In the [Delete sensitive information from commits](https://docs.gitlab.com/ee/topics/git/numerous_undo_possibilities_in_git/#delete-sensitive-information-from-commits) section of the **Undo options in Git** documentation a usage of git filter-branch is given.
However, when reading the [Reduce repository size](https://docs.gitlab.com/ee/user/project/repository/reducing_the_repo_size_using_git.html) documentation, it is recommended to use git filter-repo instead.
Isn't that confusing ?
