@Ton Boelens Welcome to Microsoft Q&A Forums and thank you for your interest in Azure services.
Updates to Azure services are carried out in a very seamless manner so that your apps don't experience any downtime.
Upgrades are automatically rolled back if any issues are detected by our telemetry and monitoring processes.
Breaking changes if any are communicated well in advance via blogs, email and notifications in the Azure portal.
You can create a filter on the products you are interested in and follow the announcements on this page or subscribe to the RSS feed to get tailored information.
Please let me know if you have any further questions.
