A package version uses a semantic versioning format that provides information about the types of changes made in each release. For details on the version format, go to Semantic Versioning 2.0.0.
Typically, the version is composed of one to three period-separated integers, such as 2.1.4, where each integer provides information about the version in the format [Major].[Minor].[Patch]:
Major: A major revision number.
Minor: A minor revision number.
Patch: A maintenance release number.
