Elasticsearch X-Pack version 6.0.0-beta1

Breaking Changes

Security
  • A new bootstrap check enforces that TLS/SSL is required for inter-node communication when running in production mode. See Encrypting Communications.
  • A new bootstrap check enforces that HTTPS is used by the built-in token service when running in production mode. To disable the token service, set xpack.security.authc.token.enabled to false in your elasticsearch.yml. See Token Service Settings.
