API Client SDK Versioning Basics

Version SDKs without breaking clients

Versioning client SDKs means aligning releases to API changes, keeping semantic versions, providing clear changelogs and migration guides, and supporting overlapping versions during deprecation windows.

Align to API

Mirror API versions; use semantic versioning for changes.

Document

Provide changelogs, migration notes, and examples per release.

Deprecate

Support overlapping versions briefly; warn and retire cleanly.
