description: >-
  Chronosphere publishes no changelog for the Config, Data or State HTTP APIs themselves. The
  Observability Platform product release notes sit behind the application sign-in (More
  information > Release Notes). Two dated changelogs are public, and because the Terraform
  provider is generated one-to-one from the Config API, its release notes are the closest public
  proxy for API change: new resources, new fields and removals land there in step with the API.

  entries:
  - version: 1.35.0
    date: '2026-08-25'
    breaking: true
    additions:
    - chronosphere_synthetic_test resource — probes an endpoint over HTTP, DNS, TCP or TLS from
      Observability Platform tenants and alerts on the result.
    - chronosphere_cloud_integration resource — ingests metrics from a cloud provider through an
      external connection; provider_config is free-form JSON keyed by provider_type, so new cloud
      providers do not require a provider upgrade.
    removals:
    - chronosphere_logscale_alert and chronosphere_logscale_action removed. Remove them from
      configuration and state before upgrading.
    note: >-
      Matches the API: LogScaleAlert and LogScaleAction are present in the Config V1 spec archived
      in this repo from an earlier harvest and absent from the spec published on 2026-08-29.

  scheme: semver
  current_version: 2.84.0
  current_date: '2026-04-15'
  components:

    release train, separate from Observability Platform.
gaps:
- surface: Config V1 / Data V1 / State V1 HTTP APIs
  finding: >-
    No public, dated changelog. API change has to be inferred from the Terraform provider notes or
    by diffing the published Swagger, which is what this repo now does — the 2026-08-29 harvest of
    Config V1 carries 70 paths and 183 operations against the 57 paths and 149 operations of the
    previously archived copy, and no announcement covers the difference.
- surface: Chronoctl
  finding: Release notes require an authenticated Observability Platform session.
