# 1.1.1

**Release date:** March 30, 2026

## General overview

**Facephi IAD Service 1.1.1** is a patch version that updates the IAD engine to version 2.5.3 and fixes documentation issues identified after version 1.1.0. This is a fully backward-compatible release: there are no incompatible changes in the API or configuration.

## Changes

### Engine update

* **IAD Engine 2.5.3** — The IAD detection engine was updated from 2.5.2 to 2.5.3, incorporating the latest fixes and improvements at the engine level.

### Documentation fixes

* **Docker registry paths** — All documentation now consistently references the correct registry path (`docker-pro-fphi`) consistently in the installation guides, release notes, and quick start examples.
* **OpenAPI specification** — The Swagger schemas were updated to accurately reflect the actual request and response structures of all endpoints (`CheckCaptureResult`, `ExtractImageResult`, `MessageResult`, `ConfigData`, `ConfigUpdateRequest`, `BadRequestResult`, `ExceptionResult`).
* **API documentation** — The quick start guide was improved with examples of the configuration and status check endpoints, typical response payloads, and corrected default configuration parameter values.

## Upgrade guide

This version does not require migration steps. The files `config.json` existing ones, and API clients continue to work unchanged. Simply update the Docker image tag to `1.1.1`.
