 ### New features
 
+- [azcmagent show](azcmagent-show.md) now reports extended security license status on Windows Server 2012 server machines.
 - Introduced a new [proxy bypass](manage-agent.md#proxy-bypass-for-private-endpoints) option, `ArcData`, that covers the Azure Arc-enabled SQL Server endpoints. This will enable you to use a private endpoint with Azure Arc-enabled servers with the public endpoints for Azure Arc-enabled SQL Server.
 - The [CPU limit for extension operations](agent-overview.md#agent-resource-governance) on Linux is now 30%. This increase will help improve reliability of extension install, upgrade and uninstall operations.
 - Older extension manager and machine configuration agent logs are automatically zipped to reduce disk space requirements.
