Starting with Git 2.27 (June 2020), a 'git pull' that has to reconcile divergent branches prints a multi-line hint beginning 'Pulling without specifying how to reconcile divergent branches is discouraged'. It is a warning, not an error, and the historical merge behaviour still happens, but it pollutes CI logs and confuses scripts that treat stderr output as failure.

Silence it by choosing a policy explicitly. 'git config --global pull.rebase false' keeps the old merge behaviour, 'pull.rebase true' rebases local commits on top of the fetched head, and 'git config --global pull.ff only' refuses to do anything but a fast-forward, which is the safest default for automation because it fails loudly instead of creating a surprise merge commit.

In scripts, prefer avoiding pull entirely: 'git fetch' followed by an explicit 'git merge --ff-only' or 'git rebase' makes the intent readable and the failure mode obvious.
