API changes between releases or versions

In

the following is mentioned:

“This document is not meant as a complete guide for developing plugins but more as a changelog for changes in Grafana that can impact plugin development. Whenever you as a plugin author encounter an issue with your plugin after upgrading Grafana please check here before creating an issue.”

If I update Grafana to a new release the statement above indicates that there can be changes to the API. How much can I rely on the API for the sources and the panels?
