⭐ Highlights

🤖 Chat sidebar is now GA.

📈 mo.ui.altair_chart now used Arrow instead of CSV for its over-the-wire format. This has tradeoffs: memory consumption is lower, parsing times are faster, but download time could be longer for remote servers. This also improves the type correctness by avoiding guessing the CSV types. Please reach out if you experience any regressions.

0.11.7

⭐ Highlights

🔄 Serialized outputs - when auto-instantiate is off, outputs are stored in __marimo__/session. When you restart you notebook, your outputs will be brought back without running any cells. Every cell is still considered stale, so whenever a cell is run, we run it's ancestors to bring them up-to-date.

💽 Refreshed data-sources panel - The datasources panel now includes an improved hierarchy (Engine > Database > Schema > Table > Columns), more performant loading, lazy-loading, and column metadata like types and primary keys. h/t @Light2Dark
