, when i make a git status, i've this # On branch v3.10.04 # Untracked files: # (use "git add <file>..." to include in what will be committed) # # MYMETA.json # MYMETA.yml # Makefile # blib/ # koha-tmpl/intranet-tmpl/prog/fr-FR/ # koha-tmpl/opac-tmpl/prog/fr-FR/ # pm_to_blib nothing added to commit but untracked files present (use "git add" to track) But, after installation, i'm on 3.11 (so, the next version). How can i solve this problem? Best regards samuel
