"Branching" is a common capability provided by the various version control systems that exist today. At a minimum, branching allows concurrent changes to be made to a source file. This can be used to support something like making changes to the code for a bug fix and for the next major release at the same time. "Merging" is the other side of the equation. The branch is 'hiding' the fix changes from the next major release. At some point in time you're going to need to combine the changes together, or when the release goes into production it will re-introduce the bug.
