Software versioning is a system used to manage changes and updates to software applications. It helps developers and users track different iterations of a program, ensuring that everyone is aware of the features, fixes, and improvements made over time. Each version is typically assigned a unique number, often following a format like major.minor.patch. This numbering system allows for clear communication about the software's state. For example, a change in the major number indicates significant updates or changes, while a change in the minor number usually signifies smaller enhancements. The patch number often reflects minor bug fixes, helping users understand the software's evolution.
