The version history of the article records every modification. You can revert the article to any specific version whenever you wish. An article's initial version is formed upon its creation. Once the article is published, its version becomes fixed. A new version is generated with each additional edit made to a published article. If modifications to the draft are rolled back, the draft version is also eliminated.
