# Changelog

> Where AppSignal records what shipped: the product changelog on appsignal.com, and the release notes each integration keeps with its releases.

The product changelog records what we ship across AppSignal: new features, changes to features you already use, and the fixes that come with them.

  Integration releases
</h2>

Integrations version and release on their own schedule, separately from the product, and each one records its changes with its releases on GitHub. These are the notes to read before an upgrade, because they name the configuration options, instrumentation, and minimum language versions that changed.

Some features are available before they reach the changelog. [AppSignal Labs](/labs) is where those land first, and it explains what to expect from a feature that is still changing.
