Which semantic versioning increment is used for backwards-compatible bug fixes?

• A. Major
• B. Minor
• C. Patch
• D. None

Answer: (C)

In semantic versioning, the patch increment is specifically designated for backwards-compatible bug fixes. This means that when a developer addresses bugs—issues that do not introduce new features or break existing functionality—they would increment the patch version. For example, if the current version is 1.0.0 and a bug fix is released, the new version would be 1.0.1. This approach clearly communicates to users of the API that they can update to the new version without any risk of breaking existing functionality. It emphasizes stability and reliability within a software environment, allowing users to have confidence in their upgrades. Major and minor increments serve different purposes: a major version change implies breaking changes that could disrupt existing implementations, while a minor version change introduces new features that remain backwards-compatible. "None" suggests that there is no relevant increment, which does not align with the principles of semantic versioning. Thus, the patch increment is the appropriate choice for indicating the resolution of bugs in a backwards-compatible manner.
