## Features

* Introduced an artificial intelligence agent that provides a conversational [chat](/app-builder/build-frontend/widgets/display-widgets/chat.md) interface and an initial [RAG AI](/app-builder/build-backend/functions/extensions/rag-ai.md) implementation.
* Expanded connection highlighting in the [App Builder](/app-builder/overview.md). Highlighting works in all directions across the Backend Builder and Frontend Builder. Inputs can now receive data from multiple and mixed sources.
* Animated logos on [functions](/app-builder/build-backend/functions.md) now visualize active data updates in real time.
* Added support for commenting on functions.
* Improved the user interface when working with large input objects.
* Automatically creates a [tag](/app-builder/deploy-and-maintain.md) of your App for each new deployed version.

## Fixes

* Improved snapline behavior: Snaplines now react only to visible widgets and appear during resizing. Widgets now snap to a 10px grid for easier alignment.
* Fixed screen scaling for mobile and tablet devices on [Production Apps](/production-apps/overview.md) and optimized rendering performance.
* Resolved several issues in the [OGC SensorThings API](/app-builder/build-backend/functions/extensions/ogc-sensorthings-api.md) extension.
* The App installation prompt now only appears on platforms that support Progressive Web Apps (PWAs).
* Removed the buggy undo and redo features.

## 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.heisenware.com/release-notes/v77-more-intelligence.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.
