# Essential Nutrient Web SDK 2024.1 migration tips

[Nutrient Web SDK 2024.1](https://www.nutrient.io/blog/pspdfkit-web-2024-1-ltv-support-for-digital-signatures/) introduces some new APIs and includes several bug fixes. To determine if you need to take action, check your implementation and refer to the information below.

## Notable changes

The following sections outline notable changes in Nutrient Web SDK 2024.1.

### New Document Editor UI API extension

With the extension of the `DocumentEditorFooterItem` and `DocumentEditorToolbarItem` models, it’s now possible to modify the operations manually applied in the document editor UI in the `onPress()` callback. However, the new `onPress()` callback signature has been slightly modified, and you may need to update your implementation, like so:

```diff

- onPress: (event: Event, id?: string) => void;

+ onPress: (event: Event, documentEditorUIHandler: NutrientViewer.DocumentEditorUIHandler, id?: string) => void;

```

The change is trivial: the optional `id` property will now be provided as a third argument instead of a second argument.

## Migrate PSPDFKit Server

Minimum Document Engine version required: 2024.1.0

For information on PSPDFKit Server migration, see [PSPDFKit Server 2024.1 migration guide](https://www.nutrient.io/guides/product-archives-and-deprecated-solutions.md).
