# Release 5.5.3

> You can edit extra widget JavaScript from the bot settings tab in a dedicated editor.
> For widget dialogs, statistics store platform type (web vs app).

## Bot settings

**New**

- **Custom widget JavaScript.** The Hooks section exposes an editor and save flow; the script is served on a dedicated path for embedding on your site.

## Statistics

**New**

- **Platform source for the widget.** Statistics for the widget channel store a value such as web or mobile app for reporting and KPI filters. By default the widget sends basic visitor metadata; you can override the value via widget init parameters on your site — see widget documentation.

## Scenario Builder

**Improved**

- **Workspace and property panel.** Scenario height aligns with the top chrome; you can drag the border between the canvas and the node inspector, and the inspector width is remembered between sessions.

## Operator Line and operator panel

**Fixed**

- **Leaving Operator Helper.** Full page reload runs only after the router confirms navigation to the target URL — no premature refresh mid-navigation.

## Dialogs (scenarios)

**Fixed**

- **Clear constants action.** A comma-separated prefix list with spaces (`foo, bar`) clears both prefixes; empty segments are ignored.

## Email and contacts

**Improved**

- **Background Gmail and Outlook mailbox polling** runs every 30 seconds instead of 15 — fewer provider requests while mail delivery behaviour stays the same.

**Fixed**

- **Duplicate contact search.** Very short emails and phone numbers do not trigger overly broad database scans; if a heavy query is cut off, the response asks you to refine criteria instead of hanging.

## Fast Line

**Improved**

- **Variation storage for Fast Line** uses an infrastructure-aligned storage path — fewer failures when updating the knowledge base.
