Everything Change can do in your project

Design an API versioning and deprecation policy: semver rules, sunset timelines, and communication channels.

Audit existing changelog and deprecation practices: find missing entries, undocumented breaks, and stale deprecations.

Write a changelog entry or release notes for an API version: breaking changes, new features, fixes.

API docs developers actually finish reading.

Working examples that copy, paste, and just run.

Mock servers and contract tests before the real API exists.
