description: >-
  Electricity North West publishes no changelog of its own. The API's changelog is
  the Opendatasoft (Huwise) Explore API version changelog, and it is version-scoped
  rather than dated: it enumerates what changed between v2.0 and v2.1 with no
  release dates and no ongoing entries. That is the honest shape of it — a single
  migration note, not a rolling log. The `Link` response header on a superseded
  version points at this document.
scheme: version-scoped (uri-path versions), undated
current_version: v2.1
dated: false
cadence_claimed: >-
  "New features are added every month and bugs are fixed every week" — within the
  backward-compatibility guarantees, so those changes are not individually logged.
entries:
- version: v2.1
  date: null
  status: current, stable, production ready
  breaking: true
  summary: >-
    The v2.1 release of the Explore API. The vendor states plainly that "some of
    them may not be backward compatible with the previous version".
  removed_endpoints:
  - path: /api/explore/v2.0/<source>/datasets/<dataset_id>/aggregates
    replacement: merged into the records endpoint
  - path: /api/explore/v2.0/<source>/datasets/<dataset_id>/query
    replacement: merged into the records endpoint
  changed_response_schemas:
  - /api/explore/v2.1/<source>/datasets
  - /api/explore/v2.1/<source>/datasets/<dataset_id>
  - /api/explore/v2.1/<source>/datasets/<dataset_id>/records
  - /api/explore/v2.1/<source>/datasets/<dataset_id>/records/<record_id>
  additions:
  - group_by is now available on the export endpoints.
  - New full-text functions suggest() and startswith().
  - >-
    Geometry functions renamed to clearer names — within_distance(), intersects(),
    disjoint(), within(); the old distance() and geometry(...) forms still work.
  breaking_changes:
  - XLSX export format replaces the old XLS format.
  - The search() function has been changed.
  - >-
    Date functions year(), month(), day(), hour(), minute(), second() now return
    integers instead of strings.
  - Grouping by geo fields is deprecated in favour of the geo_cluster() function.
  - In a group_by, null values are now grouped.
  - Date aggregation keys are formatted as ISO dates, previously as timestamps.
  - CSV exports emit a Byte Order Mark (BOM) by default.
  - GPX exports use <extension> rather than <desc> by default to export attributes.
  - >-
    Datetimes in GeoJSON exports are output as ISO-format strings, previously as
    integer timestamps.
- version: v2.0
  date: null
  status: superseded but still served on this domain
  breaking: false
  summary: >-
    Previous generation of the Explore API, still live at
    https://electricitynorthwest.opendatasoft.com/api/explore/v2.0 with its own
    OpenAPI document. No separate changelog is published for it; its responses
    carry the ODS-Explore-API-Deprecation header pointing at the v2.1 changelog.
catalogue_change_feed:
  note: >-
    Dataset-level change is published separately from API change. The catalogue
    RSS export and the sitemap <lastmod> values are the only signals that the 146
    datasets have been updated.
  rss: https://electricitynorthwest.opendatasoft.com/api/explore/v2.1/catalog/exports/rss
  sitemap: https://electricitynorthwest.opendatasoft.com/sitemap.xml
gaps:
- No dated release entries — impossible to tell when v2.1 shipped from this document.
- No ongoing changelog for the weekly/monthly non-breaking changes the vendor claims.
- No provider-specific changelog for the SP Electricity North West catalogue itself.
