Under Semantic Versioning, you remove a public function from a library at version 2.4.1. The next version is…

Options

1. 2.4.2
2. 2.5.0
3. 3.0.0 (Correct option)
4. 2.4.1-beta

Answer

3.0.0

Why

SemVer versions are MAJOR.MINOR.PATCH.

• PATCH (2.4.2): bug fixes, nothing breaks.
• MINOR (2.5.0): new features, old code still works.
• MAJOR (3.0.0): breaking changes, old code may stop working.

Removing a public function breaks users who call it, so it is a MAJOR bump.

Remember

Breaking change → MAJOR. New feature → MINOR. Fix → PATCH.
