**🤖🛢 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.

**Full Changelog**: https://github.com/marimo-team/marimo/compare/0.8.4...0.8.5

What's Changed

This release rides on the coattails of the [uv package manager](https://github.com/astral-sh/uv) 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](https://peps.python.org/pep-0723/)! 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:

python
/// 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

bash
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](https://docs.marimo.io/guides/theming.html); 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).
