description: >-
  Checkly publishes a dated product changelog grouped by month, with per-item permalinks and an
  "Also shipped" roll-up under each month. It is a product changelog rather than an API changelog -
  breaking API changes are not called out separately, and the OpenAPI carries no version history, so
  the deprecation flags in the contract are the more reliable read on API change. See
  lifecycle/checkly-lifecycle.yml.
scheme: monthly roll-up with dated in-month entries and per-entry permalinks
granularity: month
current_version: v1 (path-versioned API; the changelog does not version itself)
api_changelog: false
api_changelog_note: >-
  No separate API changelog or release-notes feed for the Public API was found. Consumers track API
  change through the OpenAPI document and its deprecated flags.

notes:
- >-
  The June 2026 entry is the primary provenance for the MCP server captured in mcp/checkly-mcp.yml -
  it is a shipped product, not a preview.
- >-
  Entry dates are month-level in the roll-up headings; individual items carry permalinks but the page
  does not expose per-item ISO dates in its markup, so no day-level dates are asserted here.
