New naming convention is that the <a href="/fine-reader/engine/guided-tour/advanced-techniques/programming-aspects/working-with-collections#temporary_collections">temporary collections</a> have <strong>Collection</strong> postfix in their name, while this is a <a href="/fine-reader/engine/guided-tour/advanced-techniques/programming-aspects/working-with-collections#read-only_collections">read-only collection</a>.</p></td></tr><tr><td><p><strong>FindLicense</strong></p></td><td><p>Renamed</p></td><td><p>This method has been renamed to <strong><a href="/fine-reader/engine/api-reference/license-related-objects/licenses/find-method">Find</a></strong>.
