# February 2026

> Vellum platform updates for February 2026

## Custom Interfaces for Chat Agents

**February 4th, 2026**

You can now generate custom interfaces for your Chat Agents. Access the new "Preview" mode from the Workflow Sandbox toolbar and build your interface by chatting with Vellum. The interface code is versioned and deployed alongside your Workflow, so publishing your Chat Agent also publishes its interface. You can update the interface independently of the Workflow.

## Microsoft Teams Integration

**February 3rd, 2026**

[Microsoft Teams](https://www.microsoft.com/) is now available as a native integration. Connect your Microsoft Teams workspace to Vellum and use it in your Workflows—send messages, post to channels, and more through Agent Nodes or Custom Nodes.

## Native Integrations Grouping

**February 3rd, 2026**

The Integrations page now groups native integrations by Enabled and Disabled, making it easier to see which ones are ready to use with your Agents.

## Message Queueing

**February 2nd, 2026**

Agent Builder now supports message queueing during response generation. Send multiple instructions in advance, pause sending them, and let them run automatically once the current response finishes.
