# Changelog

> Changes to the Dcycle API, newest first

Additive changes may ship without notice; anything that can break an integration is listed here first.

## 2026-10-05

* **Deprecated:** `POST /v1/wastes`, superseded by [`POST /v2/wastes`](/api-reference/wastes/create-v2). It keeps
  working and now answers with `Deprecation` and `Link: </v2/wastes>; rel="successor-version"` headers. No removal
  date yet; it will be announced here with notice.
* **Deprecated:** `POST /v1/waste/bulk-delete`, superseded by [`POST /v2/wastes/delete`](/api-reference/wastes/delete-v2)
  (asynchronous, idempotent). Same headers, no removal date yet.
* **New:** [Errors](/api-reference/errors) in v2 follow RFC 9457 problem details (`application/problem+json`) for
  `/v2/wastes`, `/v2/ingest-jobs` and `/v2/webhook-endpoints`. **Breaking for those BETA endpoints:** rejected records
  moved from `detail.records` to `errors`, and validation errors from `detail` to `errors`.
* **New:** v2 timestamps are UTC with `Z` (`2026-10-05T09:35:07.921Z`).
* **New:** [`GET /v2/ingest-jobs`](/api-reference/ingest-jobs/list) lists your jobs; `POST /v2/wastes?dry_run=true`
  validates without writing.
* **Fixed:** `X-RateLimit-Limit` now reports the bucket capacity, so `X-RateLimit-Remaining` never exceeds it; the
  IETF `RateLimit` and `RateLimit-Policy` headers are added ([Rate limits](/api-reference/rate-limits)).
* **New:** [OpenAPI document](/api-reference/openapi-sdks) of the v2 API, for SDKs and Postman.
* **New:** [`POST /v2/wastes/delete`](/api-reference/wastes/delete-v2): asynchronous bulk delete as an ingest job.
* **New:** [Retry Webhook Delivery](/api-reference/webhooks/retry-delivery), and `api_version` in every event.

## 2026-10-01

* **New:** [Webhooks](/api-reference/webhooks/overview): signed `ingest_job.finished` events with retries.
* **Breaking (BETA):** `Idempotency-Key` is required on `POST /v2/wastes`; the same key with a different body is
  `422 IDEMPOTENCY_KEY_REUSED`.

## 2026-09-29

* **New:** [`POST /v2/wastes`](/api-reference/wastes/create-v2) (BETA): up to 5,000 wastes per request, validated
  as a whole, calculated asynchronously as an [ingest job](/api-reference/ingest-jobs/get).
