# 1.1.0

**Release date:** March 20, 2026

## Overview

**Facephi IAD Service 1.1.0** focuses on operational resilience, configuration flexibility, and better diagnostics. This is a fully backward-compatible version: there are no incompatible changes in the API or configuration.

## What's new

### Improved License diagnostics

* **License error translation** — More than 110 License status codes are now mapped to human-readable messages with actionable recommendations.
* **Standardized error reporting** — License-related failures produce consistent, structured log entries to make troubleshooting easier.

### Docker image hardening

* Simplified base image with reduced attack surface.
* Better package management and dependency pinning.
* Cleaner log output (excess detailed logging was removed in Docker detection and engine startup).

## Bug fixes

* REST proxy errors are now created and reported through a single, consistent code path.
* Engine error responses are normalized before being forwarded to the client.
* Excess debug logging during Docker environment detection was removed.

## Upgrade guide

This version does not require migration steps. The files `config.json` and existing API clients continue to work unchanged.

To take advantage of configuration via environment variables, set the variables `FACEPHI_IAD_REST_*` or `FACEPHI_IAD_ENGINE_*` desired before starting the service or in your Docker Compose / Kubernetes manifest.
