Elasticsearch version 7.17.0

Also see Breaking changes in 7.17.

Known issues

edit
  • Elasticsearch fails to parse system index migration data from the cluster state (issue: #84115)
  • Feature migration refuses to run if all features requiring upgrade have encountered errors (issue: #83917)
  • Migrating system indices fails for tasks with mapper_parsing_exception (issue: #83779)

These issues will impact any subsequent upgrade to 8.x, and are fixed in 7.17.1. We strongly recommend that all users upgrade to a later patch release of 7.17 before upgrading to 8.x.

  • Parsing a request when the last element in an array is filtered out (for instance using _source_includes) fails. This is due to a bug in Jackson parser. Fixed in Elasticsearch 8.6.1 (#91456)
  • 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)
