Elasticsearch version 7.17.6

Elasticsearch version 7.17.6

Also see Breaking changes in 7.17.

Known issues

  • 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)
