# Release 5.6.2

> Integrators configure agent tools directly in the Constructor. Large Telegram videos send without the usual “failed to fetch” style error. Thematic list fields keep stable internal values for options. The Constructor main menu opens the right bot and behaves correctly in a new tab or window.

## Fast Line Lite

**New**

- **Tool catalog and binding to the agent.** Browse available tools and manage the list on the agent in the module UI (aligned with Fast Line Pro).

**Improved**

- **Catalog unavailable.** When the tool catalog cannot be loaded, you see an explicit error instead of an empty list with no explanation.

## Channels / Telegram

**Fixed**

- **Video from URL.** Large remote videos use an upload path that fits Telegram limits; oversized files return a clear size message.

## Operator Line — thematic fields

**Improved**

- **List fields.** Option values are stored as stable internal codes; labels stay readable in the chat, including for older records.

## Constructor — main menu

**Improved**

- **Menu links.** Middle-click and Ctrl/Cmd-click open the right screen in a new tab; navigation stays on the selected bot instead of jumping to the welcome page.

- **Fast Line entry.** Depending on your environment settings, Fast Line can open the updated agents management screen.
