Full Changelog: 0.11.7...0.11.8

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

0.11.5

⭐ Highlights

Configure project settings on a per-notebook basis, by inlining as script metadata (PEP 723):

# /// script
# [tool.marimo.runtime]
# auto_instantiate = false
# on_cell_change = "lazy"
# [tool.marimo.display]
# theme = "dark"
# cell_output = "below"
# ///

Note: script metadata configuration has the highest precedence, followed by pyproject.toml configuration, then user configuration.

0.11.0

Highlights ⭐

1. SQL Engine Support. Connect to various databases like postgresql, mysql, snowflake and more, using your preferred SQL engine.

This release adds support for using for multiple SQL connection libraries, such as SQLModel and SQLAlchemy. You can now define SQL connections in your code like:

import sqlalchemy
import sqlmodel
import duckdb

# Create an in-memory SQLite database with SQLAlchemy
sqlite_engine = sqlachemy.create_engine("sqlite:///:memory:")
# Create a Postgres database with SQLModel
postgres_engine = sqlmodel.create_engine("postgresql://username:password@server:port/database")
# Create a DuckDB connection
duckdb_conn = duckdb.connect("file.db")

And then select which connection to use in the SQL cell.

h/t @Light2Dark

2. Markdown file-format improvements - Markdown notebooks (i.e. marimo edit notebook.md) has an improved syntax format: python {.marimo}. You can also use SQL cells in the markdown file-format, using sql {.marimo}. To learn more, run marimo tutorial markdown-format
