Intermediate Topic 19 of 50 DevOps & Tooling

Semantic Versioning

Version numbers conveying compatibility meaning.

How it works

Semantic Versioning writes versions as MAJOR.MINOR.PATCH. Increment MAJOR for incompatible API changes, MINOR for backward-compatible new features and PATCH for backward-compatible bug fixes. Pre-release tags such as 2.0.0-beta.1 and build metadata add detail, and version 0.y.z signals an unstable API. Version ranges in package managers rely on this contract: ^1.2.3 accepts any 1.x release at or above 1.2.3, while a tilde range such as 1.2.3 with a leading tilde accepts only patch updates. A changelog documents what each release contains, and tags in Git mark release commits.

Where it is used

Libraries, frameworks and APIs use it so consumers can upgrade safely, and automated tools use it to decide which updates to apply without review.

Common pitfall

A breaking change released as a minor or patch version breaks everyone who trusted the range. Be honest about what counts as the public API, deprecate before removing and use tests of the public interface to catch accidental breaks.
