Deep Agents v1.9.0-alpha.0
Deep Agents v1.9.0-alpha.0 introduces async subagents and a new backend protocol v2 with structured result types and multi-modal file support.
This update allows for non-blocking background tasks and enables agents to work with multi-modal files natively, with key changes including simplified method names and backward-compatible changes to the Deep Agents backend interface. The v1 interfaces are deprecated but retained for compatibility.
