# v5.1 ## Release highlights ### 1. Data Market: avoiding duplicated grants When creating new grants in Truedat, a unique reference can be included to ensure that no duplicated grants are created. This reference field must be provided by the external system that manages and grant access to the data. Truedat will consider a grant to be duplicated if it is for the same user, same structure, in the same dates and with the same reference.

### 2. Data Catalog: navigation and search When navigating in the Data Catalog, the first 1000 structures are displayed on the left panel but the total number of structures are indicated if there are more than a thousand. Even if they are not displayed in the panel, you can search for them in the search box and they will be displayed.
