Semantic Versioning (SemVer) is a versioning scheme for software that
uses MAJOR.MINOR.PATCH format. MAJOR for significant, possibly
breaking changes; MINOR for backward-compatible additions; PATCH for
bug fixes. It aids communication, compatibility prediction, and
dependency management. In apps dependent on specific library versions,
SemVer guides parsing and validates compatibility, ensuring apps use
appropriate dependencies.
<valid semver> ::= <version core>
| <version core> "-" <pre-release>
| <version core> "+" <build>
| <version core> "-" <pre-release> "+" <build>
