Content Moderation is a core module that adds workflow states to content. Instead of content being simply published or unpublished, you can define states like Draft, In Review, Published, and Archived.
Pair it with the Workflows core module to define the transitions between states and who can perform them. For example, an author can move content from Draft to In Review, but only an editor can publish it.
Content Moderation integrates with revisions, letting editors work on a draft version while the published version remains live. This is invaluable for teams with editorial workflows or compliance requirements. It works with core content types without requiring custom code, and the admin interface makes configuration straightforward. For any site with multiple editors and a review process, Content Moderation should be one of the first modules you enable.
