# v5.1

## Release highlights <a href="#v4.23-releasehighlights" id="v4.23-releasehighlights"></a>

### 1. Data Market: avoiding duplicated grants&#x20;

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.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.truedat.io/v8.4/release-notes/v5/v5.1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
