**🔢 🔎 Filter dataframes without writing code!** You can now filter columns in `mo.ui.table` without writing any code: just click on the column header to add a filter. Filters stack into logical ANDs, and can be used in conjunction with global search.

This feature supports Pandas and Polars dataframes.

What's Changed

Highlights

**🔢 No-code Polars transformations!** Polars is now supported in [`mo.ui.dataframe`](https://docs.marimo.io/guides/dataframes.html#transforming-dataframes): transform Polars dataframes without writing code!

**🔍 Searchable tables!** We now have global search over dataframes and other tabular data, built into [`mo.ui.table`](https://docs.marimo.io/api/inputs/table.html)!

**🔔 Notebook run notifications.** At marimo, the small details are important to us: your notebook favicon will now change based on whether your notebook is running or idle. We also have opt-in browser notifications on your notebook status -- so you can navigate away to another tab, and marimo will tell you when your notebook is done running (and if it errored).

**Experimental strict execution.** Reproducibility is important to us; we now have an [experimental "strict" runtime](https://github.com/marimo-team/marimo/pull/1580) that tries hard to prevent mutations and other non-deterministic behavior. Enable it with

toml
[experimental]
execution_type = "strict"


in `~/.marimo.toml`.
