This follows swiftly on the heels of the [project release](https://opensearch.org/blog/releases/2022/05/opensearch-2-0-is-now-available/) of OpenSearch version 2.0 on May 26. Instaclustr’s OpenSearch managed service is based on the truly open source, Apache 2.0 licensed, OpenSearch project. Since the OpenSearch project reached GA in July 2021, it has been steadily making enhancements. Key features that have been added to OpenSearch and OpenSearch Dashboards in version 2.0 include: - Upgrading to Lucene 9.1, which is the underlying search library used by OpenSearch. - Shifting towards inclusive naming, with *Master* and *blacklist/whitelist* usages being deprecated in 2.0. Instaclustr has initially reflected these changes in our management console. - Geolocation improvements in OpenSearch Dashboards to allow updates to Map Tiles more frequently. - Introducing a circuit breaker in OpenSearch Dashboards to assist with managing resource issues. - Bumping NodeJS from v14.18.2 to v14.19.1 Since the release by the project on May 26, 2022 Instaclustr has been conducting the necessary testing to release OpenSearch 2.0 in public preview. During this public preview running clusters are not covered by our standard SLAs, nor are recommended for production workloads. Instaclustr will be conducting performance baselining and additional testing to ensure that we can offer industry leading support and mark OpenSearch 2.0 for general availability. ![]() **Paul Aubrey - VP Product Management at Instaclustr.**We’ve worked hard to make version 2.0 of OpenSearch available in preview shortly after its release. The preview release gives our customers the confidence that Instaclustr will stay up to date with OpenSearch releases. Additionally it allows our customers to be able to start evaluating and testing the new features, allowing them to plan out their development roadmaps with more certainty. Instaclustr will continue to maintain and patch version 1.x of OpenSearch, as this is recommended as a stepping stone for customers to migrate to OpenSearch. Version 1.3.2 of OpenSearch has also recently been released on the Instaclustr SaaS Platform. Existing customers running OpenSearch or Open Distro for Elasticsearch can contact our Support team if they wish to upgrade their existing clusters to the last version of OpenSearch.
