Perforce is coming up with a new feature called  "streams". Not mentioned when it will be released. But they are  promoting that, this feature will enhances branch management and reduces  merge issues.
What is a stream?
                 A stream describes about branch like depot location, owner, it's parent  branch and more. It is a branching and merging application based on the  perforce system.
Notable features:
·         Streams  provide a centralized control to manage project related workspaces.  Just setup one stream view and link your workspace to that stream.                Whenever stream view changes, it automatically update workspace views.
·         Streams can be used to compute sensible defaults for merges· P4V is being enhanced to show streams in a slick visual flowchart, and to offer a simple interface for sophisticated stream tasks.
