Highlights ⭐

- Latex completions in markdown mode
- Environment variables are automatically loaded dot-env files (e.g. `.env`) next to your `pyproject.toml`. You can customize this with:

toml
[tool.marimo.runtime]
dotenv = [] don't load any
dotenv = [".env"] default
dotenv = [".env", ".env.production"] load multiple

- Support for using argparse and simple-parsing in marimo notebooks: letting you make notebooks that double as scripts with help messages and argument validation. See [our examples](https://github.com/marimo-team/marimo/tree/6f8d6cb94c6f1d9a85f5abfc04208cbbd0a1d179/examples/running_as_a_script) and [documentation](https://docs.marimo.io/guides/scripts/) to learn more.

This feature was contributed by lucharo!

Breaking changes

1. This release contains a small breaking change. `sys.argv` is now patched to the args after the marimo command

For example, for

bash
marimo edit notebook.py -- foo bar -baz 42

`sys.argv` would be set to

bash
["notebook.py", "foo", "bar", "-baz", "42"]


2. Environment variables are loaded from your `.env` by default. This can be removed through configuration.
