How to update wordpress version when using git?

Question

git

For one of our clients we run wordpress websites. For each site, a repository has been created in bitbucket with 2 branches: master and dev.
You need to update the version of WP on all sites. How to do it correctly so as not to "break" the repositories?

Answer 1

Create a branch, name it "update_wp" and change what you need, then merge and you're done.

Answer 2

Upload the new voprdress files and the commit
itself is no different from any change on the site.
what are you hoping to break?
