# v4.55
## Release highlights
### 1. **Data Catalog: Highlighted changes when creating a new version of Notes**
When creating a new version of a Note, those fields that have their values modified will be highlighted when the note is saved so any user reviewing the note can easily identify the changes from the previous version.
Fields in orange have been modified from previous version
### 2. Data Catalog: **Linking structures**
A structure can be linked to another structure from a different system. The information on these relationships between structures can be only loaded via API by a connector. The information then will be displayed in the Data Catalog in a new tab: "Linked structures".

## 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/v4/v4.55.md?ask=&goal=
```
`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.
