BackwardCompatibility
From APIDesign
BackwardCompatibility is the tool that helps us, software engineers, practice the style of DistributedDevelopment. In the situation when we build our applications from hundreds and hundreds of external libraries, when we cannot control their schedule, yet we need new upgrades of such downstream libraries. BackwardCompatibility is the mantra that allows us reach smooth Upgradability of such components in our systems.
