# 2.15.0

## Summary

This Version delivers a series of important improvements focused on increasing Matching accuracy, strengthening system reliability, and simplifying Integration flows. The Matching engine has been improved to handle both the absence of side matches (side match) and the existence of multiple matches more intelligently, resulting in more consistent and predictable behavior. Document processing has also been improved by updating PER templates and automatically selecting the most appropriate document mode.

## New features

* Improved Matching logic: the system no longer returns an error when no side match (side match) is found.
* Improved Matching behavior when multiple matches are detected.
* Updated PER document templates.
* Integrated facephi-rest-client.

## Fixes

* Errors are now reported in the correct order in which they occur, to improve traceability.
* Improved identity document processing by automatically using the most appropriate document mode when available.
* Added source type information in the universal output.
* Removed the facephi-flow dependency to simplify the architecture and reduce potential conflicts.
