Branch by abstraction is a kind of set piece technique that is used effect a longer to complete change in the trunk.

Branch by abstraction model. Branch by abstraction is a technique for making a large scale change to a software system in gradual way that allows you to release the system regularly while the change is still in progress. There could easily be pressure to create a branch for this somewhere that can be unstable for a period of time before it completes and gets merged back somewhere. We begin with a situation where various parts of the software system are dependent on a module library or framework that we wish to replace.
