       Binary incompatibility may result in crashing or incorrect behavior of applications built with an old version of a library if they run on a new one. Source incompatibility may result in recompilation errors with a new library version. The tool is intended for developers of software libraries and Linux maintainers who are interested in ensuring backward compatibility, i.e. allow old applications to run or to be recompiled with newer library versions.
