Explanation When you edit an article in Salesforce Knowledge, you can choose to flag it as a new version when you publish it. This option creates a new version of the article with a new version number and keeps the previous version in an archived state. The archived version is still associated with the closed cases that it was attached to, while the new version is available for future cases. This way, you can see that a prior article version was associated with the closed cases. Verified References: [Flag an Article as a New Version When You Publish It]
