# June 9 - Follow the rules (0.1.23)

### 📜 Mito Rules

* Mito rules let you add your own reusable instructions to Mito AI. Use it for things like code preferences and project context. 

### 👣 Notebook Footer

* The new notebook footer let's prompt the Mito AI agent without leaving the notebook.
* Add a new Python or Text cell to the bottom of the notebook from the notebook footer.

### 💬 More Databases

* Mito AI learned about new databases, including MySQL, PostgreSQL, and SQLite.

### 🐛 Bug Fixes & Improvements&#x20;

* Clear the variable manager on kernel restarts, so the Ai doesn't think variables exist that don't.
* CSV and Excel files from the current working directory are now displayed in the @ mention dropdown.
* Turns off the default dataframe output mitosheet renderer. You can still view your dataframes in the mitosheet by launching a new mitosheet and importing your dataframes.&#x20;
