AgentFlow v1.4: Multi-Channel Gateway & Streaming Citations
Introducing real-time citation streaming, enhanced Meta Cloud API webhook reliability, and granular role-based permissions in the visual canvas.
By AgentFlow EngineeringVerified for AgentFlow v1.4
Today we are thrilled to announce AgentFlow v1.4, bringing several major enhancements to agent deployment, vector streaming, and enterprise team governance.
Highlights - **Streaming Citations**: As tokens stream into the chat widget, verified source citations appear alongside the text rather than waiting for the complete generation. - **Enhanced WhatsApp Business Gateway**: Upstream retry buffering prevents dropped messages during Meta rate spikes. - **Granular Scoping**: Assign separate editing permissions for prompts, tools, and knowledge sources across team members.
