[Release] google/adk-python v2.0.0: v2.0.0

Google ADK Python v2.0.0 achieves General Availability with production-grade support for multi-agent workflows and dynamic collaboration. The release introduces a flexible, model-agnostic execution engine for orchestrating complex agent patterns including non-linear, conditional, and cyclical workflows. Key features include intelligent task delegation with parallel sub-agent workers, hierarchical team structures, and native inter-agent routing with seamless messaging and context propagation.

Key Points

• •Multi-agent workflow engine supports non-linear, conditional, and cyclical execution patterns in a model-agnostic architecture
