Recently, Dash released version 2.18.0. To install the latest version, use the following command:

pip install dash -U

Version 2.18 introduces several important features, making it easier to develop Dash applications. Let’s explore the key updates:

Global/Local Callback Error Handling

Starting from version 2.18, Dash added a global/local error handling mechanism for callbacks. This allows you to handle errors in a more unified and convenient way by using custom error-handling functions.

Global Error Handling

For global error handling, you can write a custom function. The first parameter of this function will receive the error, and you can assign it to the `on_error` parameter in `dash.Dash()`.
