What's Changed
This release adds support for OpenAI's Codex agent in the AI chat sidebar, improves Altair chart interactivity, and includes important bug fixes and performance improvements.
Codex Agent Support
Use OpenAI's Codex agent in the AI chat sidebar by selecting "Codex" from the agent dropdown. The agent can help with code editing, debugging, and notebook modifications.
Altair and Vega-Lite Enhancements
Marimo now uses Vega-Lite 6. Charts support legend-based selection in composite charts (layered, vconcat, hconcat), binned data selection, and images in tooltips. Table charts are now faster and handle string columns with up to 20k rows.
