By enabling these options and providing guidance on when to use (or avoid) each special tool, your agent will intelligently enhance interactions with visual tools like buttons, cards, and carousels.

Note: these configurations are ignored during phone-based conversations, meaning it will not prohibit your ability to create multi-modal AI agents with Voiceflow.

Legacy log traces are no longer supported, which are sent when with the query parameter ?log=true.
This system has not been updated for a significant period and is out of date, especially with new steps.

log traces will no longer be returned, after Friday, July 4th, 2025.

This affects a small subset of users and should not impact the output or performance of an agent.

Going forward, it will be unified with a more robust debug trace system, along with a new debugger UI.

We've added Cartesia to Voiceflow. You can select from over 100 new voices across two Cartesia models (Sonic 2 & Sonic Turbo).

We've added all tool types to your projects analytics dashboard:

• Integration tools
• API tools
• Function tools

You can now see the number of times each tool has been used, along with the average latency and success/failure rate if you hover a specific tool.

• We've made updates to the workspace dashboard to make it easier to organize your projects, and manage your workspace.
• We've added folders, to further organize your projects. Note, if you previously used the Kanban view (deprecated), we've automatically converted swim-lanes into folders.
• Home tab (coming soon)
• Community tab (coming soon)
• Tutorials tab (coming soon)

We've listened to your feedback and made Voiceflow easier to navigate. It's the same Voiceflow, just faster to get around!
