phpDocumentor uses the rules as layed out in the Semantic Versioning Specification version 2.0.0 [SEMVER].
What is considered the “API”?¶
The “API” as intended with the Semantic Versioning specification consists of three parts:
- # Commands, any command exposed by phpDocumentor is considered to be part of the API. As such commands or their options
- may not be removed or changed without increasing the major version number.
