Your baselines are preserved between branches, even when squashing or rebasing wipes the Git history. If you use the “squash” or “rebase” merge feature on Pull Requests, then a commit is created on your base branch that is not a descendant of the commits for the PR. See the diagram below. one for the blackbird one for the crow ending
