+
+### Cumulative Update 1
+
+The following updates apply to [!INCLUDE [sssql25-md](../includes/sssql25-md.md)] Cumulative Update (CU) 1.
+
+- **Red Hat Enterprise Linux 10 support**. [!INCLUDE [sssql25-md](../includes/sssql25-md.md)] is fully supported on Red Hat Enterprise Linux (RHEL) 10. For more information, see [Quickstart: Install SQL Server and create a database on Red Hat](quickstart-install-connect-red-hat.md?view=sql-server-ver17&tabs=rhel8%2C2025rhel10&preserve-view=true).
+
+- **Ubuntu 24.04 support**. [!INCLUDE [sssql25-md](../includes/sssql25-md.md)] is fully supported on Ubuntu 24.04. For more information, see [Quickstart: Install SQL Server and create a database on Ubuntu](quickstart-install-connect-ubuntu.md?view=sql-server-ver17&tabs=ubuntu2004%2C2505ubuntu2404%2Codbc-ubuntu-2404&preserve-view=true).
+
+- **Contained availability groups (AGs)**. Enable database create and restore operations directly through the contained AG listener. This improvement eliminates the need to connect to the physical replica, simplifying high availability automation on Linux.
+
+  For more information, see [Enable database creation or restoration in contained availability group sessions](../database-engine/availability-groups/windows/contained-availability-groups-overview.md#enable-database-creation-or-restoration-in-contained-availability-group-sessions).
+
+- **New dynamic management views**. Four new Linux‑specific dynamic management views (DMVs) provide insights into host and virtual memory resource utilization, aiding performance troubleshooting and diagnostics.
