-## New feature
-
-* MSI Based authentication for SQL Databases.
-  
-    HDInsight now offers Managed Identity for secure authentication with SQL databases in its clusters offerings. This enhancement provides a more secure mechanism for authentication. For more information see, [Use Managed Identity for SQL Database authentication in Azure HDInsight](./use-managed-identity-for-sql-database-authentication-in-azure-hdinsight.md).
-    
-   To use Managed Identity with SQL databases, follow these steps: 
-
-    * This feature isn't enabled by default. To enable it, submit a [support ticket](https://portal.azure.com/#blade/Microsoft_Azure_Support/HelpAndSupportBlade/overview) with your subscription and region details.
+## Issues fixed
 
-    * After the capability has been enabled, proceed to recreate the cluster.
+* Managed identity based authentication for WASB when storage has network ACL enabled.
+* Managed identity based authentication for SQL databases when availability zones are used.
+* Security fixes.
 
-    > [!NOTE]
-    > Managed Identity is currently available only in public regions. It will be rolled out to other regions (Federal and China regions) in future releases. 
+## Updates
 
-## New Regions 
-
-* New Zealand North.
+* Active PIN requests for creating HDInsight clusters with predetermined image versions will be revoked/cancelled on 26 May 2025. Beyond this date, customers will only be able to create clusters using the updated (compliant) images of each HDInsight version. This measure is intended to improve cluster security and prevent potential issues with clusters and gateway nodes. 
 
 ## Reminder
 
 * HDInsight service transitioned to use standard load balancers for all its cluster configurations due to [deprecation announcement](https://azure.microsoft.com/updates/azure-basic-load-balancer-will-be-retired-on-30-september-2025-upgrade-to-standard-load-balancer#main) of Azure basic load balancer.
 
-  > [!NOTE]
-  > This change is available in all regions. Recreate your cluster to consume this change. For any assistance, contact [support](https://ms.portal.azure.com/#view/Microsoft_Azure_Support/HelpAndSupportBlade/~/overview).
-
   > [!IMPORTANT]
-  > When using your own Virtual Network (custom VNet) during cluster creation, be advised that the cluster creation won't succeed once this change is enabled. We recommend referring to the [migration guide to recreate the cluster](./load-balancer-migration-guidelines.md).
+  > By default, all newly created HDInsight clusters are configured with a Standard Load Balancer. We recommend referring to the [migration guide to recreate the cluster](./load-balancer-migration-guidelines.md).

 * [Basic and Standard A-series VMs Retirement](https://azure.microsoft.com/updates/basic-and-standard-aseries-vms-on-hdinsight-will-retire-on-31-august-2024/).
    * On August 31, 2024, we'll retire Basic and Standard A-series VMs. Before that date, you need to migrate your workloads to Av2-series VMs, which provide more memory per vCPU and faster storage on solid-state drives (SSDs).
    * To avoid service disruptions, [migrate your workloads](https://aka.ms/Av1retirement) from Basic and Standard A-series VMs to Av2-series VMs before August 31, 2024.
