# Revisions & changelog

### About revisions <a href="#about-revisions" id="about-revisions"></a>

Every time a change is made on products, variants, categories or global list values, new revision is registered for the entity with the associated changes. Thus, a full history log is recorded for each of these entity types.

The tracking of revision changes can be disabled altogether, on specific product structures or on specific attributes.

### Changelog <a href="#changelog" id="changelog"></a>

From the registered revisions on each entity, a complete changelog is available through the UI of Struct PIM, in which all changes can be visually seen. From the changelog, revisions can be rolled back, if the changed made in a specific revision supports rollback.
