Software versioning is a system used to manage changes and updates in software applications. It helps developers and users track different iterations of a program, indicating improvements, bug fixes, or new features. Each version is typically assigned a unique number, often following a format like Semantic Versioning, which includes major, minor, and patch numbers. Versioning is crucial for maintaining compatibility and ensuring that users have access to the latest features and security updates. It also aids in collaboration among developers, as they can easily identify which version of the software they are working on or referencing. This organized approach enhances overall software quality and user experience.
