# Changelog

> What changed in the Delogue API, newest first — added, changed, deprecated, and removed operations.

This page tracks changes to the API surface described in this reference. Entries are dated and
listed **newest first**.

## How to read this page

Each entry groups its changes into up to four sections — only the sections with something to
report for that date appear:

| Section        | Meaning                                                                                                                        |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------ |
| **Added**      | A new endpoint, field, or enum value. Safe to adopt immediately — nothing existing changed.                                    |
| **Changed**    | An existing operation's behavior or documentation changed in a backward-compatible way.                                        |
| **Deprecated** | Still works today, but scheduled for removal. See [Versioning & deprecation](/concepts/versioning) for the transition process. |
| **Removed**    | No longer available.                                                                                                           |

Each line is a one-sentence, plain-language summary naming the affected operation.

## 2026-08-17

This entry adds a large batch of new API surface and refreshes how the shared response and
error envelopes are described. The consumer-facing highlights are below.

### Added

* **Twelve new entities** now appear in the reference — [Barcodes](/guides/barcodes), [Care Instruction Icons](/guides/care-instruction-icons), [Measurement Charts](/guides/measurement-charts), [Organizations](/guides/organizations) (integration access), [Sample Requests](/guides/sample-requests), [Style Care Instructions](/guides/style-care-instructions), [Style Contacts](/guides/style-contacts), [Style Files](/guides/style-files), [Style Prices](/guides/style-prices), [Style Relations](/guides/style-relations), [Style SKUs](/guides/style-skus), and [Style Supplier Facilities](/guides/style-supplier-facilities) — 42 operations in all, each with a task-based guide.
* **Partial-update endpoints** accepting an RFC 6902 JSON Patch document (`application/json-patch+json`): **`PATCH /api/brands/{id}`**, **`PATCH /api/compliance-categories/{id}`**, **`PATCH /api/groups/{id}`**, **`PATCH /api/sample-types/{id}`**, **`PATCH /api/size-ranges/{id}`**, **`PATCH /api/style-custom-fields/{id}`**, and **`PATCH /api/styles/{id}`**.
* **`PUT /api/brands`** — bulk full-replace of [brands](/guides/brands) in a single transaction.
* **`PUT /api/styles/{id}`** — full-replace update of a single [style](/guides/styles); and **`GET /api/styles/{styleId}/size-range`** and **`GET /api/styles/{styleId}/sizes`** — read a style's size range and its sizes.
* **`PUT /api/brands`**, **`PATCH /api/brands/{id}`** — [brand](/guides/brands) writes now accept an optional `logo` file reference.

### Changed

* **Response envelopes are now named schemas.** Success responses use `ApiResponseOf…` / `ApiPaginatedResponseOf…` wrappers and errors use `ApiErrorResponse` / `ProblemDetails`; the documented envelope shape (`{ status, code, data }` for success, `{ status, code, error }` for errors) is unchanged.
* **Error responses are `application/json` only.** The `text/json` and `text/plain` media types were dropped from the `401` and `500` responses across all endpoints.

## 2026-07-07

### Added

* **`PATCH /api/seasons/{id}`** — partially update a [season](/guides/seasons) with an RFC 6902 JSON Patch document (`application/json-patch+json`).
* **`PATCH /api/compliance-custom-fields/{id}`** — partially update a [compliance custom field](/guides/compliance-custom-fields) with a JSON Patch document.
* **`DELETE /api/item-categories`** and **`PATCH /api/item-categories/{id}`** — bulk-delete [item categories](/guides/item-categories) via repeated `ids`, and partially update a single category with a JSON Patch document.
* **`DELETE /api/style-categories`** and **`PATCH /api/style-categories/{id}`** — bulk-delete [style categories](/guides/style-categories) via repeated `ids`, and partially update a single category with a JSON Patch document.
* **`PUT /api/item-categories`**, **`PUT /api/item-categories/{id}`** — the request `state` now accepts the enum values `active`, `inactive`, and `deleted`.
* **`POST /api/items`**, **`PUT /api/items`**, **`PUT /api/items/{itemId}`** — [item](/guides/items) `customFields` entries accept a new optional `values` array for multi-select allowed-value fields and an object for `value`.
* **`GET`/`POST`/`PUT`/`DELETE /api/brands`** — [brand](/guides/brands) responses include a new optional `associatedDesignerOrganizations` on the logo file's `createdBy` user.

### Changed

* **`GET /api/styles`** — added the optional `StyleInfoUpdatedOn` date-range query parameter to filter [styles](/guides/styles) by when their style info last changed.
* Breaking: **`PUT /api/compliance-custom-fields`**, **`PUT /api/compliance-custom-fields/{id}`** — the request booleans `internalOnly`, `isMandatory`, `isMultiLine`, and `isSortByAllowedValueId` are no longer nullable; on the full-replace `PUT`, omitting one writes `false`.
* Breaking: **`PUT /api/item-categories`**, **`PUT /api/item-categories/{id}`** — the request `state` was restricted to the `active`/`inactive`/`deleted` enum and no longer accepts `null`.
* Breaking: **`PUT /api/items`**, **`PUT /api/items/{itemId}`** — the item `customFields` entry `id` (the custom-field definition id) is now required (non-nullable).
* Breaking: **`GET /api/styles`** — the `ReadyForExport` query parameter changed from an array of integers to a boolean.

### Removed

* **`POST /api/items`**, **`PUT /api/items`**, **`PUT /api/items/{itemId}`** — removed the item `customFields` request properties `customFieldId`, `itemCustomFieldAllowedValueId`, and `customFieldAllowedValueUserDefinedID` (replaced by `id` and the `value`/`values` objects).
* **`POST /api/brands`**, **`PUT /api/brands/{id}`** — removed the `logo` request property; these endpoints no longer accept a brand logo in the request body.
