 # Release notes - Azure Arc-enabled data services
 
 This article highlights capabilities, features, and enhancements recently released or improved for Azure Arc-enabled data services.
 
+## March 2022
+
+This release is published March 8, 2022.
+
+### Image tag
+
+`v1.4.1_2022-03-08`
+
+For complete release version information, see [Version log](version-log.md).
+
+### Data Controller
+- Fixed the issue "ConfigMap sql-config-[SQL MI] does not exist" from the February 2022 release. This issue occurs when deploying a SQL Managed Instance with service type of `loadBalancer` with certain load balancers. 
+
+
+
+### SQL Managed Instance
+
+- Support for readable secondary replicas:
+    - To set readable secondary replicas use `--readable-secondaries` when you create or update an Arc-enabled SQL Managed Instance deployment. 
+    - Set `--readable secondaries` to any value between 0 and the number of replicas minus 1.
+    - `--readable-secondaries` only applies to Business Critical tier. 
+- Automatic backups are taken on the primary instance in a Business Critical service tier when there are multiple replicas. When a failover happens, backups move to the new primary. 
+- RWX capable storage class is required for backups, for both General Purpose and Business Critical service tiers.
+- Billing support when using multiple read replicas.
+
+For additional information about service tiers, see [High Availability with Azure Arc-enabled SQL Managed Instance (preview)](managed-instance-high-availability.md).
+
+### User experience improvements
+
+The following improvements are available in [Azure Data Studio](/sql/azure-data-studio/download-azure-data-studio).
+
+- Azure Arc and Azure CLI extensions now generally available. 
+- Changed edit commands for SQL Managed Instance for Azure Arc dashboard to use `update`, reflecting Azure CLI changes. This works in indirect or direct mode. 
+- Data controller deployment wizard step for connectivity mode is now earlier in the process.
+- Removed an extra backups field in SQL MI deployment wizard.
