The Graph API Changelog lists the changes in the Graph API schema by date. The [Graph API Changelog](https://developer.workday.com/graphapi-changelog) is in the <b>Reference</b> section of the Developer Site menu.

You can filter the changelog entries by:

<table><thead><tr><th>Filter</th><th>Description</th></tr></thead><tbody><tr><td><b>Breaking</b></td><td>Changes that require you to update existing queries or mutations to avoid breaking an app. <p>Workday carefully reviews each schema update that's categorized as a breaking change. We ensure that a field isn't used before removing it from the schema.</p></td></tr><tr><td><b>Non-Breaking</b></td><td>Changes that you can uptake in your app. <p>All schema updates are non-breaking changes, except for changes marked for deprecation.</p></td></tr><tr><td><b>Field</b></td><td><ul><li>New or updated queries and mutations. Queries are fields of the object type <code>Query</code>, and mutations are fields of the object type <code>Mutation</code>.
</li><li>New or updated type fields.
</li></ul></td></tr><tr><td><b>Type</b></td><td>New or updated business objects, data sources, and other schema types.</td></tr><tr><td><b>Input</b></td><td>New or updated input types for mutations.</td></tr></tbody></table><br/>
