# v4.21

## Release highlights <a href="#v4.20-releasehighlights" id="v4.20-releasehighlights"></a>

### 1. Domains in quality rules <a href="#v4.20-1.taggingdatastructures" id="v4.20-1.taggingdatastructures"></a>

Starting with v4.21 all quality rules will need to be assigned a domain. This will improve the permissions management for quality rules, not depending only on whether a concept has been assigned to the rule. When creating a new quality rule we will have two cases:

* **Quality rules created from a business concept**: The domain of the concept and the corresponding concept will be automatically assigned to the quality rule.
* **Quality rules created from the Data Quality module**: Users must select a domain to be assigned to the rule. Only domains in which the user has permission to create a quality rule will be displayed. Once the domain has been selected it will be optional to select a business concept. In case that a business concept needs to be selected the list displayed will be filtered with the domain previously selected.
