Launch your app or game : Google Play Academy

A release is a combination of one or more build artifacts that you'll prepare to roll out an app or an app update. Release management on the Google Play Console gives you the tools to test, launch, and track your app's releases. You can iterate your ideas with a small group of trusted users, improve the quality based on actual user data, flexibly rollout releases with control over the timing, pace, and targeted devices, and track performance per release.
