Changelog Breaking Change Extractor — illustrative example

INPUT
Release notes say field full_name is replaced by display_name in version 2.

RESULT
Breaking change: consumers using full_name must review the version-2 response and migrate to display_name as documented.

REVIEW
A breaking-change extract should identify the old behavior, new behavior and stated migration action. Do not treat every release note as a breaking change.

This is a teaching example, not a live execution record.
