Jun 1, 2025June 2025 monthly summary for mckinsey/vizro focused on delivering a robust AI-driven dashboard while strengthening release discipline and deployment simplicity. Key refactor of the dashboard data model and configuration migrated data handling to Pydantic for validation, updated dependencies, and refined the dashboard graph state to improve robustness and maintainability. Release readiness activities prepared vizro-ai 0.3.7 (including changelog updates, removal of stale fragments, and version bump). Documentation enhancements added Docker-based run instructions for Vizro-MCP to streamline local data mounting and deployment. These efforts reduce risk during releases, improve data integrity, and accelerate AI-driven dashboard creation for business users.

Feb 1, 2025February 2025 (Month: 2025-02) — Delivered and stabilized key Vizro capabilities, focusing on interoperability with Google's LLM ecosystem, performance-conscious rendering, and ecosystem stability. Key deliverables and fixes include: - Gemini/Google LLMs structured output compatibility (bug): fixed parsing of structured outputs from Gemini models and enabled compatibility with Google LLM responses; updated dependencies and example notebooks to reflect integration with Google's generative AI models. Commits: 5e30406929047a39a9a8ce59ab41656b6b2aeb56 (Fix) and 268c63b0368f0c57d98192906d0e7ac8635e21cd (Release, vizro-ai 0.3.4). - Minimal output mode in VizroAI (feature): introduced _minimal_output flag to control verbosity, refactored ChartPlan/ChartPlanFactory to support a BaseChartPlan for minimal output and allow chart_plan argument for flexible output generation. Commits: 42034f5bec53c1be7191ff915385e6b2c6a7fe5f (POC) and 804bb3e6a1fd00c863b1f8426a58a4966f6607a4 (Release, vizro-ai 0.3.5). - Documentation enhancement: actions for custom components (feature): clarified how custom components trigger actions, documented the new 'actions' field and _action_validator_factory to link property changes to actions, enhancing interactivity. Commit: 5d837031c8f51f036e4f7fca250c42576eef99a6. - Dependency compatibility updates (Pydantic v2 and newer ecosystems) (bug): updated dependencies to ensure compatibility with Pydantic V2 and newer versions of langchain and vizro for stability. Commit: 16b18c81babe7e7523e6236bd0d9c08394c4f694 (Release, vizro-ai 0.3.6).
