# 2025-09-24: Client Management Service – added a new contact assignment type

## Overview

We've added a new contact assignment type: *Contact* to the Client Management service.

New validation rules:

* Customer can be assigned to a legal entity only once, regardless of the assignment type.
* New assignment type has been added: *Contact*. This is now the default value.
