Semantic Versioning is a versioning scheme used in software development to help manage changes and updates. It consists of three numbers separated by dots, like this: MAJOR.MINOR.PATCH. The MAJOR number increases when there are incompatible changes, the MINOR number increases when new features are added in a backward-compatible manner, and the PATCH number increases for backward-compatible bug fixes. This system provides clarity for developers and users alike, making it easier to understand the impact of updates. By following Semantic Versioning, teams can communicate changes effectively, ensuring that everyone knows what to expect when they upgrade their software.
