Also see Breaking changes in 7.17.

Known issues

edit
  • Due to a bug in the bundled JDK 22 nodes might crash abruptly under high memory pressure. We recommend downgrading to JDK 21.0.2 asap to mitigate the issue.
  • The deprecated index.mapper.dynamic setting can break your cluster. It can only be set using the Update index settings API. Symptoms include nodes failing to start or shards failing to allocate. Do not use this setting in versions prior to 7.17.22. The bug is fixed in 7.17.22. (issue: #109160)
