The changelog generator did not detect properties that were added to a new
version with error-level deprecation (indicating immediate removal). This
commonly occurs when upgrading dependencies like Flyway 10, where properties
are removed without prior deprecation.
Modified the computeDifferences method to detect properties that only exist
in the new metadata with error-level deprecation and properly mark them as
DELETED in the changelog.
