When Reviews are updated and re-published, any corresponding translations are archived on the Cochrane Library and marked as out-of-date on Cochrane.org. Therefore, it is recommended to update existing translations to the most recent review version.
The "Diff versions" button is available when a previous version has been translated. You can click on the button to see which changes have been made in the English text to better understand how much work will be involved to update the translation.
This written guide explains how you can search for out-of-date translations in Archie to identify translations that need to be updated.
