# DBSyn Phase 62 — Schema Change Review

Right-click a database in the Schemas navigator and choose **Review Schema Changes…**.

Select **Refresh Introspection** to retrieve the latest table, view, and column metadata. DBSyn compares the new snapshot with the previous cached snapshot, reporting added and removed tables/views/columns, and changed column attributes. Existing persistent introspection snapshots provide the baseline across launches. The change report is session-only; the current snapshot is saved for the next comparison.

The first introspection without a previous snapshot establishes the baseline and does not report differences. Failed introspections preserve the previous snapshot and do not create a comparison report. No database schema is modified by this feature.

Validation: source changes reviewed and ZIP integrity checked; macOS compilation and live MySQL testing remain necessary.
