scheme_note: >-
  MAJOR.MINOR.PATCH across the whole stack. Release notes are organised per
  PRODUCT (Elasticsearch, Kibana, Logstash, Beats, Elastic Agent, Cloud Hosted,
  Cloud Serverless, ECE, ECK, each APM agent and EDOT SDK), not as one stack
  changelog — an integrator tracking API drift has to watch several pages.
current_version: 9.5.2
current_version_note: >-
  Newest Elasticsearch release named on the release-notes page. The
  co.elastic.clients:elasticsearch-java artifact for 9.5.2 published to Maven
  Central on 2026-08-25, which is the closest reliable date available; Elastic
  does not print release dates on the release-notes page itself.
next_version_in_flight: '9.6'
next_version_evidence: >-
  openapi/elk-stack-kibana-openapi.yaml already carries operations annotated
  `x-state: Experimental; added in 9.6.0` — the published contract is ahead of
  the released stack.

    The release-notes pages do not print a date against any version. This is a
    real gap for anyone assessing API currency: the changelog says WHAT changed
    but not WHEN, so release dates have to be inferred from package registries
    or GitHub tags.
