Concise monthly summary of key accomplishments for May 2026 focused on delivering business value and improving system stability. The month centered on a major product release, stability enhancements across tools, and improved dependency management. Highlights include a successful GA release of ADK 2.0.0 with an updated release workflow, enabling legacy v1 patch releases via a v2-aware strategy and removing unnecessary auto-sync to the v2 branch. This reduces release risk and simplifies maintenance while accelerating time-to-market. In parallel, improvements to the MCP tool introduced a graceful error handling feature toggle (enabled by default in later builds) with added tests and exception retrieval for background tasks, stabilizing live sessions. GCS evaluation performance was improved via lazy imports and better handling of missing optional dependencies, reducing startup cost and guiding users when optional components are not installed. The team also tightened dependency management through clearer guidance for optional dependencies and an explicit ImportError flow for missing a2a-sdk in AgentRegistry, resulting in faster, clearer error feedback during development. Protocol handling for Gemini 3.1 Flash Live was fixed to ensure proper history and response handling during live connections. Finally, CI workflows were stabilized by increasing the Python unit test timeout to 10 minutes, reducing flaky runs and improving failure visibility.

The work enabled richer context propagation to Vertex AI, improved reliability of streaming data paths, and reduced risk of silent errors in production.

May 2025 monthly highlights across the Gen AI SDKs and samples. Key features delivered include Vertex AI Global Location support in googleapis/js-genai with URL/auth normalization and defaulting to the global endpoint when appropriate, improving regional/global routing and developer experience. Public API exposure: LiveMusicSession type across the music module for better typing and integration in main/index/node/web entry points. Real-time music reliability improved through a bug fix that correctly parses Blob-received JSON for WebSocket messages. Major quality and stability improvements include making MCP imports optional and clarifying MCP support status in googleapis/python-genai README, reducing dependency-related failures and clarifying experimental status. Gemini API schema robustness improved by removing unsupported additionalProperties and ignoring struct types, preventing runtime errors in googleapis/python-genai and Shubhamsaboo/adk-python. Additional documentation and type-safety enhancements across the Go and Java SDKs, including Go Gen AI SDK README expansion and Java Gen AI README release-status alignment; Gen AI Core type definitions for prompt templates and EvalRunInferenceConfig in googleapis/python-aiplatform, and EvalCase support in EvaluationDataset, improving developer experience and type safety.
