 description: The Azure SQL Database management API provides a RESTful set of web services that interact with Azure SQL Database services to manage your databases. The API enables you to create, retrieve, update, and delete databases.

 ## Composite packages
 
 The following packages may be composed from multiple api-versions.
 
+### Tag: package-composite-v4
+
+These settings apply only when `--tag=package-composite-v4` is specified on the command line.
+
+This section contains the "composite-v4" set of APIs, which is composed from a selection of api-versions that will remain backwards compatible with "v4" clients such as .NET SDK Microsoft.Azure.Management.Sql version 1.15.0-preview.
+
+APIs must only be added to this section when the API is publicly available in at least 1 production region and at least 1 generated client has been tested end-to-end.
