ADK 2.0 General Availability

This release introduces v2.0.0 General Availability (GA) of the Google Agent Development Kit (ADK), establishing production-grade foundations for multi-agent workflows and advanced dynamic agent collaboration.

Core Architecture Highlights

Multi-Agent Workflow Engine

• Flexible Execution Graphs: Establishes a model-agnostic engine for orchestrating non-linear, conditional, and cyclical agent execution patterns.
• Intelligent Task Delegation: Introduces modular workflow abstractions enabling parallel sub-agent workers, nested hierarchical team structures, and resilient dynamic scheduling across complex task execution steps.

Dynamic Agent Collaboration

• Native Inter-Agent Routing: Provides seamless orchestration for inter-agent messaging, control state handoffs, and context variable propagation across collaborative multi-agent flows.
