Unclear How this changes which commits a review compares against is not known.

What

When Claude Code works out the base branch for a review, the point your changes are compared against, it now always marks the result as coming from the last fetch, Git's FETCH_HEAD. Before, it marked it as the remote's default branch whenever the base was not FETCH_HEAD.

Why

This could change how Claude Code finds the starting point for a diff.
