Branches facilitate work done on parallel releases of a project.
You select the branch you want to work on in the Home tab. You can also create subbranches from the Home tab, and manage them from the Project tab.
Initially, a project contains only a main line in which you work. From the main, sometimes referred to as the main branch, you can create one or more subbranches. From any new branch you can create other subbranches, as many as you need to manage your releases.
The name of the branch you are currently working on appears in the top banner beside the project name.
When you create a subbranch, it contains an exact replica of every project element contained in the parent branch. You can then work on the subbranch without affecting the content of its parent, and eventually merge different branches together (Merging branches).
To understand how different versions of project elements are handled, see Versioning.
