marimo - 0.8.15 Latest Release

Published by akshayka about 1 month ago

What's Changed

Highlights

📸 Automatically snapshot notebooks as HTML This release includes a notebook-level configuration that, when enabled, periodically and automatically snapshots your notebook as HTML, saving the snapshot to a folder .marimo in the notebook directory.

This allows you to enjoy the best of both worlds — your notebooks are stored as pure Python, while your outputs are automatically stashed to a directory for later viewing.

📦 Packge sandbox improvements. We've simplified marimo's package sandbox: now, when you open a marimo notebook with

marimo edit --sandbox notebook.py

marimo will automatically track the packages used by your notebook and save them in the notebook as inline script metadata, along with their versions.

🐍 IPython/Jupyter compatibility. We've increased our compatibility with Jupyter/IPython rendering, adding support for _repr*_ methods as well as mimebundles.

What's Changed

This release adds --sandbox as a flag to marimo new, meaning you can create empty notebooks with sandboxed venvs from the CLI

marimo new --sandbox

This can be helpful when using marimo as a scratchpad.

🤖🛢 An AI assistant that knows your dataframe/table schemas. Starting with this release, marimo's built-in AI assistant doesn't just understand your code -- it also understands your data. When you use our "Generate with AI" feature to generate code, you can now give the AI context about your dataframe and table schemas by tagging it in your query with @dataframe ....

To get started with our AI assistant, visit our docs: https://docs.marimo.io/guides/editor_features/ai_completion.html#using-ai-to-modify-cells

📆 New date components. We've added two new date components: mo.ui.datetime and mo.ui.date_range.

🖊 Realtime markdown rendering. Markdown cells now render as you type!

🛢 Ibis support in mo.ui.dataframe. Transform Ibis dataframes without writing code using mo.ui.dataframe.

Highlights

SQL Reactivity! ⚡🛢 This release adds reactivity across SQL cells. When you run a cell that creates a table or view, or attaches a schema, cells that refer to the table, view, or schema are marked as stale. When you delete a cell, any in-memory tables/views are dropped and schemas are detached, and SQL cells referring to them are invalidated.

Published by akshayka about 2 months ago

What's Changed

This release rides on the coattails of the uv package manager to introduce exciting new features related to package reproducibility!

With this release, it's now possible to create standalone notebook files that have package requirements embedded in them as a comment, using PEP 723's inline metadata! marimo can generate these requirements for you and even start notebooks in isolated virtual environments.

These features are only possible because unlike Jupyter notebooks, marimo notebooks are stored as pure Python files, letting them take advantage of the exciting new developments in the Python ecosystem such as uv and PEP 723.

Highlights

📦 Automatic tracking of packages used by notebooks. marimo can now automatically serialize package dependencies in notebook files as inline script metadata, generating a comment header that looks something like this:

# /// script
# requires-python = ">=3.11"
# dependencies = [
#     "pandas",
#     "altair",
# ]
# ///

This lets you create standalone notebook files that have their package requirements serialized in them.

Enable package tracking in the notebook settings:

Note: This feature requires uv.

🚀 Run marimo notebooks in package sandboxes. Use

marimo edit --sandbox notebook.py

to edit a Python notebook in a completely isolated virtual environment! This increases reproducibility and helps prevent environment pollution. If your notebook has inline script metadata, marimo will automatically install the enumerated packages before running the notebook; if it doesn't, marimo will prompt you to install the missing packages on notebook startup.

This exciting new workflow is only made possible thanks to uv, which is blazingly fast.

Other improvements

  • You can now customize marimo CSS; customization is limited today but will grow over time.
  • Dataframe rows are now paginated server-side, improving performance of notebooks that output alrge dataframes.
  • ANSI color support is now available in stderr.
  • A dedicated "stop" button has been added to the marimo editor, making interrupting cell execution more reliable (no more accidentally running a cell after interrupting it).

What's Changed

Highlights

🏃 Fewer cell re-runs when importing modules. In version 0.8.0, marimo minimizes cell re-runs when importing modules: if you incrementally add imports to the same cell, only cells depending on the newly imported modules will run. This means that you can now collect all your imports in a single cell without having to worry about marimo running cells unrelated to the new imports. Learn more here: https://github.com/marimo-team/marimo/pull/1955

👌 Quality-of-life improvements. Toggle presentation view from the notebook menu; use Meta+z to undo cell deletion; faster table loads for large tables; create files and folders from the file explorer; undo splitting cells; and more!

Return to notebook directory page. If marimo was launched with marimo edit, the notebook menu will now include an option that lets you return to the notebook directory with one click.
