Additional labels for pre-release and build metadata are available as extensionsto the MAJOR.MINOR.PATCH format.## IntroductionIn the world of software management there exists a dreaded place called“dependency hell.” The bigger your system grows and the more packages youintegrate into your software, the more likely you are to find yourself, oneIn systems with many dependencies, releasing new package versions can quicklybecome a nightmare. If the dependency specifications are too tight, you are indanger of version lock (the inability to upgrade a package without having torelease new versions of every dependent package). If dependencies arespecified too loosely, you will inevitably be bitten by version promiscuity(assuming compatibility with more future versions than is reasonable).Dependency hell is where you are when version lock and/or version promiscuityprevent you from easily and safely moving your project forward.As a solution to this problem, we propose a simple set of rules andrequirements that dictate how version numbers are assigned and incremented.These rules are based on but not necessarily limited to pre-existingwidespread common practices in use in both closed and open-source software.For this system to work, you first need to declare a public API. This mayconsist of documentation or be enforced by the code itself. Regardless, it isimportant that this API be clear and precise. Once you identify your publicAPI, you communicate changes to it with specific increments to your versionnumber. Consider a version format of X.Y.Z (Major.Minor.Patch). Bug fixes notaffecting the API increment the patch version, backward compatible APIadditions/changes increment the minor version, and backward incompatible APIchanges increment the major version.We call this system “Semantic Versioning.” Under this scheme, version numbers
