DESCRIPTION Branch switching wasn't possible in earlier versions. If user deploys "master" branch first and then wants to switch to "pages" branch, they would have to delete the Pages-managed copy of the repository to re-initialize the repository. This patch introduces changes to switch to user configured branch on startup and at each repository update.
