Elastic Cloud Hosted breaking changes
Elastic Cloud Hosted breaking changes can impact your Elastic applications, potentially disrupting normal operations. Carefully review them and take the necessary steps to mitigate any issues.
In addition, before upgrading your hosted deployments, review the breaking changes for any Elastic Stack applications that you're using.
Removed deprecated _upgrade endpoint
The deployments/<deployment_id>/<resource-kind>/<ref_id>/_upgrade endpoint was already deprecated and has now been removed. To upgrade a deployment using the API, you should instead use the /deployments/{deployment_id} endpoint.
Removed Elasticsearch and Kibana URLs from supported settings
ApmSystemSettings, IntegrationsServerSystemSettings, KibanaSystemSettings and EnterpriseSearchSystemSettings no longer support elasticsearchUrl and kibanaUrl fields.
