# Migrate to Chainlit v2.3.0

## Updating Chainlit

Begin the migration by updating Chainlit to the latest version:

```bash theme={null}
pip install --upgrade chainlit
```

## What changes?

Chainlit 2.3.0 adds the ability to render [Steps](/api-reference/step-class) expanded by default using `cl.Step(default_open=True)`. The chosen value is persisted in a new `defaultOpen` column in the `steps` table.

Full changelog available [here](https://github.com/Chainlit/chainlit/blob/main/CHANGELOG.md).

## How to migrate?

### 1. Update the database schema

A new `defaultOpen` column must be added to the steps table.

<Tabs>
  <Tab title="Official data layer">
    The [Official data layer](https://github.com/Chainlit/chainlit-datalayer) Prisma schema has not been updated to include this column. Run the following migration manually against your database:

    ```sql theme={null}
    ALTER TABLE "Step" ADD COLUMN IF NOT EXISTS "defaultOpen" BOOLEAN;
    ```
  </Tab>

  <Tab title="SQLAlchemy / Custom SQL">
    ```sql theme={null}
    ALTER TABLE steps ADD COLUMN IF NOT EXISTS "defaultOpen" BOOLEAN;
    ```
  </Tab>
</Tabs>

<Note>
  DynamoDB users do not need to run any migration — the schema is dynamic.
