Make and save edits to published posts/pages in WordPress without immediately replacing the public content.
BU Versions is a WordPress plugin that adds new workflows to WordPress that make it possible to create, review, and schedule changes to published content with ease.
With BU Versions, you can clone any published post in WordPress (page, post, or custom post type) to edit and save an alternate version of the post without replacing the public content. You can make multiple edits over any timeframe, all done “behind the scenes” without disruptive or unreviewed changes to the live content. This enables a publishing workflow for edits to content that need to be reviewed and approved before being re-published. Once ready, publishing your version will replace the original post.
