OpenSearch® 2.11 Is Now Available on the Instaclustr Managed Platform 

OpenSearch® version 2.11 has now been released to the Instaclustr Managed Platform! This release brings a number of enhancements and improvements to OpenSearch.

OpenSearch 2.11 resolves two vulnerabilities, CVE-2023-45807 and GHSA-8wx3-324g-w4qq. CVE-2023-45807 relates to a vulnerability found in multi-tenanted OpenSearch Dashboard deployments. GHSA-8wx3-324g-w4qq relates to an issue with how OpenSearch handled requests on the HTTP layer. You can find out more about these vulnerabilities, how we assessed them, and mitigation approaches on our security advisory blog post. 

One of the key highlights of this new release is the update to OpenSearch Dashboards. An entirely new user interface has been implemented, providing the same functionality but with improved usability and an updated look and feel. You can find out more about what has been changed here 

Looking under the hood, this new release brings some solid enhancements.  

The OpenSearch Index Management Plugin now provides a unique ID to each rollup job to help with debugging, and users of the k-NN tool can flush k-NN indices out of the cache via the API.   

The OpenSearch Security Plugin has also been improved with added authorization in the REST layer, making queries more secure. And lastly, customers can now send OpenSearch notifications to Microsoft Teams.  

This latest version of OpenSearch also comes with new and experimental features that we are actively testing for future use on the Instaclustr Managed Platform.  

These features include the Neural Search Plugin (which turns text into vectors that can be stored and searched), and remote backed indices (which automatically creates backups of all index transactions and sends them to remote storage, providing a cost-effective solution for reducing the risk of data loss). We will have more news for you on these features in future updates.  

Customers of the Instaclustr Managed Platform can now begin deploying OpenSearch 2.11 on new clusters through the Console, API, or Terraform. For existing clusters, customers can contact our Support team to upgrade at [email protected]. For new customers, you can spin up an OpenSearch cluster for free through our customer console now.  

 If you have any questions about this update or OpenSearch in general, please contact our friendly team at any time.
