# Changelog (/changelog)

Additive changes ship without a new version. Breaking changes get a new dated version. See [Versioning](/versioning).

## 2026-11-06 [#2026-11-06]

Additive, in version `2026-11-03`:

- `GET /v1/markets?trend=true` adds `change` (the lowest price's move over `hours`) and `trend` (that price on a
  shared time grid, times in `meta.trend_times`). Every market row now names `low_provider` and `high_provider`.
- New `GET /v1/markets/{gpu}/history/providers`: each provider's price line for a GPU on one time grid, with the
  market low, median and high.
- `GET /v1/listings?previous=true` adds `price_change`: the price before the listing's latest change, and when it
  changed.
- Error `docs_url` now links to the [Errors](/errors) page on this site.
- The API answers CORS requests from this site, so the playground can call it with your key.

## 2026-11-03 [#2026-11-03]
