LindormSearch releases minor version updates to deliver new features, performance improvements, and bug fixes. This page documents the changes in each version.
View or upgrade the LindormSearch version of a Lindorm instance
View the current LindormSearch version in the Lindorm console. To upgrade to a newer version and understand the upgrade process, see Minor version update.
Warning
Keep the following in mind before you upgrade:
-
A version upgrade performs a rolling restart across all LindormSearch nodes. During the restart, shards are automatically moved to available nodes, which may cause brief query jitters. Schedule upgrades during off-peak hours.
-
If your instance has only one LindormSearch node, the service is unavailable during the upgrade. Add LindormSearch nodes before upgrading to maintain availability.
-
The system automatically checks whether the instance is running the latest version. If the Upgrade Minor Version button is not displayed, no upgrade is available.
-
Version rollout may vary by region. The version shown in the Lindorm console is authoritative.
