Does Sitefinity Cloud support automatic Sitefinity upgrades?

Sitefinity Cloud is provided as a service by default and is always running on the latest version without the need for any customer involvement. 

For the ASP.NET Core renderer application which is customizable and under customer control, an automated process runs daily checks for updates and executes a step-by-step upgrade routine. You're duly notified via email and have full control over when to merge and promote the upgrade.

Note: There is no such process for the Next.js renderer technology at this point. 

In cases where the Developer Extension toggle is enabled, the same automated upgrade process applies to the Sitefinity CMS application.
