When creating and editing content to display in the environment workspace, it's now easier for content editors to manage the editing process. A single user can now check out content, effectively locking it for editing. Once their edits are completed and saved, the content can be checked back in. 

If content is checked out to someone who is no longer editing it, there is also the ability to override the check out. 

If you're collaborating on content, be sure to check with the other user before overriding their check out.
