In the name of continuous delivery, we recently changed our Software Development Cycle (SDLC). Instead of working on just two major branches using SVN (current and future sprint), we create a branch for every new feature and issue using git. Once verified and tested, these feature branches get merged into the master branch. With Jenkins […]
