The current policy states that during code review, all changes/fixes to the PR should be put in separate commits (unless there is a substantial change on the main branch that will break the PR and you have to rebase + forced push) so the reviewer can see a clear history of changes. But once the code reviewer is done, you have to squash all the commits before merge. Actually, I think we make "Squash and merge" button the only clickable one on the web UI.
