Open the Branches entry in your space (provided by the Page Branching Forge space page) to see every active branch in the space in one table. From there you can jump to any branch.
Approval status
In spaces where merges require approval, the table gains a Status column that shows where each branch stands: Edited, Waiting for approval, Approved, Changes requested, or Approval outdated. The column is hidden in spaces that do not require approval.
If you are an approver who may decide on a branch, its row also offers Review diff to decide. That opens the diff for the branch so you can approve it or request changes without leaving the overview. See Merge Approval for the full workflow.
Approval activity
Space administrators additionally see an Approval activity log below the branch table: who submitted, approved, rejected, or merged which branch, when, against which page versions, and any comment that was given. Entries stay in the log after a branch page has been merged, archived, or deleted, and older entries load in batches with Show older activity.
