How to squash specific commits that have been pushed to remote?

Question

I have made the following commits in my branch and pushed them to remote

commit 5
commit 4
commit 3
commit 2
commit 1

I now want to squash commits 1, 2 & 3 and remove commits 4 & 5 (dont need the changes anymore) How can i do this?

Once pushed, you cannot easily change the history without affected other users, so it becomes a communication problem.

One approach would be:

• to squash and drop your commit in a separate branch
• push that branch for others to examine
• when everyone agrees on the new history, rename the branch (locally and remotely)
  • "git: renaming branches remotely?"
  • "Git: Rename “master” branch for both local and remote repository"
• ask everybody to reset --hard their branch to the new origin/branch
