Full changelog
2.0.0 (2026-05-19)
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.
