🧪 Community Feedback: kepler-jupyter v0.4.0 Release Candidate

[lixun910]

Hi Kepler.gl Community! 👋

We’re gearing up for the kepler-jupyter v0.4.0 release (PR #3345). This update transitions the package to a modern stack to ensure better stability in JupyterLab 4+, VS Code, and Google Colab.

What’s Changing?

• Anywidget Migration: We've moved to an anywidget-based implementation. This simplifies the data flow between Python and JavaScript and fixes many "blank map" issues in modern IDEs.
• Modern Tooling: The frontend build now uses esbuild, and the Python environment is managed via uv.

⚠️ Breaking Changes & Removals

• Removal of save_to_html(): This function has been removed due to its complexity and lack of support for the Jupyter protocol.
• Alternative: Use the "Share" button within the UI to export HTML. This ensures the export is feature-equivalent and triggered safely by the user. In this way, users will now need to supply their own Mapbox token for satellite tiles and other Mapbox-hosted styles.

Please test this RC in your specific notebook environment:

pip install keplergl==0.4.0rc1

We need your feedback on:

• Installation: Does it resolve previous dependency conflicts?
• Rendering: Does the map load correctly in your specific environment?

Thank you!
