+

+* HDInsight 5.0: Ubuntu 18.04.5 LTS Linux Kernel 5.4
+* HDInsight 4.0: Ubuntu 18.04.5 LTS Linux Kernel 5.4
+
+> [!NOTE]
+> Ubuntu 18.04 is supported under [Extended Security Maintenance(ESM)](https://techcommunity.microsoft.com/t5/linux-and-open-source-blog/canonical-ubuntu-18-04-lts-reaching-end-of-standard-support/ba-p/3822623) by the Azure Linux team for [Azure HDInsight July 2023](/azure/hdinsight/hdinsight-release-notes-archive#release-date-july-25-2023), release onwards.

+
+## Updated
+
+* MSI based authentication support available for Azure blob storage.
+
+  * Azure HDInsight now supports OAuth-based authentication for accessing Azure Blob storage by leveraging Azure Active Directory (AAD) and managed identities (MSI). With this enhancement, HDInsight uses user-assigned managed identities to access Azure blob storage. For more information, see [Managed identities for Azure resources](/entra/identity/managed-identities-azure-resources/overview).
+
+
+* 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).
