Semantic versioning (SemVer) is a versioning system designed to convey meaningful information about software updates through a standardized format. It follows the structure MAJOR.MINOR.PATCH, where each segment represents a specific type of change. The MAJOR version is incremented for incompatible changes that may break backward compatibility, the MINOR version is updated for backward-compatible feature additions, and the PATCH version increases for backward-compatible bug fixes. This clear structure helps developers and users understand the impact of updates, manage dependencies, and ensure compatibility across different versions of a project. Semantic versioning promotes transparency and predictability in software development and distribution.
