 # Changelog
 
+## [2.0.0](https://github.com/google/adk-python/compare/v2.0.0b1...v2.0.0) (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.
