 - Updated the `Microsoft.Azure.Amqp` dependency to 2.6.9, which contains several bug fixes. _(see: [commits](https://github.com/Azure/azure-amqp/commits/hotfix/))_
 
+- Updated the transitive dependency on `System.Text.Json` to 6.0.10 via `Azure.Core` 1.44.1.  Though Service Bus does not perform JSON serialization and was not vulnerable, the .NET 9 SDK was emitting warnings during scans due to a flaw in the previous `System.Text.Json` dependency.
