What is the primary difference between using semantic versioning (SemVer) and a date-based versioning scheme for a software library?

The primary difference lies in the information conveyed: Semantic Versioning (SemVer) communicates the *natureof changes made to the software, signaling the impact on users and dependent systems, whereas date-based versioning only indicates *whena change occurred, offering no inherent information about its impact. SemVer uses a three-part version number (MAJOR.MINOR.PATCH) to explicitly denote compatibility and functionality changes. The MAJOR version signifies incompatible API changes, meaning existing code using the library might break after upgrading. The MINOR version indicates new features added in a backwards-compatible manner, where existing code will continue to work but can now leverage new capabilities. The PATCH version denotes backwards-compatible bug fixes, implying no functional changes but improved stability. Date-based versioning, such as '2024.01.26', simply indicates the year, month, and day of the release. While useful for chronological tracking, it provides no intrinsic information on whether the update introduces breaking changes, new features, or merely fixes bugs, forcing users to investigate release notes or changelogs to understand the impact of upgrading. Therefore, SemVer promotes better communication and management of software dependencies by clearly signaling the type and scope of changes, unlike date-based versioning, which only provides temporal context.
