  (Zendesk Help Center API), the GitHub releases API for github.com/blueshift-labs,
  and the per-page `updatedAt` timestamps ReadMe emits on every
  developer.blueshift.com reference page.
description: >-
  Blueshift publishes NO changelog for its REST API. This artifact records that
  absence honestly, and then records the dated change signals that do exist —
  product release notes for one product surface, SDK releases on GitHub, and the
  per-page revision dates carried in the API reference itself. The reference-page
  dates are the closest thing to an API changelog Blueshift offers: 79 of the 88
  reference pages were revised in April 2026 in what was clearly a single
  documentation overhaul, and six more in July 2026.

  note: >-
    The developer portal runs on ReadMe, which ships a changelog feature; it is
    not enabled. There is no version number for the API as a whole — the
    OpenAPI `info.version` is a static "1.0.0" on every operation document.

current_version:
  api: v1 (with two v2 operations)
  spec_info_version: '1.0.0'
  note: >-
    info.version is 1.0.0 on all 81 published operation documents and does not
    move, so it carries no change information.

    The `updatedAt` frontmatter ReadMe emits on each
    developer.blueshift.com/reference/*.md page, read across all 88 pages.

  interpretation: >-
    The April 2026 cluster is a wholesale rewrite of the API reference, not 79
    independent API changes. The July 2026 pages are the genuinely recent edits.
    This is a documentation signal, not an API-change signal, and should not be
    read as 79 breaking changes.

breaking_changes:
  published: false
  note: >-
    Blueshift publishes no breaking-change register for the API. Combined with
    the absence of a deprecation policy (see lifecycle/), a consumer has no
    forward notice mechanism of any kind for the REST API.

gaps:
  - >-
    No API changelog, no API version history, and a static info.version — three
    independent reasons a consumer cannot answer "what changed since I
    integrated?".
  - >-
    The one release-notes surface that exists covers a different product
    (Launchpad) and is easy to mistake for an API changelog.
